If the government want to see exactly what is wrong with the grammar school system they need to do no more than read this thread!
The 'haves' get the best of education for their children.
The 'have nots' get the worst.
Unsurprisingly some of the 'haves' not only want to keep it that way they want to ensure it (except for a deserving, miniscule, percentage)
Apparently 10 yrs is ample time (almost their entire lives!) to select children- regardless of the fact that the gap is as much as 19mths in attainment between the 'haves' and 'have nots' . I can't be bothered to look back to see who said swapping at birth made no difference because 'nature would out' ( I wonder if adoptive parents would be happy with this?)
While I can see that children need to be set for academic subjects I can't see why they need separate hockey lessons, school choirs, orchestras, drama groups etc etc
( The only 2 adults that I know who have made music a career - flute and violin- both failed 11+)
I would feel that Bertrand's selection by 5 yrs according to Boden is pretty accurate. I could do a pretty accurate one with 2 yr olds! But that is where I would spend the money - on the 2 yr olds that desperately need it.
I know a 3 yr old now - as bright as a button! However I don't see her doing too well because her parents don't play the system and don't even realise they need to play the system!
