My son is 5 years old and in reception, he has autism and sensory processing difficulties, he is mostly non verbal. He has been excluded from school as he bit an adult, we have had issues with him being physical at school towards the adults mainly due to their lack of understanding and failure to properly implement sensory breaks as stated in ehcp (though they say they are doing this it is obvious they are not). He has very little speech and is physical no where else than school as they are not managing his sensory needs and he feels overwhelmed, they are also not picking up cues of when he is stressed. We are working towards a special needs school but obviously takes time. Is it legal for the school to have excluded him when he does not understand what he did wrong and that it is related to his asd?
