How do KCS Wimbledon and Winchester compare on GCSE / IGCSE entries at grade 9?
Comparison · GCSE / IGCSE entries at grade 9 · 2022–2023. Edition of 28 Sep 2026.
The answer · Too few shared years to call
We can compare KCS Wimbledon and Winchester on this measure in only two years: 2022 (KCS Wimbledon 73%, Winchester 58.7%) and 2023 (KCS Wimbledon 67.2%, Winchester 50.5%). 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: KCS Wimbledon (2022: 73%; 2023: 67.2%); Winchester (2022: 58.7%; 2023: 50.5%).
| Year | KCS Wimbledon (%) | Winchester (%) | Gap (points) |
|---|---|---|---|
| 2022 | 73 | 58.7 | 14.3 |
| 2023 | 67.2 | 50.5 | 16.7 |
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: 2022 and 2023. 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 2023. They can’t show 2026 results.
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.
