Prevent Trafficking in Our Schools Act This bill directs the Department of Homeland Security, at the request of the Department of Education (ED), to develop educational materials that ED may use to provide teachers, school leaders, and other personnel of elementary and secondary schools (covered educational personnel) with training in human trafficking awareness and techniques for identifying victims of human trafficking in elementary and secondary schools. The bill sets forth matters that the educational materials must address and requires that such materials emphasize that covered educational personnel who notice indicators of potential human trafficking should contact law enforcement and should not attempt to engage in counter-trafficking operations.
