Supplemental Sentence Credit (“SSC”) refers to credit of up to 180 days on an offender’s incarceration that can be issued as a result of an offender’s good conduct. This credit is at the sole discretion of the Director of the Department of Corrections or his designee. Similar to Statutory Sentence Credit and Program Sentence Credit, offenders may lose SSC based on their behavior while in custody.

For an offender to be eligible for an award of SSC, first and foremost, he or she must have served more than 60 days in IDOC custody and be serving a sentence for offenses that are not excluded from an award pursuant to Section 3-6-3(a)(3) of the Code of Corrections (730 ILCS 5/3-6-3(a)(3)). Additionally, some offenders, by the nature of their current commitment offenses, will only be eligible for up to 90 days of SSC pursuant to Section 3-6-3(a)(3) of the Code of Corrections.

There are additional administrative rule (20 Ill. Adm. Code 107.210) requirements that must be met in order for an offender to be eligible for an award of SSC. The offender:

  • must not be subject to review under the Sexually Violent Person’s Act,

  • must not have been found guilty of a 100 level disciplinary offense (violated while in custody) under 20 Ill. Adm. Code 504,

  • must not have any pending criminal charges committed during the current incarceration,

  • must not have been returned to the Department for a violation of his or her parole or mandatory supervised release during their current incarceration,

  • must not have voluntarily quit or have been terminated for disciplinary reasons from a boot camp program,

  • if recommended by a court, must have completed substance abuse treatment or been waived from the requirement by the Department, and

  • must have completed mandatory sex offender treatment (if necessary) or been waived of the requirement by the Department (if applicable).

It is important to note that even if an offender is potentially eligible for an award of SSC, the offender should not and does not have an outright expectation to receive an award.

Potentially eligible offenders should have no expectation of receiving an SSC award because, beyond the eligibility requirements noted above, the Department has the discretion to consider numerous other factors before finding an offender suitable for an award of SSC. As such, the Department may examine and consider numerous things including, but not limited to:

  • The offender’s complete master record file, including, but not limited to, facts and circumstances of the holding offense(s), disciplinary records, and reports or recommendations made concerning the offender.

  • The offender’s risk assessment analysis (if available).

  • The offender’s history of conviction for violent crimes, as defined by the Rights of Crime Victims and Witnesses Act [725 ILCS 120].

  • The offender’s assignment performance while in the custody of the Department.

  • The offender’s educational or program performance and achievements while in the custody of the Department.

  • The offender’s service to the Department, community, or State.

  • The heroic action of the offender, such as saving the life of an employee or other offender.

  • The offender's potential for rehabilitation.
