This document provides guidance on planning a whole school training day focused on education for sustainable development (ESD). It recommends establishing a planning committee comprising the head teacher, ESD coordinators, and representatives from the whole school. The committee should determine topics like content, justification, strategies and activities for the training. They should also identify external support available and a timeline including full-day sessions, after-school sessions, and events involving students, parents and community members to engage the entire school community. The document concludes by outlining an activity for schools to create posters visually depicting their ESD training day plans.
