England (544 schools): Comprehensive. Schools identified from DfE A-level and AS-level results 2024/25 — every school that entered candidates for Latin, Ancient Greek or Classical Civilisation. School type and coordinates from the GIAS register. GCSE provision is inferred (if a school offers A-level, it almost certainly offers GCSE), except sixth form colleges which show A-level only.

Scotland (22 schools): Partial. Curated from school websites and published sources. Scottish qualifications (National 5, Higher, Advanced Higher) are mapped to GCSE/A-level for filtering.

Northern Ireland (7 schools): Partial. Curated from school websites and the Classical Association.

Universities (478 across 59 countries): Universities offering undergraduate and/or postgraduate programmes in Classics, Classical Civilisation, Ancient History, Latin or Ancient Greek.

MA includes taught masters (MSt, MPhil, MLitt, MSc where used as the taught postgraduate degree). PhD includes DPhil (Oxford). Coverage spans six continents: comprehensive for the UK, Ireland, Western Europe, and North America; strong for Eastern Europe, Russia, Australasia, South Africa, and Latin America; selective for Asia, the Middle East, and sub-Saharan Africa.
