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)
Bachelor of Arts
In the United Kingdom (excluding Scotland) and Ireland, the first degree course normally lasts three years, but nomenclature varies: 19th-century and later universities usually distinguish between arts and sciences subjects by awarding either a B.A. or B.Sc. degree. However, some older or ancient universities, such as Oxford, Cambridge and Dublin traditionally award B.A.s to undergraduates having completed the final examinations, e.g. Part II Tripos (Cambridge), Final Honour Schools (Oxford), Moderatorship (Dublin), in most subjects including the sciences. Some new plate glass universities established in the 1960s, such as York and Lancaster originally followed the practice of Oxford and Cambridge by awarding B.A.s in all subjects, but have since changed to awarding B.Sc. degrees in science subjects. At Oxford, Cambridge and Dublin the degree of M.A. can be claimed, usually 21 terms after matriculation. For many centuries, the bachelor's degree was an intermediate step and was awarded for much of the work carried out in later times at secondary schools. The names of the final secondary school exams in France and Spain (and increasingly in the UK—the International Baccalaureate) come from this: le Baccalauréat and el "Bachillerato", respectively.
