Results
GCSE results, summer 2025
66 pupils sat their GCSEs. Here is how they did against every state secondary in England.
The government hasn't published this school's headline results. That usually means the year group was too small to publish without identifying children.
Getting a place
Admissions policy not published.
Each council publishes its own figures on how many families applied and how far away the last child to get a place lived. We are adding councils one at a time. If you have a link to Westminster council's admissions booklet, send it to us.

The area around the school
Crime figures come from police.uk. The police record each crime at the nearest of a fixed set of map points rather than the exact spot, so “within 500 m” is only rough. House prices are from HM Land Registry sales nearby over the last two years.
