(1) Consent means that:

(a) The parent has been fully informed of all information relevant to the activity for which consent is sought, in his or her native language, or other mode of communication;

(b) The parent understands and agrees in writing to the carrying out of the activity for which consent is sought, and the consent describes that activity. This includes a list of any records that will be released, and to whom they will be released, or records that will be requested and from whom; and

(c) The parent understands that the granting of consent is voluntary on the part of the parent and may be revoked at any time.

(2) If a parent revokes consent, that revocation is not retroactive. This means that it does not undo an action that occurred after consent was given and before the consent was revoked.

(3) If the parent revokes consent in writing for their child's receipt of special education services after the student is initially provided special education and related services, the school district is not required to amend the student's education records to remove any references to the student's receipt of special education and related services because of the revocation of consent.
