Following a review of statistics on the national incidence of missing children, the handbook defines three classifications of missing children: runaways, parent abductions, and abductions by unknown persons. A discussion of the measures that schools can take to help prevent child abductions includes the tracking of students. In addition to personal and medical histories, a comprehensive student tracking system should contain the student's current address and phone number, identification of the student's legal guardian, validation of where the student previously attended school, and a photograph of the student that is no more than one year old. Other preventive steps include the identification of students through photographs, fingerprinting, dental microchips, videotapes, and ID bracelets. A comprehensive school program must also include means for keeping parents informed about measures for preventing child abductions. The handbook lists rules that children should learn if they are to be prepared to recognize and resist an abduction attempt. Other sections of the handbook discuss school measures designed to prevent abductions from school premises, how to report a child missing, how to report the discovery of a missing child, and the reintegration of an abduction victim into the classroom. 5 references and appended lists of U.S. corporations involved in the problem of missing children, organizations with information on missing children, and resources for teachers and parents
