11th of 20 secondary schools in Hounslow we can score. Local and same-phase on purpose: a national table mostly measures who attends.
Narrow the comparison to schools whose pupils have similar backgrounds and it does better still — 8.6/10 against 815 of them, against 7.4/10 nationally. Both figures are results only, without the inspection grade. A lower figure here means a stronger comparison group, not a weaker school.
