My DD went there and she liked it, but:
Many of the teachers seemed really cynical and fed-up and I think the girls picked up on that. There was a high turnover of teachers during DD's time there and morale was clearly low.
There were far fewer opportunities for sport, music, trips etc than local state schools - it's very small and the site is cramped, with woeful sports facilities.
There was unfortunately some bitchiness amongst the girls, though I think her year group was particularly bad for that.
DD was underperforming for ages and being very lazy, and school never mentioned it at parents' evenings etc, so I thought all was well until she got a clutch of D grades in mock GCSEs. I sent her to maths tutors etc for the last few months and she easily got 10 A* in the real thing, but this wouldn't have happened if left in the hands of the school.
A couple of truly awful things happened, eg DD and couple of friends got involved with a paedophile teacher (later convicted), and the only support we had about it was from police, not a single word from the school throughout. Also, she had an accident in PE and broke some ribs, and the school didn't even bother to contact me. I'd say their communication was dire!
DD left a couple of years ago, and there's a new Head now, so things might be different. She did make lovely friends, that's about all that was good about it.
Have probably outed myself here but oh well! Am off to NC..........
