Illinois and New York City followed a public agency model, which maintains the traditional management and service-delivery structure while incorporating managed care practices in its own practices or contracts with service providers. Both initiatives involve public agencies that maintain their previous management and service-delivery structure while incorporating financial incentives into their contracts with foster care agencies. In both cases, the public agencies closely monitor the agencies' performance and outcomes, and financial incentives are based on analysis of data on permanency outcomes. In Colorado’s Boulder County initiative (as well as in other managed care counties in Colorado), the public agency has joined with other public child-serving agencies to use managed care principles in case management and service delivery. Oklahoma also follows a public agency model in its capitated contracts with providers.
