Independent school data note
Independent schools often sit IGCSEs, which DfE performance tables don't count. Because the resulting Attainment 8 / Progress 8 / EBacc figures systematically understate actual results, they are not shown for independent schools. A-Level and destination data is unaffected and shown in the tabs above.
Latest government data shown is for the 2024/25 academic year; some figures cover earlier years.
Independent school — inspected by the ISI, not OfstedMost independent schools are inspected by the Independent Schools Inspectorate (ISI), not Ofsted, so no Ofsted rating is published here. The results and intake data above still come from the DfE.
