CrOss System Technical Assistance for Retaining Staff (COSTARS) is designed to help child welfare supervisors support the case workers and family peer mentors on their teams so that they can deliver programs like Ohio START to families affected by substance use disorder. COSTARS will deliver personalized coaching support to child welfare supervisors by a pair of coaches: one with child welfare expertise and one with lived recovery/child welfare experience. Supervisors will participate in a group training that emphasizes supportive supervision practices, and then receive up to two years of ongoing coaching support that involves monthly calls, and written feedback based on recorded supervision sessions.
Implementation as Usual includes training on the model, monthly technical assistance calls focused on model fidelity, regular audits of programmatic data, and monthly group calls with implementers from across the state.
