DC1 was at a Bromley SS grammar, DC2 at a grammar and DC3 about to start so we have had induction evenings there.
We can’t afford private. Not for one, never mind 3! Of DC1’s peers, one was intensively coached by his dad over the y5 to y6 summer holidays - no money for tutor. A large minority had parents who were EAL and struggled to converse in English. (Not a criticism, I would struggle to speak in a 2nd language too - rather to demonstrate how much harder it was for these children than some others.)Their parents worked a couple jobs each, long hours and sacrificed to get a tutor.
Obviously, there is some privilege as some families would have no spare cash at all for tuition, but in my experience, only a few parents could have afforded private and have opted for grammar.
It has been interesting being a ‘grammar’ parent. Lots of chippy comments from other parents about elitism…. But then their children applied to the Brit School at y9. Or applied for an Art scholarship at a local academy. I am not quite sure why selection on artistic, musical, dramatic talent is ok but academic ability is not.
To the OP, good luck with your choices.
