I stand by the fact that Scotland education is poor, private schools are one to two whole years ahead.
I have just had both my DC go through a mediocre state school and on to good Uni courses (Edin and Dundee) and I work in a similar state school as a support assistant.
I don't agree that Scottish education is poor, or at least that it's much different that it's ever been. The struggle to adequately educate some pupils starts from before they have even started school as they come from homes who don't value education.
There's a particularly massive struggle to educate many boys who won't, and have never, read a book because they spend all their spare time in front of screens. According to a recent piece of research, in general boys don't improve upon their reading skills from when they leave primary schooling, and many boys arrive with a reading age of 8-10.
Schools offer the content and are ambitious for the pupils, but unfortunately they can lead the horses to water but they can't make them drink.
Something else went wrong in Scottish society long before the current school issues, something which affected the ambitions of their parents.
