A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: philosophiae doctor or doctor philosophiae) 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).[1][2][3]

The abbreviation DPhil, from the English "Doctor of Philosophy",[4] is used by a small number of British universities,[5] including the University of Oxford and formerly the University of York and University of Sussex in the United Kingdom.[6]
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. The completion of a PhD is typically required for employment as a university professor, researcher, or scientist in many fields.[7]
