Has the district done a counseling evaluation on your grandson? We have a licensed counselor on site who only works with the special ed kids who have qualified for counseling services (he's not just a school counselor; he's a licensed therapist). He works with kids in the building particularly in regards to school-related issues and behaviors. They are able to go to him when they are in crisis, needing a time out from whatever is going on. He is fantastic with them and he helps students negotiate through those school-related crises that arise. That may be an option that should be looked into.
