Re: 11 +
There are a few grammar schools about but they are highly subscribed with many students competing for each place,
So its not a question of passing the 11+ anymore they schools require lots more things in order to make a selection .
My grandson is a gifted child and my DIL wants him to go to a grammar school but in her area on average 23 children compete for each place.
A church grammar school also requires church attendance ( backed up with proof from the officiating clergy )
Children who have other talents will be given preference.
So its not easy to get into these schools and its no surprise their students do well as they are all above averagely intelligent children to start with.
But the bottom line is that students who want to do well will do well in most schools- what holds children back IMO is the disruptive nature of other children in the class which detracts from the teachers attention and teaching time.
That is why those who can afford it send their children to private schools . Classes are smaller and the schools don't hesitate to exclude disruptive influences There is then the social cache of a private school - your child wont be mixing with the rougher elements of the hoi polloi.
As most people cannot afford the exorbitant fees of a private education and cant get into a grammar most children have to take their chance with the comprehensive system and such is the competition for good ones that houses in their catchment areas cost more as parents who can afford to do so move to these areas.
