The figures
- Winchester
- Latymer Upper
Each school against the same scale and years.
Exam eras: 2019; 2020–21 (grades set by schools); 2022 (return to exams); 2023–25; 2026. The rule beneath the axis marks exam conditions, not schools.
A break in a line means a year has no comparable figure; nothing is estimated. The figures behind the chart are listed below.
| Year | Winchester (%) | Latymer Upper (%) | Gap (points) |
|---|---|---|---|
| 2019 | 44.4 | 47 | −2.6 |
| 2025 | 50 | 62 | −12 |
| 2026 | 61 | 64 | −3 |
Figures to two decimal places at most. A figure known only within the school’s rounding is shown as a range, never as its lower end.
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: 2019, 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.
2 of the 6 recorded figures behind this comparison have an exact source check for that field and year; 4 are recorded or calculated figures with their support set out in Record details. This is not a fresh check of every source.
