Glad, I accept it is variations on a theme. Private education is economically selective. There is also no alternative to looking round and deciding what feels right for your child. Plus schools seem to be responding to parent demands for supurb league table places, University destinations etc, and are changing. So schools like Ibstock and Latymer Upper which a decade ago might have been seen as places where you could avoid the worst of the must get A*s in everything culture, possibly are not the same now.
It so much depends on the child. DS drifted into Westminster and gained a place at SPS. We had no idea how competitive it was, and only learned that others prepared for pre tests etc once he had a place. He was a studious child who enjoyed education, made some lovely (from diverse backgrounds) friends and though realised some of his peers were either over-anxious and pressured, or serious party goers, was not affected. I think he was very lucky to be at a school where nerdiness was normal.
DD (dyslexic) was much more insecure and was more suited to a school with a broader intake. She did a lot of EC so met children from a range of West London schools. It is clear that if parents are putting a lot of focus on their children getting into one or two brand name schools (and the amount of tutoring some got was phenominal) those children will pick up the idea that other schools are not good enough, and that the children in those schools are somehow lesser.
She says if she were in Yr 6 now she would want to apply to Kingston Grammer. Wimbledon High also has a nice mix. Yes some Wimbledon Village girls, but a catchment that spreads through Merton, New Malden etc. GDST schools have an advantage on the diversity stakes as their fees are lower. To be honest, the ex pat Chelsea crowd might sneer at schools like Emanuel, but all these schools are high in National League tables and all are more than capable of getting good students into good Universities. Its about where your child will thrive, and also (H. Holle) about what you want from a school.
