The national evaluation of the Administration on Children, Youth, and Families' Partnerships to Demonstrate the Effectiveness of Supportive Housing provides an important opportunity to test the effectiveness of the supportive housing model for the child welfare population on a wide scale. This report presents the analysis plan for our 2016 interim findings report, which will measure differences in key outcomes between families that do and do not receive a supportive housing intervention, using administrative data from the child welfare and homeless systems. This analysis also draws on data from an in-person family survey that measures outcomes after one year.
