Your views are always very balanced CM.
I posted this topic because I've heard people comment before that they wouldn't send DC to and independent but rather a GS because at GS your child is living in the "real world". Clearly NOT! !
I suppose that is why I drew a distinction between the different kinds of grammars.The ones that give priority to local children or siblings do
have a much wider social mix.
In Essex, KEGS, CCHS, CRGS and Colchester girls just take the top scorers.The Southend schools have a catchment pass mark.This makes for a more varied social mix and would be more the "real world".I suspect this is true in Bucks and was true of some of the grammar schools in the L.Bs of Sutton &Kingston depending on admissions policy.
So I agree that the top performing grammars have far less of that " real world " social mix and, for me, that is a negative.
Small numbers of disadvantaged children at indep schools is better than none at all.
I do wonder how they fare there though but that's probably a whole other thread....
