The Community Engagement in Humanitarian Action Toolkit or CHAT is a compendium of guidance and practical tools that addresses Community Engagement for Social and Behaviour change (CE,SBC) programming needs for natural hazards, conflict and fragile situations, disease outbreaks and epidemics, and complex humanitarian emergencies.

This version of CHAT is an updated resource of the May 2015 version. It is aligned with the latest global frameworks, policies and standards including Core Commitments for Children in Humanitarian Action (CCCs). It also builds on existing community engagement resources, guidance, and tools.
