What a Parent Can — and Cannot — See Once a Student Turns 18
The starting rule is the Family Educational Rights and Privacy Act, known as FERPA. Under 20 U.S.C. § 1232g(a)(1)(A), a school that receives federal funds may not deny parents the right to inspect and review their children's education records, and must grant a parent's request within a reasonable time, and in no case more than 45 days after the request. Subsection (d) then moves that right: whenever a student has turned 18, or is attending an institution of postsecondary education, the permission or consent required of and the rights given to the parents belong only to the student.
The U.S. Department of Education calls that student an eligible student: one who has reached 18, or who attends a postsecondary institution at any age. Its page Who is an eligible student? states that once a student becomes an eligible student, the rights afforded his or her parents under FERPA transfer to that student. Its page What is FERPA? describes those rights as access to education records, the right to seek amendment, and some control over disclosure. In plain terms, a 17-year-old freshman's records are already the student's to control. That is why a dean may decline to discuss a conduct file with a parent, and why the student's willingness to sign a written consent often becomes the first practical question.
The first exception concerns dependents. Under 34 C.F.R. § 99.31(a)(8), a school may disclose information from education records without the student's consent to parents of a dependent student, as section 152 of the Internal Revenue Code defines one, and 34 C.F.R. § 99.5(a)(2) confirms that the transfer of rights does not prevent such disclosures. The word is "may": the school is permitted, not required. For a family that claims the student as a dependent, this can be a second route to records, though how far it goes depends on the school's own practice.
The second exception is narrow. Under 20 U.S.C. § 1232g(i), federal law does not prohibit a college from telling a parent or legal guardian about a student's violation of a law or school rule on alcohol or controlled substances, whether or not the information sits in education records, if the student is under 21 and the college determines the student committed a disciplinary violation. This rule does not override a state law that prohibits such disclosure. In practice, a college may share an alcohol-related finding but has no obligation to, and the rule only matters if discipline of that kind was part of what happened.
Health information follows a separate rule. Under 45 C.F.R. § 164.502(g), a health care provider covered by the federal privacy rule treats a personal representative as the patient. For an adult, that is a person who, under applicable law, has authority to act on the patient's behalf in health care decisions. For an unemancipated minor, a parent with that authority is generally the personal representative, subject to exceptions, including care the minor may lawfully consent to alone. After a death, the executor, administrator or other person with legal authority for the estate is treated as the representative. A hospital, then, may not treat the parent of an injured adult student as the decision-maker on records without legal authority; the student's own authorization, or authority that already exists, is usually the path.
A further avenue is the Office for Civil Rights of the Department of Education, which enforces federal civil rights laws that prohibit discrimination in federally funded programs. Its page How to File a Discrimination Complaint with OCR states that anyone may file a complaint, and that a complainant filing for another person is responsible for securing any necessary written consent, including when a parent files for a student over the age of 18. It states that a complaint must ordinarily be filed within 180 days of the last act of discrimination, with a waiver possible for good cause, or within 60 days after an institutional grievance process ends if the complainant used one. That process concerns discrimination, not every hazing injury, and it is separate from a lawsuit for injuries.
