Thank you for all your replies. I spoke with an attorney with an interest in education, and she advised that if I bring an attorney that the school will want to postpone the meeting and have their attorney present too.
I'd like to "soften" the approach by bringing an advocate. I have approached a couple of local "special education" groups but have not received any replies in the past week. I'd like support from the Davidson Young Scholars Program but have not applied yet (no official test scores yet).
Any ideas on advocacy groups? We are in Wake county, North Carolina.
