The A Level (Advanced Level) is a subject-based qualification conferred as part of the General Certificate of Education, as well as a school leaving qualification offered by the educational bodies in the United Kingdom and the educational authorities of British Crown dependencies to students completing secondary or pre-university education. They were introduced in England and Wales in 1951 to replace the Higher School Certificate. A number of countries, including Singapore, Uganda, Kenya, Mauritius and Zimbabwe have developed qualifications with the same name as and a similar format to the British A Levels. Obtaining an A Level, or equivalent qualifications, is generally required for university entrance, with universities granting offers based on grades achieved.
