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.

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.
