All colleges have equal status, and each has its own constitution. The day-to-day running of the colleges is managed by an elected committee of staff and student members chaired by the college's Provost. Most colleges have a Junior Common Room for undergraduate students, which is managed by the elected Junior Common Room Committee, and a Graduate Common Room for postgraduate students, as well as a Senior Common Room, which is managed by elected representatives of the college's academic and administrative members.
