One of the student's on my caseload has DCD Severe to Profound and he is nonverbal. Recently, he has been screaming more and more and scratching those people who work with him. There was one day when he screamed over 100 times in a fifteen minute period. He seems to scream when he is excited and mad. Very defiant and throwing objects too. We have tried visuals and a keeping hands to self social story. He will not keep his hands to himself in the hallways and will scratch, hit, and pull students' hair.

Any suggestions?
