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 cases, it may also be the name of a second graduate degree, such as the Bachelor of Laws (LL.B.), Bachelor of Education (B.Ed.), Bachelor of Civil Law (B.C.L.), Bachelor of Music (B.Mus.), Bachelor of Philosophy (B.Phil.), or Bachelor of Sacred Theology (B.S.Th.) degrees, which in some countries are only offered after a first graduate/bachelor's degree.
