My son has an EHCP as he is high functioning autistic, in the plan it says that he should be monitored at breaks as he cant cope with these unstructured times. He is usually just boistrous / rough play even though he is 11 and all his peers have moved on from playing . On Friday he was being wound up by other kids as they know he has a low flash point. One child actually dared the retard to hit him, unfortuntely he got him in a choke hold and it took two adults to get him off. His usual supervisor was on training course and no other provision was put in place. I am clearly very upset by this and understand that my son should not have behaved like this under any circumstances. The other child's parent wants him excluded for the rest of the term (a week), he is in Y6 and it is his last week and clearly something went very wrong. He has never done anything this extreme before. HT said she wont exclude due to his SEN. How can I avoid this happening again at his new school, he can be triggered really easily and I don't know what I can do to help.any advice appreciated.
