Earning a Ph.D. from a U.S. grad school typically requires nearly six years, federal statistics show.

(CAIAIMAGE/TOM MERTON/GETTY IMAGES)

A Ph.D. is most appropriate for someone who is a “lifelong learner.” 

Students who have excelled within a specific academic discipline and who have a strong interest in that field may choose to pursue a Ph.D. degree. However, Ph.D. degree-holders urge prospective students to think carefully about whether they truly want or need a doctoral degree, since Ph.D. programs last for multiple years.

According to the Survey of Earned Doctorates, a census of recent research doctorate recipients who earned their degree from U.S. institutions, the median amount of time it took individuals who received their doctorates in 2017 to complete their program was 5.8 years. However, there are many types of programs that typically take longer than six years to complete, such as humanities and arts doctorates, where the median time for individuals to earn their degree was 7.1 years, according to the survey.

Some Ph.D. candidates begin doctoral programs after they have already obtained master’s degrees, which means the time spent in grad school is a combination of the time spent pursuing a master’s and the years invested in a doctorate. In order to receive a Ph.D. degree, a student must produce and successfully defend an original academic dissertation, which must be approved by a dissertation committtee. Writing and defending a dissertation is so difficult that many Ph.D. students drop out of their Ph.D. programs having done most of the work necessary for degree without completing the dissertation component. These Ph.D. program dropouts often use the phrase “ all but dissertation ” or the abbreviation “ABD” on their resumes.

According to a comprehensive study of  Ph.D. completion rates  published by The Council of Graduate Schools in 2008, only 56.6% of people who begin Ph.D. programs earn Ph.D. degrees.

Ian Curtis, a founding partner with H&C Education, an educational and admissions consulting firm, who is pursuing a Ph.D. degree in French at Yale University , says there are several steps involved in the process of obtaining a Ph.D. Students typically need to fulfill course requirements and pass comprehensive exams, Curtis warns. “Once these obligations have been completed, how long it takes you to write your dissertation depends on who you are, how you work, what field you’re in and what other responsibilities you have in life,” he wrote in an email. Though some Ph.D. students can write a dissertation in a single year, that is rare, and the dissertation writing process may last for several years, Curtis says.

[ READ: What Is a Doctorate or a Doctoral Degree?  ]

Curtis adds that the level of support a Ph.D. student receives from an academic advisor or faculty mentor can be a key factor in determining the length of time it takes to complete a Ph.D. program. “Before you decide to enroll at a specific program, you’ll want to meet your future advisor,” Curtis advises. “Also, reach out to his or her current and former students to get a sense of what he or she is like to work with.”

Curtis also notes that if there is a gap between the amount of time it takes to complete a Ph.D. and the amount of time a student’s funding lasts, this can slow down the Ph.D. completion process. “Keep in mind that if you run out of funding at some point during your doctorate, you will need to find paid work, and this will leave you even less time to focus on writing your dissertation,” he says. “If one of the programs you’re looking at has a record of significantly longer – or shorter – times to competition, this is good information to take into consideration.”

Pierre Huguet, the CEO and co-founder of H&C Education, says prospective Ph.D. students should be aware that a Ph.D. is designed to prepare a person for a career as a scholar. “Most of the jobs available to Ph.D. students upon graduation are academic in nature and directly related to their fields of study: professor, researcher, etc.,” Huguet wrote in an email. “The truth is that more specialization can mean fewer job opportunities. Before starting a Ph.D., students should be sure that they want to pursue a career in academia, or in research. If not, they should make time during the Ph.D. to show recruiters that they’ve traveled beyond their labs and libraries to gain some professional hands-on experience.”

Jack Appleman, a business writing instructor, published author and Ph.D. candidate focusing on organizational communication with the  University at Albany—SUNY , says Ph.D. programs require a level of commitment and focus that goes beyond what is necessary for a typical corporate job. A program with flexible course requirements that allow a student to customize his or her curriculum based on academic interests and personal obligations is ideal, he says.

[ READ: Ph.D. Programs Get a Lot More Practical.  ]

Joan Kee, a professor at the University of Michigan  with the university’s history of art department, says that the length of time required for a Ph.D. varies widely depending on what subject the Ph.D. focuses on. “Ph.D. program length is very discipline and even field-specific; for example, you can and are expected to finish a Ph.D, in economics in under five years, but that would be impossible in art history (or most of the humanities),” she wrote in an email.

Jean Marie Carey, who earned her Ph.D. degree in art history and German from the  University of Otago  in New Zealand, encourages prospective Ph.D. students to check whether their potential Ph.D. program has published a timeline of how long it takes a Ph.D. student to complete their program. She says it is also prudent to speak with Ph.D. graduates of the school and ask about their experience.

Bennett urges prospective Ph.D. students to visit the campuses of their target graduate programs since a Ph.D. program takes so much time that it is important to find a school that feels comfortable. She adds that aspiring Ph.D. students who prefer a collaborative learning environment should be wary of graduate programs that have a cut-throat and competitive atmosphere, since such students may not thrive in that type of setting.

Alumni of Ph.D. programs note that the process of obtaining a Ph.D. is arduous, regardless of the type of Ph.D. program. “A Ph.D. is a long commitment of your time, energy and financial resources, so it’ll be easier on you if you are passionate about research,” says Grace Lee, who has a Ph.D. in neuroscience and is the founder and CEO of Mastery Insights, an education and career coaching company, and the host of the Career Revisionist podcast.

“A Ph.D. isn’t about rehashing years of knowledge that is already out there, but rather it is about your ability to generate new knowledge. Your intellectual masterpiece (which is your dissertation) takes a lot of time, intellectual creativity and innovation to put together, so you have to be truly passionate about that,” Lee says.

Erin Skelly, a graduate admissions counselor at the IvyWise admissions consulting firm, says when a Ph.D. students struggles to complete his or her Ph.D. degree, it may have more to do with the student’s academic interests or personal circumstances than his or her program.

“The time to complete a Ph.D. can depend on a number of variables, but the specific discipline or school would only account for a year or two’s difference,” she wrote in an email. “When a student takes significantly longer to complete a Ph.D. (degree), it’s usually related to the student’s coursework and research – they need to take additional coursework to complete their comprehensive exams; they change the focus of their program or dissertation, requiring extra coursework or research; or their research doesn’t yield the results they hoped for, and they need to generate a new theory and conduct more research.”

Skelly warns that the average completion time of a Ph.D. program may be misleading in some cases, if the average is skewed based on one or two outliers. She suggests that instead of focusing on the duration of a particular Ph.D. program, prospective students should investigate the program’s attritition and graduation rates.

“It is worthwhile to look at the program requirements and the school’s proposed timeline for completion, and meet current students to get their input on how realistic these expectations for completion are,” Skelly says. “That can give you an honest idea of how long it will really take to complete the program.”

How Do You Get a PhD? A Guide to the PhD Timeline

Everyone who considers a doctoral degree knows a PhD is a big commitment. 

Not only will it require all your mental energy, focus, and persistence, but it will also require a significant investment of your time. Your particular area of research, your institution’s policies and procedures, and the standard expectations within your field affect how long it takes to earn a PhD. The average PhD length is five or six years, while some students may take eight or nine years.

Regardless of how long a PhD program takes,  there are some common stages of a PhD that all doctoral students share. These significant and essential milestones shape the timeline for earning your doctorate . Read on as we take you through each step and explore the typical steps to a doctorate degree.

How Long Do PhD Programs Take?

The number of credit hours that you need to complete your doctoral coursework might depend on several factors: do you already have a master’s degree? Will you earn one en route to the doctorate? Or do you even need one? 

Different disciplines and research interests have their own PhD process, but even within your field of study, institutions may have diverse pathways for obtaining that terminal degree. For most, coursework will take anywhere from two to three years to complete.

During this time, students can serve as graduate research or teaching assistants or could even lead their own courses as instructors. In many degree programs, students develop their potential dissertation topics through their coursework and define their research plans in the next few years.

Steps to Getting a PhD: PhD Qualifying Exam and Comprehensive Exam

Many programs set up academic checkpoints to help keep students on track during their PhD journeys. The timing varies by program, but one of the most common – and possibly most stressful – forms of benchmarking is the PhD comprehensive exam or qualifying exam. Often administered around the end of the student’s coursework, these exams are your chance to demonstrate what you learned in your classes.

A faculty committee from your department oversees testing. Usually comprised of at least three members, your professors ask questions or assign writing prompts based on your experience in the program thus far. The format is generally a combination of written and oral exams designed to test your expertise in your discipline’s methodologies and significant content areas.

To better prepare yourself, research the number and kind of qualifying benchmarks the program will require in the university catalog before you begin your program. This will allow you and your advisor to effectively plan out the first few years of your degree and give you an idea of how you’ll be evaluated throughout your program.

Doctoral Dissertation Prospectus and Defense

You may be required to complete and defend a dissertation prospectus before officially becoming a PhD candidate. A prospectus is a document outlining your dissertation plan, which includes an explanation of your research topic, a potential outline of your dissertation, the methodologies you intend to employ, the significance of your research question, and a bibliography including sources that form the foundation of your research.

Your prospectus allows your dissertation advisor to understand the scope of your project. It should be thorough enough that they can provide useful feedback to help shape your research plan. After some revisions, an approved prospectus is the green light to move into the next stage of your PhD.

Advancement to Doctoral Candidacy

If you have heard the term ABD – “All But Dissertation” – then that means you are in the home stretch of your doctoral program!

Well, sort of…only your dissertation remains!

Doctoral Dissertation Research and Writing

While you’ve made it through the coursework and qualifying exams, the dissertation is the culminating component of the doctoral degree. At this point, your approved research plan is ready to be set into motion. Depending on your discipline, this could be the stage where you travel extensively to conduct fieldwork, explore archives, or visit labs to collaborate on projects that relate to your dissertation work. For many students, the research phase can take a couple of years, but some may be able to complete it in one.

Writing your dissertation can be one of the most challenging parts of the whole PhD process. Not only are you condensing years of research into a single cohesive document, but you are also formulating graphs, charts, and other textual references to help clarify your argument. Often, formatting can be a major challenge for many students. 

In this stage, it’s most helpful to seek out resources to help you with the writing process. Many universities have dissertation writing workshops where you can learn best practices, as well as support groups where students meet regularly and help keep each other accountable. Most universities also offer competitive dissertation completion grants, supporting students with additional funding so they focus more of their time and effort on completing this undertaking.

Dissertation Defense

Everyone gets nervous about this major rite of passage. It can be difficult to take criticism over something you have poured your heart and soul into for years. Remember, though, that a good advisor will not let you defend if you’re not ready, and you literally wrote the book on your topic!

The dissertation defense is not intended to tear your work apart but rather is your opportunity to prove your expertise to your dissertation committee. Many defenses are open to observers, so you should attend a few in advance of your own, especially within your department, to get a sense of what it’s like. 

First, you’ll present the main points of your thesis. Then the committee will ask questions so they can clearly understand your arguments. Finally, they’ll send you out of the room while they deliberate and decide if you pass or not. If all goes well, you’ll be addressed as “Doctor” the next time you walk into the room!

Get Started on Your PhD Journey Today

No matter what your particular timeline looks like as you work toward your doctorate, know that the faculty and other students within your program are frequently a huge source of support — which means you won't do this alone! Additionally, every school has resources to assist PhD students, from libraries to writing centers to dedicated student support services.

How Long Does It Take to Get a PhD?

If you aspire to rise to the top of your field, then you may have your sights set on a PhD.

Earning a doctoral degree can be a years-long process, but choosing an accelerated doctoral online program may help you complete your program more quickly.

Editorial Listing ShortCode:

Whether you’re wanting to earn one of the highest paying doctoral degrees or you have a specific one in mind, this guide can help walk you through how long it takes to complete your PhD program.

For a traditional, campus-based PhD program, the average time to finish a PhD is 8 years. Fulfilling the program’s requirements will often demand a serious investment of your time.

Even still, some people are able to finish their programs in just 3 to 6 years. Multiple factors may influence the overall length of your program.

Required Credit Hours

Many PhD programs require you to earn 120 credit hours before entering the exam and dissertation phases.

Fortunately, there are PhD programs without such high credit-hour demands. For example, at some universities, you may earn a PhD with only 60 credit hours.

Full-Time vs. Part-Time Schedule

Enrolling in a doctoral program part-time may allow you to keep up with your regular job. You’ll have to decide whether you prefer the flexibility of part-time schooling or the faster schedule of full-time studies.

Final Project Requirements

Many PhD programs end with the completion of a dissertation. This assignment may take years to complete, so PhD students often end up in the all-but-dissertation (ABD) phase for quite some time.

University Scheduling

Some schools promote their ability to help you through the PhD process faster than normal. Accelerated class schedules with eight-week online courses may speed your studies along. Focused attention from dissertation advisors may help as well.

PhD Program Components

Before you enroll in a PhD program, it’s important to know some of the basic requirements:

Prerequisites

Most schools require you to already hold a master’s degree, but some offer bachelor’s-to-PhD programs.

Length to Completion

On average, it takes eight years to earn a PhD. Even still, completing doctoral coursework and a dissertation in three to four years is not unheard of.

Topic of Interest

PhD stands for Doctor of Philosophy, but that doesn’t mean you’ll be getting a philosophy degree. Your field of study will depend on your interests and the programs that your university offers. You may tailor your doctoral focus though your choice of a dissertation topic.

Steps to Completion

You’ll take advanced classes before sitting for comprehensive exams. After passing your exams, you’ll likely begin working on a dissertation. You must defend your dissertation before finishing your program.

Doctoral studies begin with a series of classes through which you may increase your knowledge of your field of study and learn about conducting research. These are advanced classes, so they should be more in-depth than the ones you took during your undergraduate and master’s programs.

The number of courses that you need to take can vary significantly. It’s not uncommon for PhD programs to require 120 credit hours of coursework. That amounts to about 40 classes.

At other schools, the requirements are lower. Your university’s program may involve just 60 credit hours or, possibly, even fewer. A less intense course load may significantly slash your time to completion.

Your university may require you to maintain a GPA above a minimum threshold. An unsatisfactory GPA may keep you from moving on to the next step of the PhD process.

Comprehensive Examinations

Universities often require students to demonstrate their readiness for a doctoral project before advancing to the next stage of their studies. Readiness is proven through comprehensive exams , which may also be known as:

• Preliminary examinations
• Major field examinations
• General examinations

Often, comprehensive exams take the form of written or oral tests. In other situations, faculty may assess students’ readiness on the basis of a portfolio evaluation or a written paper.

Dissertation and Defense

A dissertation, also known as a graduate thesis, is a body of work that presents original research in your field. This manuscript focuses on a unique idea and includes evidence to support your thesis. During your doctoral studies, there are classes designed to help prepare you for your dissertation work.

The dissertation process may take several years. Once your manuscript is complete, you must defend it to the doctoral program faculty. After your defense, you may need to do further work on your manuscript, or the committee may decide that your dissertation is complete.

Not all programs require a dissertation. Instead, there may be an alternative doctoral project. Although both dissertations and capstone projects are rigorous, projects can sometimes be completed within a shorter time frame.

Average Time to Complete PhD by Field of Study

Students in some disciplines usually take a lot more time to finish their doctoral work than students in other fields.

If you’re studying in the following scientific fields, you may be more likely to earn your on-campus degree in seven years or less:

• Physics — average of five years
• Psychology — average of five to seven years

On the other hand, if your field of study relates more to the humanities, your on-campus degree program may take longer:

• History — average of eight years
• English — average of eight years
• Education — average of 13 years

These are the traditional figures. There are ways to finish faster.

Why Does It Take So Long to Finish a Traditional PhD?

Some schools require doctoral students to take around 40 classes, which, in a traditional on-campus setting, may take years. After completing the coursework, you must write your dissertation and defend it. The dissertation process alone might take multiple years.

Doctoral programs online may help shorten the PhD process to three or four years. Fewer credit hours may be required, and the classes may be delivered in an accelerated format.

Schools with an emphasis on quick doctoral programs may also offer dissertation advisors to efficiently guide students through that phase. Alternatively, some universities allow students to complete capstone projects that don’t take as long as dissertations.

Getting a PhD Online vs. Campus

Online education has changed students’ options for earning a PhD. These days, aspiring students may choose whether to attend classes on a college campus or online.

Traditional programs may require you to relocate to the university’s campus and attend school full-time. On average, it takes just over eight years to complete those programs. The benefits of choosing an online school instead may include:

Faster Progress

Accelerated eight-week courses may allow you to finish your course load sooner. You may complete your entire program in just three or four years.

Multiple Start Dates

Online programs often let you join throughout the year, so you don’t have to put your studies on hold until the fall semester.

Flexibility

Not being required to move to campus or come to class at set times may allow you to work your studies around your schedule.

Equal Status

Online programs are just as rigorous as on-campus ones. As long as your university is accredited, your degree will be just as valuable as one from a traditional university setting.

Cost-Savings

Finishing your doctoral studies faster may mean that you pay less tuition.

How to Finish Your PhD in Less Time

Although you can’t earn a doctoral degree overnight, you shouldn’t have to spend the majority of your working years striving toward PhD-completion. The following tips for accelerating the PhD process may help you finish your studies more quickly than the average doctoral student.

1. Use What You Already Know

Every school requires a minimum number of credit hours that you must earn in the pursuit of your degree. To help you meet this threshold, some schools will allow you to transfer in credits from other doctoral programs. Universities may also give you credit for your professional experience. Reducing your class load may save you both time and money.

2. Look for Short Classes

Accelerated course schedules are one of the best ways to speed through the degree process. Every eight weeks, you’ll begin a new set of classes. Over the course of a year, there may be five different sessions during which you can take classes.

3. Work on Your Dissertation Throughout the Program

Traditionally, dissertation work begins once the classroom portion of your studies is over. Quick doctoral programs may allow you to begin the dissertation process while you’re still taking other classes. This approach, known as an embedded dissertation, may reduce the likelihood that you’ll drop out before finishing your final project. It might also speed up your doctoral timeline.

4. Ask for Help

A lack of support can lead some doctoral students to drop out. On the other hand, having a good support system can help you push through and finish your program more quickly. Build a team of family, friends, and academic mentors who can encourage you, guide you, and lend practical help when you’re feeling overwhelmed by school.

Why Get a PhD?

You may need to earn a doctoral degree to achieve your career goals . For example, if you want to become a clinical psychologist, this level of study is essential. Many scientific and research positions require doctoral studies. University faculty typically need to hold terminal degrees as well.

Even if a doctorate is not a requirement for your desired line of work, it may help you achieve greater success. You might be granted higher levels of responsibility, and you may earn more money. In some fields, those who hold PhDs make around 20% more than those with master’s degrees, according to the Bureau of Labor Statistics .

Do You Have to Have a Master’s Degree to Get a PhD?

Many schools consider a master’s degree an essential prerequisite for PhD admission. If you don’t already have a master’s degree, a bachelor’s-to-doctorate program may allow you to earn a master’s and a PhD for less time and money than it would take to pursue them separately.

How Long Does It Take to Get a PhD After a Master’s?

You may be able to complete your doctoral program in three to four years if you opt for an accelerated online program. On average, traditional on-campus PhD programs take around eight years to complete.

How Hard Is It to Finish a PhD?

Doctoral studies are challenging. That shouldn’t come as a surprise; if doctorates were easy to acquire, nearly every college graduate would end up with a PhD behind his or her name.

Approximately 50% of students who begin a PhD program don’t end up finishing. Many quit within two years of starting. Another large portion gives up upon reaching the dissertation phase.

Although all PhD programs are challenging, the flexible nature of online programs may help you find success. Choosing a doctoral track that doesn’t require a dissertation may help as well.

What Is the Easiest PhD to Get?

All PhD programs are demanding, but you might have an easier time if you select a program that aligns with your interests and your career goals. The flexibility of online study may help your doctoral program seem less burdensome. In addition, capstone projects are sometimes easier than writing dissertations.

If earning a doctoral degree in a short time frame is important to you, then consider the many potential benefits that online programs have to offer. Within just a few years, you may be able to place the letters “PhD” at the end of your name.

How long does it take to get a phd.

On average, it takes 4-5 years to complete a Doctor of Philosophy (PhD) program. In the US, most PhD programs are between 4-6 years, while in Canada they are typically shorter, around 3-4 years.

Some students take longer than 6 years to complete their PhD, but in general the longest time it takes to get a PhD is capped at 8 years. If you’re enrolling in a part-time PhD program, for instance, your timeline will probably be extended to 6-8 years.

The shortest PhD programs out there are accelerated or sometimes online PhD programs. Some of these are only 1-2 years long, but there are comparatively fewer programs available, and they are only suitable for certain fields and careers which require less intensive research which defines most PhD programs.

One of the main reasons why it takes many years to get a PhD is because these programs are comprehensive and the requirements to graduate are extensive. Most have a set number of credit hours you need to complete, examinations to write, plus you’ll need to write your PhD thesis or dissertation, unless you pursue a PhD without dissertation .

There are certainly ways to shorten the PhD application timeline and time to graduate, which includes enrolling in a shorter program if possible, increasing your course load or the number of research hours you can dedicate per week, but generally a PhD will still take some time.

Even if you want to do a PhD without a master’s degree first, such as by applying to a direct entry PhD program, the program is still usually 4-5 years long.

We’ll take a look at the typical PhD timeline and how long it takes to get a PhD normally. After, we’ll cover some tips on how to get your PhD done faster or how you can avoid dragging things out.

In North America, the typical PhD program is divided into two stages. The first stage is where you complete all the required coursework, comprehensive exams and other academic requirements, depending on the program. The second stage is when you submit a proposal for original, independent research, get it approved and start working on your thesis or dissertation. Your PhD culminates with your thesis defense. Once your thesis has been approved, you’ll be eligible to graduate.

This timeline is somewhat flexible, as you might complete the first stage in 1 or 2 years but take longer to complete your dissertation. For the purpose of this general PhD schedule, we’ll assume your PhD program is a typical length of 4-6 years.

Application Stage

We’ve included the application stage of getting your PhD here first because the grad school application timeline can take several months to put together your application package and hear back about acceptance to a program. Secondly, because the application stage involves some critical steps you’ll need to complete in order to get your PhD.

1. Research proposal

To apply to a PhD program, you’ll most likely be required to submit a research proposal and be prepared to answer any research proposal questions your advisor will have. This is your “proposal” of what research question you will explore during your studies at a program, or an outline of what research topic you want to pursue. If you’re not sure how to write a research proposal, check out these Oxford PhD proposal samples or a Cambridge PhD proposal sample.

2. Application materials

The admission requirements for a PhD can vary from program to program, but here are the general components of a PhD application:

• Required prerequisite coursework
• Official transcripts (and minimum GPA)
• Graduate school statement of purpose
• CV for graduate school or research resume
• PhD motivation letter

Some programs may also ask you to submit additional essays, such as a letter of intent, research interest statement or grad school career goals statement .

Many PhD programs also invite you to a grad school interview to get to know you better. Be ready for common graduate school interview questions such as “ tell me about yourself ” and “ why do you want to do a PhD ?”

PhD Years 1-3: Coursework Stage

1. orientation.

Your PhD program will usually begin with your orientation, where you’ll learn about the program’s individual structure, requirements and expectations. You’ll also either choose or be assigned an academic advisor and schedule an initial meeting with them. Your advisor will be a member of the university faculty who will act as your support while you complete your research and write your thesis.

2. Coursework

The first year or two of your PhD will involve completing required advanced coursework in your field. You’ll attend lectures and seminars and you may participate in research projects with department faculty or fellow graduate students or even lab work, depending on your field.

3. Electives

Along with required coursework, you’ll have the chance to take elective courses that interest you or relate to your field. It’s important to choose electives that will enrich your program. Choose ones that really interest you, that might help inform your PhD research or that will help you fulfill your credit requirements.

4. Extracurriculars

PhD programs sometimes have extracurricular activities or additional requirements outside the classroom. This can include internships or a practicum you need to complete for credit, or you might be interested in attending academic conferences or relevant events to socialize and network you’re your colleagues in the field.

5. Comprehensive exams

The coursework stage of your PhD program will end with comprehensive exams , sometimes called qualifying or preliminary exams. These are your “final exams” to make sure that you completed the necessary PhD coursework and that you’re ready and qualified to take on your own independent research in the next phase.

1. Thesis proposal

You may recall that you submitted a research proposal as part of your PhD application, and this step of the process is similar. Your thesis proposal is just like your research proposal, but it’s a more refined and developed version. Throughout your coursework, your research question might have changed or you might have changed course a little bit. If you’re still thinking about your PhD topic , take the time to solidify it before you reach the thesis proposal stage.

Your research proposal might have been a first draft, while your thesis proposal is your official announcement of: this is what I propose to research in this PhD program.

Depending on your field and the program, you thesis research might involve a great deal of lab work, or data collection or fieldwork. Whatever the case, your thesis proposal is a complete outline of what you intend to do for this independent research project and the steps you’ll take.

2. Thesis approval

Once your proposal is written, you’ll submit it for approval. Your academic advisor, PhD supervisor or the PhD committee overseeing your program will review it and either approve it or make suggestions for changes. Once it’s been polished and finalized, you’ll be given the go ahead to start conducting your research.

3. PhD research

Your research alone will probably take you several semesters to complete. On top of the fieldwork, lab work or data collection and analysis you’ll be completing, you’ll be using this time to write and review. Writing your thesis or dissertation takes a fair number of hours to outline, draft, edit and complete. It also means hitting the books to complete a literature review of your research topic so you have a complete background understanding of your chosen topic and how it will inform your research.

Your research and the preparation of your thesis is really the biggest part of this second stage, and is probably the longest part of your PhD altogether.

4. Extra requirements

When you’re not deep in your research, you’ll be completing other requirements of your PhD program or additional duties that enrich your education. Some programs require you to dedicate some hours to teaching, whether it be leading seminars for undergraduate students or acting as a teaching assistant for university faculty.

You’ll also be strongly encouraged to publish as a graduate student , so you may be involved in the research projects of faculty members or other grad students when you’re not working on your dissertation.

5. Thesis submission and preparation for thesis defense

When you’re finished writing your thesis and you’re ready to submit it, it’s critical to know how to prepare for thesis defense . Because not only do you have to complete this original, new body of research work, you have to get the approval of your PhD committee to put it out into the world.

Your thesis defense is essentially the final presentation of your PhD.

6. Thesis defense

Your thesis defense is an oral presentation of your research project, but it also involves submitting your written document to be reviewed. Essentially, you’ll present the entirety of your thesis to the PhD supervising committee, including your findings and conclusions. From there, the committee will ask thesis defense questions . Your answers will defend your methodology and results to the committee, basically proving the value and validity of your work. While this is an evaluation of sorts, it is also your opportunity to share your original ideas and invite further research into your topic.

After your defense, the PhD committee will either approve your thesis or send it back to you with edits or changes to be made before it can be formally approved.

Graduation and Postdoc

Once your thesis has been approved, congratulations! You’ll be eligible for graduation and be awarded your degree. Now that you’ve finished this marathon, you can choose to pursue further studies or start looking for a job after grad school .

With a PhD, you have many different options for positions in your field. You might want to know how to find a job in academia or how to get a tenure track position at a university if you’re interested in teaching others. PhD graduates who decide to transition from academia to industry or who would rather work outside the realm of academia can find industry jobs after PhD that suit their skills and experiences.

Either way, you’ll need to prepare for how to find a postdoc position, explore what the career options are for you, decide what your career goals are and start sending out applications. Remember to prep your postdoc resume and get read for postdoc interview questions , since the job hunt will begin soon after you finish your PhD!

Is it possible to get your PhD done faster? What are some ways you can speed up the process and avoid taking 8 years to complete your graduate studies? Luckily, there are many key ways you can make your journey through grad school easier and speed things up a little, from the type of PhD program you choose to the habits and skills you cultivate during your program.

#1 Enroll in an accelerated program

The first way to guarantee it will take less time to get your PhD is to, of course, enroll in a shorter PhD program. Direct entry PhD programs allow you to enroll once you’ve completed your bachelor’s degree in exceptional circumstances. Note that these are not the easiest PhD programs to get into , as your academic record needs to be excellent, and you’ll likely need prior research experience and you may even need to have publications already. However, a direct entry PhD program is around 4-5 years, but it allows you to skip the 1-2 years it would take to earn a master’s degree.

You can also choose to enroll in an online or accelerated PhD program that is designed to be much shorter than the traditional PhD. Once again, though, these programs are not available to students in every field, so you may need to research whether there are any options for you.

#2 Choose the right mentor

One of the first things you can do to ensure your PhD is smooth sailing is to choose the right mentor or academic advisor. Many programs allow you to choose your advisor, while some assign one to you. Whatever the case, it’s important to establish a strong working relationship and clear expectations early on.

One of the first things you’ll do as a PhD student is meet with your advisor. Take the time to discuss with them what your expectations for the program are, ask questions and ask them what their expectations are of you. Your advisor is there to help you and advise you, and they have resources and connections you can use to your advantage. But they are also working with a busy schedule and might be advising more than one PhD student, too. A mutually respectful relationship with open communication will ensure fewer interpersonal hurdles down the road.

#3 Earn credit hours faster

One way you can shave some time off your PhD is by earning your credit hours faster and getting to the research and thesis-writing stage faster. This might mean you take on a full-time course load or ask your advisor for ways to earn extra credit, such as participating in research projects. Some PhD programs will give you course credit for previous graduate level coursework you might have completed during your master’s degree, or for certifications and professional education you completed outside of school.

#4 Keep your thesis focused

When you get started on your research, it’s easy to feel overwhelmed with the amount of work you need to complete, with the writing of your thesis on top of it all. One way to keep your research hyper-focused and on point is to keep your thesis topic narrow. If your subject is too broad, you’ll be spending way too much time in your research. Give yourself clear objectives and scope, and don’t deviate from your PhD proposal if you don’t have to.

There may be a million questions you want to explore within your PhD topic, but there will be other opportunities to explore them. Keep your focus narrow so you don’t spend years and years asking and answering research questions!

One of the best things you can do to get your PhD done faster and adjust to the experience of graduate school is to change your thinking. Adopt a growth mindset so that you’re open to new learning, willing to listen to constructive feedback on your proposal or thesis and willing to grow your skills. A PhD is an advanced program, and you’ll already be very skilled, but it is also an opportunity to learn and grow. There will be challenges for you, so be ready to meet and overcome them instead of letting them draw you back or slow you down.

#5 Develop your professional skills fast

A PhD is an opportunity to grow your professional skillset as much as it is an opportunity for you to contribute meaningfully to your field. If you haven’t already been working on skills such as communication, presenting or lecturing and writing, now is the time to start.

Strong writing skills will help you get your thesis finished and edited faster, as you’ll be more familiar with the process and understand what makes a strong document. It’s also a useful skill to learn how to write effective funding proposals or grant proposals. You may need to do so to secure funding for your research, but it’s a highly valuable skill in the workforce, too.

Good presentation skills will help you during your thesis defense or if you’re asked to present during a conference. They will also help you build confidence in your voice and ideas and make you a better communicator when you’re networking or job searching.

#6 Keep to your schedule

This is maybe the most important skill if you want to finish your PhD faster: make a detailed schedule and hold yourself accountable to it. If you like, you can plan out your entire PhD week by week from Day 1. Write down what your course schedule is, when you’ll do research and how many hours, when you’ll write and how many hours, what extracurriculars or personal activities will take up your time and so on.

A detailed schedule gives you an overview of your PhD and a timeline of when you’ll finish. It will keep you organized and accountable, so you can avoid procrastinating or avoidable speed bumps that might slow you down. It also helps you compartmentalize the many items on your to-do list so you don’t stress out about how much you need to accomplish.

When creating your schedule, especially during the research stage when there is no formal class schedule for you to adhere to, focus on deliverables. Set a date when you will submit a section of your thesis to your advisor, or when you will complete your literature review. Setting goals and clear outcomes will keep you on track and focused.

#7 Take initiative and be independent

The last tip to help you get your PhD done faster is to take initiative. Remember that a PhD is a largely independent endeavor. You’ll have the support of a committee or advisor, but you can’t rely on them to do the work for you or put everything on hold if they aren’t available when you need them. Be flexible and adaptable so you can keep working and moving forward, even if your schedule gets interrupted or needs to change to suit your situation.

It's also important to take the initiative in your learning. Take advantage of opportunities for growth, networking, and gaining experience where you can. Get the most out of your PhD program and use your experiences to fuel your end goal of completing your thesis.

On average, it takes 4-5 years to get a PhD. There are a few factors that can influence the time it takes to complete your PhD, from program length and structure to what country you are earning your PhD in, to your own personal work ethic and schedule.

PhD programs in the US are on average 4-6 years. In Canada and the UK, they are usually 3-5 years long. Part-time PhD programs may take up to 7-8 years to complete. Direct-entry PhD programs and dual master’s and PhD programs are typically 5 years long. If you’re enrolling in an online, hybrid or accelerated PhD program, the timeline is usually 2-3 years, but there are some extremely short 1-year PhD programs offered online for specific disciplines.

Yes, you can finish your PhD before the “normal” timeline. For example, if you complete your coursework early, if you finish writing your thesis faster than average and get it approved, or if you otherwise complete all your PhD program requirements before the anticipated finish date. 

Yes, there are online PhDs available for certain fields and disciplines. These typically range from 2-3 years, although there are some traditional 4-year PhD programs offered online. There are also some “accelerated” online PhDs which last 12-18 months.

A PhD program is not necessarily shorter if you first complete a master’s degree, but having gone through a master’s program can better prepare you to finish your PhD faster. Some PhD programs accept credit hours from your master’s degree towards the coursework requirements for a PhD, and if you’ve previously written a master’s thesis or completed some research during your graduate studies, this will be an advantage. Since you’ll already be familiar with the process of writing a thesis and conducting your own research, you can avoid some stumbling blocks in your PhD program that might otherwise slow down your progress.

Yes, it is possible to get a PhD without first completing a master’s degree. There are direct entry PhD programs that allow students with a bachelor’s degree to enroll, so long as they meet the admission requirements and have exceptional academic records. Some online PhDs also waive the master’s degree requirement.

Yes, it is possible to complete a traditional PhD program in a shorter amount of time than anticipate. This usually means dedicating yourself to full-time study or taking on a larger course load and increased research hours. It takes significant work, but it can be done with the right schedule and commitment.

The fastest PhD programs are the short, 1-year accelerated programs. These programs have fewer credit hours to complete, and some have no dissertation requirement, only qualifying exams to finish. However, there are not many programs out there, and they are not available for every field of interest.

Introduction

Factors influencing phd duration, typical duration of phd, phd duration: variations by country, stages of a phd program, shortening the phd timeline, lengthening the timeline of phd.

A PhD, or Doctor of Philosophy, is the highest academic degree one can attain. It represents expertise in a specific field and often involves original research contributing to the world’s knowledge. However, this academic feat isn’t for the faint of heart. To embark on this journey, you should be aware of the formidable challenges it presents, and one of the most fundamental questions is, “How long will it take?” In the introduction, you can touch upon the idea of academic ambition, the pursuit of knowledge, and the unique challenges that come with obtaining a Ph.D.

It’s essential to emphasize why understanding the time commitment is crucial. Pursuing a Ph.D. isn’t just an intellectual endeavor; it’s also a significant personal and professional commitment. It can impact one’s life, career, and even mental and emotional well-being. You can mention that by knowing what you’re getting into time-wise, you can make informed decisions about your academic and career goals. For instance, if you’re aware that a Ph.D. typically takes several years, you can plan your life accordingly, set expectations, and ensure you have the necessary resources and support in place.

Imagine standing at the crossroads of ambition and dedication. You’re passionate about a particular field, and the thought of making a meaningful contribution to it excites you. You dream of becoming a respected expert, perhaps even shaping the future of your discipline. This ambition has led you to consider pursuing a PhD, a journey that represents the highest echelon of academic achievement.

But before you dive into the world of research, scholarly papers, and intellectual debates, there’s a critical question that looms large—how long will it take to earn that coveted Doctor of Philosophy degree? The answer isn’t as straightforward as one might hope. It’s a complex equation, influenced by various factors, and it’s a puzzle that many aspiring doctoral students grapple with.

Understanding the time commitment of a PhD is not merely a matter of academic curiosity. It’s a pivotal factor that can shape your life’s trajectory in significant ways. This introduction explores the intricacies of a PhD journey, from the initial spark of academic passion to the profound understanding of what it takes, in terms of time, to turn that passion into a doctoral reality.

Earning a PhD is a highly individualized journey, and its duration can vary significantly from person to person. This section will delve into the myriad factors that play a role in determining the length of a PhD program. It’s important to understand that the timeline is not a fixed number of years but is influenced by various variables. Here are some key factors:

• Field of Study: The nature of your research area has a significant impact. Some fields, such as the natural sciences or engineering, might require extensive laboratory work and data collection, which can lengthen the Ph.D. process. In contrast, fields like humanities or social sciences might involve less time-intensive data collection but demand extensive writing and analysis.
• Country: The country in which you pursue your PhD can greatly affect the duration. Different countries have different academic systems and expectations. For example, in the United States, it’s common for PhD programs to last longer compared to some European countries where they tend to be shorter and more structured.
• Research Focus: The specific focus of your research project can influence the time required. If your research involves cutting-edge, complex topics, it might take longer to gather and analyze data or develop new methodologies. On the other hand, a well-defined and less ambitious research question could lead to a quicker completion.

Let’s take a closer look at the intricate web of factors that influence the duration of a PhD program. Imagine two students, both embarking on their journeys to earn a PhD, but in different fields.

Student A is pursuing a PhD in physics. This field often involves conducting elaborate experiments, gathering extensive data, and fine-tuning intricate instruments. The pursuit of new discoveries in the realm of physics can be time-consuming, and the PhD program might extend to several years to complete all the necessary research.

Student B, on the other hand, is studying literature and cultural studies. Their research involves in-depth analysis of existing texts, interpretations, and critical theories. While the reading and writing process is extensive, it may not require as many years as Student A’s experimental work.

Now, consider these students in the context of the country in which they are pursuing their PhD Student A is in the United States, where doctoral programs typically span several years. Meanwhile, Student B is in a European country known for its structured and shorter Ph.D. programs.

Lastly, let’s factor in research focus. Student A’s project is ambitious, attempting to uncover the mysteries of the universe, which can be a time-intensive endeavor. In contrast, Student B’s research question is more narrowly defined, making the path to completion relatively shorter.

These examples illustrate how the combination of field of study, country, and research focus can significantly influence the duration of a PhD program.

Understanding the average duration of a PhD program can help prospective students set realistic expectations. This section will provide an overview of the typical timeframes for completing a PhD.

• Average Duration: On a global scale, a PhD program often spans between 5 to 7 years. This period includes coursework, research, and the writing and defense of a dissertation. However, it’s important to note that this duration can vary significantly. In the United States , for instance, it’s common for PhD programs to take longer, often 5 to 7 years or even more, due to the inclusion of coursework and comprehensive exams. In contrast, in some European countries, PhD programs are designed to be shorter, typically around 3 to 4 years, as they are research-focused with less emphasis on coursework.
• Variations by Field: The average duration can also differ based on the field of study. Fields requiring extensive data collection, such as the natural sciences or engineering, might take longer, while fields like humanities or social sciences with more writing and analysis may have shorter timeframes.

When it comes to the average duration of a PhD program, the common adage ‘it’s a marathon, not a sprint’ certainly applies. The typical journey to a PhD is a long and demanding one, taking aspiring scholars through a series of rigorous academic challenges.

Globally, a PhD program often spans between 5 to 7 years. This period includes the initial coursework phase, where students delve deep into the theoretical foundations of their field. This is followed by a substantial research phase, during which they gather data, conduct experiments, or engage in extensive fieldwork. Finally, the culmination of this journey is the completion and defense of a dissertation, a written document that contributes new knowledge to their field.

However, it’s crucial to remember that these timeframes are general averages and can vary significantly based on various factors. In the United States, for example, it’s quite common for PhD programs to extend to the longer end of the spectrum, taking 5 to 7 years or even more to complete. This is because American PhD programs often include a significant coursework component and comprehensive exams before the dissertation phase begins.

On the other hand, in some European countries, PhD programs are designed to be more streamlined and research-focused. They typically take around 3 to 4 years to complete, reflecting a shorter timeframe. This structure is influenced by the belief that students entering PhD programs are already well-prepared in their chosen field, and the primary focus is on conducting independent research.

Additionally, the duration can also vary based on the specific field of study. Fields that require extensive data collection or experimental work, such as the natural sciences or engineering, tend to have longer PhD programs. In contrast, fields like humanities or social sciences, where research involves more reading, writing, and analysis, may have shorter timeframes.

Keep in mind that these are general guidelines, and individual PhD experiences can deviate from the average.

Ph.D. program durations can vary significantly between countries due to differences in educational systems and academic traditions. This section will explore how and why PhD programs’ lengths differ by country.

• United States: In the United States, PhD programs are known for their comprehensive structure. They often include a combination of coursework, comprehensive exams, and dissertation research. This makes them typically longer, often spanning 5 to 7 years or more.
• European Countries: In many European countries, PhD programs are more streamlined and research-focused. They tend to be shorter, typically around 3 to 4 years. European programs often assume that students have a strong foundation in their field when they enter the Ph.D. phase.
• Other Countries: The duration of PhD programs can also vary in other parts of the world. For instance, in some Asian countries, the length of a PhD program can be influenced by the nature of the research and the institution’s specific requirements.

When contemplating the pursuit of a Ph.D., it’s important to recognize that the path you tread can be markedly different depending on the country in which you choose to study. The world’s countries have diverse academic systems and traditions, and these intricacies play a significant role in shaping the duration of PhD programs.

Consider the United States, a country renowned for its rigorous academic programs. Here, PhD programs are known for their comprehensive nature. Students often undergo a period of intensive coursework, followed by comprehensive exams to assess their knowledge. This is in addition to the research phase, which involves conducting experiments, gathering data, or delving deep into the chosen area of study. As a result, PhD programs in the United States are often among the longer ones, frequently taking 5 to 7 years or even more to complete.

In contrast, many European countries have adopted a more streamlined approach to PhD programs. These programs tend to be research-focused from the outset, with the assumption that students entering PhD programs already possess a strong foundation in their chosen field. The result is a shorter program, typically spanning around 3 to 4 years. In countries like the United Kingdom, the Netherlands, and Denmark, students can transition directly into their research, which contributes to the shorter duration.

Outside of the United States and Europe, PhD program lengths can vary significantly depending on the country’s educational system and specific institutional requirements. For instance, in certain Asian countries, PhD programs might also be research-intensive and shorter in duration, or they might extend to accommodate the complexity of the research involved.

It’s important to understand these country-specific variations when considering a PhD program, as they can have a profound impact on the length of your academic journey.

A Ph.D. program is not a single, continuous journey but is typically divided into distinct stages. This section will provide an overview of the common stages of a PhD program, which include coursework, research, and dissertation writing.

• Coursework: The journey usually starts with a coursework phase, where students dive deep into the theoretical foundations of their field. During this stage, students take classes and seminars to build a strong academic foundation. The duration of this stage varies by country and field but generally lasts from 1 to 2 years.
• Comprehensive Exams: In some countries, notably the United States, students are required to pass comprehensive exams to demonstrate their mastery of their field. This stage can add a few months to a couple of years to the timeline.
• Research Phase: After coursework and exams, students transition into the research phase, which is the heart of a Ph.D. program. This phase involves conducting original research, experiments, fieldwork, or in-depth analysis, depending on the field of study. It can last several years, usually 3 to 5 years or more, depending on the complexity of the research and the progress made.
• Dissertation Writing: The final stage involves writing the PhD dissertation, a comprehensive document that presents the research findings and contributes to the academic field. The duration of this stage varies but often takes at least a year.

A PhD program is akin to an academic epic, with distinct stages that collectively make up the hero’s journey. As an aspiring doctoral candidate, it’s essential to understand the key stages you’ll encounter along the way.

The odyssey begins with coursework. During this initial stage, students embark on a voyage into the theoretical underpinnings of their chosen field. They attend classes, seminars, and lectures to deepen their understanding. This coursework phase, which can last anywhere from 1 to 2 years, serves as the foundation upon which the rest of the journey is built.

In some countries, particularly the United States, there’s another formidable challenge—comprehensive exams. These exams test the student’s mastery of the field’s core concepts and are often required before moving on to the next stage. Comprehensive exams can extend the journey by several months to a couple of years.

The heart of the PhD journey lies in the research phase. This is where students immerse themselves in original research, which could entail conducting experiments, gathering data, or engaging in extensive fieldwork, depending on their field of study. The duration of this stage is the most variable, spanning approximately 3 to 5 years or even longer, depending on the complexity of the research and the progress made.

Lastly, the culmination of the PhD adventure is the dissertation writing stage. Here, students craft a comprehensive document that presents their research findings, methodology, and contributions to the academic field. This final stage can vary in length but often takes at least a year to complete.

These stages collectively shape the journey towards a PhD, and understanding them is vital for anyone embarking on this academic odyssey.

While earning a Ph.D. is a significant commitment, there are strategies to expedite the process. This section will discuss strategies and approaches that can help shorten the timeline of your PhD journey .

• Efficient Time Management: Effective time management is essential for expediting a PhD program. Planning and prioritizing tasks, setting clear goals, and maintaining a structured schedule can help students make the most of their research and coursework, reducing the time spent on unnecessary or unproductive activities.
• Choosing the Right Advisor: The relationship between a Ph.D. student and their advisor can significantly impact the program’s duration. A supportive and experienced advisor can guide the student effectively, provide valuable insights, and help them navigate research challenges more efficiently. A strong advisor-student relationship can lead to better research progress and a quicker completion.
• Prior Research Experience: Entering a PhD program with prior research experience can be a significant advantage. If you’ve already conducted research related to your PhD topic during a master’s program or as an undergraduate, you may be able to accelerate your research and data collection, potentially shortening the overall timeline.

When it comes to earning a PhD, the duration can be an intimidating factor. However, it’s important to remember that there are strategies that can help expedite the journey. Let’s explore some of these approaches:

One of the most fundamental strategies is efficient time management. Effective planning, prioritization, and maintaining a structured schedule can make a world of difference. By setting clear goals and staying organized, students can optimize their time and reduce the risk of distractions or time wasted on non-essential activities. This approach ensures that every moment spent on research or coursework is meaningful and productive.

Another pivotal factor is the choice of an advisor. The advisor-student relationship plays a crucial role in a Ph.D. program. A supportive, experienced, and engaged advisor can guide a student through the research process more effectively. They can offer valuable insights, help troubleshoot research challenges, and provide a sense of direction. With the right advisor, students often find themselves making more efficient progress and thus shortening the overall timeline of their PhD journey.

For those entering a PhD program with prior research experience, there’s an advantage. If you’ve already dabbled in research during your master’s program or as an undergraduate, you’re poised for a quicker start. The knowledge, skills, and methodologies you’ve acquired can significantly expedite your research and data collection, potentially helping you complete your PhD in less time.

These strategies, when applied thoughtfully, can make the road to a PhD a bit smoother and shorter, ultimately allowing students to achieve their academic goals more efficiently.

While shortening the Ph.D. journey is a common goal, there are situations that can unexpectedly lengthen the timeline. This section will discuss various reasons a Ph.D. might take longer than expected, including research challenges and personal circumstances.

• Complex Research Challenges: Research is at the core of a Ph.D., and sometimes, research challenges can extend the timeline. For instance, unexpected technical issues, data collection difficulties, or unanticipated roadblocks in the research process can delay progress. Dealing with these complexities often requires additional time and problem-solving efforts.
• Scope of the Project: Sometimes, students may underestimate the scope of their research project. If the research topic turns out to be more extensive or multifaceted than initially anticipated, it can lead to a longer journey. Expanding the research scope can also be driven by a desire to make a more substantial contribution to the field.
• Personal Circumstances: Personal circumstances can also play a significant role in lengthening the timeline. Life events, such as family responsibilities, health issues, or other personal challenges, can disrupt the academic trajectory and extend the Ph.D. program.

While aspiring doctoral candidates often set out with the goal of completing their PhD as efficiently as possible, it’s important to acknowledge that unexpected factors can sometimes extend the journey. Let’s delve into some of the reasons a PhD might take longer than initially expected:

One of the most common factors is research challenges. Research is the backbone of a Ph.D., and it’s not uncommon to encounter unanticipated complexities along the way. For instance, imagine a Ph.D. student in the field of environmental science who encounters technical issues with specialized equipment required for data collection. These unexpected hurdles can require additional time and effort to resolve, extending the research phase.

Another factor that can elongate the timeline is the scope of the project. Sometimes, students may begin their research with a particular understanding of the project’s scale, only to discover that the topic is more extensive or multifaceted than initially thought. This realization can lead to an expansion of the research scope, often driven by the desire to make a more significant and impactful contribution to the field. While noble in its intent, this expansion can result in a longer and more extensive research phase.

Personal circumstances can also have a profound impact. Life doesn’t always adhere to the academic calendar, and various personal challenges can disrupt the PhD journey. These challenges can include family responsibilities, health issues, or other unforeseen life events. Balancing these personal circumstances with academic commitments can sometimes lead to a longer timeline for completing a PhD.

It’s crucial to recognize that while we often have our sights set on a timely completion, the PhD journey can be influenced by a myriad of unforeseen factors. Overcoming these challenges is a testament to resilience and dedication in the pursuit of knowledge.

Frequently asked questions

How long does it take to get a phd.

This varies by country. In the United States, PhDs usually take between 5–7 years: 2 years of coursework followed by 3–5 years of independent research work to produce a dissertation.

In the rest of the world, students normally have a master’s degree before beginning the PhD, so they proceed directly to the research stage and complete a PhD in 3–5 years.

Frequently asked questions: Graduate school

In the US, most graduate school applications require you to include:

• Transcripts from previous educational institutions
• Standardized test scores (such as the GRE or MCAT)
• A graduate resume
• 2–3 letters of recommendation
• A statement of purpose

Some programs may ask you to write a personal statement in addition to, or instead of, a statement of purpose. You may also be asked to an interview .

Always carefully read the application instructions for the specific program you’re applying to.

Most medical school programs interview candidates, as do many (though not all) leading law and business schools.

In research programs, it depends—PhDs in business usually do, while those in economics normally do not, for example.

Some schools interview everyone, while others only interview their top candidates. Look at the websites of the schools you’re applying to for more information on whether they conduct interviews.

In addition to thinking about your answers for the most commonly asked grad school interview questions , you should reach out to former and current students to ask their advice on preparing and what sort of questions will be asked.

Look back through your resume and come up with anecdotes that you could use for common questions, particularly those that ask about obstacles that you overcame. If you’re applying for a research program, ensure that you can talk about the previous research experience you’ve had.

You should also read as much research in your field as possible. Research the faculty at the schools you’re applying to and read some of their papers. Come up with a few questions that you could ask them.

Graduate schools often ask questions about why you are interested in this particular program and what you will contribute.

Try to stay away from cliche answers like “this is a good program” or “I got good grades in undergrad” and focus instead on the unique strengths of the program or what you will bring to the table. Understand what the program is looking for and come up with anecdotes that demonstrate why you are a good fit for them.

Different types of programs may also focus on different questions:

• Research programs will often ask what topics you’d like to research and who you would like to work with, as well as specific questions about your research background.
• Medical schools are interested in your personal motivation, qualities such as integrity and empathy, and how you’d respond to common ethical dilemmas.
• Business schools will focus on your past work experience and future career prospects, and may be particularly interested in any experience you have managing or working with others.

Some students apply to graduate school straight from undergrad, but it’s also common to go back to school later in life. The ideal time to do so depends on various financial, personal, and career considerations . Graduate school is a big commitment, so you should apply at a time when you can devote your full attention to it.

Your career path may also determine when you should apply. In some career fields, you can easily progress without a graduate degree, while in others—such as medicine, business, and law—it’s virtually impossible to move up the career ladder without a specific graduate degree.

Most graduate school applications for American graduate programs are due in December or January for a September start.

Some types of programs, especially law school, are rolling applications, meaning that the earlier you apply, the earlier you’ll hear back. In this case, you should aim to apply as early as possible to maximize your chances.

Medical school follows a completely separate timeline with much earlier deadlines. If you’re applying for medical school, you should speak to advisors at your university for more information.

A good starting point to aim for is about 18 months before you would start the program, or 6–9 months before the applications are due.

In the first few months of the process, research programs and study for any standardized exams you might need.

You can then begin writing your personal statements and statements of purpose , as well as contacting people to write your letters of recommendation . Ensure that you give recommenders plenty of time to complete their letters (ideally around 2–4 months).

In the US, the graduate school application process is similar whether you’re applying for a master’s or a PhD . Both require letters of recommendation , a statement of purpose or personal statement , a resume or CV , and transcripts. Programs in the US and Canada usually also require a certain type of standardized test—often the GRE.

Outside the US, PhD programs usually also require applicants to write a research proposal , because students are expected to begin dissertation research in the first year of their PhD.

A master’s degree usually has a higher upfront cost, but it also allows you to start earning a higher salary more quickly. The exact cost depends on the country and the school: private universities usually cost more than public ones, and European degrees usually cost less than North American ones. There are limited possibilities for financial aid.

PhDs often waive tuition fees and offer a living stipend in exchange for a teaching or research assistantship. However, they take many years to complete, during which time you earn very little.

This depends on the country. In the United States, you can generally go directly to a PhD  with only a bachelor’s degree, as a master’s program is included as part of the doctoral program.

Elsewhere, you generally need to graduate from a research-intensive master’s degree before continuing to the PhD.

A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.

A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.

A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.

All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.

It’s best to ask in person if possible, so first reach out and request a meeting to discuss your graduate school plans.

Let the potential recommender know which programs you’re applying to, and ask if they feel they can provide a strong letter of recommendation . A lukewarm recommendation can be the kiss of death for an application, so make sure your letter writers are enthusiastic about recommending you and your work!

Always remember to remain polite. Your recommenders are doing you a favor by taking the time to write a letter in support of your graduate school goals.

This depends on the program that you are applying for. Generally, for professional programs like business and policy school, you should ask managers who can speak to your future leadership potential and ability to succeed in your chosen career path.

However, in other graduate programs, you should mostly ask your former professors or research supervisors to write your recommendation letters , unless you have worked in a job that corresponds closely with your chosen field (e.g., as a full-time research assistant).

Choose people who know your work well and can speak to your ability to succeed in the program that you are applying to.

Remember, it is far more important to choose someone who knows you well than someone well-known. You may have taken classes with more prominent professors, but if they haven’t worked closely with you, they probably can’t write you a strong letter.

The sections in your graduate school resume depend on two things: your experience, and the focus of the program you’re applying to.

Always start with your education. If you have more than one degree, list the most recent one first.

The title and order of the other sections depend on what you want to emphasize. You might include things like:

• Professional experience
• Voluntary and extracurricular activities
• Publications
• Awards and honors
• Skills and certifications

The resume should aim for a balance between two things: giving a snapshot of what you’ve done with your life so far, and showing that you’re a good candidate for graduate study.

A resume is typically shorter than a CV, giving only the most relevant professional and educational highlights.

An academic CV should give full details of your education and career, including lists of publications and presentations, certifications, memberships, grants, and research projects. Because it is more comprehensive, it’s acceptable for an academic CV to be many pages long.

Note that, outside of the US, resume and CV are often used interchangeably.

No, don’t include your high school courses and grades. The education section should only detail your college education.

If you want to discuss aspects of high school in your graduate school application, you can include this in your personal statement .

A resume for a graduate school application is typically no more than 1–2 pages long.

Note, however, that if you are asked to submit a CV (curriculum vitae), you should give comprehensive details of all your academic experience. An academic CV can be much longer than a normal resume.

Always carefully check the instructions and adhere to any length requirements for each application.

If you’re applying to multiple graduate school programs, you should tailor your personal statement to each application.

Some applications provide a prompt or question. In this case, you might have to write a new personal statement from scratch: the most important task is to respond to what you have been asked.

If there’s no prompt or guidelines, you can re-use the same idea for your personal statement – but change the details wherever relevant, making sure to emphasize why you’re applying to this specific program.

If the application also includes other essays, such as a statement of purpose , you might have to revise your personal statement to avoid repeating the same information.

The typical length of a personal statement for graduate school applications is between 500 and 1,000 words.

Different programs have different requirements, so always check if there’s a minimum or maximum length and stick to the guidelines. If there is no recommended word count, aim for no more than 1-2 pages.

A statement of purpose is usually more formal, focusing on your academic or professional goals. It shouldn’t include anything that isn’t directly relevant to the application.

A personal statement can often be more creative. It might tell a story that isn’t directly related to the application, but that shows something about your personality, values, and motivations.

However, both types of document have the same overall goal: to demonstrate your potential as a graduate student and s how why you’re a great match for the program.

PhD duration in the USA

I am trying to find out what the average duration of PhD studies are in the USA. Here in Spain it used to be 4 years, but it seems that Europe is moving towards a 3-year scheme since students are expected to do their MSc before they start. What is it like in the USA? Is some kind of shortening also occurring?

• 6 Keep in mind that, in many fields, the time to PhD in the US also includes the coursework (master's) component, so the research phase can be anywhere from one semester to almost two years shorter than the "time to PhD." –  aeismail Commented Mar 24, 2014 at 17:02
• 4 In the experimental sciences, the time it takes to get a PhD can depend heavily on how a particular experiment or program of research works out. In physics it's not uncommon for people to do their coursework, then take several years trying to get an experiment to work, then give up and start over with some other experiment, which takes several more years. At the school where I got my PhD in physics, I think about 30% of my peers took 9 years total. –  user1482 Commented Mar 25, 2014 at 0:29
• 2 The dean of social sciences at my school is an archaeologist and mentioned offhand that his students typically take 9+ years to finish due to fieldwork. –  Tim Commented Aug 7, 2014 at 8:42
• 2 "it seems that Europe is moving towards a 3-year scheme" - I am not sure this applies so generally. In Germany, there is a certain movement towards structured doctoral programs, but newly introduced programs are quite sometimes designed to take four years. Moreover, the practical way these are sometimes conducted is that the doctoral candidate goes through the structured doctoral program for four years, and then remains with his or her department for another year or so, funded from other sources, to complete their doctoral thesis, thus maintaining the original duration of roughly five year –  O.

Each program is going to be different. Usually, the first couple years of a PhD program involves taking graduate level classes while the later years are dedicated to academic engagement in the discipline (for example, in Chemistry, you would do research in a lab.) If you have a Masters degree relevant to the PhD, you may cut off some or all of the classroom portion of the PhD program.

The qualifications for actually receiving the PhD also differ. You may need to get approval from an academic board (this is usually at least part of the process in any case), you may need to write a thesis, you may even be required to be published in an academic journal. (In the hard sciences, this is common.)

Because the requirements for getting the degree differ, the time may as well. For the most part, PhDs (with no Masters) should take between 4 - 6 years. Getting a Masters degree first may cut off about a year or so of that. While this is generally true, you will find many examples of people taking longer and I've known at least two people who graduated in less than 4 years with a PhD.

While this is an average, you'll want to get info specific to your desired University, the degree, and even the group (or academic adviser) that you choose to work for.

• 4 It also varies by discipline. Some take substantially longer than others. –  vadim123 Commented Mar 24, 2014 at 16:32
• For US PhD recipients in 2018, the median years between starting graduate school and earning a doctorate was 7.3. Do not rely on the 4-6 years. –  Anonymous Physicist Commented Jul 18, 2020 at 2:21

This varies so widely by discipline that asking for an average across all disciplines is unlikely to be very helpful. Most individual disciplines do keep careful records of this statistic, and it should be easy to search for them on (e.g.) google.

However, I would say with some confidence that no American PhD program requires or even expects its students to complete a PhD in less than four years. In some programs the "party line" is that it is desirable to complete the degree in four years, but in my experience this means that you start to feel the squeeze of increased teaching and/or decreased funding after four years, not that you get ejected from the program or forced to graduate.

I work in a discipline, mathematics, with a high entry cost but for which, once you acquire the necessary background and skills (with which a small minority of students do enter the program), there is no specific reason why you couldn't do all the work for a great thesis and write it up in a rather short amount of time, say on the order of a semester. Nevertheless I have met very few people who have completed a math PhD in fewer than four years. When we get to the upper echelons of talent, preparation and work ethic, this surely must mean that the culture of a PhD program strongly encourages students to stay for this amount of time.

To answer your final question: yes, many programs are trying to shorten their average time to degree as funding is being cut. In my own PhD program (mathematics at UGA) I was involved in an initiative to do just this: up until recently we guaranteed six years of funding to incoming PhD students without master's degrees and five for students with an incoming master's. We now guarantee five years to all students. Note that this does not mean that we do not have funded sixth year students: we certainly do. But it means that students will, throughout their time in the program, have to keep their eye on the five-year mark, which is something that our former arrangement was not doing: even very strong students would often stick around for six years for no especially good reason.

Finally let me also note that we changed (with my involvement) all our requirements to be independent of whether students arrive with master's degrees. We have found that the difference in the level of preparedness of such students is not significant enough to justify more stringent time-to-degree requirements.

• Many thanks. I find it amazing that you fund people equally regardless of whether they have a masters's; it's very generous. Very informative answer. –  CesarGon Commented Mar 24, 2014 at 21:59
• 1 I would +1 except for the 4-year hard minimum. I know several people who did the PhD in three, in STEM fields. If you're not looking for an academic job afterward, and you know what you want to research, 3 years is realistic in many fields. –  David Ketcheson Commented Mar 25, 2014 at 3:41
• @David: There are people who got their PhDs at 20 years old; one presumes they spent a short amount of time in the program. When I say four years is a "hard minimum", I mean I know of no program in the US which requires or even expects (e.g. by decreasing funding) its students to complete a PhD in fewer than four years. Do you? –  Pete L. Clark Commented Mar 25, 2014 at 8:10
• @CesarGon: In mathematics most students don't get a master's on the way to a PhD. –  Mark Meckes Commented Mar 25, 2014 at 10:14
• @PeteL.Clark I don't know of any such program. But expectations and hard minimums are very different, in my mind. Anyway, <4 is certainly unusual. –  David Ketcheson Commented Mar 26, 2014 at 13:03

How long is a PhD program? That might be one of the first questions you ask yourself If you are thinking of earning a PhD. You have probably heard a range of years, and that is because how long it takes to earn a PhD depends on a number of factors. Keep reading to learn more!! 

What is a PhD? 

PhD stands for a “Doctorate of Philosophy.” This is an academic degree that qualifies the degree holder to teach their chosen subject at university level or to work in a specialized position in their chosen field. In general, the PhD is the highest level of degree a student can achieve. 

Also see: Top fully funded PhD programs

Why get a PhD? 

A PhD is a serious commitment with a serious return on investment. Here is a list of professional and personal benefits for earning a PhD. 

How long does it take to earn a PhD? 

Earning a PhD usually takes between four and seven years to complete, depending on the type of PhD as well as the schools requirements, the students educational background, and personal progress. Students who take full-time classes can typically finish in four years. A typical PhD program requires anywhere from 60 to 120 semester credit hours . 

Why earning a PhD takes years to earn

Assistantship obligations.

Teaching and research assistantships can be very beneficial for the experience they provide and the potential funding, but they can also be time consuming obligations for PhD students. Therefore, assistantships may affect the amount of time it takes to complete a PhD program. 

Comprehensive examinations

Universities often require students to demonstrate their readiness in a PhD program through comprehensive exams. These comprehensive exams may be known as: 

• Preliminary examinations
• Major field examinations
• Comprehensive exams or “Comps”
• General examinations

Dissertation

A dissertation is an in-depth research document that serves as the culmination of a doctoral program. It is an important document that demonstrates a student’s original research and contribution to their field of study. 

The dissertation involves conducting extensive research, reviewing previous literature, analyzing data, and presenting your findings in a structured manner. Once the dissertation is completed, it is typically defended orally in front of a committee of faculty members who assess the quality and validity of the research. 

Average PhD timeline

The specific of a PhD timeline carried by college and university. However, the following is a good overview of the average PhD program. 

• Year 1: Take advanced courses
• Year 2: Take advanced courses and begin preparing for exams
• Year 3: Study, take and defend your comprehensive exams and begin researching your dissertation proposal
• Year 4: Begin working on your dissertation
• Year 5: Finish and defend your dissertation 

Average PhD completion by focus

According to data from the National Center for Science and Engineering Statistics the average time in years from graduate school entry to doctorate it took students to receive their degree in 2020 in certain fields is listed below. 

• Life sciences = 6.9 years
• Physical sciences and earth sciences = 6.3 years
• Mathematics and computer sciences = 7.0 years
• Psychology and social sciences = 7.9 years
• Engineering = 6.8 years
• Education = 12.0 years
• Humanities and arts = 9.6 years
• Other non-S&E fields = 9.3 years

How to finish your PhD is less time

Look for accelerated classes.

Accelerated courses are an easy way to reduce the amount of time it takes to finish a PhD. Therefore, look into if your program offers any shorter courses. 

Work on your dissertation throughout the program

Working on your dissertation little by little throughout the program will allow you to speed up your doctoral timeline. In addition, it may reduce the likelihood that you’ll drop out before finishing your final project.

Maintain regular communication with your advisor

Establish regular communication with your advisor or supervisor. Regular meetings can help you receive guidance, address any issues, and ensure you are heading in the right direction.

Seek feedback early and often

Share your work and progress with your advisor, peers, or other trusted individuals often. Then, you should incorporate suggestions and revisions as you go along. This will help you refine your work and avoid major revisions later.  

Maintain a healthy school-life balance

While it is important to be dedicated to your PhD, it’s just as important to maintain a healthy work-life balance. Therefore, be sure to prioritize yourself! While finishing your PhD in less time is a great feat, it is important that you are not sacrificing your well-being while doing so.

Key Takeaways

• PhD stands for “doctorate of philosophy” and is generally the highest level of degree a student can earn
• There are many professional and personal benefits to earning a PhD which can lead to a serious return on investment
• A PhD program typically takes 4-7 years to complete. However, it can take longer or shorter depending on personal circumstances and field of study

How Long is a PhD?

Written by Kristine Bagdassarian

A full-time PhD in the UK usually takes between three and four years, while a part-time project typically lasts between five and six years.

The length and duration of a PhD depends on a range of factors, such as your funding arrangements, your country and institution of study, and the nature of your research topic. For example, if you’re doing a funded PhD you’re more likely to face completion deadlines than self-funded PhD students.

Increasingly, the type of programme you’re enrolled in can also affect the duration of your doctorate degree. Some projects or programmes now include additional training, teaching or projects that can extend your overall PhD registration period.

This page explains some of the factors that can affect the duration of a PhD.

On this page

How long does a full-time phd take in the uk.

Full-time study is the most common approach to PhD research, particularly for funded projects. You’ll normally spend at least three years of full-time PhD study on your topic, beginning with research and data collection before moving on to ‘writing up’ your work.

As with other levels of study, your PhD will be your main focus and you’ll be expected to dedicate a lot of your time on it. Some students do work part-time alongside their studies, but a full-time PhD itself can often be the equivalent of a full-time job.

Why three to four years?

Compared to other qualifications, a PhD takes a considerable amount of time.

When you are just starting, three to four years may seem like a long time to work on a single project, but the volume of work required to obtain a doctorate is substantial and many students find that the time goes by faster than anticipated.

By the end of this period, you’ll be expected to have completed any training required by your funding body and / or institution, gained research skills and conducted original research and, finally, submitted and defended your thesis. Some universities and projects may also expect (or even require) you to present your work at conferences or publish some of it during your doctorate.

In addition to this, it’s advisable to have engaged in extra-curricular activities and projects to boost your professional and academic skillset. Between three and four years is plenty of time to do this, but it’s nowhere near as long as it might seem.

For more information on what you can expect during your project, take a look at our introduction to PhD study .

PhD registration period and writing-up period

The stated duration of your PhD normally refers to the ‘registration period’ you set with your university at the start. This is the time period you intend to complete your PhD in and it will normally determine the ‘deadline’ for submitting your final thesis.

In the UK, the PhD registration period for full-time students is normally between three and three and a half years . In some departments and institutions, there is an understanding that students might enter a ‘writing-up’ period towards the end of their PhD. This is usually an extension to your registration, during which you don’t carry out any more research and just work on finalising your thesis and editing it for submission – writing it up, basically.

Can you complete a PhD in fewer than three years?

It’s technically possible to complete some PhDs in two years, if you have a very clear idea of the questions you want your project to answer and you’ve already done a lot of preparatory reading. This is very uncommon, however, and something that you should discuss with your supervisor. Some universities won’t let you submit a thesis before a certain point.

How many hours should I work while doing my PhD?

If you’re doing a full-time PhD, it’s wise to treat it like you would a full-time job, working the equivalent of 35 hours a week. However, you should be prepared to work longer hours during particularly busy stages of your doctorate, such as the writing up period and when you’re preparing for your viva.

Can you extend the length of a PhD?

Yes, it’s usually possible to extend the length of a PhD. You’ll need to apply to your university for an extended thesis submission date and have a valid reason for doing so (for example, a delay caused by something out of your control, COVID-19, a medical emergency or a bereavement). You should bear in mind that an extension isn’t guaranteed – particularly if it’s been caused by poor planning on your part. If your PhD has funding attached, there will usually be stricter deadlines than if you’re self-funding.

How long is an integrated PhD programme?

It’s quite common in STEM subjects to do an integrated PhD that includes a Masters qualification, usually taken after an undergraduate degree and referred to as a 1+3 PhD. These kinds of PhD typically take four years to complete.

If you have your eyes on doing research abroad, there are a few things you need to be aware of in terms of how long PhD study is. The three to four year PhD model is typical for the UK and most of Europe, with some countries in Asia also adopting a similar system (specific information on PhD studies in various countries can be found in our study abroad section ).

In the USA, a PhD takes four to six years . There are several reasons for this. While in the UK, you tend to apply for a specific project, in the US, your application is aimed at a certain department and your actual proposal takes shape in the first couple of years of PhD study. The US model involves a two-phase programme, wherein the first phase is focused on coursework and training and the second phase (typically from the third year onward) is when the bulk of the research is done. At the end of the second year, a US student would be expected to have developed a research proposal to be defended in front of a research committee and to have passed a ‘qualifying exam’ in order to present their defence.

How long is a part-time PhD?

Part-time PhDs normally take about twice the time of full-time PhDs (around five to six years in the UK ). You’ll do everything a full-time PhD student does across your doctorate, but your PhD work will be a less intensive part of your weekly routine.

This type of PhD is a good way to accommodate other employment and / or family commitments alongside your research.

In some cases, it may even be possible to start on a part-time PhD and switch to full-time study (or vice versa) if your situation changes.

How long does a distance learning PhD take?

Distance learning is an option if you’re unable to be physically present at your university. Most distance learning PhDs are also studied part-time and take around five to six years .

This option is increasing in availability, but can be trickier to manage in some fields that require regular lab work or access to specialist facilities. As a long-distance PhD student, you can expect to communicate with your supervisor via email, Skype or other electronic means as well as potentially attend the institution of your study for a couple of weeks each year.

The length of PhD funding

However you study your PhD, your funding situation can play a big role in determining how long your registration lasts – and / or how long you can afford to research for. Most scholarships and studentships have set lengths (which won’t necessarily cover writing up).

In some cases, funding can also add extra elements to a PhD, and potentially increase its overall length. Alternatively, limitations set by your department or research group funding could urge you to finish your thesis in the three-year period without additional extensions, while self-funded PhDs could greatly depend on your own resources.

Structured PhDs

In the UK, many PhD programmes funded by the Research Councils are offered as ‘structured’ or ‘new route’ PhDs. These incorporate additional training projects, professional internships and other elements.

Such elements may take place alongside your research, or specific time may be set aside for them. In some cases, students are only matched up with a supervisor at the end of the first year. These sorts of programmes are often offered within Centres for Doctoral Training (CDTs) or Doctoral Training Centres (DTCs) .

Registration period and funding period

Sometimes your registration period can also be tied to your PhD funding. Most studentships only last for a certain time (even if your doctorate ends up taking longer) and payments for a doctoral student loan will be based on the stated length of your project or programme.

Self-funded PhDs

Self-funding (unsurprisingly) is not restricted by funder deadlines and can be more flexible – particularly if you need to extend for writing up. However, self-funded PhDs require careful planning for tuition and living costs alongside any ‘hidden’ expenses, such as equipment and travel to events / conferences.

Although self-funding can ease the stress surrounding a strict final deadline, it is important to keep in mind that resources for support can place pressure on completion of the project. In addition, universities also still tend to set a maximum registration period.

• How Long Is a PhD Thesis?
• Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

• University of Edinburgh: 100,000
• University of Exeter: 100,000
• University of Leister: 80,000
• University of Bath: 80,000
• University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

• Arts & Humanities: 75,000
• Medicine, Dentistry & Health: 75,000
• Science: 80,000
• Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

• Average number of pages = 204
• Median number of pages = 198
• Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How long is a PhD dissertation? [Data by field]

The final piece of the PhD journey is the PhD dissertation. It takes many years to accumulate enough original and new data to fill out a dissertation to the satisfaction of experts in your field. Interestingly, the PhD dissertation length and content vary significantly based on the field you are studying and the publishing conventions.

A PhD can be anywhere from 50 pages to over 450 pages long. This equates to between about 20,000 words to 100,000 words. Most PhD theses are between 60,000 and 80,000 words long excluding contents, citations and references.

A PhD thesis contains different sections including an introduction, methods, results and discussion, conclusions, further work, and references. Each one of these different sections will vary in length depending on the field of study and your particular topic.

Ultimately, a PhD dissertation should contain as many pages and words as it takes to communicate the results of your multi-year investigation.

It is very rewarding to see your thesis come together as you are writing day after day. When I was writing my PhD dissertation I wrote the sections separately and my heart filled with joy when I finally put them all together and compile them into a single PDF document.

Counting the pages should not be the way to determine a PhD dissertation’s value but it certainly helps when your thesis is starting to look substantial in thickness.

How many pages should a PhD dissertation be?

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field. It has been created by Marcus Beck from all of the dissertations at the University of Minnesota.

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a PhD in your field.

Can a PhD dissertation be too long?

A PhD thesis should contain enough evidence and discussion to report on the most significant findings of your PhD research.

A PhD dissertation should not contain everything that you have done during your PhD. It should only include the data and information required to convince your PhD examining body that wraps up and tells the full story of particular lines of investigation.

Including random results, thoughts, or superfluous explanation can result in a dissertation that is unfocused. I have heard of music PhD is being described as too verbose and physical sciences PhD dissertations as being unfocused.

Therefore, a PhD thesis can be too long if the information it contains does not form a full and cohesive story.

One of my colleagues during their PhD removed an entire chapter from the thesis after writing it as the supervisor said that it needed more experiments to be a full story. They did not want to spend the next six months gathering the data and simply removed the chapter altogether.

How short can PhD dissertation be?

The shortest PhD dissertations are typically found in mathematics.

George Bernard Danzig was an American mathematical scientist who made contributions to industrial engineering and many other mathematical-related fields. An interesting miscommunication led to 1 of the shortest PhD theses ever.

In 1939 his professor wrote two problems on the blackboard and Danzig thought they were homeless assignments. He stated that they were harder than usual but handed in solutions to the surprise of the professor.

They were, in fact, open mathematical problems in statistics.

His professor said to bind the solution to the two problems together and submit them as his thesis – the total thesis length = 14 pages.

Obviously, most PhD theses and dissertations will be so much longer than that!

My PhD dissertation was 256 pages long. It was full of schematics, diagrams, and tables to demonstrate and communicate my findings.

I would say that most people’s PhD thesis experience will be closer to mine than Prof George Bernard Danzig’s.

Why PhD dissertations are typically so long

PhD dissertations are often over 200 pages long.

One of the primary reasons they are so long is that it is a single document that summarises many years of hard work. Also, summarising the research field to date and making sure that all of your references and citations are included so you avoid plagiarism will bolster the word count of the thesis dramatically.

Here are all of the reasons PhD dissertations tend to be so long.

Many years of work

PhD theses or dissertations contain many years of research and analysis.

In many of my YouTube videos I recommend that a PhD student work towards their PhD thesis by doing at least three hours of focused work every work day.

This amount of work quickly adds up.

Of course, not every bit of work makes it into the PhD dissertation but a lot of it does. It can be difficult to work out what to include or leave out of your thesis.

As a PhD student, I perfected the art of turning one experiment into many different types of grafts and schematics to fully explore the limits of my data. The graphs can take up a lot of space in your PhD thesis and, therefore, bolster the page count significantly.

In depth literature review

One of the most substantial parts of a PhD dissertation is the literature review.

The literature review can take up a huge portion of the early part of your PhD dissertation depending on the amount of data and publications in your field.

Writing an in-depth literature review requires just as much meticulous data analysis and searching as the central part of your dissertation.

Figures and schematics

Some fields end up producing a lot of figures and schematics.

My thesis had many full-page figures of atomic force microscopy experiments with much more explanation on subsequent pages.

As they say, a picture paints a thousand words and a dissertation can really benefit from having many schematics to highlight the important aspects of your findings.

References and citations

The recommended PhD dissertation word count from an institution or university does not include citations, references, or other thesis parts such as summary of abbreviations, table of figures, et cetera.

However, these components of your dissertation can take up many pages and add to the overall thickness of your PhD dissertation.

University formatting rules

University formatting rules will also dictate how you many pages your words take up.

I often get roasted on my YouTube channel for having doublespaced lines and wide margins. Unfortunately, this layout was dictated by my university before printing.

PhD dissertations often end up going into long-term storage and therefore, need to adhere to archival and standardised formatting rules.

Deep in the depths of the University of Newcastle, there is a copy of my thesis on a shelf. The formatting and binding rules mean that my thesis looks like everyone else’s.

Universities will often have their own requirements for PhD dissertation cover colour, quality, and type of paper. Even the quality of the paper can change the thickness of the PhD dissertation significantly.

PhD by publication

It is becoming increasingly common to submit a number of peer-reviewed papers bound together with supplementary information in between instead of a PhD dissertation.

The benefits of this to the researcher and university are:

• More early career peer-reviewed journals for career advancement
• an easier review process – they have already been peer-reviewed
• an early focus on publishing means better research outcomes for the researcher, supervisor, and Department.
• No mad rush at the end to finish a thesis
• continually writing peer-reviewed papers throughout your PhD helps with timely analysis and communication of results

Even though this option has been available to PhD students for a number of years, I have only known a handful of students actually submit their PhD via publication.

Nonetheless, having this option will suit some research fields better than others and lead to a more productive PhD.

Wrapping up

This article has been through everything you need to know about the length of a PhD dissertation and the common lengths of PhD dissertations for various fields.

Ultimately, there is no predefined length of a PhD .

A PhD thesis is as long as it needs to be to convince your examiners that you have contributed significantly enough to an academic field to be awarded the title of Dr of philosophy.

Mathematical and analytical theses tend to be shorter and can be as short as 50 pages (with one of the shortest being only 14 pages long). At the other end of the spectrum, PhD students in anthropology and history tend to produce the longest dissertations.

Dr Andrew Stapleton has a Masters and PhD in Chemistry from the UK and Australia. He has many years of research experience and has worked as a Postdoctoral Fellow and Associate at a number of Universities. Although having secured funding for his own research, he left academia to help others with his YouTube channel all about the inner workings of academia and how to make it work for you.
