Catherine Jenkinson-Dix, Head of Ely Community College decided to introduce a zero tolerance policy on behaviour. Nothing unusual about that, my own school had one. (For almost an hour and a half)
What is incredible is that she actually went through with it, sending naughty kids to work in the school hall and generally inconveniencing them. It's an effective idea which won't take long to work. She might make the headlines, having to send hundreds out for minor misdemeanours, but kids aren't daft- once they realise you are serious they will start to behave. The scuzzy parents will moan a bit and make up daft stories, but if she persists then in just a couple of weeks she will have a school to be proud of.
So why don't more heads do this?
Because it takes courage.
