I can see where you are coming from Bath, the way I see it there are certain rules put in place at school so that everyone is on an equal footing, I would expect my childs teacher to present herself/himself in a professional manner to be an example to the children. I would judge them on their appearance, it is a fact that you are judged on your first appearance even though people may change their mind as they get to know you. It is the same with kids they are judged at school on their appearances and not everyone will take the time to get to know them. It could lead to people forming opinions that could last a life time. This is probably more of a problem for people who live in towns rather then in cities. JMO
