[4] The IDOC was established in 1970, combining the state's prisons, juvenile centers, and parole services.

The Illinois Department of Corrections uses a three level security designation system that encompasses three points of data.

An offender can be housed at a facility one level lower than his current security classification for a limited period of time if located in the Segregation Unit while a transfer is pending after reclassification.

C grade restricts telephone usage, commissary purchases to cosmetic/legal items, and prohibits many work and school assignments.

In one case this level is assigned to offenders who would otherwise be a low risk when placed in a higher security facility.

For example, Dixon Correctional Center houses the majority of offenders with serious health problems.

The other use for this escape level is where an offender has an outstanding warrant or has absconded from parole or work release during the last 24 months.

Offender identification cards indicate the escape level by utilizing a color coded background.
