Hire an educational rights/administrative law attorney. Aside from this site, your local bar association is a good referral source.
We do not have an attorney-client relationship. I am not your lawyer. The statements I have made do not constitute legal advice. Any statements I have made are based upon the very limited facts you have presented, and under the premise that you will consult with a local attorney. This is not an attempt to solicit business. This disclaimer is in addition to any disclaimers that this website has made. I am only licensed in California.
This question was posted under discrimination, but there are not facts indicating why you believe you were discriminated against. Consult a local attorney who handles educational cases. Good luck.
