​​​​​​​​​​​​​The Pennsylvania Criminal Justice Data Dictionary (CJDD) is a collaborative product of several Commonwealth adult criminal justice agencies, specifically the Administrative Office of Pennsylvania Courts (AOPC), the Department of Corrections (DOC), the Pennsylvania Board of Probation and Parole (PBPP), the Pennsylvania Commission on Crime and Delinquency (PCCD), and the Pennsylvania Commission on Sentencing (PCS).

Coordinated by PCCD, this data dictionary contains data elements and their individual agency-specific definitions, that have been developed for the purpose of electronically documenting the vital criminal justice data that agencies are capturing. The CJDD provides the common language necessary for facilitating an enhanced sharing, understanding, and communication of what data is available within the Commonwealth adult criminal justice community. Identifying, cataloging, and defining these data elements supports the Commonwealth’s ability to conduct meaningful criminal justice research, while also facilitating the external research opportunities for the Commonwealth’s academic partners.
