I think there are 3 pieces to the puzzle....home, school & peers. The school will largely determine the peers, so if responsible parents who encourage education at home pick the right school, they really have the main bases covered. Of course, you can only bring a horse to water and if the kid has no interest whatsoever in school then it won't matter a jot...but at least as a parent can say you did your bit!
I'm learning fast on the subject and I feel it is a pity this forum wasn't live when ours started school. "Three pieces to the puzzle . . . home school and peers." And I'd have some difficulty arguing the points with Firefly and I'd lose the debate handsomely. But, I'm having a Detective Colombo moment (minus the cigar and trench coat). Would I be right in saying?:- If we had (a) Good learning home environment (b) Teachers in school doing their job properly (c) All students buying into acquiring good education standards that now there would be no need for private schools, no need for grinds etc
