FERPA stands for the Family Educational Rights and Privacy Act. It gives parents the right to inspect, review, and receive a copy of their child's educational records. Under the law, parents may request that school officials explain the contents of the record, and if the parents disagree with its contents, they may ask the school to amend inaccurate information. FERPA also forbids the disclosure of any "personally identifiable information" about the child without parental consent.
I would recommend hiring a lawyer if you are having difficulty accessing or amending your child's file or if you feel confidential information about your child has been compromised.
