The Children’s Bureau, within the Administration for Children and Families, funded a multi-phase grant program to build the evidence base on what works to prevent homelessness among youth and young adults. This initiative is called the Youth At-Risk of Homelessness (YARH). This issue brief looks at methods YARH grantees used to engage youth in the development of new comprehensive service models intended to reduce homelessness among youth who are in or formerly in foster care. The brief provides samples of YARH grantees activities. (abstract modified)
