Eton v Westminster
Westminster comes out higher
Westminster comes out higher than Eton on the share of A-level entries awarded A* when the available years are compared. The same school comes out higher in every period we checked.
Based on 5 years with comparable figures (2015–2019).
How we worked this out
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.
We checked 6 periods, each with a start year, an end year and at least 3 years with comparable figures. Eton came out higher in 0, Westminster in 6. These periods overlap, so the counts are not probabilities.

- −8.7 pp
A positive gap puts Eton higher. Each shared year counts once in the median.
How we reach the conclusion
With fewer than 3 shared years we give the figures and no verdict. If at least 25% of the year ranges we test point the other way, it depends on the years. A typical gap under 1 point is too close to call. A gap of 1 to 3 points that at least 75% of ranges agree on holds up, narrowly; 3 points or more with at least 90% agreeing holds up, and with 75% to 90% agreeing it holds up, mostly. Anything else is mixed. On Test a claim, a typical gap that favours the other school points the other way. Where comparable figures are known only as a range and the verdict differs between the two ends, it depends on the schools’ rounding. Every year range is tested, as on Test a claim. The comparison rules in full.
Share of published A-level entries awarded A* in the named examination year.
What this result does and does not cover
These figures cover A levels alone. IB, Pre-U and combined-qualification results are kept separately. Teacher-assessed results from 2020–21 are left out unless you choose to include them. Where publications disagree and the difference remains unresolved, both figures stay in the source record and neither enters this comparison.

Does choosing different years change the picture?
We re-run the comparison on the last 3 and 5 years, and with each year left out, to see whether one year drives the result (at least five shared years are needed). The verdict above already tests every year range; Test a claim shows them all.
Eton minus Westminster
The same school is ahead in every one of these choices of years.
Years left out, and why
0 years or figures are left out: missing, measured differently, or publications disagree. A missing year counts for neither school.
Nothing is left out for this measure and period.
What these figures can’t tell you
The results can show whether a lead persists through the available years. Explaining it takes more: who the school admitted, which subjects pupils chose and how they were taught. Ask about those things before drawing a conclusion about your child. This comparison cannot predict their grades or admission, and it does not test statistical significance.
