This document outlines principles for schools and external visitors to follow when delivering drug education programs in partnership. It recommends that visitors be aware of effective drug education strategies, avoid inappropriate content, and reflect on sessions. Schools should negotiate content with visitors, ensure visitors understand school policies, and brief visitors on any student sensitivities. Teachers should be present during sessions, assess learning, and follow up on any issues. The goal is to have a positive experience that links to the school's broader drug education curriculum.
