My son's school doesn't allow parents past the school gate in the morning. There are big high fences up around the whole school and teachers stand at the gates preventing entry to anyone apart from children. If you need to go to the office for any reason, you have to ask the teacher at the gate.
The main concern I have though is that I have a total lack of contact with my 6 year old son's teacher. For instance if he is feeling a little under the weather in the morning I am unable to let his teacher know. I haven't seen his classroom yet this year and we only figured out a week ago what the procedure is for handing in homework (after three missed deadlines).
You can talk to the teacher at the end of the day, but when there are thirty parents all wanting to do the same thing with the same teacher, it's not easy!
Is this normal? I don't remember it being anything like that when I was a child.
