Agree with Litchick that's it's not about 'I'm alright Jack'. And that children whose parents aren't interested in their education are always going to be at a disadvantage to those whose parents are. It's about a whole attitude, work ethic, habits that are created. I just can't see that an hours tuition every week is going to make a huge change to all that. And it costs alot of money, that could be better spent elsewhere.
Nobody is saying that those children aren't worth effort, of course they are.
It's also not about having a go at 'lazy parenting' Some problems will occur anyway, and need extra support, that's a given which is why schools should be funded to deal with that anyway. Schools should not need to access extra funding because parents can't be arsed, the funds shoud already be in place. And the parenting should be in place, but if it's not, well the country can't afford to be surrogate parents. It's a nice idea, but the money isn't there.
What I've said through lots of my posts on this thread is that of course children should be supported at school, but they do need to be supported at home too. Schools should support children that are slower learners out of their budget, because every school is likely to have slower learners. That's why we have sets and TA's. The state can't sort out every single problem that is created at home.
