I would ask the school their thoughts on this. They may want to sit down together, or may warn against it. Since they know the other student and maybe the parent, they would have the most constructive answer.
I hope the teachers are working on determining the triggers and addressing them. That’s the only way to truly impact behavior. If they haven’t yet, I’d request that they do an FBA and formulate a BIP.
