Well I can comment to a degree, my son who is 6 is going to school here in the UK and in my opinion the school system here is probably worse off than in SA in some respects. Bear in mind I was my sons age almost 30 years ago so there's a big difference I'm sure, however when I was in grade 1/grade 2 I could read, I cold write (obviously not novels etc, my son, can, however if he struggles they glance over it, instead of helping) I played sport, I wrote tests (not so much in the lower years) In the UK they keep taking these tests and making them easier, and easier. Unless you have a real chronical problem you can never really fail a year in primary school. This is due to their acute fear of singling out an individual and offending etc etc.
They've taken away competitiveness, not many schools play sport against each other, there's no discipline instilled in the kids at school either, two very big contributors to the current state of affairs with the "yoof" here in the U.K.
In general I think maybe the standard of teacher is better here in the UK but, they are severely restricted as to what they can or can't do in the classroom
