Colleges of the University of Oxford
The University of Oxford has 38 Colleges and 6 Permanent Private Halls (PPHs) of religious foundation. Colleges and PPHs are autonomous self-governing corporations within the university, and all teaching staff and students studying for a degree at the university must belong to one of the colleges or PPHs. These colleges are not only houses of residence, but have substantial responsibility for student teaching. Generally tutorials (one of the main methods of teaching in Oxford) and classes are the responsibility of colleges, while lectures, examinations, laboratories and the central library are run by the university. Most colleges take both graduates and undergraduates, but several are for graduates only.
Undergraduate and graduate students may name preferred colleges in their applications. For undergraduate students, an increasing number of departments practise reallocation to ensure that the ratios between potential students and subject places available at each college are as uniform as possible. For the Department of Physics, reallocation is done on a random basis after a shortlist of candidates is drawn upon and before candidates are invited for interviews at the university.
For graduate students, many colleges express a preference for candidates who plan to undertake research in an area of interest of one of its fellows. St Hugh's College, for example, states that it accepts graduate students in most subjects, principally those in the fields of interest of the Fellows of the college.
A typical college consists of a hall for dining, a chapel, a library, a college bar, senior, middle (postgraduate) and junior common rooms, rooms for 200–400 undergraduates as well as lodgings for the head of the college and other dons. College buildings range from the medieval to modern buildings, but most are made up of interlinked quadrangles (courtyards), with a lodge controlling entry from the outside.
2008 saw the first modern merger of colleges, with Green College and Templeton College merging to form Green Templeton College. This reduced the number of Colleges of the University from 39 to 38. The number of PPHs also reduced in 2008, when Greyfriars closed down.
The University of Oxford's collegiate system arose because the university came into existence through the gradual agglomeration of independent institutions in the city of Oxford.
The first academic houses were monastic halls. Of the dozens that were established in Oxford during the 12th to 15th centuries, none survived the Reformation. The modern Dominican permanent private hall of Blackfriars (1921) is a descendant of the original (1221), and is therefore sometimes described as heir to the oldest tradition of teaching in Oxford.
As the University took shape, friction between the hundreds of students living where and how they pleased led to a decree that all undergraduates would have to reside in approved halls. Of the hundreds of Aularian houses (from the Latin for "hall") that sprang up across the city, only St Edmund Hall (c 1225) remains. What put an end to the halls was the emergence of colleges. Often generously endowed and with permanent teaching staff, the colleges were originally the preserve of graduate students. However, once they began accepting fee-paying undergraduates in the 14th century, the halls' days were numbered.
The oldest of Oxford's colleges are University College, Balliol, and Merton, established between 1249 and 1264, although there is some dispute over the exact order and precisely when each began teaching. The fourth oldest college is Exeter, which was founded in 1314 and the fifth is Oriel, which was founded in 1326. The most recent new foundation is Kellogg College, founded in 1990, while the most recent overall is Green Templeton College, 2008 (the result of a merger of two existing colleges).
Women entered the university for the first time in 1878, becoming members of the University (and thus eligible to receive degrees) in 1920. Women's colleges before integration included Somerville College, St Anne's, St Hugh's, and Lady Margaret Hall. All colleges are now co-educational, although one of the Permanent Private Halls, St Benet's Hall, only accepts men. St Hilda's decided to accept male members at all levels from 2008. Some colleges, such as St Cross and Linacre, accept only graduate students. All Souls College accepts only Fellows. Harris Manchester College accepts only "mature students" with a minimum age of 21.

- Blackfriars Hall is operated by the English Province of the Order of Preachers, part of the Dominican Order, who also run several priories and other charitable operations. The hall does not have assets or endowments specific to it that are possible to discern from the order's accounts.
- Campion Hall is one of several institutions operated by the Society Of Jesus Trust Of 1929 For Roman Catholic Purposes. The hall does not have assets or endowments specific to it that are possible to discern from the society's accounts.
- St Benet's Hall, due to its foundation as a hall for monks from Ampleforth College, was operated directly by the St Laurence Education Trust, part of the Ampleforth Abbey Trust, until 2011. Whilst it has had its own subsidiary trust from 2012, the accounts for this have not yet been published and so it is not possible to discern the assets or endowments of the hall.
College and permanent private hall arms and colours
Each college and permanent private hall has its own arms, although in some cases these were assumed rather than granted by the College of Arms. Under King Henry VIII Oxford colleges were granted exemption from having their arms granted by the College of Arms; and some, like Lady Margaret Hall, have chosen to take advantage of this exemption, whilst others, such as Oriel, despite having used the arms for many centuries, have recently elected to have the arms granted officially. The blazons below are taken from the Oxford University Calendar unless otherwise indicated. Shields are emblazoned as commonly drawn, and notable inconsistencies between blazons and emblazons (the shields as drawn) are indicated.

- Brasenose: the blazon of the arms of the See of Lincoln given here differs from that at Lincoln College; the two forms are simply interpretations of the simpler blazon gules, two lions passant gardant or, in a chief azure Our Lady sitting with her Babe, crown and sceptre of the second.
- Lincoln: although the three stags are blazoned as trippant argent attired or they are universally drawn as statant attired or. See also note on Brasenose above.
- Nuffield: uniquely among the Oxford colleges the blazon of Nuffield recorded in the University Calendar also describes its crest.
- Queens: the depiction of the pierced mullet is quite variable; a mullet of six points is common and the piercing is sometimes indicated schematically.
- Worcester: although the six martlets are blazoned as gules (red) they are usually (but not always) drawn as sable (black).
- Blackfriars: the blazon used here is that of the Dominican Order. Blackfriars also uses their simpler shield, blazoned as sable, a pile inverted argent.
- Campion: the phrase billets of the Weld appears to be a misprint for billets of the field.
- Wycliffe: the blazon used here is simply a description of the shield as usually drawn.
Heads of Houses
The senior member of each college is an officer known generically as the Head of House. His or her specific title varies from college to college as indicated in the list below. While the Head of House will usually be an academic, it is not uncommon for a person to be appointed who has had a distinguished career outside academic circles, especially in the Civil Service.
For a list of current Heads of Houses, see Heads of Houses.
- Principal: Brasenose, Green Templeton, Harris Manchester, Hertford, Jesus, Lady Margaret Hall, Linacre, Mansfield, St Anne’s, St Edmund Hall, St Hilda’s, St Hugh’s, Somerville, Regent’s Park, St Stephen’s House, and Wycliffe Hall
- Master: Balliol, Pembroke, St Catherine’s, St Cross, St Peter’s, University College, Campion Hall, and St Benet’s Hall
- Dean: Christ Church
- Regent: Blackfriars
Until 2004, the President of Templeton was both Head of House and Chairman of the Governing Body. In 2004, the college statutes were amended so that these roles were separated. The Dean was the Head of House until 2008. When the college merged with Green, the Head of the new Green Templeton assumed the title of Principal. The Dean of Christ Church is head of both the college and the cathedral. The President of Kellogg is also Director of the Department for Continuing Education.
For some years, an unofficial ranking of undergraduate colleges by performance in Final Honour Schools examinations has been published annually, known as the Norrington Table. As the table only takes into account the examination results for the year it is published in, college rankings may fluctuate considerably.
Beginning in 2005, the University of Oxford started publishing a list of colleges classified by a "Norrington Score", effectively replicating the Norrington Table. The university claims to have published the results "in the interests of openness". Although the university says that the college listings are "not very significant", the 2005 table is the first Norrington Table with official data and also likely the first to be truly correct. Dame Fiona Caldicott, the Chairman of the Conference of Colleges, has said that in previous years some students have used the Data Protection Act 1998 to ensure their results were not published, rendering the unofficial tables inaccurate.
A tradition of the University is a friendly rivalry between colleges. Often, two neighbouring colleges will be rivals, and each college will pride itself in its athletic victories over the other one. Examples include:
- Jesus College and Exeter College
- Brasenose College and Lincoln College
- The Queen's College and St Edmund Hall
- Balliol College and Trinity College
- Christ Church and Pembroke College
- Keble College and St John's College
- University College and Merton College
- St Catherine's College and Magdalen College
- Blackfriars Hall and Campion Hall
- Corpus Christi and Merton College
- St Hugh's College and St Anne's College
As well as historic rivalries based on geographical proximity, colleges often develop foes in the sporting arena that can become full-scale rivalries, although these are usually much more short-term. A recent example of this came as a result of the 2006 rugby Cuppers final between Pembroke and St Peter's that culminated in a fight between the Pink Pembroke Panther and the St Peter's Squirrel, the respective mascots of each team.
