Thanks for the thoughts. Based on your feedback we drew the IEP to to the teacher's attention and rather than responding directly (even if to say that she was referring the question elsewhere) she referred it directly to the social worker who appears to coordinate the IEP paperwork. I asked just to resolve this by phone or email, but they seem to want to have a meeting, so we have one on the calendar. The oral response idea is a good one and not just for this situation, but others where writing challenges and slow retreival speed create problems.
