I agree Retro.
There is some sort of weird opinion on MN that the middle classes are somehow doing something harmful by doing the best they can for their children's education.
I don't get it at all. Surely it's a good thing when parents support their children's education.
If criticism is deserved anywhere (which I don't think it is) then surely it's the parents that don't bother to support education that should be told they should do things differently?
Trying, I admire your POV, but I think you need to be careful not to assume that home tutoring is something that all parents are capable of. Like you, I believe the vast majority can have a good go at it, but it is very difficult for many people.
Speaking from personal experience, and bearing in mind that I did home tutor, I could not have tutored my child in maths. My maths ability is just not good enough, and my child's maths ability was greater than mine when he was in year three. Honestly.
If he had needed my help with maths to cover things that he hadn't been taught at school yet, I would have seriously struggled. I could have spent hours learning the subject matter myself in order to teach it to him, but it would have been bloody hard! I would have worried the whole time that I was doing it wrong. That would have been enough to put me off doing it, but then if my child's maths ability hadn't been high then we wouldn't have gone for the 11+ in the first place.
Home tutoring did get my child a super selective grammar school place, but only on the waiting list. It wasn't good enough to guarantee him a place at the school, because quite simply, there is no way in this world that me and our unsupportive state school could have given him preparation equal to that of a private school with additional tutoring.
It's pointless to pretend all parents can provide good enough support to give their children a decent chance at a highly competitive exam, especially when they not only need to give enough support that their child gets the pass mark, but they also need to ensure they get a high enough mark that they are in the top 100 out of the 600 that apply.
You have to remember that many children don't get places at grammar schools even when they have passed the exam.
