It can sometimes help when the child at least attempts to self-advocate. I know my son loudly announced to his kinder teacher that he could ALREADY READ BOOKS, THANKYOUVERYMUCH. There wasn't a lot of differentiation, and we still had issues, but she did at least give him 1st grade worksheets, and let him read chapter books to the other kids.

Maybe your daughter could write her teacher a little note (about anything, honestly!) to show the teacher she can do it?
