Ofsted: Outstanding · 2022 Inspected 3 years ago Mixed Secondary Roman Catholic
9.5/10 Well above average

2nd of 20 secondary schools in Hounslow we can score. Local and same-phase on purpose: a national table mostly measures who attends.

Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds — 9.3/10 against 575 of them, against 9.5/10 nationally. So this is not simply a reflection of who attends. Both figures are results only, without the inspection grade. A lower figure here means a stronger comparison group, not a weaker school.
