Bachelor's degree
A bachelor's degree (from Middle Latin "baccalaureus") or baccalaureate (from Modern Latin "baccalaureatus") is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to seven years (depending on institution and academic discipline). In some institutions and educational systems, some bachelor's degrees can only be taken as graduate or postgraduate degrees after a first degree has been completed. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately), although some qualifications titled bachelor's degrees may be at other levels (e.g. MBBS) and some qualifications with non-bachelor's titles may be classified as bachelor's degrees (e.g. the Scottish MA and Canadian MD).
British degree abbreviations
Conversely, some bachelor's degrees in the "higher faculties" at the older universities in the UK (e.g. those other than arts at Oxford and Cambridge) are postgraduate qualifications (e.g. the BCL and BMus at Oxford). Many have been changed to the corresponding master's degree (e.g. BSc is now MSc at Oxford), but only within the last generation. The BD (Bachelor of Divinity) remains a higher degree at some universities (e.g. Oxford, Cambridge, St Andrews and, until recently, Durham) but is an undergraduate degree at most (e.g. London, Edinburgh, Aberdeen and Glasgow).
