Within 10 days after completing an investigation of alleged physical or sexual abuse under this Act, if the report is indicated, the Child Protective Service Unit shall send a copy of its final finding report to the school that the child who is the indicated victim of the report attends. If the final finding report is sent during the summer when the school is not in session, the report shall be sent to the last school that the child attended. The final finding report shall be sent as "confidential", and the school shall be responsible for ensuring that the report remains confidential in accordance with the Illinois School Student Records Act. If an indicated finding is overturned in an appeal or hearing, or if the Department has made a determination that the child is no longer at risk of physical or sexual harm, the Department shall request that the final finding report be purged from the student's record, and the school shall purge the final finding report from the student's record and return the report to the Department. If an indicated report is expunged from the central register, and that report has been sent to a child's school, the Department shall request that the final finding report be purged from the student's record, and the school shall purge the final finding report from the student's record and return the report to the Department.
