Types of PhD

When is a 'PhD' not a PhD? When it's a DPhil, DBA, EdD or other type of doctorate.

The traditional PhD (or 'Doctor of Philosophy') is the best-known advanced research qualification, but several other varieties of doctoral degree exist. Some of these are academic qualifications in specific subject areas. Others are professional doctorates with a slightly different format.

The way in which candidates study for a PhD is also becoming more varied, with the opportunity to research part time or even pursue a joint doctorate, awarded by more than one university.

But there's no need to be confused. This page explains and compares the options available to you.

The MPhil

An MPhil (or 'Master of Philosophy') isn't a full PhD. But these less ambitious projects still provide excellent research experience.

You can more about some of these degree types in our guide to different varieties of doctorate.

Understanding this table

The doctorates in the above table are divided into different types, as follows:

  • Academic doctorates (such as the standard PhD) are usually awarded for original research and scholarship in traditional academic subjects. They can prepare a student for various careers, but their main focus is on broadening theoretical understanding of a subject, rather than improving professional practice.
  • Professional doctorates are awarded for work that contributes directly to knowledge or practice in a specific vocational field. They still involve original research and analysis, but also incorporate more practical training and instruction. Candidates may require appropriate experience.
  • Higher doctorates are usually awarded later in a person's career, as a means of recognising esteemed researchers or practitioners. Students do not normally enrol for these doctorates as traditional university degrees.
  • Honorary doctorates are awarded to celebrate an individual's achievements. They do not require any specific track record of academic or professional work and can be granted at the discretion of a university. Students do not enrol for these doctorates.

As a prospective postgraduate student, you only really need to concern yourself with academic or professional research degrees.

We've included higher and honorary doctorates here in order to try and prevent them being confused with more 'conventional' PhDs (and to give you some inspiration for later in your career!).
