Durham University there is no formal teaching at Durham colleges (with the exception of Cranmer Hall theological college within St John's), although colleges are active in research. The colleges dominate the residential, social, sporting, and pastoral functions within the university, and there is heavy student involvement in their operation. Formal dinners (known as "formals") are held at every college; gowns are worn to these events at just over half of the colleges. Gowns are not worn for formals at Collingwood, St Aidan's, St Cuthbert's, Hild Bede, Van Mildert, Stephenson or Ustinov. There is a great deal of intercollegiate rivalry, particularly in rowing
