Looks like you have a very special and bright little boy on your hands. My son is a 2E child and has dysgraphia. I would see if your school system would test him for LD. They should just based on the huge difference in scores. Writing is only going to get harder as time goes by and he will need at the very least a 504 plan in place. I am going through a bit of the same thing with my son. His problem is he compensates so well because he is so smart. They don't think he needs help. Lucky for us by the end of last year his teacher was seeing he wasn't getting any better at writing so next year we should be good to go. Keep on them and don't give up. I know it gets tiring but that is the only way to get results!
