The bill amends Massachusetts General Laws, specifically Chapter 126, Section 40, to enhance the reporting requirements for jails and houses of correction. It introduces a new section titled "Overview of Quarterly Population Report for the Individual Massachusetts Sheriffs' Offices," which requires sheriffs to compile and submit quarterly reports containing various data points for each inmate, such as probation central file numbers, state identification numbers, race and ethnicity, and offense-based tracking numbers, while ensuring that no identifying information about individual inmates is included. The bill also establishes new definitions for key terms and notes that certain data points, like case disposition and bail information, are managed by the Trial Court rather than the Sheriffs' Offices.

Additionally, the bill focuses on improving rehabilitation programs within the Worcester correctional facility, emphasizing the importance of structured programming such as Anger Management, Relapse Prevention, and Substance Use Education. It categorizes participants by race and ethnicity and tracks their participation status, including outcomes like administrative removal or release. The bill aims to create a supportive framework for offenders, promoting personal growth and accountability while addressing the specific needs of diverse populations within the correctional system. Overall, the legislation seeks to enhance operational efficiency, transparency, and the effectiveness of rehabilitation efforts, ultimately contributing to lower recidivism rates and improved community safety.
