I've put my DCs through French school and I teach English in French schools.It is so negative, always looking for what they do wrong and can't do. When my DCs were little it used to drive me mad, my poor DC1 had a terrible report in CP (5/6 years old) he couldn't do this, he couldn't do that, it was terrible. I can remember asking his teacher, is he polite? is he calm? Does he try? The answer was yes, to all, but his report was still negative. It was the year he wa diagnosed with ASD, dyslexia and dyspraxia, but no concessions were ever made. This is my experience, however, my DCs think it's OK and don't have a problem and they have in fact both done very well. I do have conversations with my friends about if I had known would I have still brought my DCs to France? I think yes, because the positives of living here have outweighed the negatives, but I do know a few English families who have returned to the UK because of the education system and its effect on the their DCs.
As a teacher, I hear some of my colleagues screaming at the pupils which never even happened to me at at school in the UK 40 years ago, again, it bothers me more than it bothers the students.
With regard to leisure activities there are loads of associations, I live in the arse end of no-where, and my kids have had the opportunity to try archery, fencing, scouts, football, basketball, horse-riding, judo, surf and that's just the ones they've been interested in, there are loads of others (and not just for children too, plenty of associations for adults to get involved in). I think I pay 100 euros for basketball for the year, but because I'm classed as a low income family the government give me financial aid towards the activities so I think I pay about 50 euros a year out of my own pocket.
