Academic degree
Doctoral degrees or doctorates, such as the Doctor of Philosophy degree (PhD or DPhil) or Doctor of Education (EdD or DEd) are awarded following a programme of original research that contributes new knowledge within the context of the student's discipline. Doctoral degrees usually take three years full-time. Therefore, in the UK it may only take seven years to progress from undergraduate to doctoral level – in some cases six, since having a Master's is not always a precondition for embarking on a doctoral degree. This contrasts with nine years in the United States, reflecting differences in the educational systems.
Master of Philosophy
Although most American universities do not award the M.Phil., a few award it under certain circumstances. At those institutions (including Yale University, Columbia University, Pardee RAND Graduate School, George Washington University, Rutgers University, The New School for Social Research and the CUNY Graduate Center), the degree is awarded to Ph.D. candidates when they complete their required coursework and qualifying examinations prior to the completion and defense of a doctoral dissertation. This recognizes achievement beyond the Master of Arts and Master of Science degrees conferred after 1–3 years of graduate study and formalizes the more colloquial "All But Dissertation" status; as such, defense of a dissertation proposal is sometimes required for conferral.
