I agree with platypus, that nothing really can be done about it until the work load becomes too hard to handle and your child comes to the conclusion that he can perform better with them. My DS does not use any of his accommodations as well, and I leave it up to him to make the choice. At this time, his main priority is to blend in and he is doing that for a lot of reasons, but at some point, the necessity for the accommodations will overcome his needs to blend in.
