This report looks at the provision of A level subjects in England in 2021. Provision in a subject is defined as the number or percentage of schools with at least one student taking the subject. This report was produced using publicly available data from the Department for Education's (DfE) "Find and compare schools in England" service and the dataset consisted of Key Stage 5 (KS5) entry numbers for all subjects provided in each school and college in England. Provision of other qualifications (e.g., Pre-U, International Baccalaureate, Cambridge Technicals, BTECs, etc.) was not investigated. The level of provision is presented by the following school classifications: school type, school attainment, school deprivation level, school sex composition, and school size.
