Being selective means they can kick out pretty much any kid for any reason. The state schools then have to deal with them.But does being selective on religious grounds guarantee good kids?
As I've said it's not the religious angle, it's having any type of layer of 'them and us' criteria. I thought all areas of life was correctly squeezing this type of thinking out.
They're a state school funded by all of us, the school can have their preference and by all means promote themselves as a CofE leaning school and be a greater attraction to students whom think likewise BUT I can't see how they can force that on the education authority during the selection process.
So by getting rid of those who behave poorly, they can spend more time educating and get better results.
Many of them receive sizeable donations and can run smaller classes too.
