In Western universities, a Bachelor of Divinity or Baccalaureate in Divinity (BD or BDiv; ) is a postgraduate academic degree awarded for a course taken in the study of divinity or related disciplines, such as theology or, rarely, religious studies. At the University of Cambridge, the Bachelor of Divinity degree is considered senior to the university's PhD degree. In the Catholic universities the Bachelor of Sacred Theology (STB) is often called the Baccalaureate in Divinity (BD) and is treated as a postgraduate qualification. United Kingdom Current examples of where the BD degree is taught in the United Kingdom are: the University of St Andrews (where entrants must hold a degree in another discipline); Queen's University Belfast; the University of Aberdeen; the University of Edinburgh; and the University of Glasgow. At the University of Cambridge and previously at the University of Oxford, the BD is a postgraduate qualification, and applicants must have already completed an undergraduate degree before becoming a candidate for the degree. The same principle applied at Oxford where the degree was closed to new registrations in 2005; BDs continue to be awarded to those registered before 2005. Registration for Cambridge's BD is only open to senior graduates of that university. The BD at Cambridge is the highest ranking bachelor's degree, and it is so senior that it outranks the PhD. It requires a significant contribution to knowledge in the area of Christian theology, and is awarded based on published work, dissertation, or a combination of both. The University of Durham BD was of a similar nature, and available to graduates of seven years' standing. It was awarded on the basis of published work of a similar extent to a PhD – the usual basis for the award was a book. It is no longer awarded. St Mary's College at the University of St Andrews – where the main undergraduate award is the MTheol (Master of Theology) – offers the BD following a three-year course of study for graduates in other disciplines. Heythrop College, a constituent college of the University of London, offered a BD course through the University of London International Programmes, which was not restricted to only members of the university. Due to the closure of Heythrop College January 2019 the University of London itself provides academic direction for the Divinity programme as it continues to be offered through the International Programme.
