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.

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."

He adds that prospective Ph.D. students who already have master's degrees in the field they intend to focus their Ph.D. on should investigate whether the courses they took in their master's program would count toward the requirements of a Ph.D. program. "You’ll want to discuss your particular situation with your program to see whether this will be possible, and how many credits you are likely to receive as the result of your master’s work," he says.

How to Write M.D.-Ph.D. Application Essays

Emmanuel C. Nwaodua, who has a Ph.D. degree in geology, says some Ph.D. programs require candidates to publish a paper in a first-rate, peer-reviewed academic journal. "This could extend your stay by a couple of years," he warns.

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.

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.

Kee adds that humanities Ph.D. programs often require someone to learn a foreign language, and "fields like anthropology and art history require extensive field research." Kee says funding for a humanities Ph.D. program typically only lasts five years, even though it is uncommon for someone to obtain a Ph.D. degree in a humanities field within that time frame. "Because of this, many if not most Ph.D. students must work to make ends meet, thus further prolonging the time of completion," she says.

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.

Online Doctoral Programs: What to Expect

Kristin Redington Bennett, the founder of the Illumii educational consulting firm in North Carolina, encourages Ph.D. hopefuls to think carefully about whether they want to become a scholar. Bennett, who has a Ph.D. in curriculum and assessment and who previously worked as an assistant professor at Wake Forest University , says a Ph.D. is most appropriate for someone who is a "lifelong learner." She says someone contemplating a Ph.D. should ask themselves the following questions "Are you a very curious person... and are you persistent?"

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.

Curtis says a prospective Ph.D. student's enthusiasm for academic work, teaching and research are the key criteria they should use to decide whether to obtain a Ph.D. degree. "While the time it takes to complete a doctorate is an understandable concern for many, my personal belief is that time is not the most important factor to consider," he says. "Good Ph.D. programs provide their students with generous stipends, health care and sometimes even subsidized housing."

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 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.

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.

Editorial Listing ShortCode:

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.

What is a doctorate.

A doctorate is a research-based academic degree. It is considered a terminal degree in most disciplines, meaning it represents the highest level of education a student can obtain in their chosen field.

A doctorate is awarded to students who have undergone a lengthy research process and made a significant contribution to the body of knowledge in their field of study. It takes multiple years to complete, during which students work closely with a supervisor and focus on a specific dissertation topic. Completing a doctorate might also involve teaching and comprehensive examinations.

A doctorate serves as solid proof of a person’s level of knowledge and expertise. It demonstrates that you have mastery over your chosen subject, and helps establish you as an expert. This level of expertise comes with top-tier job opportunities and the potential to earn top salaries in your chosen profession.

Doctorate vs PhD: Key Differences

While many people use the terms doctorate and PhD interchangeably, there are key differences between the two. These differences have to do with the application of these degrees. However, both terms refer to terminal degrees, so they hold the same value.

A Doctor of Philosophy degree, or PhD, is a research-oriented degree that demonstrates a person’s ability to contribute new knowledge to their chosen field. A student who pursues a PhD usually does so to answer a specific question, conduct original research to provide an answer, and use their findings to advance their field.

On the other hand, the term doctorate is broader and typically refers to a professional or clinical degree. This means that a person who obtains it has demonstrated an ability to apply advanced knowledge in a particular field in their professional life. Professional doctorates of this kind are awarded, for instance, to medical doctors or doctors of juridical science.

PhD Requirements: How to Get a PhD

While each PhD degree program will have unique requirements depending on the school and field of study, there are some common requirements you need to complete to get a PhD. Keep reading to find out about the most common requirements to earn your advanced degree.

PhD Statement of Purpose

A PhD statement of purpose is a document that clearly outlines your goals for your PhD, your academic credentials, and the reasons why an academic committee should approve your project. It is typically between 500 to 1,000 words long and gives prospective students an opportunity to explain how their research project will make a relevant contribution to their field.

How Many Credits Is a PhD?

Typically, it takes between 90 and 120 credits to complete your PhD studies. However, this number can be as low as 60, depending on the degree type, area of study, and state, regional, or institutional requirements. Credit hours for graduate students are usually divided between course work, research hours, and dissertation work.

Other Common Requirements for a PhD

• Coursework. While coursework is not the main focus of a PhD, students will usually have to enroll in a few core courses during their first or second year of grad school. They might also have the opportunity to enroll in elective courses, which offer a chance to learn about other fields of study.
• Qualifying exams. A common component of many PhD programs is a set of qualifying exams. Students must successfully pass these comprehensive exams toward the end of their degree in order to demonstrate their level of competence in their field. These tend to be oral exams.
• Teaching. Many PhD programs include a teaching component. Students are required to teach basic courses, typically to fresh undergrad students, which helps them develop teaching skills.
• Research. Conducting original research on a particular subject is typically the main component of a doctorate program, and takes up the bulk of doctoral candidates’ time.
• Dissertation. Throughout their program, PhD candidates need to complete a dissertation based on the original research they’ve conducted. Graduate students do this under the guidance of a qualified faculty member.
• Dissertation defense. Once the dissertation is approved, PhD students need to successfully defend their research in front of a panel of experts in their field before they are awarded their degree. This is the final step in the dissertation process.

How Do PhD Programs Work?

Typically, PhD degree programs work based on a mix of coursework and research conducted over three to four years, although this can last longer depending on the program and the pace at which a student completes their research. Coursework is typically completed towards the beginning of the program, and towards the end, the dissertation or thesis becomes the main focus.

In addition, students must fulfill other program requirements throughout this period. This might include teaching undergraduate students, completing a residency, passing qualifying exams, or attending conferences or colloquia. The final step is usually an oral defense in front of a panel of experts, who are selected to evaluate the quality of the research and the value of the results obtained.

Do You Need a Master’s to Get a PhD?

No, a master’s degree is not always required to pursue PhD studies. Many programs in the US allow students to apply to a PhD program straight after completing their bachelor’s degree. Other programs offer dual degrees, meaning that you will obtain a master’s degree while you work toward your doctorate.

What Comes After a Doctorate Degree?

In many fields, the usual step after a doctorate degree is a postdoc. This is an option for those wishing to pursue a career in academia and continue doing research in their field. However, an academic career is not the only option. Because a doctorate is a terminal degree, graduates can easily move on to professional positions in other types of organizations in their chosen field.

PhD Dissertation vs Thesis

The main difference between a dissertation and a thesis is the scope of the research being conducted and the type of degree you are awarded after completing it. Often, the terms are used interchangeably, or they can hold different meanings in European countries, which causes some confusion regarding their nature. Keep reading to understand the differences between a PhD dissertation and a thesis in the US.

What Is a PhD Dissertation?

A PhD dissertation is a piece of scholarly work that presents the original research carried out by a doctoral student during the length of their program. It discusses the scope, methodology, results, and conclusions of the research at length. The end goal of a doctoral dissertation is to produce results that help advance human knowledge in a given field.

PhD Dissertation Defense

A PhD dissertation defense is the process in which a PhD candidate defends their research in front of a panel of experts in their field. During the defense, members of the panel ask questions regarding the information presented, providing the candidate an opportunity to back up their work and demonstrate the level of expertise they’ve achieved after years of dedicated work.

What Is a PhD Thesis?

In the US, as opposed to some European countries, the term thesis refers to a shorter academic paper that is usually presented for the completion of a master’s degree. It can also sometimes be a requirement for honors students completing a bachelor’s degree. The information presented in a thesis is usually drawn from existing sources, rather than from original research conducted by the student.

PhD Thesis Defense

A thesis defense is usually not a mandatory requirement for master’s students, although this varies according to your school and department. The thesis is still an in-depth piece of scholarly writing and serves as a testament to a student’s mastery of a given subject, and a defense serves as an opportunity to engage a panel of experts and defend the contents of your paper.

How Long Does It Take to Earn a Doctorate?

Most doctoral programs are designed to be completed in four to six years. However, it can take up to seven and a half years to earn a doctoral degree from the start of graduate school, according to data presented by the National Science Foundation.

A number of factors can affect how long it takes students to earn their PhDs. They include the structure of their chosen program, the type of research being conducted, and the support provided by the institution. On average, students completing doctoral programs in science and engineering fields finish faster than their counterparts in non-science and engineering fields.

How Hard Is It to Get a PhD?

It can be very hard to get a PhD. Working for several years on a particular dissertation topic can be very trying. Aside from the time commitment, the depth of research that is part of the dissertation process can also be challenging. Admissions to a top education institution can be extremely competitive, as usually there are only a handful of positions available for hundreds of applicants.

What Is the Easiest PhD to Get?

PhDs in the humanities, social sciences, and education are typically regarded as the easiest to obtain. However, this truly comes down to how interested you are in your chosen dissertation topic and your level of commitment to making a relevant contribution to human knowledge, both of which can greatly influence your perception of the difficulty of the degree.

How Much Does a PhD Cost?

According to data from the National Center for Education Statistics, the average yearly cost of graduate programs in the US is $19,792. Data from the QS World University Rankings suggest that the yearly cost of a PhD in the US ranges from $28,000 to $40,000. The total cost of a PhD can greatly vary depending on the university, length of the program, and funding options available for doctoral study.

How to Earn a Doctoral Degree

So, how do you earn a doctoral degree? While there is work to be put in, the process is actually quite straightforward. Keep reading to find out how you can embark on the path toward your PhD.

The first step to earning your doctorate is to complete a bachelor’s degree at the undergraduate institution of your choice. Depending on your chosen field, you might need to obtain a degree in a specific discipline, which can then pave the way for your graduate studies.

If a bachelor’s degree is not an option right away, you can start by obtaining an associate degree , which can even be done through the best online community colleges . While you obtain your undergraduate degree, make sure to seek out career advice from experts who can help you decide how to best use your time and embark on the right academic path.

While earning a master’s degree is not mandatory to apply to a PhD program, doing so can offer you a competitive advantage. It will give you a chance to deepen your knowledge on a particular topic, connect with professors and gather recommendations, and test the waters regarding your chosen field.

In order to successfully apply to a master’s degree program, you will have to provide your GPA, letters of recommendation, and sometimes standardized test scores. For instance, if you’re interested in pursuing a Master’s Degree in Mathematics , you will need to prep for the GMAT and submit your scores. Be sure to check the requirements of your chosen school and department.

Whether you have completed your master’s or are applying straight after your bachelor's, make sure to spend some time choosing your specific research area and the type of PhD you wish to pursue. This is also an excellent time to assess funding opportunities and contact potential supervisors to gauge their interest in and ability to support you during your studies.

In order to enroll in a doctoral program, you will need to provide quite a few documents with your application. Every school is different, but the most common requirements are transcripts, letters of recommendation, and a strong statement of purpose. Make sure you check the specific requirements of your chosen program, and prepare to be interviewed by faculty members.

After being accepted into a doctoral program, you should outline what the next few years will look like. What requirements do you need to complete to earn your PhD? Spend time crafting a realistic timeline that can help you stay on track and complete every step successfully. This includes teaching, participating in conferences, and successfully completing your qualifying exams.

The final step to obtaining your PhD is to successfully complete your research and compile your results in your dissertation. Once it is reviewed and approved by your supervisor and readers, you will have to defend it as well. It can be a trying process, but the results will be worth it.

How to Choose a PhD Program

In order to choose a PhD program that is right for you, there are several factors you should consider. A PhD is a strong commitment both in terms of time and money, so the decision shouldn’t be made lightly. Keep reading to find out how to choose a PhD program.

PhD Acceptance Rates

The PhD acceptance rates of a university give you an idea of how likely you are to be admitted to your chosen program. This number is a reflection of how competitive a program is and the funding the department receives. Use this information to orient yourself to the selection process, as applying to a variety of programs with different acceptance rates can increase your chances of being accepted into one of them.

Keep in mind that acceptance rates are usually measured by department, not university. For instance, Columbia University has an acceptance rate of four to six percent for its psychology PhD program , and an acceptance rate of five to seven percent for its history PhD .

PhD Dropout Rates

PhD dropout rates are important to consider, as they give you an idea of how supported students are in a particular program and how likely you are to complete your doctorate. In the US, PhD attrition rates, or dropout rates, can range from 40 to 50 percent , so take your time to find a university and program with a high success rate to ensure you will be able to finish and obtain your degree.

Faculty Members

One of the key relationships you will have during your time as a PhD student will be with your supervisor. You will also be working closely with other members of your department. As such, make sure to research the faculty to ensure that their interests and research projects align with your own. During the research stage, you can even reach out to them to find out about the department, ask about funding opportunities, and receive relevant career advice.

Funding Opportunities

A PhD can be costly, but there are many ways to offset those costs to make it more manageable. Be it scholarships, grants, or work opportunities, make sure to research all funding opportunities available so you can select a program that aligns with your financial situation. Many universities offer fully-funded programs to outstanding students, so do your homework and find a program that doesn’t leave you financially crippled in the long run.

When you commit to a PhD, you are also committing to several years of work. Unless you are planning to complete your program fully online, you should take into account the place where you will be moving to continue your studies.

Do you prefer big cities or small college towns? Which part of the country would you be willing to relocate to? Take some time to reflect on your preferences so you can choose the best location according to your needs and preferences.
