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)
Diplom
The duration of the "Diplom" degree programmes differed depending on subject and university. An official average duration ("Regelstudienzeit") was set by law in each German state, usually being four years for a "Diplom (FH)" and 4, 4.5 or 5 years for a "Diplom / Diplom (Univ.)". In exceptional cases, universities were allowed to set longer average durations for certain subjects (HGRP1995 § 26 (3), NHG2007 § 6 (3), HmbHG2001 §53 (3)). However, due to the curriculum set by most universities in Germany, the 4, 4.5 or 5 years for a "Diplom / Diplom (Univ.)" were often exceeded.
Although being a first degree, because of its actual duration, the "Diplom / Diplom (Univ.)" was and is in Germany not considered as an equivalent to a bachelor's but rather to a master's degree, as also expressed by the equivalent ECTS credits for the "Diplom / Diplom (Univ.)".
