The Department for Education's GCSE measures do not count IGCSEs, which many independent schools take instead of GCSEs, so the Attainment 8 and English and maths figures it publishes for St John's Preparatory and Senior School can understate its results. We do not rank or compare them; ask the school for its own GCSE and IGCSE results.
