Getting a place
Admissions policy not published. As a Roman Catholic school it may put families of that faith first. Check the school's own admissions rules.
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 Windsor and Maidenhead 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.
