the school were rubbish. they wouldnt accept there was any bullying even when he got punched in the face and they didnt return my calls for 10 days.
when i finally got to see the head of year he was arrogant, aggressive and left me in tears saying that it was all down to my son and he had some sort of problem.
SNAP! I could have written that.
Definitely ask for a statutory assessment - you should apply as he's not actually attending school. Give that as one of the reasons for seeking the assessment.
He should be having some form of education while he's not able to attend school. The LA will expect school to provide him with something to do but as he's been out of school for a while the LA should be providing at least 5 hours of home tuition per week.
Try to get him signed off by the GP. Forcing him to go back to an uncaring envirnoment such as his current school will have a very bad effect on his mental health. If you don't get the GP to sign him off you run the risk of Educational welfare Officer getting involved.
I woudln't rush to get him back into any school. Look around. Speak to the SENCOs of each and ask how they would support him. If you're not happy with any of their responses then don't send him.
If the LA offer a Pupil Referral Unit - refuse. They are not places where children with long-term special needs should go. You'd just be solving the LA's problem very cheaply for them instead of holding out for the suitable placement with the right level of support in a school that will care for him.
If you don't start the process by seeking a Statement the LA will drag this out. The longer he's out of school the cheaper it is for them as they save money they would have had to spend providing the support he needs.
You really have my sympathy. Mine was forced to stop attending school at age 15 due to bullying and assualts. His mental health declined. He was referred to CAMHS and dx's with Aspergers. Only then, with the dx, was I able to obtain a suitable placement for him when he left hospital.
I woudln't want anyone to go through what he did.
Best wishes
