This Handbook is designed for situations where the international community is formally engaged with the humanitarian response and where the cluster system has been activated. The Handbook may, however, also be useful for contexts where there is no cluster approach. Although the Handbook is primarily addressed to child protection coordination teams, which may include coordinators, co-leads and information managers, the guidance is equally valid for all members of the child protection coordination group, including national and international nongovernmental organizations (NGOs), government representatives and other members, who seek to achieve an effective and coordinated response.
