Consult an educational rights attorney, and also complain to the school.
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 is confidential information which never should have been disclosed. Options include filing a complaint with the Family Policy Compliance Office (U. S. Department of Education- link below), filing internally with the District or filing with your local grand jury. There may be other options as well.
The school should be confronted on the matter and take corrective actions. Your daughter may request counseling, etc. to assist her in recovering from the situation. If you involve an attorney, it can facilitate this not happening again and the District would know you are serious. Or, you can approach them on your own.
Best of luck,
Law Office of Michelle Ball
California Education Attorney advocating for the rights of parents and students since 1995.
