(1) When you think of English universities, Oxford is likely one of the first ones to come to your mind. The University of Oxford is a research university located in Oxford in England. The university is the oldest higher school in the English speaking world. The evidence of instruction dates as far back as 1096
(2) Like many of the older English universities there is not one "campus" per se but rather colleges, departments, living accommodations, academic buildings, and other important buildings which are located throughout the city of Oxford. There are over 22,000 students at Oxford, including over 11 housand undergraduates and 9,857 postgraduates. Nearly all Oxford students are employed or go on to graduate studies after they leave Oxford. Over 80 Nobel Prize recipients have been associated with Oxford.
(3) Oxford is a collegiate university consisting of the central University and colleges. The central University is composed of academic departments and research centres, administrative departments, libraries and museums. The 38 colleges are self-governing and financially independent institutions which are related to the central University in a federal system. There are also six permanent private halls, which were founded by different Christian denominations and which still retain their Christian character. Every student at Oxford is a member of a college. The college provides accommodation, meals, a library and IT support.
(4) The collegiate system is at the heart of the University's success, giving students and academics the benefits of belonging both to a large, internationally renowned institution and to a small, interdisciplinary academic community. It brings together leading academics and students across subjects and year groups and from different cultures and countries. Its intense interdisciplinary approach inspires much of the outstanding research achievement of the University and makes Oxford leader in so many fields.
