Mo, what information and resources do you have already? Have you had a neuropsych eval that documents strengths and weaknesses?
This sounds to me like the school is not putting adequate resources into the situation. If you had an IEP instead of a 504 you could get OT for the writing and/or pushed-in or pullout special ed support for written expression, both of which seem highly relevant.
What I know about disorders of written expression makes me think, "of COURSE he's not working efficiently; he's working against the disability" but it may be hard for the teacher to see that unless she is shown how to see that and work with it.
