Final answer:
Consent to disclose a student's PII or education records must come from a parent/guardian until the student graduates or is discharged from the DOE, regardless of the student's age.
Step-by-step explanation:
Consent to disclose a student's Personally Identifiable Information (PII) or education records generally requires the consent of a parent or guardian until the student graduates or is no longer enrolled in the Department of Education, regardless of their age. This is in accordance with the Family Educational Rights and Privacy Act (FERPA), which protects the privacy of students and prohibits the disclosure of their educational records without consent. The intention is to ensure that the privacy and confidentiality of a student's information are safeguarded.
