Purpose
The purpose of 501 CMR 18.00 is to establish data collection and reporting standards for
Criminal Justice Agencies to enable the submission of data by Criminal Justice Agencies
including, but not limited to, the Department of Correction, Houses of Correction, and county
jails, to capture and report information on their populations and to report information relative to
recidivism rates.

Criminal Justice Agencies by:
(a) Defining the data to be collected; and
(b) Developing a data warehouse that is accessible to Criminal Justice Agencies and in an
anonymized format to the public.
To facilitate the implementation of 501 CMR 18.00, the Executive Office of Public Safety
and Security (EOPSS) shall enter into an appropriate Memorandum of Understanding (MOU)
with the Trial Court as specified in 501 CMR 18.08.
