This guide has developed recommendations based on interviews with specialists within the various sectors. It has been revised by other independent specialists and validated by a group of child protection coordinators and sector specialists. Notwithstanding these efforts, we are aware that inaccuracies may arise as a result of information that was unavailable at the time of drafting, as well as useful methods and resources that warrant inclusion. This is therefore intended to be a living document that will be updated and expanded over time. In a humanitarian response at the national level, all sectors come together for the purposes of MHPSS in the national MHPSS Technical Working Group (TWG). Some knowledge of all sectors may promote more meaningful participation on the part of stakeholders in these MHPSS TWGs. The guide is also a helpful tool for facilitating productive conversations with colleagues from other sectors beyond the MHPSS TWG. Finally, the guidance materials provided may also be useful for case managers faced with the challenge of navigating between sectors to find the best solution for individual children and families.
