Disruptive behaviour is just the results, the cause might be exhaustion due to the classroom being to much for the nervous system. Over-sensitive hearing is one common symptom and for me it's hard to imagine how normal people manage to have a conversation in a room with more people having other conversations. Too many kids around, that's too many social interactions that are preferably avoiding. Allowing an autistic kid to stay back in the classroom and not being force to go out to play in the breaks is one solution I've read in a book. Shorter hours, less or no homework, less or no expectations in their learning progress can help. Remember: Autists have to learn and cope with this new social situation first before they have the strength to progress intellectually. But even when the kid is normalizing, careful not to overwhelm them again, because they might use up all their energy for the school day and just break down at home. School is a horrible place if there's the same treatment and the same expectations on every kid.
