A Doctor of Philosophy (PhD or DPhil; Latin: philosophiae doctor or doctor in philosophia)[1] is a terminal degree, that usually denotes the highest level of academic achievement in a given discipline and is awarded following a course of graduate study and original research. The name of the degree is most often abbreviated PhD (or, at times, as Ph.D. in North America), pronounced as three separate letters (/ˌpiːeɪtʃˈdiː/ PEE-aych-DEE).[2][3][4]
The abbreviation DPhil, for "Doctor of Philosophy",[5] is used by the University of Oxford.[6] Additionally, it was formerly used by the University of York and University of Sussex in the United Kingdom.[7]
PhDs are awarded for programs across the whole breadth of academic fields. Since it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a dissertation, and, in some cases, defend their work before a panel of other experts in the field. In many fields, the completion of a PhD is typically required for employment as a university professor, researcher, or scientist.[8]
Very few persons had received even an honorary DLitt by 1916 when the Reverend E. M. Walker, Senior Tutor of Queen's, proposed, as the Oxford Magazine put it, that the University 'should divert the stream' of American aspirants to the German universities' degree of philosophiae doctor by opening the DLitt to persons offering a suitable dissertation nine terms after graduation. Apart from a successful move led by Sidney Ball, philosophy tutor at chapter-url=https://books.google.com/books?id=OP5ePl7i5EIC&pg=PA125 |St John's, to distinguish the proposed arrangement from both the DLitt and the German PhD by adopting the English title "doctor of philosophy" (DPhil), the scheme meet with little opposition
A DPhil is the Oxford term for a PhD.
