This guidebook from the US Department of Housing and Urban Development (HUD) is designed for Continuum of Care (CoC) leaders and stakeholders to use as a direct, hands-on action plan in their efforts to prevent and end youth homelessness. It provides information about emerging program models in the following areas: primary prevention, identification and engagement, emergency and crisis response, and tailored housing and services. This guidebook describes key features and promising practices of these models and potential funding sources to help CoC providers plan, develop, and improve their own youth-appropriate services.
