This document outlines the expectations, terminology, and key concepts regarding a training on combating commercial sexual exploitation of children in tourism. It discusses understanding the phenomenon, identifying victims and perpetrators, and ways to tackle the issue through tourism businesses, NGOs, states, police, and individual action. Communication strategies are highlighted as important tools to address the problem and raise awareness among travelers, the tourism industry, and local communities in source and destination countries.
