The system of academic degrees in the University of Oxford can be confusing to those not familiar with it. This is not merely because many degree titles date from the Middle Ages, but also because many changes have been haphazardly introduced in recent years. For example, the (medieval) BD, BM, BCL, etc., are postgraduate degrees, while the (modern) MPhys, MEng, etc., are undergraduate degrees.
In postnominals, "University of Oxford" is normally abbreviated "Oxon.", which is short for (Academia) Oxoniensis: e.g. MA (Oxon.), although within the university itself the abbreviation "Oxf" can be used.
The Bachelor's degree is awarded soon after the end of the degree course (three or four years after matriculation). Until recently, all undergraduates studied for the degree of Bachelor of Arts. The BFA was introduced in 1978. Holders of the degrees of BA and BFA both proceed in time to the degree of Master of Arts (MA). Note that the BA is still awarded even for some science courses, such as the three-year Physics degree which also still adheres to the traditional degree classification structure, with only 30% of candidates being awarded an upper second class honours or above. The degree of Bachelor of Science (BSc) has never been awarded as an undergraduate degree at Oxford; it used to be awarded as a graduate qualification, however.
The BTh is awarded primarily to students of the various theological colleges and halls enjoying some sort of associate status with the university, such as Wycliffe Hall, St Stephen's House, Ripon College Cuddesdon and the former Westminster College, Oxford. Usually, these students are candidates for the ordained ministry of one of the mainstream Christian denominations, but may be drawn from any faith background or none at the discretion of the College or Hall. It should not be confused with the degree of bachelor of divinity (BD), which is a postgraduate degree.
The BEd was formerly awarded to students residing at Westminster College, Culham College of Education, the Lady Spencer Churchill College of Education, and Milton Keynes College of Education (formerly the North Buckinghamshire College of Education) who read concurrently at the university.
