The other thing you can do is get a special ed plan in place for your dd if she has an ADD diagnosis and gifted IQ scores. Perhaps she can be excused from certain busy work or allowed to work in her own way. Unfortunately, however, to some extent she will have to learn to work within the system both for school and eventually for most kinds of work.
504 plans are what they do for 2e kids here. Dd has 99.9th percentile IQ scores and an ADD and anxiety disorder dx from a psych. At this point, her school seems unwilling to do a 504, though, b/c they feel that the things the psych suggested, such as oral testing, would be something all students would benefit from and it would be unfair to give them just to her.
If I were sure that there were a specific accommodation that were likely to help her, I'd push for it anyway, but I honestly don't know what is likely to help. She did have an A- in the GT reading class on her report card and did well on a recent math mid-term (A- with the few extra points the teacher will give them for making test corrections). She isn't doing poorly, per se, in these GT/subject accelerated classes overall. She's just erratic and doesn't feel successful. The GT teacher is willing to try letting her test in a separate room to minimize distractions and so she doesn't focus so much on when everyone else is finishing and turn in her paper at that point whether she's done or not.
I did set up a shadow day next week for her at school A as well.
