Either he lives in an 11+ area or not, surely? And even if he does, it's not choice, is it, it's how you do in the test.
Not really, there are grammar schools in areas that don't routinely administer the 11+. As I've already said, in our area, the 11+ is very much something you opt in to if you want to, and if not, or you don't make the grade, there is a choice of good comps or private schools.
I am saying it's a weak argument to say that you support a system because the results for a minority are perceived to be better, and the rest must just have unsupportive parents and therefore need to be left to one side.
I didn't say the results for a minority are perceived to be better. I'm saying that children at grammar schools generally do well. Better doesn't come into it, because I don't see it as a competition. As long as my dc are doing well in relation to their own ability, I don't care how they are doing in comparison to others, it's irrelevant.
I'm also not saying that those that don't go to grammars have unsupportive parents, or that if they do, they should be left to one side. I'm saying that if all parents were supportive then it's likely that all schools would be good, and the alternatives to grammar schools wouldn't be seen as something undesirable.
