If you happen to be near a faith school and you don't like it, apply somewhere else or move. Faith people have as much right to a school than you do.
But why should they have a greater right than others?
what happens is exactly the opposite: parents move close to best school, and move out as soon as they got 1 space secure that the other siblings are safe.
This happens only very rarely, due to the fact that moving house frequently is expensive. Admissions authorities are taking an increasingly tough line on parents who try taking short term rentals near the schools they want. It doesn't remotely compare to the hundreds of children with an unfair advantage through the availability of faith schools.
Instead of looking at faith schools you don't agree with, remove them from your list! it's not unfair that they exist and you have a choice.
Why do you keep insisting that people have a choice, thedisorganisedmum, when (a) it is obvious that the existence of faith schools means that some families have a more limited choice and (b) people have cited a number of examples here where in practice they have little or no choice because all their local schools are faith schools?
