some schools have more than their fair share of erm.. Challenging children. Middle class parents can get their children a better peer group by buying an expensive house, praying or going private. Children from low income families are trapped in poor schools as their parents cannot move as easily.
I think that all state schools should prioritise 15% of places for fsm children so that poor children can have a chance of going to the best comprensive. Before I get jumped on most fsm children are NOT problem children. However they are more likely to educated at poor quality school. Children who get excluded should be given a place at the best school possible even if that means going over 30 in the class.
Children from wealthy families suffer less from attending a weak school. Middle class children can help to raise the aspirations of their classmates.
Perhaps private schools should take a few difficult children as a condition of their charitable status.
