Results
The government does not publish comparable results for most independent schools (IGCSEs are left out of its measures), so none are shown here.
Getting a place
Open to all. There is no entrance test.
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 Hounslow 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.
