How do Latymer Upper and St Mary’s Ascot compare on A-level grades at A*?
Comparison · A-level grades at A* · 2024, 2026. Edition of 28 Sep 2026.
The answer · Too few shared years to call
We can compare Latymer Upper and St Mary’s Ascot on this measure in only two years: 2024 (Latymer Upper 41.56%, St Mary’s Ascot 41%) and 2026 (Latymer Upper 43%, St Mary’s Ascot 37%). Two years can’t show a pattern.
The figures
Not charted: fewer than 3 comparable years for any of these schools, too few to draw a line. The figures: Latymer Upper (2024: 41.56%; 2026: 43%); St Mary’s Ascot (2024: 41%; 2026: 37%).
| Year | Latymer Upper (%) | St Mary’s Ascot (%) | Gap (points) |
|---|---|---|---|
| 2024 | 41.56 | 41 | 0.56 |
| 2026 | 43 | 37 | 6 |
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
- A-level-only series. IB, Pre-U, mixed qualifications and school-defined combined definitions are excluded. CAG/TAG years 2020–21 are excluded by default; unresolved competing values are retained in the evidence record but omitted here.
- 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: 2024 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.
3 of the 4 recorded figures behind this comparison have an exact source check for that field and year; 1 is a recorded or calculated figure with its support set out in Record details. This is not a fresh check of every source.
