The MCR Committee is elected in the Easter term each year, and new officers take up their posts at the end of that term (just before the summer holidays). Elections for Freshers Rep and the Postgraduate Representative to College Council are held during the Michaelmas term.
The Committee members are your first port of call for various different aspects of postgraduate life; they are always happy to help if you contact them.
Meetings happen every fortnight during term and less frequently during the vacations; see the Meetings page for more information. Minutes of the Committee meetings are published on that page as soon as possible after the meeting.
The MCR itself is governed by a constitution.
