I think the main difference between private and public schools (in Denmark) is that private schools can expel kids who sabotage the lessons. Public schools cannot expel kids. They can't even make a kid move to another school. Denmark has also closed "special classes" for disruptive kids and classes for autistic kids and put the in the normal classes. So now you have the autistic kid who can't handle noise in the same class as pupils who like to make noise. In addition to this, the problem kids are often made into the victims. So you are not allowed to blame them or tell the parents they need to parent their kid. So we also have an exodus of teachers. I cannot see how you can survive as a teacher in such a situation.
