GED PhD

Doctor of Philosophy, abbreviated PhD (also Ph.D.), for the Latin philosophiæ doctor, meaning "teacher of philosophy", or alternatively, DPhil, Dr. phil. or similar, for the equivalent doctor philosophiæ, is an advanced academic degree awarded by universities. In many English-speaking countries, the PhD is the highest degree one can earn and applies to graduates in a wide array of disciplines in the sciences and humanities. The PhD or equivalent has become a requirement for a career as a university professor or researcher in most fields.

The detailed requirements for award of a PhD degree vary throughout the world. In some countries (the US, Canada, Denmark, for example), most universities require coursework in addition to research for PhD degrees. In many other countries (especially those with a greater degree of specialization at the undergraduate level, such as the UK) there is generally no such condition. It is not uncommon, however, for individual universities or departments to specify additional 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 those 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. 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 PhD degree for their research doctorates (see, for example, the Bologna Process).

The doctorate was extended to philosophy in the European universities in the Middle Ages which generally placed all academic disciplines outside the professional fields of theology, medicine and law under the broad heading of "philosophy" (or "natural philosophy" when referring to science). According to Wellington, Bathmaker, Hunt, McCullough and Sikes (2005), the first Doctor of Philosophy degree was awarded in Paris in 1150, but not until the early nineteenth century, following the practice in Germany, did the degree acquire its modern status as an advanced research degree. As Wellington et al. explain, prior to the nineteenth century professional doctoral degrees could only be awarded in theology (ThD), law (JD), or medicine (MD). In 1861, Yale University adopted the German practice (first introduced in the 19^th century at the Berlin University) of granting the degree to younger students who had completed a prescribed course of graduate study and successfully defended a thesis/dissertation containing original research in science or in the humanities.

From the United States the degree spread to Canada in 1900, and then to the United Kingdom in 1917. This displaced the existing Doctor of Philosophy degree in some universities; for instance, the DPhil (higher doctorate in the faculty of philosophy) at the University of St Andrews was discontinued and replaced with the PhD (research doctorate). Oxford retained the DPhil abbreviation for their research degrees. Some newer UK universities, for example Buckingham (est. 1976), Sussex (est. 1961), and, until a few years ago, York (est. 1963), chose to adopt the DPhil, as did some universities in New Zealand.
