You are right. They are punishing him for something he cannot control. I would advocate for a one-on-one.Most of the people who work in the public school system don’t have experience with special needs children. They need to know that these children aren’t purposely making mistakes. They want to belong and be accepted just like everybody else. I think they need to use more positive reinforcement. My son was always in the principal’s office in kindergarten. Then we moved and now in first grade they suspended him multiple times initially. Now with a one-on-one he has not been suspended. He has also started Strattera, which seems to be helping. I didn’t want to medicate but tried every supplement and dietary restriction and he was still having such a hard time. I hope this helps.
