My DS is going into year 11 having repeated year 10 because of school avoidance (mental health breakdown- ASD high functioning). He is doing his studies online. He is interested in rejoining a school or college for A levels now that he is in a better place so he can make friends, but will be a year older than he should be. He can roll on to do A levels with his online school but before we started looking I don’t know how this is viewed? He would be 17 starting and age 19 finishing. Would any sixth forms attached to a school take him or is he too old for a school environment?
