doctor phd meaning

“M.D.” vs. “Ph.D.” vs. “Dr.”: Are They Synonyms?

Quick: when you hear the word doctor , what do you picture?

Most would probably describe someone in a white lab coat with a stethoscope hanging around their neck or someone in medical scrubs—someone you would seek out if you have a deep cut that needed stitches.

That word doctor , however, is a title assigned to many who don’t come close to that description, many of whom you wouldn’t want stitching up that cut. Take your English professor, for instance. No offense, Dr. Barrett. 

It can all be a bit confusing, which is why it’s important to know who and why someone might be called a doctor , as well as what all those initials and abbreviations after their name mean. Here we break it all down.

What does Dr. mean?

Let’s start with doctor or D r . for short. While the first definition of the word is “ a person licensed to practice medicine,” that doesn’t mean you want to take medical advice from anyone who calls themselves a doctor . There are many looser definitions of the word that follow and, frankly, make things a bit confusing.

For example, the third definition is older slang for a “cook, as at a camp or on a ship,” while the seventh entry is “an eminent scholar and teacher.” Bugs Bunny didn’t help matters either by plying anyone and everyone with his famous greeting,“What’s up, doc?” 

The term doctor can be traced back to the late 1200s, and it stems from a Latin word meaning “to teach.” It wasn’t used to describe a licensed medical practitioner until about 1400, and it wasn’t used as such with regularity until the late 1600s. It replaced the former word used for medical doctors— leech , which is now considered archaic. 

WATCH: When Did The Word "Doctor" Become Medical?

Physician vs. doctor : are these synonyms.

While the term physician is a synonym for doctor , it’s typically used to refer to those who practice general medicine rather than those who perform surgery, aka surgeons . 

A quack , on the other hand, is defined as “ a fraudulent or ignorant pretender to medical skill.”

What does M.D. mean?

Moving on to initials that carry more weight than a nod from Bugs, let’s look at M.D.s .

M.D. , which can be used with or without the periods ( M.D. or MD )  is the designation for a medical doctor. This is earned by attending medical school (typically a four-year program after completing at least one undergraduate degree, plus a residency program), and learning to diagnose patients’ symptoms and offer treatment. 

The initials M and D stem from the Latin title  Medicīnae Doctor. There are many different types of doctors, with different specialties, but if you have a physical ailment, visiting a doctor with the initials M.D. is a good place to start.

Specialty doctors may add even more initials to their title, such as DCN (doctor of clinical nutrition), DDS (doctor of dental surgery), or countless others they acquire with additional training. To make things even more confusing, some may add abbreviations from medical associations they belong to, such as FAAEM (Fellow of the American Academy of Emergency Medicine).

What does Ph.D. mean?

As for Ph.D. , this stands for “doctor of philosophy.” It stems from the Latin term Philosophiae Doctor.

You can get a Ph.D. in any number of subjects, from anthropology to mythological studies. It’s not an easy feat, however, as to earn one, you must do original research and write a dissertation . 

Ph.D. vs. M.D .: are these synonyms?

There are two big differences between Ph.D. s and M.D .s. When it comes to medicine, M.D.s can prescribe medications, and Ph.D.s can’t. And yes, it’s possible to be both an M.D. and a Ph.D. In fact, some med schools offer programs in which you can achieve both simultaneously. 

You can also get a professional doctorate degree in a number of fields. For example, you might receive a doctorate of education, an  Ed.D . 

So, in a nutshell, both M.D.s and Ph.Ds can be referred to as doctors . If you’re looking for someone to treat what ails you physically, then you want at least an M.D. following their name. If you want to dig deep into a subject and get advice from someone who has done their own research and who likely knows the latest and greatest developments in a particular area, then you’re probably looking for a Ph.D. And if someone has both, even better—depending on your needs, it may be just what the doctor ordered.

Doctorate vs PhD: What’s the Difference?

Quick Highlights:

• All PhDs are doctoral degrees, while not all doctorates are PhDs.
• Both are doctoral degrees, but a PhD is specifically academic and focused on original research.
• Professional doctorates (like an Ed.D, M.D., DBA) are applied and tailored to specific professions.
• In most cases, you’ll need to complete a bachelor’s and a master’s degree before pursuing a doctoral degree.

The difference between a doctorate and PhD is one of categorical grouping. Simply put, a doctorate is an umbrella term for an advanced degree beyond that of a master’s degree. In other words, all PhDs are doctorates, while not all doctorates are PhDs. Here’s a simple graphic to help you visualize the concept:

In other words, a PhD–which stands for Doctor of Philosophy–is a special kind of doctorate degree, while a doctorate degree refers to the higest degree available in various fields. So a PhD is a doctorate, but a doctorate is not necessarily a PhD.

The distinction between a PhD and a Doctorate can be quite meaningful depending on your academic and professional goals. So read on to learn about the various types of doctoral degrees, the difference between them, and why they’re important.

What Is a Doctoral Degree?

A doctoral degree is a general term for a terminal degree that usually is awarded when someone pursues their studies beyond the level of a bachelor’s and a master’s degree. Doctoral degrees can be awarded in any number of fields, from education and English literature to chemistry and calculus.

Doctoral degrees typically come in two forms:

• a professional (also known as applied doctorate)
• an academic doctorate

Related: What is a Terminal Degree?

What is an Applied Doctorate Degree?

Professional or applied doctorate degrees qualify someone to work in a specific profession. This includes things like:

Doctor of Medicine (M.D.)

Doctor of Business Administration (DBA)

Doctor of Education (Ed.D.)

Degree holders with a professional doctorate degree are qualified to work at the highest level within their field. 

These professional degrees require academic research. It will culminate in a dissertation which must be defended in front of a group. A dissertation, like a thesis, is a lengthy and involved paper that incorporates research and applies a theory to make advances within the field.  

Some of the most common fields for a professional doctoral program are:

• Physical therapy
• Osteopathic medicine
• Occupational therapy
• Educational leadership
• Medicine 

We’ll discuss a few of the most common professional doctorate degree programs below.

Related: What Is The Difference Between College and University?

An Ed.D. is a professional doctorate for educators with teaching and administration responsibilities as well as those working in nonprofits and governmental agencies. These programs offer advanced leadership training which can help students advance their career. Students learn effective strategies to solve real-world problems they’ll encounter out in the field.

Ed.D. programs do not follow a standard curriculum. Each program is unique, and many can be tailored to meet the needs of each individual student. Some are offered online while others follow a more traditional format.

Doctor of Business Administration

The DBA is a professional degree for business professionals. These programs build upon the skills taught in an MBA program. Students are often accomplished executives who want to be better, more innovative business leaders.

DBA students conduct practical research that directly applies to the business world. Students will develop new insights and solutions to business challenges.

Doctor of Psychology (PsyD)

Psychology is an area where students can choose to complete either a Ph.D. or a PsyD degree. A PsyD degree emphasizes the clinical and applied aspects of psychology. This degree is growing in popularity for several different reasons:

• Completion time is often less than a traditional PhD
• Specialization options
• Opportunity to complete a dual degree (MSW or MPH are popular)

The PsyD focuses on practice over research so students begin working on fieldwork sooner in the program. This hands-on experience is valuable as students begin to build their professional portfolio.

An M.D. is the degree of choice for students planning a career in medicine. These highly competitive and rigorous programs include the classroom and intensive training students need to join the medical field.

M.D. programs usually require students to complete four years of medical school followed by a residency. The residency can take between two and five years depending on the area of medicine.

While an M.D. degree requires a significant commitment of time and money, the investment plays off with a high salary and job security.

Doctor of Optometry (O.D.)

An O.D. an expert in primary eye care. They diagnose and manage diseases and disorders of the eye. An O.D. degree can take between eight and nine years of education beyond high school. Students take classes in areas like:

• gross anatomy
• neuroscience
• biochemistry

An optometrist can determine if an individual needs corrective lenses or contacts to improve their vision. They can check for signs of glaucoma or other degenerative eye conditions. In some states, an optometrist can prescribe certain medications.

Regardless of the individual field that you pursue, you can know that a doctoral degree will make you a highly qualified candidate for upper level positions in your field. 

What Is a Doctor of Philosophy (Ph.D.) Degree?

Academic doctorates, on the other hand, are degrees that qualify someone to study, research, or teach at the highest level in his or her field. At some schools, like Franklin University, professional doctorates are referred to as an application oriented-degree while Ph.D.s, or academic doctorates, are referred to as research degrees. 

A Ph.D. is actually a specific type of doctoral degree. This means that rather than being completely separate from one another, Ph.D.s are really just a specific subtype of the umbrella term “doctorate degree.” 

A Ph.D. is an academic degree focused on original research and the application of new ideas to existing knowledge. This research based degree emphases research skills that allow student to contribute to the advancement of their field. Lots of people falsely believe that a Ph.D. is limited to fields in the social sciences. This is likely due to the word “philosophy” in the title. Rather than meaning philosophy in the modern sense, though, the word philosophy in a Ph.D. refers to its Latin origins, meaning “love of wisdom”. 

The reality is that Ph.D.s are research degrees available in many fields. Some of the most common degree fields for a Ph.D. include:

• Applied mathematics
• Accounting and finance
• Biomedical engineering
• Chemical engineering 
• Clinical psychology
• Computer science
• Counseling psychology
• Data analysis

No matter what kind of Ph.D. you undertake, you will always graduate from a Ph.D. program with a high level of competence, respect, and mobility within your career field. 

How To Apply for a PhD vs Doctorate Program

Once you’ve made the choice between a professional degree versus doctorate , you’ll need to figure out how to apply to your chosen program. Because Ph.D. programs are simply a specific type of a doctorate program, the application process varies more by school than it does by degree type. 

In general, when you apply to a doctoral program, you’ll need to have already completed a bachelor’s and a master’s degree. In many cases, your bachelor’s degree can be in any field. It does not need to be related to the field you’re pursuing at the professional level. In most cases, your master’s does need to be related in some way. 

If it’s not, there’s a strong likelihood that you’ll need to complete some prerequisite graduate-level classes before you can apply for your doctorate program. You’ll need to check with each program about the prerequisites before you apply. 

Once you’re sure that you meet the prerequisites required of a doctoral student, you’ll also need to get your application materials. Generally this means:

• transcripts from your undergrad and graduate school coursework
• letters of recommendation
• an essay or statement of purpose
• recent GRE or GMAT scores

Again, application requirements will vary by school so you’ll want to check directly with those you’re applying to. 

PhD vs Doctorate Degree: Which is Longer?

The amount of time it takes to complete your doctorate vs PhD degree will largely depend on what work you’ve done before it, and whether you’ll be pursuing it part-time or full-time. If you have completed a master’s in the field already, you will need to complete fewer credits to complete the doctoral degree. 

At some schools, there is an option to combine your master’s with your doctorate degree. These accelerated programs usually allow you to take a year of study off your total commitment.

Still, terminal degrees are no small time commitment. Most degrees take anywhere from five to eight years to complete when pursued full-time. In general, Ph.D. programs tend to take slightly longer than professional doctorates. For example, to complete a doctor of education (Ed.D.) degree, doctoral students must complete at least 60 credits. In contrast, Ph.D. students completing a Ph.D. in Education must complete 90 credits. 

Earning Potential of a Professional Doctorate vs PhD

While a professional doctorate and a Ph.D. are seemingly very similar, they do differ in terms of earning potential. 

This is likely because many Ph.D. programs lead to careers in teaching or research. These are two fields that are notoriously low in funding, unless you find one of the relatively less common highly paid positions in these fields. 

According to the Bureau of Labor Statistics, the average salary for a postsecondary teacher at colleges or universities is about $80,000. The average salary of postsecondary teachers in the field of scientific development and research is more, at nearly $110,000, and the average salary of a researcher in the field of medical science is nearly $90,000. 

Compare these salaries to those of professional doctorates like a medical doctor or a lawyer. A medical doctor earns an average salary of $208,000 while a lawyer receives an average salary of roughly $123,000. 

Doctoral Degree vs PhD: How Do They Stack Up?

While a Ph.D. is simply a subtype of doctorate, there are some distinct differences that set it apart from professional doctorate degrees. 

While Ph.D.s are typically heavy on research, professional doctorates are heavy on application of knowledge to a specific professional field. The body of knowledge developed in a Ph.D. program may be slightly broader, while the knowledge built in a professional doctorate program is tailored more directly to a specific career. 

Both programs have similar application processes, but the Ph.D. program may take slightly longer to complete on average than the professional doctorate program does. Finally, professional degree PhD program graduates tend to earn slightly more than Ph.D. graduates. 

If you’re interested in pursuing a doctorate degree, you’ll need to consider a professional doctorate degree vs PhD. You’ll want to research your programs before applying. Sites like CollegeRank can help you to narrow your options by providing curated college rankings geared to a number of different factors, from campus size to return on investment, and more. 

What kind of research is required in a PhD compared to a professional doctorate?

According to the Council of Graduate Schools , A PhD requires students to conduct original research that contributes new theoretical insights to their academic field. This often involves extensive data collection, hypothesis testing, and the development of a dissertation that advances academic understanding in your chosen area of focus.

In contrast, professional doctorates focus on applied research , which is aimed at solving practical problems in a professional context. Instead of a dissertation, professional doctorate students typically complete a capstone project or applied research paper that addresses real-world issues within their field.

Which type of degree is better suited for someone interested in teaching at the university level?

A PhD is generally better suited for those looking to pursue a career in academia or research, especially in tenure-track university teaching positions. Universities typically prefer candidates with a PhD for roles that involve teaching, mentoring graduate students, and conducting research. However, professional doctorates can also be valuable for teaching, particularly in fields like education or business where applied knowledge is critical.

Do professional doctorates take less time to complete than PhD programs?

Professional doctorates, such as EdD or DBA, often take less time to complete compared to PhD programs. PhDs typically require 4-7 years due to extensive research and dissertation work, while professional doctorates usually take 3-6 years. Although with the introduction of accelerated doctoral programs, these timelines will vary depending on the university that you choose.

Can someone with a professional doctorate still contribute to academic research?

Yes, individuals with professional doctorates can contribute to academic research, particularly in applied fields, but the focus of their research is typically on solving real-world problems rather than advancing theoretical knowledge.

Is a PhD or a Doctorate degree more recognized in non-academic careers?

Professional doctorates are more recognized in non-academic careers due to their focus on applying knowledge to professional practice. A PhD , while respected, is generally more suited for academic and research roles.

What Does 'PhD' Stand For?

A PhD is a terminal academic degree students typically pursue when they're interested in an academic or research career.

A PhD is the highest possible academic degree a student can obtain. PhD stands for “Doctor of Philosophy,” which refers to the immense knowledge a student gains when earning the degree. While you can actually get a PhD in philosophy, "Doctor of Philosophy" doesn't always refer to someone who has a terminal degree in that discipline. You can get a PhD in a number of fields, such as science or economics, and the word "Philosophy," translated from original Greek to mean "lover of wisdom," can refer to the degree holder's dedication to understanding a subject.

Students typically pursue a PhD when they're interested in an academic or research career—or if they want to take their education as far as it can go.

This article goes beyond the definition of a PhD, and touches on important information you’ll need to know about the degree, so you can decide whether pursuing one is the best choice for you. 

What is a PhD? 

A PhD is an academic degree that combines general knowledge of a field with specific mastery of an area of subtopic within that field. For example, earning your PhD in political science means you have a general foundation of the field, but likely also specialize in a more focused area, such as American or comparative politics, or political economy. 

PhDs—also known as doctorates—are terminal degrees , meaning they are the highest level of degree that you can achieve in certain fields, such as cognitive psychology, mathematics, English, economics, evolutionary biology, and public health.

What does it take to earn a PHD? 

PhD programs typically require you to complete advanced coursework, comprehensive exams that test your knowledge of your particular field of study, and a dissertation (or original body of research). The specific requirements will differ by program or university.  

How long does a PhD take?

Your PhD studies can take between four and seven years to complete, though it often depends on your field and other commitments. For example, it typically takes less than seven years to earn an engineering PhD, while it can take up to 12 years to earn an education PhD. Writing a dissertation is often credited with adding to the length of time it takes to complete a PhD program. In addition, some doctoral students may be working full-time or raising families while completing degree requirements, and thus may need additional time in their programs.

Getting a PhD: what to know

If you're considering getting a PhD, there are some important aspects of doctoral degrees you'll need to know. 

To apply for PhD programs, you'll need to provide academic transcripts from your prior education, samples of your academic writing and research, and letters of recommendation from former professors. You will likely also need to write a personal statement that details your academic and professional goals, research interests, why you are applying to a particular program, relevant skills and experience, and strengths.  

Before applying, it's a good idea to research different education institutions to get an idea of their reputation, faculty achievements, mission statements, and the kinds of jobs former graduate students have gotten upon completing. 

Once enrolled in a doctoral program, expect to complete advanced study in your field. This will likely entail two years of coursework, conducting original research into a specific topic, navigating the world of academic publishing, and working closely with faculty to prepare for an academic or research-based career. 

Successful completion of a PhD program typically requires that you write a dissertation or conduct a significant research project on a specific topic related to your field. Most programs have students go through an oral defense to demonstrate mastery of the dissertation topic and describe its contribution to the field. 

PhDs vs. other terminal degrees

A PhD is not the only kind of terminal degree you can earn. In fact, there are two other types of terminal degrees that tend to be more career focused.

Professional doctorates

PhDs and professional doctorates are similar in that they are both the most advanced academic degrees you can earn, but a PhD requires a dissertation and a professional doctorate requires a doctoral study. 

PhDs are focused on producing original research, whereas professional doctorates typically have some professional experience they apply toward researching a solution to a practical problem. If you have significant experience in a professional field, such as business administration or public health, you might choose to pursue a professional doctorate because you can use your knowledge and expertise in more concrete ways. 

Professional degrees

A professional degree is the PhD equivalent for certain professions, like for a medical doctor, dentist, or lawyer. Whereas a PhD tends to promote a historical and theoretical education, a professional degree emphasizes a practical education because it’s designed for you to begin working in medicine or law after you graduate and pass additional licensing requirements. 

Did you know?

Honorary degrees at the PhD level are conferred upon people who've made significant contributions to a field or society at large. An "honorary" degree refers to an academic award that distinguished individuals can receive from an academic institution without having to complete the usual requirements of the degree. Here are some celebrity examples:

Meryl Streep has received honorary PhDs from Harvard, Yale, Princeton, and the University of Indiana at Bloomington for her cinematic achievements.

Oprah Winfrey has received honorary PhDs from Princeton, Howard University, Duke University, and Harvard for her philanthropic and business achievements.

John Legend has received honorary Doctorate of Music from the University of Pennsylvania and an honorary doctorate from Howard University.

Education requirements for a PhD 

Obtaining your PhD requires earning your bachelor’s degree and likely your master’s degree before you can begin applying to doctorate programs. However, there are some programs that combine the master’s degree with the PhD so that you spend less time earning both and can begin once you finish your bachelor’s degree. 

Let's look at the two most important degrees you’ll need to complete before you can begin pursuing your PhD.

Bachelor’s degree

You will need to earn a bachelor’s degree before pursuing more advanced degrees, like a master’s or PhD. You don’t have to choose a major related to your eventual doctorate, though it can help to pick a complementary subject so you have a strong foundation before taking higher-level coursework. For example, if you want to obtain a PhD in economics, then it might help to major in economics, finance, business, or even political science as an undergraduate. 

While graduate programs don’t always expect applicants to have studied the same field as the one they’re applying to, you will need to explain your interest in the field of your potential graduate work and have some knowledge about what you want to study within it. Aligning your undergraduate and graduate focuses may also help you move through your graduate coursework faster.

Master’s degree

A master’s degree is an advanced degree you can pursue after earning your undergraduate degree. PhD programs typically require a master’s before admitting you, though as we noted above, some programs may combine degree tracks to decrease the amount of time to completion.

Master’s degrees take between one and three years to finish , depending on whether you’re able to attend part-time or full-time. Master’s degrees enhance your level of expertise in your field, and you can pursue many higher-level careers with the credential—or continue with your education and apply to PhD programs.

4 benefits of a PhD 

There are a number of reasons why you might want to pursue your PhD. Let’s hone in on four of them: 

1. Become an expert.

People who obtain PhDs have the highest possible education in their field. As such, they're often considered to be genuine experts in that subject matter. You may feel a tremendous amount of personal satisfaction from having achieved this level of mastery.

2. Contribute original research. 

Adding to the knowledge of a particular field is no small feat. When you write your dissertation, you will have the opportunity to make a valuable original contribution that either expands people’s understanding of a subject or brings an entirely new perspective to it.

3. Broaden your job opportunities.

Earning a PhD could qualify you to work in academia or research, but it may also increase your qualifications—or help you stand out—for jobs that do not necessarily require a PhD. Holding a PhD may convey to employers that you’re knowledgeable, hardworking, and disciplined because of what it takes to earn the degree. 

4. Increase your salary potential.

On average, people with PhDs can potentially make more than those with undergraduate degrees, depending on your profession. The median weekly earnings of a person with a PhD in the United States is $1,885 compared to $1,305 for bachelor's degree holders [ 1 ]. A doctorate can also lead to higher lifetime earnings. A bachelor’s degree graduate will earn an average of $2.2 million over their lifetime, but PhD graduates earn an average of $4 million over their lifetimes [ 2 ].

Careers that typically require a PhD

A PhD is an academic credential necessary to teach at the university level or conduct high-level research in a number of fields, such as the life and social sciences. The following careers typically require a doctorate:

Research associate

Research scientist 

Assistant professor 

Dean of students

Careers where a PhD may help you advance  

While the careers listed below generally require a master’s degree, earning your PhD may help you qualify for more advanced roles within the profession—or help you develop more specialized knowledge to succeed in your career.  

Anthropologist 

Statistician 

Political scientist 

Psychologist

What is a PhD?

• Types of Doctorates
• A Doctor of Philosophy (PhD) is the highest globally recognized postgraduate degree that higher education institutions can award.
• PhDs are awarded to candidates who undertake original and extensive research in a particular field of study.
• Full time PhD programmes typically last three to four years, whilst part time PhD programmes typically last six to seven years.
• A PhD can lead to an academia teaching role or a career in research. A PhD can also equip you with skills suitable for a wide range of jobs unrelated to your research topic or academia.

Definition of a PhD – A Doctor of Philosophy (commonly abbreviated to PhD , Ph.D or a DPhil ) is a university research degree awarded from across a broad range of academic disciplines; in most countries, it is a terminal degree, i.e. the highest academic degree possible.

PhDs differ from undergraduate and master’s degrees in that PhDs are entirely research-based rather than involving taught modules (although doctoral training centres (DTCs) offer programmes that start with a year of lecture-based teaching to help develop your research skills prior to starting your project).

In most English-speaking countries, those that complete a PhD use the title “Doctor” (typically abbreviated to Dr) in front of their names and are referred to as such within academic and/or research settings. Those that work in fields outside of academia may decide not to use the formal doctor title but use post-nominal letters (e.g. John Smith PhD); it’s unusual though for someone to use both the Doctor title and post-nominal letters in their name.

PhD vs Doctorate

A PhD and a professional doctorate are both research-based terminal degrees.

However, where a PhD focuses on original research mostly around theoretical concepts, a professional doctorate focuses on examining existing knowledge to solve real-life, practical problems.

While there is much crossover between the two, a PhD is generally better suited for an individual to wants to advance the knowledge and understanding in their field, and a professional doctorate degree is better suited to a working professional who wants to better be able to apply knowledge and understanding to their field.

What Are the Entry Requirements for a PhD?

To be accepted on to a PhD programme, students usually need to hold at least a high ( 2:1 and above ) undergraduate degree that is related to the field of research that they want to pursue. A PhD candidate may also be expected to hold a Master’s degree , however, this does not mean you must have one, as it is still possible to enrol into a PhD without a Master’s .

Self-funded courses may sometimes be more relaxed in relation to entry requirements . It may be possible to be accepted onto a self-funded PhD programme with lower grades, though these students typically demonstrate their suitability for the role through professional work experience.

Whilst a distance learning project is possible , most PhD candidates will carry out their research over at least three years based at their university, with regular contact with two academic supervisors (primary and secondary). This is particularly the case for lab-based projects, however, some PhD projects require spending time on-site away from university (e.g. at a specialist research lab or at a collaborating institution abroad).

How Long Does a PhD Take?

Typically, full-time PhDs last 3-4 years and part-time PhDs last 6-7 years. However, at the discretion of the university, the thesis writing-up period can be extended by up to four years.

Although most doctoral programmes start in September or October, they are generally much more flexible than taught-courses and can start at any time of the year.

How Much Does a PhD Cost?

Tuition fees for UK and EU students vary between £3,000 and £6,000 per year, with the average tuition fee of £4,712 per year for 2023/24 programmes.

Tuition fees increase considerably for international students, varying between £16,000 to £25,000 per year, with an average tuition fee of £19,600 per year .

Nonetheless, most students will secure PhD funding in the form of studentships, scholarships and bursaries to help pay for these fees. These funding opportunities can either be partial, which cover tuition fees only, or full, which cover both tuition fees and living expenses.

UK national students can also apply for Doctoral Loans from Student Finance England if they are unable to secure funding.

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

What Does a PhD Involve?

To be awarded a PhD, a doctoral student is required to produce a substantial body of work that adds new knowledge to their chosen field.

A PhD programme will typically involve four key stages:

Stage 1: Literature Review

The first year of a PhD involves attending regular meetings with your supervisors and carrying out a search on previously published work in your subject area. This search will be used to produce a literature review which should set the context of the project by explaining the foundation of what is currently known within the field of research, what recent developments have occurred, and where the gaps in knowledge are. In most cases, this will be an extension of your research proposal should you have produced one as part of your application. The literature review should conclude by outlining the overarching aims and objectives of the research project. This stage of setting achievable goals which are original and contribute to the field of research is an essential first step in a successful PhD.

The supervisor is the main point of contact through the duration of a PhD – but remember: they are there to mentor, not to teach, or do it for you . It will be your responsibility to plan, execute and monitor your own work as well as to identify gaps in your own knowledge and address them.

Stage 2: Research

The second year (and prehapse some of your third year) is when you work on your research. Having identified novel research questions from your review of the literature, this is where you collect your data to help answer these questions. How you do this will depend on the nature of your doctoral research: for example, you may design and run experiments in a lab alongside other PhD students or visit excavation sites in remote regions of the world. You should check in regularly with your supervisors to update them and run any ideas or issues past them.

Have the structure and chapters of your thesis in mind as you develop and tackle your research questions. Working with a view of publishing your work will be very valuable later on.

Stage 3: Write up of Thesis

The next key stage of a PhD is writing a doctoral thesis , which typically takes from anywhere between three months to one year. A thesis is a substantial body of work that describes the work and outcomes of the research over the previous two to three years. It should tell a detailed story of the PhD project – focusing on:

• The motivations for the research questions identified from the literature review.
• The methodologies used, results obtained, and a comprehensive analysis and discussion of the findings.
• A detailed discussion of the key findings with an emphasis on the original contributions made to your field of research and how this has been impactful.

There is no universal rule for the length of a PhD thesis, but general guidelines set the word count between 80,000 to 100,000 words.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available.

Stage 4: Attending the Viva

A viva voce , most commonly referred to as just a ‘ viva ‘, is an interview-style examination where the PhD student is required to engage in a critical appraisal of their work and defend their thesis against at least two examiners. The examiners will ask questions to check the PhD student has an in-depth understanding of the ideas and theories proposed in their thesis, and whether they have developed the research skills that would be expected of them.

The viva is one of the final steps in achieving a PhD, and typically lasts at least two hours, but this duration can vary depending on the examiners, the university and the PhD project itself.

Once you have done the viva – you’re on the home stretch. You will typically be asked to make some amendments to your thesis based on the examiner’s feedback. You are then ready to submit your final thesis for either:

• PhD – If you pass the requirements you will be awarded a PhD degree (most common outcome),
• MPhil – If you failed to meet requirements for a PhD, you may be downgraded to an MPhil degree (uncommon outcome),
• Fail – No award is given, typically for cases of plagiarism (extremely uncommon outcome).

What Is It Like to Undertake a PhD?

We’re often asked what it is like to undertake a PhD study. Unfortunately, this isn’t a simple answer to this question as every research project is different.

To help give insight into the life of a PhD student, we’ve interviewed PhD students at various stages of their programmes and put together a series of PhD Student Interviews . Check out the link to find out what a PhD is like and what advice they have to offer you.

What Are the Benefits of A PhD?

A PhD is the highest globally recognised postgraduate degree that higher education institutions can award. The degree, which is awarded to candidates who demonstrate original and independent research in a particular field of study, is not only invaluable in itself, but sets you up with invaluable skills and traits.

Career Opportunities

First, a PhD prepares you for a career in academia if you wish to continue in this area. This takes form as a career in the Higher Education sector, typically as a lecturer working their way to becoming a professor leading research on the subject you’ve studied and trained in.

Second, a PhD also enables the opportunity for landing a job in a research & development role outside of the academic environment. Examples of this include laboratory work for a private or third sector company, a governmental role and research for commercial and industrial applications.

Transferable Skills

Finally, in possessing a PhD degree, you can show to employers that you have vital skills that make you an asset to any company. Three examples of the transferable skills that you gain through a PhD are effective communication, time management, and report writing.

• Communication – presenting your work in written and oral forms using journal papers and podium presentations, shows your ability to share complex ideas effectively and to those with less background knowledge than you. Communication is key in the professional environment, regardless of the job.
• Time management – The ability to prioritise and organise tasks is a tremendous asset in the professional industry. A PhD holder can use their qualification to demonstrate that they are able to manage their time, arrange and follow a plan, and stick to deadlines.
• Report writing – Condensing three years of work into a thesis demonstrates your ability to filter through massive amounts of information, identify the key points, and get these points across to the reader. The ability to ‘cut out the waffle’ or ‘get to the point’ is a huge asset in the professional industry.

Aside from the above, you also get to refer to yourself as a Doctor and add fancy initials after your name!

What Can I Do After a PhD?

One of the most desirable postdoctoral fields is working within independent Research and Development (R&D) labs and new emerging companies. Both industries, especially R&D labs, have dedicated groups of PhD graduates who lead research activities, design new products and take part in crucial strategic meetings. Not only is this a stimulating line of work, but the average salaries in R&D labs and emerging start-ups are lucrative. In comparison, an undergraduate with five years of experience within their given field will, on average, likely earn less than a new PhD graduate taking on a R&D position.

It’s a common misunderstanding that PhDs only opens the door for an academic career such as university lecturers and training providers. Although obtaining a PhD opens these doors, the opportunities extend far beyond educational roles. In fact, recent data from the UK’s Higher Education Statistics Agency (HESA) indicates only 23% of PhD graduates take a position in educational roles . This low percentage is primarily because PhD graduates have a wide range of skills that make them suitable for a broad spectrum of roles. This is being seen first hand by the increasing number of PhD graduates who are entering alternative roles such as research, writing, law and investment banking.

How Do I Find a PhD?

We appreciate that finding a PhD programme to undertake can be a relatively daunting process. According to Higher Education Student Statistics , over 22,000 PhDs were awarded in 2016/17 within the United Kingdom alone. Clearly there are a huge number of PhD programmes available. This can sometimes be confusing for prospective doctorates, particularly when different programmes are advertised in different places. Often, it is difficult to know where to look or where to even start. We’ve put together a list of useful sources to find the latest PhD programmes:

• A great place to start is with our comprehensive and up-to-date database of available PhD positions .
• Assuming you are still at university, speak to an existing PhD supervisor within your department.
• Attend as many postgraduate open days as you can. Whilst there, speak to current PhD students and career advisors to get an awareness of what PhDs are on offer.
• Visit the postgraduate section of university websites and the PhD Research Council section of the UKRI website.

More than 54,000 students earned doctoral degrees in 2016, the latest year for which figures are available, a 30 percent increase since 2000, according to the  National Science Foundation . A Ph.D., also called a doctorate, is a "Doctor of Philosophy" degree, which is a misleading moniker because most Ph.D. holders are not philosophers. The term for this increasingly popular degree derives from the original meaning of the word "philosophy," which comes from the ancient Greek word  philosophia , meaning "love of wisdom."

What Is a Ph.D.?

In that sense, the term "Ph.D." is accurate, because the degree has historically been a license to teach, but it also signifies that the holder is an "authority, in full command of (a given) subject right up to the boundaries of current knowledge, and able to extend them," says  FindAPhD , an online Ph.D. database. Earning a Ph.D. requires a hefty financial and time commitment— $35,000 to $60,000  and two to eight years—as well as research, creating a thesis or dissertation, and possibly some teaching duties.

Deciding to pursue a Ph.D. can represent a major life choice. Doctoral candidates require additional schooling after completing a master's program to earn their Ph.D.: They must complete additional coursework, pass comprehensive exams , and complete an independent dissertation in their field. Once completed, though, a doctoral degree—often called a "terminal degree"—can open doors for the Ph.D.holder, especially in academia but also in business.

Core Courses and Electives

To obtain a Ph.D., you need to take a group of core courses as well as electives, totaling about 60 to 62 "hours," which are roughly the equivalent of units at the bachelor's degree level. For example, Washington State University offers a  Ph.D. in crop science . Core courses, which make up about 18 hours, include such subjects as introduction to population genetics, plant transmission genetics, and plant breeding.

Additionally, the student must make up the remaining required hours through electives. The  Harvard T.H. Chan School of Public Health  offers a doctoral degree in Biological Sciences in Public Health. After core courses such as laboratory rotations, biological sciences seminars, and core principles of biostatistics and epidemiology, the Ph.D. candidate is required to take electives in related fields such as advanced respiratory physiology, advanced respiratory physiology, and ecological and epidemiological control of parasitic diseases. Degree-granting institutions across the board want to ensure that those who earn Ph.D.s have broad knowledge in their chosen field.

Thesis or Dissertation and Research

A Ph.D. also requires students to complete a large scholarly project known as a  dissertation , a research report—usually 60-plus pages—which signifies that they are able to make significant independent contributions to their chosen field of study. Students take on the project, also known as a  doctoral thesis , after completing the core and elective coursework and passing a  comprehensive examination . Through the dissertation, the student is expected to make a new and creative contribution to a field of study and to demonstrate her expertise.

According to the Association of American Medical Colleges, for example, a strong medical dissertation relies heavily on the creation of a specific hypothesis that can be either disproved or supported by data collected through independent student research. Further, it must also contain several key elements starting with an introduction to the problem statement, conceptual framework, and research question as well as references to literature already published on the topic. Students must show that the  dissertation  is relevant, provides new insight into the chosen field, and is a topic that they can research independently.

Financial Aid and Teaching

There are several ways to pay for a doctoral degree: scholarships, grants, fellowships, and government loans, as well as teaching.  GoGrad , a graduate school information website, provides such examples as the:

• Science, Mathematics, and Research for Transformation (SMART) Scholarship for Service Program, which provides full tuition and an annual stipend of $25,000 to $38,000.
• National Defense Science and Engineering Graduate Fellowship, a three-year graduate fellowship that is designed to support doctoral students across 15 engineering disciplines
• National Science Foundation Graduate Research Fellowship Program, a three-year program that provides an annual stipend of $34,000 and a $12,000 cost-of-education allowance for tuition and fees

As it does for bachelor's and master's degrees, the federal government also offers several  loan programs  to help students finance their Ph.D. studies. You generally apply for these loans by filling out the free application for federal student aid ( FAFSA ). Students planning to go into teaching after obtaining their doctoral degrees often also supplement their income by teaching undergraduate classes at the schools where they are studying. The University of California, Riverside, for example, offers a "teaching award"—essentially a stipend applied toward tuition costs—for Ph.D. candidates in English who teach undergraduate, beginning-level, English courses

Jobs and Opportunities for Ph.D. Holders

Education accounts for a large percentage doctoral awards, with elementary education, curriculum and instruction, educational leadership and administration, special education, and counselor education/ school counseling topping the list. Most universities in the United States require a Ph.D. for candidates who seek teaching positions, regardless of the department.

Many Ph.D. candidates seek the degree, however, to boost their current salaries. For example, a health, sports, and fitness educator at a community college would realize a bump in annual pay for obtaining a Ph.D. The same holds for educational administrators. Most such positions require only a master's degree, but obtaining a Ph.D. generally leads to an annual stipend that school districts add to the annual salary. That same health and fitness instructor at a community college could also move on from a teaching position and become a dean at a community college—a position that requires a Ph.D.—boosting his pay to  $120,000 to $160,000  a year or more.

So, the opportunities for a doctoral degree holder are wide and varied, but the cost and commitment required are significant. Most experts say you should know your future career plans before you make the commitment. If you know what you want to get out of the degree, then the years of required study and sleepless nights may well be worth the investment.

What’s the Difference Between a Ph.D. and a Doctorate?

• July 8, 2024

Table of Contents

Research (academic), applied (professional), what is a ph.d., is a ph.d. higher than a professional doctorate, doctoral study vs. dissertation, who is it for, what do you learn in each, can a ph.d. be called a doctor, the bottom line, what’s the difference between a ph.d. and a doctorate, are ph.d. and doctorate terms interchangeable, what are examples of other doctorate degrees besides a ph.d., do ph.d. and doctorate programs have different structures or requirements, which is more academic-focused: ph.d. or other doctorate degrees, can ph.d. holders and other doctorate degree holders use the title “dr.”.

The terms Ph.D. and Doctorate are often used interchangeably when considering advanced degrees in academia. Both degrees involve rigorous academic study and research, but their focus, duration, and requirements differ. Hence, these significant differences between the two are worth understanding before deciding which path to pursue.

In this article, we will explore the difference between a Ph.D. and a doctorate, including their definitions, the types of programs they are offered in, and the career opportunities they lead to.

What Is a Doctorate?

A doctorate degree is the highest level of academic degree that can be awarded by a university. It typically requires a minimum of three to five years of advanced study and research beyond a bachelor’s or master’s degree .

Doctoral programs are designed to prepare individuals for advanced careers in academia, research, or other professional fields. There are two main types of doctorates: Research (Academic) and Applied (Professional). Let’s talk about each in more detail.

A research doctorate, also known as an academic doctorate, is a type of doctoral degree focused on original research and advancing knowledge in a specific academic field. These programs require students to take advanced coursework in their field and complete original research contributing to the body of knowledge in their study area.

The research component is typically the program’s centerpiece, and students are expected to produce a dissertation or thesis that represents a significant contribution to their field of study. A research doctorate is highly valued in academia, and graduates often pursue careers as professors, researchers, or scholars in their field.

While a significant time commitment and dedication are required, they provide individuals with the skills and knowledge necessary to make contributions to their field and advance their careers in academia. Examples of research doctorates include the Doctor of Philosophy (Ph.D.), Doctor of Science (D.Sc.), and Doctor of Education (Ed.D.) , among others.

An applied doctorate, or professional doctorate, is a type of doctoral degree that focuses on applying knowledge and skills in a specific profession or industry. These programs emphasize the practical application of research and theories to solve real-world problems in their field.

The curriculum includes coursework designed to enhance students’ professional skills, including leadership , management, or organizational behavior. An applied doctorate program’s capstone project or dissertation addresses a real-world problem or issue within the student’s profession or industry. The research is conducted in collaboration with professionals in the field.

While applied doctorate programs require a significant time commitment and dedication to a specific profession, they provide individuals with the knowledge and skills necessary to become experts in their field and make a great impact. Graduates of such programs are well-prepared to take on leadership roles in their profession. The degree can lead to higher salaries and career advancement.

Examples of applied doctorates include the Doctor of Education (Ed.D.), Doctor of Business Administration (DBA), and Doctor of Psychology (Psy.D.), among others.

Students who have completed advanced studies in a particular academic field and contributed original research to that field are awarded a Ph.D., also known as a Doctor of Philosophy. Ph.D. programs are geared toward developing independent scholars who can conduct original research and advance knowledge in their chosen fields.

The coursework of a Ph.D. program involves advanced studies in the student’s area of interest, coupled with a significant research component. Students must produce a dissertation or thesis that adds to the existing body of knowledge in their field of study.

Ph.D. programs generally require multiple years to complete and lead to opportunities for graduates to work as professors, scholars, or researchers within their field of specialization.

While Ph.D. degrees are commonly associated with academic careers, they can also offer advantages for graduates seeking positions in government or industry, as they demonstrate expertise in a specific area and an aptitude for original research.

Comparing a Ph.D. to a professional doctorate is difficult, as both degrees have distinct characteristics and are designed for different purposes.

A Ph.D. is primarily a research-focused degree focused on producing independent scholars who can conduct original research and contribute to the advancement of knowledge in a particular field.

On the other hand, a professional doctorate focuses on the application of knowledge and skills in a specific profession or industry. These programs typically emphasize the practical application of research and theories to solve real-world problems in their field.

Graduates of professional doctorate programs are well-prepared to take on leadership roles in their profession, and the degree can lead to career advancement and higher salaries.

So, in terms of purpose and focus, Ph.D. and professional doctorate degrees are different. It’s not a matter of one being higher than the other, but rather, it depends on an individual’s career goals and aspirations. Both degrees are considered terminal degrees, meaning they represent the highest level of academic achievement in their respective fields.

The Difference Between a Ph.D. and a Doctorate

Understanding the differences between a Ph.D. and a professional doctorate can help you make an informed decision about which program is right for you and your career goals. And while both types of degrees require extensive study and research, there are significant differences between the two.

One of the key differences between a Ph.D. and a professional doctorate is the focus of the doctoral study. Ph.D. programs typically focus on producing independent scholars who can conduct original research and advance knowledge in their chosen field.

In contrast, professional doctorate programs emphasize the practical application of research and theories to solve real-world problems in their field.

While both degrees require extensive research, Ph.D. programs often require a significant original contribution to the field in the form of a dissertation, while professional doctorate programs typically require a capstone project or applied research project that demonstrates the student’s ability to apply their knowledge to a real-world problem.

Ph.D. programs are geared toward individuals interested in pursuing an academic career, such as becoming a professor or researcher. These programs prepare students for a life of scholarship and original research.

On the contrary, professional doctorate programs are geared toward professionals already working in a specific profession or industry and wanting to advance their careers through further education. These programs provide students with the knowledge and skills needed to take on leadership roles in their profession or industry.

The content of the curriculum in Ph.D. and professional doctorate programs differs significantly. Ph.D. programs aim to give students extensive knowledge of their field of study and equip them with the skills to conduct original research.

On the other hand, professional doctorate programs have a practical focus, with students taking courses that prepare them for leadership positions in their respective professions or industry, including management, ethics , and professional communication.

The title “Doctor” is used to refer to someone who has earned a doctoral degree, whether it is a Ph.D. or a professional doctorate. In academic and professional settings, it is common for individuals with a Ph.D. to be referred to as “Dr.” along with their name, just as someone with a professional doctorate would be.

However, it’s important to note that the title “Doctor” does not necessarily indicate that the person is a medical doctor or a physician. Additionally, it is worth noting that different countries and cultures have different conventions for how the title “Doctor” is used, so it’s always a good idea to check local customs and norms to ensure proper usage.

The decision to pursue a Ph.D. or a professional doctorate ultimately depends on your individual career goals and aspirations. Both degrees are highly respected and can lead to exciting and fulfilling careers.

Remember, the pursuit of advanced education is a challenging but rewarding journey that leads toward new opportunities, personal growth, and the chance to make a positive impact in your field.
