Just wondering what schools around Scotland do regarding expulsion / exclusion.
DD is in S3 and has just had a new boy join her class from another secondary nearby. In the few weeks since this child joined the school he's been sent out of class every day, got into numerous fights and last week (according to DD) the police were called after he pulled out a knife and threatened someone with it. 
In my day - and I'm aware that makes me sound ancient - that child would have been expelled. He would have been in the local List D "naughty boys" school but those don't seem to exist any more.
Interestingly, DD reports that the other "naughty boy" in her year left at the same time as this new one arrived and went to a third school. It seems to an observer that the local schools are passing the problem pupils around between themselves on a "we'll take Bob if you have Adam" and so on.
So far the naughty boy hasn't as much as looked in DD's direction - he's more interested in dominating the boys. But if I were the parent of a boy he was wanting to fight with or pulling knives on I'm not sure how I'd feel about him remaining in school.
