When someone you love goes into the Illinois Department of Corrections, you will hear plenty of confident advice that turns out to be wrong, or that describes another state. Illinois does several big things its own way. It abolished parole decades ago, it sorts sentences into truth in sentencing tiers, it calls good time sentence credit and limits who can earn it, and it ends almost every sentence with a supervised release tail that surprises families. Here are the myths I hear most often from Illinois families, and the reality behind each one.
Myth: He will go before the parole board.
Reality: For almost everyone sentenced in the last several decades, there is no parole board deciding release. Illinois abolished traditional parole back in 1978 and moved to determinate sentencing, which means the release date is set by the sentence and the credits the law allows, not by a board vote. The Illinois Prisoner Review Board still exists, but for a determinately sentenced person it does not decide when they get out. It sets the conditions of supervised release, handles credit revocations, and deals with a small number of older cases and special categories. So do not sit waiting on a parole hearing that is not coming.
Myth: Everyone serves half their sentence with good time.
Reality: Only people in the day for day tier serve about half. Illinois truth in sentencing sorts offenses into tiers, and the tier decides how much must be served. Most offenses are day for day, meaning roughly 50 percent. But there is a 60 percent tier, a 75 percent tier, an 85 percent tier for a range of serious violent offenses, and a 100 percent requirement for first degree murder. A person in the 85 or 100 percent tier cannot earn the credits that bring others down toward half. So the very first thing to learn is which tier the specific offense falls into, because it changes the math completely.
Myth: Good time is automatic.
Reality: Illinois calls it sentence credit, and not all of it is automatic. There is statutory day for day credit for eligible people, plus earned discretionary sentence credit, plus program sentence credit for completing things like education, drug treatment, life skills, and similar programs. And it can be taken away. Sentence credit can be revoked for breaking prison rules, and revocations beyond a certain length have to go through the Prisoner Review Board. People in the higher truth in sentencing tiers and those serving natural life cannot earn credit that drops them below their required floor. Credit is real, but it is earned, limited by tier, and revocable.
Myth: When his prison term is done, he is free and clear.
Reality: Almost every Illinois sentence has a mandatory supervised release tail, which Illinois uses in place of the old parole. After the prison portion, the person serves a mandatory supervised release term in the community under supervision, and the length is set by the class of offense. For some serious offenses that supervised term is very long, and for a few it can extend for life. The key point families miss is that this supervised release comes on top of the prison time, not instead of it, so plan for a period of supervision after release.
Myth: He will walk out the day he hits his release date.
Reality: Not always, and this one breaks a lot of hearts. Mandatory supervised release requires an approved host site, meaning a place to live that the department signs off on. A person who reaches their release date but does not have an approved place to go can be held in prison past that date until a suitable site is approved. In other words, a lack of approved housing can keep someone locked up beyond when their time is otherwise up. Lining up approved housing well ahead of the date is one of the most useful things a family can actually do.
Myth: Anyone who takes the classes earns program credit.
Reality: Program sentence credit is real, but eligibility is restricted in Illinois. People convicted of offenses that require serving 85 or 100 percent generally cannot earn program credit to cut their time, although they may still be allowed to participate in the programs. People with sex offenses can typically only earn credit while they are in approved treatment. So before assuming that finishing a program will move a release date, confirm whether the specific offense even allows program credit to count. The classes are worthwhile either way, but the credit is not universal.
Myth: The Prisoner Review Board decides when he gets out.
Reality: For a determinately sentenced person, which means essentially everyone sentenced since 1978, the Board does not set the release date. That date comes from the sentence and the credits the law allows. What the Prisoner Review Board actually does is set the conditions of mandatory supervised release, rule on longer credit revocations, decide certain medical release requests, handle the small group of old indeterminate cases and some youthful offender situations, and make clemency recommendations to the Governor. Aiming your hopes at a board that is not deciding release just wastes precious time.
Myth: I can call the prison to find out if I am on his visitor list.
Reality: Illinois staff will not tell you over the phone whether you are on the approved visitation list. The only reliable way to find out is to write a letter to your person and ask them directly. On top of that, the incarcerated person can generally only update their visitation and phone lists about once a month, so getting yourself added is not instant. Build in time, and confirm in writing before you make plans to travel for a visit.
Myth: I can show up to visit any day that works for me.
Reality: Illinois visiting is more limited than families expect. In person visiting generally runs on weekdays during set daytime hours, with a capped number of visits per month, and video visits through the state's vendor have to be scheduled in advance, commonly at least seven days ahead. Lockdowns can suspend visits with little notice. There is no dropping by whenever it is convenient, so always confirm the facility's current schedule and your approved status before you go.
Myth: Calls are cheap or free now.
Reality: Illinois recently changed its prison phone vendor, and families had to set up brand new accounts with the new provider, which caught a lot of people off guard. But calls remain a paid, prepaid service, and video visits carry a per session fee as well. Unlike a few states that made prison phone calls free, Illinois families should still budget for the cost of staying in touch and set up the account early so they do not miss the first calls.
The bottom line
Illinois runs on tiers and tails. The truth in sentencing tier decides how much of the sentence is actually served, sentence credit is earned and limited rather than automatic, and a mandatory supervised release period follows the prison term, sometimes held up by the need for approved housing. The recurring theme is that release is governed by law and credits rather than a parole board, and that very little is automatic or quick. The families who do best learn the exact tier, push the programs that earn credit when the offense allows it, line up an approved host site early so release is not delayed, get added to the visitor list in advance, and budget for communication costs. This is general information, not legal advice. For a specific sentence calculation or release question, the department, the Prisoner Review Board, or an attorney is the right authority.
