Eton minus Westminster
Eton and Westminster
Westminster higher (8.7 pp); 6 of 6 tested periods point the same way.
Eton’s recorded result was typically 8.7 percentage points lower than Westminster’s across 5 shared years (2015, 2016, 2017, 2018, 2019). “Typically” means the median of the annual differences.
Quick period check: Stable across tested windows (Windows tested: all matched years, the latest three and the latest five matched years, and each matched year left out in turn. Not every eligible window is tested here; the claim checker does that.)
Exact gaps and calculation details
- Latest shared year · 2019
- −8.7 pp
- Typical annual gap
- −8.7 pp
Positive gaps put the first school higher; negative gaps put the second school higher. Each shared year counts equally in the median.
How verdicts are graded: a verdict needs at least 3 matched years, and with fewer only the values are shown. A typical gap under 1 percentage point, or a direction shared by fewer than 60% of the tested periods, is reported as marginal. Periods are tested as on the claim checker, with at least 3 matched years each.

Does choosing different years change the picture?
We compare the full period, the latest three and five available years, and the result when each year is left out in turn. This checks whether the direction depends on a particular year. Shared years need not be consecutive. Each figure is the median of the annual gaps, calculated before rounding and displayed to one decimal place. These are the only windows tested on this page; the claim checker tests every eligible window with at least three or five matched years.

Missing years and figures we cannot compare
0 entries explain gaps or figures left out of this comparison. Some figures exist but count different things or have unresolved source differences.
No observations were excluded for this definition and period.
What can you conclude?
This comparison shows whether a gap persists across the recorded years. It does not tell you which school would be better for a particular child, how much teaching contributed, or the chance of admission. The period check is not a test of statistical significance.
Prior attainment, admissions selectivity, subject choices, cohort composition and publication coverage are not controlled. Source precision varies; extra calculation digits do not create extra source accuracy. Missing numerical denominators remain unknown.
