Bachelor's degree
Until the 19th century, a bachelor's degree represented the first degree in a particular faculty, with Arts representing undergraduate study, thus the Bachelor of Civil Law (BCL) at Oxford and the Bachelor of Laws (LLB) at Cambridge, for example, were postgraduate degrees. Vestiges of this system still remain in the ancient universities, with Oxford and Cambridge awarding BAs for undergraduate degrees in both arts and sciences (although both award undergraduate BTh degrees through associated theological colleges, and Oxford awards BFA degrees in addition to the BA) and defining other bachelor's degrees (e.g. BPhil, BCL) as postgraduate awards equivalent to master's degrees, although many postgraduate bachelor's degrees have now been replaced by equivalent master's degrees (e.g. LLM for the LLB at Cambridge and MSc for the BSc at Oxford). The same historical usage of indicating an undergraduate degree by it being in the faculty of arts rather than being a bachelor's degree gives rise to the Oxbridge MA and the Scottish MA).
Bachelor's degree
The Bachelor of Education degree (B.Ed.) is a four-year undergraduate professional degree offered by many American colleges and universities for those preparing to be licensed as teachers. Variants include the B.Ed., B.A.Ed, B.A.T. (Bachelor of Arts for Teaching), and B.S.T. degrees. Preparation for the M.S. in education, this degree is most often received by those interested in early childhood, elementary level, and special education, or by those planning to be school administrators. Secondary level teachers often major in their subject area instead (i.e., history, chemistry, or mathematics), with a minor in education. Some states require elementary teachers to choose a subject major as well, and minor in education.
