Supplemental Sentence Credit 


SPRINGFIELD - February 22, 2013 - The Illinois Department of Corrections is implementing the supplemental sentence credit program, which will strengthen public safety and safety inside state prisons. The new program will allow the department to, after comprehensive review, award up to 180 days of sentence credit to statutorily eligible offenders who demonstrate positive behavior in custody and show a potential for rehabilitation.

The program was created by SB 2621, sponsored by Sen. Kwame Raoul (D- Chicago) and Rep. Barbara Flynn Currie (D- Chicago), which passed both houses with bipartisan support and has been endorsed by many criminal justice organizations, including the John Howard Association.

Offenders must have served at least 60 days within IDOC to be eligible for credit, and inmate files will go through multiple levels of review before an award is determined.

The file review includes a comprehensive examination of an offender’s current holding offense(s) as well as any criminal history and disciplinary record. Programming, educational courses, assignments and any other supporting evidence that could show an offender’s progression towards rehabilitation will also be reviewed. IDOC will also have the right to revoke credit if an inmate demonstrates negative or violent behavior, which was not permitted under previous programs.

Under the law, the department must notify local authorities at least two weeks prior to an inmate’s parole if the offender received supplemental sentence credit at any point during incarceration. The department will also post this information on its Community Notice page on the IDOC website at:

Inmates will be notified if and when they are awarded any supplemental sentence credit. The projected parole date on the offender search database on the IDOC website will also be updated to reflect any credit awarded. Due to the comprehensive review process, the department will not be able to inform those who call the agency whether or not an inmate will be eligible for credit.
