Colleges of Durham University mixed in 2005 with the admittance of male undergraduates. One college, Ustinov, admits only postgraduates. Durham operates a collegiate structure similar to that of the University of Oxford and the University of Cambridge, in that all colleges at Durham, being constituent colleges of a "recognised body", are "listed bodies" in the Education (Listed Bodies) (England) Order 2013 made under the Education Reform Act 1988. The "recognised body" in this case is Durham University. Though most of the Durham colleges are governed and owned directly by the University itself, and so do not enjoy the independence of colleges at Oxford and
University of London ranging from admissions to funding, the constituent colleges operate on an independent basis, with many awarding their own degrees whilst remaining in the federal university. The largest colleges by enrolment as of 2016/17 are UCL, King's College London, City, Queen Mary, Birkbeck, the London School of Economics, Royal Holloway, and Goldsmiths, each of which has over 9,000 students. Smaller, more specialist, colleges are the School of Oriental and African Studies (SOAS), St George's (medicine), the Royal Veterinary College, London Business School, the London School of Hygiene and Tropical Medicine, the Royal Central School of Speech and Drama, the Royal Academy
