I rang a school last Tuesday in response to a job advert. They said they would post me the information.
On Saturday I got a card from the post office to say they had some post for me which had a fee owing on it. I could only get there on Monday evening, the letter was from the school who had not put enough stamps on!
The deadline was Tuesday, so it's a good thing I didn't want to apply. The school also didn't specify the age group.
