Help and Support

Hi I am new to the group  need some help and advise. My son has Autism and ADHD his in Year 9 now. His been having a bit of difficult year at school. Some students in his class call him names and are nasty to him. My son has been getting very angry in school and his behaviour the school says is out of proportion as a result of this they decided to keep him in isolation all day. Isolation don't work for him it just made him explode at home after school. This is been ongoing for 3 months am not sure what I can do. Any help will be appreciated
