I am in too minds about tutoring. I know someone who is the head of a state primary school in an economically deprived area, who volunteers their time to tutor academic and non academic children.
The tutoring styles varies across the children's interests and needs, it's also free.
On one opinion, if a child is showing academic abilities beyond the curriculum taught at state school, then extra support for the child should be found. Just the same we have Sen for children who need extra support.
For example my DS4, can barely write his own name, but can tell you all the planets in the solar system, the effect of gravity, tell you all about the dinosaurs, each species, how they became extinct, oh and then tell you all about volcanos too. Thats just a snap shot. But I bet the first thing his reception teacher come September will say is, he can't write his name. Because she can't tick that box.
I can afford to expand my child's interests, take him to London to see the science museums, as one example and will probably consider tutoring if he is still "bright" by senior school, where he will need to pass the 11 plus for the private grammar school. Even if he doesn't need it.
So on the second opinion on tutoring is that, it's not free mostly, and therefore only children who have "available" parents or parents who can afford to outsource the tutoring benefit.
Formal tutoring of 5 year olds, is too much.
Trying to change the ability of a child through tutoring, definitely too much.
Parents paying for extra support to boost their child's academic interests or seeking grants, free options. I agree with.
