I've been into lots of primary schools (as a teacher) and apart from the odd few, I'd be quite happy sending my child to a state school.
I think when it comes to secondary schools I'd be happy enough to send my child to one of the local grammar schools (there are 3 around here!) and although I wouldn't have any doubt that the quality of teaching would be poor in one of the local comprehensive or community college, the calibre of child that yours is mixing with might be dubious (in some cases!).
However if we're talking about doing well in school, if you have a child who is hardworking they will do well wherever they are and if you have one who isn't prepared to put in the work, they wont whether they're in private or state.
