The bill aims to enhance data collection and reporting within the Massachusetts criminal justice system by establishing a Data Governance Council (DGC) and mandating the submission of annual reports by the Justice Reinvestment Policy Oversight Board. This Board, created in 2018, is responsible for monitoring the implementation of justice reinvestment policies, focusing on the standardization and public availability of data from various criminal justice agencies, including the Probation Service and the Department of Correction. Key initiatives include the development of a cross-agency tracking system using a unique state identification number, the public accessibility of data through an application programming interface (API), and standardized reporting on recidivism rates and demographic information. The legislation emphasizes the importance of accurate data reporting, particularly regarding race and ethnicity, by standardizing definitions and collection methods across agencies. It requires the Secretary of Public Safety to track and report recidivism rates by demographics annually, while also highlighting the progress made in creating public dashboards for recidivism and other key indicators. The bill underscores ongoing efforts to improve data quality and integration, ensuring that the criminal justice system in the Commonwealth remains transparent, accountable, and informed by data-driven insights for policy and program development.
