Bachelor of Philosophy
The B.Phil.'s earliest form is as a University of Oxford graduate degree, first awarded in 1682. Originally, Oxford named its pre-doctoral graduate degrees the Bachelor of Philosophy (B.Phil.) (a two-year degree, partly taught and partly by research) and the Bachelor of Letters (B.Litt.) (a two-year research degree). After complaints, especially from overseas students, that this naming convention often meant that graduate degrees were not being recognised as such, the University renamed them Master of Philosophy (M.Phil.) and Master of Letters (M.Litt.). However, the Philosophy Faculty (then a Sub-Faculty) argued that its B.Phil. degree had become so well known and respected in the philosophical world that it would be confusing to change the name. In philosophy, therefore, the degree continues to be called the B.Phil. Those who pass the degree are given the choice of taking a B.Phil. or an M.Phil.; few if any choose the latter. (Note that Oxford also offers a number of other graduate degrees labeled as baccalaureate degrees: the law faculty's BCL; and the music faculty's B.Mus)
National Institutes of Technology
The NITs also offer the Doctor of Philosophy degree (PhD) as part of their doctoral education programme. In it, the candidates are given a topic of academic interest by the professor or have to work on a consultancy project given by the industries. The duration of the program is usually unspecified and depends on the specific discipline. PhD candidates have to submit a dissertation as well as provide an oral defence for their thesis. Teaching Assistantships (TA) and Research Assistantships (RA) are often provided. The NITs, along with IITs and IISc, account for nearly 80% of all engineering PhDs in India.
