Common room (university)

A common room is a group that students, and sometimes academic staff, are organised into at some universities, especially in the United Kingdom. These groups are usually part of a smaller section of the university, such as a college or hall of residence, and they work alongside the university-wide students' union.

Common rooms represent their members, run services such as laundry and recreation, and give students chances to socialise. Classically, there are three kinds. The junior common room (JCR) is for undergraduate students. The middle common room (MCR) is for postgraduate students in colleges that have many of them. The senior common room (SCR) is for academic members of the college.

Common rooms are especially found at collegiate universities such as Oxford, Cambridge, Durham, York and Lancaster. They can also be found at non-collegiate universities, though there it is often only the JCR, and these are usually linked to halls of residence.

A key difference between colleges and halls is that students stay members of a college even when they do not live there. This means college JCRs serve all of the college's members, while hall JCRs serve only the residents of that hall.

Organisations known as common rooms are also found in universities in Australia, Ghana, Ireland, Singapore and the US. The term can also refer to an actual common room set aside for these groups. At the University of Cambridge, the term "combination room" is used as well.

United Kingdom

Common rooms are found at almost all collegiate universities and in halls at a few non-collegiate universities. Student common rooms may be classified as students' unions under the Education Act 1994. Until the Charities Act 2006, common rooms were exempt charities. Under that act and the Charities Act 2011, they must now register with the Charity Commission if their income is £100,000 a year or more. As of August 2025, eight common rooms were registered, all from colleges of Durham University. Like other students' unions, common rooms may appoint sabbatical officers. This is common at Durham but rare elsewhere. College sizes vary, so common room sizes vary too. The median Durham college had 1385 students in 2024/25, while the median Oxford college had 665. Common rooms at Oxford, Cambridge and Durham are independent of their central students' unions. Those unions still communicate with them through the executive at Roehampton, formal representation in the Cambridge Students' Union council, the Durham Students' Union Assembly, the Lancaster University Students' Union assembly, or regular meetings with Oxford University Student Union (OUSU).

Most junior common rooms (JCRs) are led by a JCR president, elected by JCR members along with other officers who form the JCR committee. Some colleges have used the title "senior man", a reminder that they were founded as male-only institutions. Hatfield College, Durham still uses it. University College, Durham has allowed "senior student", "senior man" or "senior woman" since 2015, and Trinity College, Melbourne uses "senior student". St Chad's College, Durham changed to "JCR president" in 2018, and Van Mildert College, Durham also used "senior man" until at least 1998. At the University of Oxford, early JCRs dating back to the 17th century were private clubs for richer students, known for drinking. After reforms in the mid-19th century, Corpus Christi disbanded its JCR in 1852, and New College moved to dissolve its JCR in 1868. Instead, the JCR came under college oversight and became a society for all undergraduates. By the end of the 19th century, similar arrangements existed at almost all Oxford colleges. Middle common rooms (MCRs) for graduates were set up in the 1960s, when postgraduate numbers grew. At Lancaster, each undergraduate college has a JCR, and the graduate college has a postgraduate board. At non-collegiate universities, such as Bristol, Leeds, Nottingham and Reading, many hall JCRs had mostly disappeared by 2025 in favour of professional residential life teams.

Other countries

The University of New England has a residential college system, and its colleges have JCRs that organise social events. The University of Ghana has JCRs that represent students from its undergraduate halls and from the business school. At Trinity College, Trinity Hall, Dublin has the only JCR. It represents students who live at the hall and mainly provides services to them, while Trinity College Dublin Students' Union is the main representative body for student members of the college. Trinity Hall also has an SCR, made up of the warden, deputy warden and assistant wardens.

The National University of Singapore has elected JCR committees in its halls of residence, as well as SCR committees. The JCR and SCR work together to plan events. The JCR also represents students in its hall to the university administration, the university-wide students' union, and the JCRs in other halls. At Harvard College, each house has an SCR made up of academics, alumni and others from the local area. The student groups in the houses are known as "HoCo" (short for "house committee"), and the term "junior common room" refers to an actual room.
