This project would not have been possible without the generous advice and support of many stakeholders across the state of California. We wish to honor the special expertise of those with lived experience in the criminal justice and behavioral health systems for their valuable and important contributions to the project. Numerous local policymakers from criminal justice, behavioral health, and housing shared their experiences and hopes for policy and data in this area. At the state level, policymakers from many agencies shared their own work collecting and analyzing data in this area, as well as their experiences in sharing data across departments. In particular, we would like to thank the Stepping Up California partners who have provided input on this project throughout its duration. 

This project was a close collaboration between teams from the Council of Criminal Justice and Behavioral Health, The Council of State Governments (CSG) Justice Center, and a small group of expert consultants with decades of experience working on this issue in California. It also builds on important work led by the Mental Health Services Oversight and Accountability Commission (MHSOAC) seeding funding for local data collection and analysis and supporting the stakeholder interviews.
