California’s CalAIM initiative represents one of the most comprehensive efforts in the nation to transform Medicaid delivery systems to provide more equitable, coordinated, and whole-person care. This UCLA-RAND Interim Evaluation Report summarizes early implementation results from five interrelated evaluation components — Providing Access and Transforming Health (PATH), Global Payment Program, the Medi-Cal Matching Plan Policy for Dually Eligible Beneficiaries (Duals), the Justice-Involved (JI) Reentry Initiative, and Community Supports. Together, these efforts demonstrate the State’s progress toward creating a more integrated Medi-Cal system designed to improve health outcomes, strengthen local infrastructure, and address members’ social and behavioral health needs.

Findings: Taken together, interim findings from these five evaluation components illustrate meaningful progress in advancing CalAIM’s overarching goals. The initiatives collectively demonstrate California’s commitment to integrating medical, behavioral, and social services; strengthening community-based care infrastructure; and promoting equity through targeted investments and policy alignment. The state has successfully expanded participation in new programs, improved the alignment of managed care systems, and piloted innovative approaches to serving high-need populations, including the JI and dually eligible. At the same time, data systems, workforce capacity, and administrative coordination remain key areas for continued development.

The final evaluation will be  published in May 2027.
