Oxford, Cambridge and RSA Examinations

Oxford, Cambridge and RSA Examinations (OCR) is an examination board which sets examinations and awards qualifications (including GCSEs and A-levels). It is one of England, Wales and Northern Ireland's five main examination boards.

OCR is based in Cambridge, with an office in Bourn, Coventry. It is part of the University of Cambridge's Cambridge Assessment which merged with Cambridge University Press in August 2021. OCR delivers GCSE and A-Level examinations in the United Kingdom whereas for other countries Cambridge Assessment operates the examination board Cambridge Assessment International Education. An important distinction between the two is that OCR qualifications must comply with UK government regulations set by Ofqual while Cambridge International Examinations international GCSEs and GCE A-Levels do not.

OCR also manages the UK's national examination centre registration numbering system on behalf of several Joint Council for Qualifications (JCQ) member bodies.
