If you don't want to answer this question, I fully respect that. But I am wondering how is a significant fine motor delay not an academic delay? Are you referring to the academic achievement test showing no academic delay?
How is it affecting his school life? I had students with fine motor delays and we accomodated them by providing a way to type or use other technologies when their knowledge was being tested and handwriting was just a vehicle to express it. Furthermore, if they are in elementary school, this is obviously a barrier to developing writing skills.
