Academic degree

An academic degree is a qualification awarded on successful completion of a course of study in higher education, normally at a college or university. These institutions commonly offer degrees at various levels, typically including bachelor's, master’s and doctorates, often alongside other academic certificates, and professional degrees. The most common undergraduate degree is the bachelor's degree, although in some countries lower qualifications are titled degrees (e.g. associate degrees in the US or foundation degrees in the UK) while in others a higher-level first degree is more usual.

The modern academic system of academic degrees evolved and expanded in the medieval university, spreading everywhere across the globe as the institution did:

The doctorate (Latin: doceo “I teach”) appeared in medieval Europe as a license to teach (Latin: licentia docendi) at a medieval university. Its roots can be traced to the early church when the term "doctor" referred to the Apostles, church fathers and other Christian authorities who taught and interpreted the Bible. The right to grant a licentia docendi was originally reserved to the church which required the applicant to pass a test, to take oath of allegiance and pay a fee. The Third Council of the Lateran of 1179 guaranteed the access – now largely free of charge – of all able applicants, who were, however, still tested for aptitude by the ecclesiastic scholastic. This right remained a bone of contention between the church authorities and the slowly emancipating universities, but was granted by the Pope to the University of Paris in 1231 where it became a universal license to teach (licentia ubique docendi). However, while the licentia continued to hold a higher prestige than the bachelor's degree (Baccalaureus), it was ultimately reduced to an intermediate step to the Magister and doctorate, both of which now became the exclusive qualification for teaching.
