This guide from the Child Welfare Information Gateway outlines affordable housing and homelessness services and how child welfare professionals can collaborate with those systems to help families. Although primarily for child welfare professionals, the information may help housing and homelessness services providers understand the needs and concerns of child welfare-involved youth and families and what services are available to them. The guide features grantee programs focused on child welfare and housing collaboration that were part of the Partnerships to Demonstrate the Effectiveness of Supportive Housing for Families in the Child Welfare System (SHF) and Youth At-Risk of Homelessness (YARH) grant clusters.
