The parent or guardian of a student or the eligible student shall provide a signed and dated written consent before an educational agency or institution discloses personally identifiable information from the student records, other than directory information, except as provided in Regulation .19 of this chapter. Whenever written consent is required, a local school system or educational institution may presume that the parent or guardian of the student or the eligible student giving consent has the authority to do so unless the system or institution has been provided with evidence that there is a legally binding instrument or a State law or court order governing such matters as divorce, separation, or custody, which provides to the contrary. The written consent required by §A of this regulation shall be signed and dated by the parent or guardian of the student or the eligible student giving the consent, and shall include: A specification of the records to be disclosed; The purpose or purposes of the disclosure; and The party or class of parties to whom the disclosure may be made. The local school system may develop a wide range content statement for the release of all data. When a disclosure is made pursuant to §A of this regulation, the local school system or educational institution shall, upon request, provide a copy of the record which is disclosed to the parent or guardian of the student or the eligible student, and to the student who is not an eligible student, if so requested by the student's parent or guardian.
