I was going to add - surely teachers are also well qualified to judge what is best for their pupils?

Presumably as FHMum says, it would mean more choice for everyone - not a situation where you are forced to send your kids to schools you are opposed to on principle.

Maybe I'm being naive, but more choice has to be better than overcrowding. I currently work in a very overcrowded educational establishment and can see first-hand how much it is struggling to provide enough literacy support for the sheer numbers of students who need our help.
