The Partnerships to Demonstrate the Effectiveness of Supportive Housing, funded by the US Department of Health and Human Services, was designed to explore the effects of providing housing and intensive services to high-need families in the child welfare system. Demonstration sites created new service delivery structures to accomplish their goals, worked more intensively than ever with partner agencies, and changed agency policies and procedures to make the demonstration successful. Most sites also found ways to sustain effective practices once their demonstration-funded projects ended. This report examines what the sites accomplished, including changes in child welfare agency practice and ongoing financial support. Most sites have been able to maintain the key policies and practices developed during the demonstration to more effectively target and support families.
