King’s College School, Wimbledon, IB Diploma 2025: All subjects · published qualification aggregate

Checked against the original: 3 figures.

What it counts

Source: Department for Education performance tables (subject-level data). Qualification, as the DfE names it: International Baccalaureate. Published group: ASIZE=5; GSIZE=20; Grade structure=45,44,43,42,41,40,39,38,37,36,35,34,33,32,31,30,29,28,27,26,25,24. 2025 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. “No result” covers ungraded, absent, disqualified, incomplete and similar entries; it doesn’t necessarily mean a fail. 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.

What it counts: Original government underlying subject-results workbook. Source qualification: International Baccalaureate. Published group: ASIZE=5; GSIZE=20; Grade structure=45,44,43,42,41,40,39,38,37,36,35,34,33,32,31,30,29,28,27,26,25,24. 2025 means the year students completed advanced study, not necessarily the year of each examination. The original population includes up to three years of 16–18 study. Earlier AS awards remain included even if pupils later took A2; this is not the current Year12 AS cohort. Entry counts are qualification/subject results, not a school-wide pupil denominator. School headlines and these government cohorts can differ. No cross-source total, percentage or annual grade trend has been calculated. No result includes ungraded, absent, disqualified, incomplete and other no-result cases in the original metadata; it is not necessarily a failure. Published exam cohort: Other academic. This is a published qualification aggregate, separate from subject results and entry tables. It is never added to those rows.
