Hi crisc, That is a great news! I totally understand what you've gone through emotionally. My son 8 has Asperger's and we just finished a series of evaluation for ADHD.
His school requested it because of his increasing behavioral problems at school.

I think Social skills training would be very beneficial for your son. My son's been taking those classes for years and they definitely helped improving his social awareness, peer interactions and coping skills.

Good luck on his new school!
