The U.S. Department of Education says the trafficking of children for commercial sex and forced labor is a big enough problem that teachers, bus drivers and other school staff should help by identifying and reporting suspected victims.

The agency has released a guide, Human Trafficking in America's Schools, that describes how to identify victims and what to do about it.

“School administrators and staff need to be aware that cases of child trafficking are being reported in communities throughout the nation,” the guide says. “No community—urban, rural, or suburban—school, socioeconomic group, or student demographic is immune.”
