The Chicago Family Case Management Demonstration provided vulnerable public housing residents from two Chicago Housing Authority developments with intensive case management services, transitional jobs, financial literacy training, and relocation counseling. The Demonstration was remarkably successful in implementing a wraparound service model. The lead service provider kept residents highly engaged even as they relocated with vouchers or to mixed-income housing. Participants perceived improvements in service quality and delivery, and providers felt more effective and engaged. The additional costs for the intensive services were modest, suggesting that it would be feasible to take a carefully targeted intensive service model to scale.
