Read this with the answer

  • Strict 9–1 definition only. Legacy A*–G rows, transition subsets and school-published crosswalks are excluded. CAG/TAG years are excluded by default.
  • Published results describe different groups of pupils, chosen in different ways. They can’t show the effect of attending a school, or what one pupil would achieve.
  • Only the years both schools can be compared on are used: 2022, 2025 and 2026. A missing or excluded year is not a zero result.
  • Fewer than five shared years, which is too few for the period check: it needs five.
  • These figures carry the record’s existing source checks, which are kept apart from background links. This edition didn’t reopen every original publication.
  • Historical results: the latest shared year is 2026. 2026 counts only where a figure passes this measure’s usual rules.

6 of the 6 recorded figures behind this comparison have an exact source check for that field and year; 0 are recorded or calculated figures with their support set out in Record details. This is not a fresh check of every source.
