Students shall not be released from school in the care of a person other than a person with parental authority with respect to the student (parent, guardian, case worker, foster parent or person acting in loco parenti), or other than a person designated by the person with parental authority with respect to the student, except with the permission of the principal or designee. No student shall be released from school based on a telephone call or electronic means unless the principal or designee can authenticate that the person authorizing the release is a person with parental authority with respect to the student. Nothing in this policy shall prevent the school from sending home a student who is ill.
