Comprehension has nothing to do with your dd's dyslexia and dysgraphia, obviously.

If the special ed teacher said that to me, I would bluntly tell her that she has a fundamental misunderstanding of the condition. I would offer to give her some reading materials on the subject, or offer to bring an expert on the disability to your next meeting so she can be better informed while writing the IEP.

I like the idea of saying "the experts say..." (I'll have to use that at our next 504 meeting!) I'm frustrated on your behalf!
