northernlass1, no I haven't yet found any answers to the 11+ question. I haven't yet phoned the grammar schools, to ask about the percentage of intake from private schools, if that's what you mean.
I have heard so much conflicting advice about the 11+ that I don't know who to believe. We live on the edge of our borough. There are no grammar schools here, so no 11+. Our local non selective secondary schools are all rated below average, but I haven't visited them so can't comment from first hand knowledge. Chances are my son will go to one.
However, the neighbouring borough has grammar schools, so children in our area can sit that
borough's 11+.
My son's school offers little help to 11+ entrants, though I believe they sit a few test papers the week before. Also, the teachers officially do not adivise parents, since the borough frowns on 11+ selection. They don't tell cetain parents to put their child in for the 11+. They will not recommend a particular tutor or do any specific 11+ ability assessment at school.
Unofficially the teachers will give a little more help - advising on what test papers to buy, that sort of thing. Children at my son's school do enter the 11+ and pass, but they do this outside the system. IME parents advise and support each other, but most of us are in the dark, too. I have no idea, for instance, if my son's weekly 1 hour 11+ coaching is doing any good. It might be going over ground covered at school. The tutor could be rubbish for all I know.
When I contrast this with the a statement made earlier on this thread about a private school getting nearly 100% of its children into the grammars, it makes me worried. Yes, I know that passing the test calls for natural ability and no amount of teaching can make a child pass, but what about all the inbetween children who might pass, given some support - and might pass well and opposed to just scraping through if they have some good pre test support? The situation is not so black and white then.
Selection to grammar schools in my area is not just about passing the 11+. That is just the first hurdle. About 2,500 children pass the 11+ but there are only 900 grammar school places. They go to the children with the highest marks. I might be paranoid here, but I wonder how many state school pupils pass the 11+ but don't get quite high enough marks to get to the grammars? how does this compare with pupils who have been extensivley coached at school? So yes, you can have statistics showing that many state school pupils 'pass the 11+' but when you look at those who actually get offered grammar places, the percentage drops off. I might be way off here - this is just me rambling.
I cannot see why the 11+ covers areas not taught to children who do the national curriculum. Why is this? My son will be tested on long division in this October's 11+. He will get taught this in year 6 but not in time for the test. What would happen if we didn't send him for coaching or couldn't teach him this ourselves? he would not be able to answer the questions, hence he would lose marks. And with the competition for entry to grammar schools here, marks count.
I know that much of the 11+ tests ability, but not all of it. And, having looked at the test papers, IMO they would be very daunting to children who were not familiar with the test process. So some coaching is needed. The sixty million dollar question is how much? If I believe the advice from 11+ borough's education department, all I need to do is go through a few test papers with my son. If I believe other parents he needs months of extra tuition and homework. If I beleive the school, I can do it all myself with him at home. If I believe the tutor centre, their many years' background knowledge of the tests will give my son the edge.
I am not saying that I believe all private primaries hothouse their children - I am absolutely sure they don't. I am not saying that it is wrong to send a child to a private primary - each to their own. I am just higlighting the differences as I see them in my area.
