Doctor of Philosophy, abbreviated Ph.D. or PhD for the Latin philosophiæ doctor, meaning "teacher of philosophy", (or, more rarely, D.Phil., for the equivalent doctor philosophiæ) is an advanced academic degree awarded by universities. In many, but not all countries in the English-speaking world, it has become the highest degree one can earn (but see also the higher doctorates awarded by universities in the UK, Ireland and some Commonwealth countries) and applies to graduates in a wide array of disciplines in the sciences and humanities. The Ph.D. has become a requirement for a career as a university professor or researcher in most fields.
The detailed requirements for award of a Ph.D. degree vary throughout the world; however, there are a number of common factors. In some countries (the US, Canada, Denmark, for example), most universities require coursework for Ph.D. degrees. In many other countries (especially those with a greater degree of specialization at the undergraduate level, such as the UK) there is no such condition in general. It is not uncommon, however, for individual universities or departments to specify analogous requirements for students not already in possession of a master's degree.
In countries requiring coursework, there is usually a prescribed minimum amount of study — typically two to three years full time, or a set number of credit hours — which must take place before submission of a thesis. This requirement is usually waived for academic staff submitting a portfolio of peer-reviewed published work. The candidate may also be required to successfully complete a certain number of additional, advanced courses relevant to his or her area of specialization.
A candidate must submit a thesis or dissertation consisting of a suitable body of original academic research, which is in principle worthy of publication in a peer-refereed context.[1] In many countries a candidate must defend this work before a panel of expert examiners appointed by the university; in other countries, the dissertation is examined by a panel of expert examiners who stipulate whether the dissertation is in principle passable and the issues that need to be addressed before the dissertation can be passed.
Universities in the non-English-speaking world have begun adopting similar standards to those of the Anglophone Ph.D. degree for their research doctorates (see, for example, Bologna Process).
