I am an ex-school governor,believer in genuine community cohesion, parent, secularist and humanist celebrant. I believe that genuine education would be inclusive of all, without segregation based on wealth, class, academic ability etc but especially not divided along the supernatural beliefs of parents!
The middle classes will always try to reproduce grammar schools/ two tiered schools based on academic exam results as part of the weeding process for University entry. That is NOT the way to organise education for all.
New Labour paved the way with their "academies" ensuring that some schools would always be "better" than their neighbouring schools. It's nasty and invidious.
