What it counts

Source: Department for Education performance tables (subject-level data). Qualification, as the DfE names it: Pre-U Principal Subject. 2023 is the year pupils finished the course; exams in it may not all have been sat that year. The DfE counts results from up to three years of 16–18 (sixth-form) study, so this isn’t one summer’s exams. Includes AS grades from earlier years, even where the pupil went on to the full A level, so this isn’t just this year’s Year 12. Counts are subject results, not pupils. The DfE counts a different group, so its figures may not match the school’s own headline. We don’t combine DfE figures with other sources, or calculate percentages or yearly trends from them. Original qualification group metadata: Level=3, ASIZE=1, GSIZE=4, Grade structure=D1,D2,D3,M1,M2,M3,P1,P2,P3. Distinct source size/grade groups are retained separately. Exam group, as published: Other academic. This is a published qualification aggregate, separate from subject results and entry tables. It is never added to those rows.
