Information about school performance is published annually by The Department for Education (DfE):
School performance tables are available on the DfE website.
Schools are inspected to provide information to parents and carers, to promote improvement and to hold schools to account for the public money they receive. School inspections are required by law. They provide an independent assessment of the quality and standards of education in schools, and check whether pupils are achieving as much as they can.
You can see the inspection report for all schools on the Ofsted website.
