Jeni,
I agree with other posters you must continue to advocate for your child. I might try reaching out to the principal one more time. Try arranging a one on one meeting. That way the principal does not have to impress any underlings during the meeting. Come armed with research and let her know firmly but in a kind way that if she cannot come up with a plan to accomodate your child that you will need to look to others within the district for help with a plan. My experience has been that most schools desparately fear losing their brightest students and if she finds that her strong arm approach to you isn't working she may relent a bit. Give her the opportunity to relent without losing face.
