Hi
Welcome. I do not know anything about this either but I would suggest you try to get more information from your son's school. If they're not helping, just keep pushing.
I was a registrar at a high school for many years and I do know that when parents really push, they do get answers and help.
Good luck. I know this has to be tough. I never had behavioral problems with any of our kids. Just addiction with my youngest which ain't no picnic!
