My ds who has autism is in main steam school, mostly doing OK but is struggling with learning and needs extra help. He was having small group sessions to help him. But this year since September has been a nightmare with teachers off sick and leaving currently only have 50% of classes have teachers rest are all supply. So the ta who would have taken the sessions have been in other classes and has now just left! He then didn't receive any as the were focusing on year 6 Sat's. But as the school is getting extra funding for him due to sen, do I have a right to complain and find out where the extra money is being spent?
