The bill outlines new requirements for the Massachusetts Department of Correction regarding the collection and reporting of quarterly corrections data. It introduces specific categories for counting admissions and releases, including "Pre-Trial/Detainees" and "Criminally Sentenced," which encompass various subgroups such as individuals awaiting trial, those held on bail, and re-admissions due to parole or probation violations. Additionally, the bill establishes a "Caseload Snapshot" and a "Recidivism" section, detailing how to classify and report on individuals in custody, including those under community supervision and civil commitments.

Furthermore, the bill emphasizes the importance of accurate counting rules for different populations, ensuring that all relevant groups are included in the data collection process. It specifies the need for clear definitions and categories to enhance the understanding of the corrections system's demographics and recidivism rates. The new legal language aims to improve transparency and accountability within the Massachusetts correctional system by providing a comprehensive framework for data reporting.
