It’s a big school and as ever there will be a range of experiences, and I’m sure some teachers make more of an effort than others.
But it’s a fact that they don’t have a “gifted and talented” policy in contrast with other schools.
And I’ve heard from a number of parents whose bright children have been let down (eg expected to stare at the walls for 20 minutes of a lesson because the child had finished all the work, and had been told they couldn’t have any additional work, and had been explicitly banned from even reading for the rest of the lesson).
Another friend has an academically average child there and she gushes about the school “It’s wonderful, they ensure all the children move forward as a group, no-one is allowed to get ahead of the others!”. Yeah, that’s not so wonderful for all kids, is it?!
It’s non-selective but so are Sandringham, STAGS and the Harpenden secondaries, all of which do better with a comparable demographic (and sibling rule, though that’s irrelevant when they’re academically non-selective in the first place surely). I’ve been comparing it only with other non-selective state schools in the area.
Yes, they do well at A level but how much of that is due to tutoring? And as you note they are selective in 6th form.
I should say I was actually really impressed when I went on an open evening at the school and I do know a lot of happy parents there, but the above put me off a lot. At one point we seriously considered moving into catchment and I’m now so glad we didn’t.
