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).
Professional degree
A professional degree, formerly known in the US as a first professional degree, is a degree that prepares someone to work in a particular profession, often meeting the academic requirements for licensure or accreditation. Professional degrees may be either graduate or undergraduate entry, depending on the profession concerned and the country, and may be classified as bachelor's, master's or doctoral degrees. For a variety of reasons, professional degrees may bear the name of a different level of qualification from their classification in qualifications frameworks, e.g. some UK professional degrees are named bachelor's but are at master's level, while some Australian and Canadian professional degrees have the name "doctor" but are classified as master's or bachelor's degrees.
