DCJ provides assistance to state and local agencies in the criminal justice system.

DCJ provides assistance by analyzing policy, conducting criminal justice research, managing programs and administering grants. 


Enabling Legislation

The Colorado legislature created the Division of Criminal Justice (DCJ) to "...improve all areas of the administration of criminal justice in Colorado, both immediately and in the long term, regardless of whether the direct responsibility for action lies at the state level or with the many units of local government" (24-33.5-501 C.R.S. 1973 as amended).

DCJ’s Mission

Our mission is to improve the safety of the community, the quality of services to crime victims, and the effectiveness of services to offenders.  We accomplish this by analyzing policy, conducting criminal justice research, managing programs, and administering grants.
