i think the approach of parents is very often really quite a simple one erm that they have a number of very well defined expectations of the school and that is as far as one individual parent is concerned, that the parents wants the child to go to the school, he wants that child properly controlled, provided that it's done in the way in which he particularly approves, and if you have fifteen hundred different parents there might be fourteen hundred and eighty five different techniques at work here, and then he wants the child simultaneously to be successful and happy.
