Under the Illinois juvenile sentencing guidelines set out in the Juvenile Court Act of 1987, a judge who finds a minor delinquent can order supervision, probation, conditional discharge, community service, restitution, treatment, or commitment to the Illinois Department of Juvenile Justice. Every option is chosen with rehabilitation as the governing goal, and the statute pushes judges away from confinement whenever a less restrictive sentence fits the offense and the young person.
The Sentencing Options a Judge Can Order
Once a juvenile court adjudicates a minor delinquent, Section 5-710 of the Juvenile Court Act lays out the disposition choices. The judge matches the sentence to what the young person actually needs, not just the label on the charge.
Supervision
Supervision is the lightest outcome and the one most first-time, low-level cases end with. The court sets conditions, and if the minor completes them, the case is dismissed with no formal adjudication of delinquency. Nothing more happens, and no delinquency finding attaches to the minor’s record.
Probation and Conditional Discharge
Probation is the most common sentence when the court does adjudicate the minor delinquent. The minor goes home to a parent or guardian under conditions the judge sets: check-ins with a probation officer, school attendance, curfews, counseling, or substance abuse treatment are typical. Probation can run up to five years or until the minor turns 21, whichever comes first. A minor found delinquent for first degree murder must receive at least five years of probation.1Illinois General Assembly. Illinois Code 705 ILCS 405/5-715 – Duration of Probation
Probation is required, not optional, in certain cases. If a minor is adjudicated delinquent for first degree murder, a Class X felony, or a forcible felony but not committed to IDJJ, the court must place them on probation.2Illinois General Assembly. Illinois Code 705 ILCS 405/5-710 – Kinds of Sentencing Orders Conditional discharge works much like probation but drops the ongoing supervision of a probation officer.
Community Service and Restitution
The court can order community service hours or require the minor to compensate the victim for actual losses. Certain offenses trigger mandatory community service; a minor found delinquent for criminal defacement of property, for instance, must perform it. These sentences focus on repairing harm rather than confining the young person.
Commitment to the Department of Juvenile Justice
For serious offenses, the court can commit the minor to the Illinois Department of Juvenile Justice. Commitment terms are indeterminate. There is no fixed release date in the statute; instead, the commitment ends when the minor turns 21 or when the sentence an adult would serve for the same offense would expire, whichever comes first.2Illinois General Assembly. Illinois Code 705 ILCS 405/5-710 – Kinds of Sentencing Orders
Other Tools
The court has additional options for shaping a sentence. It can order a substance abuse assessment and require the minor to participate in treatment at the recommended level. It can suspend the minor’s driver’s license. In some circumstances it can order partial or complete emancipation. The point of the flexibility is to let the judge address the circumstances behind the behavior instead of picking from a rigid menu.
When Commitment to IDJJ Is Off the Table
Illinois law places real restrictions on which minors can be sent to IDJJ, even when the offense is a felony. A juvenile cannot be committed for anything that would not be illegal if an adult did it. The court also cannot commit a minor to IDJJ for several lower-level felonies when charged as Class 4: criminal trespass to a residence, criminal damage to property, disorderly conduct, and obstructing justice. For Class 3 or Class 4 felony drug offenses, commitment is unavailable unless the minor has violated probation at least three times by substantially failing to comply with court-ordered treatment.2Illinois General Assembly. Illinois Code 705 ILCS 405/5-710 – Kinds of Sentencing Orders
These restrictions mean many felony adjudications resolve with probation, treatment, or other community-based sentences even when the underlying offense sounds serious.
How Long a Juvenile Sentence Can Last
Juvenile jurisdiction generally covers minors under 21, though most cases involve youth under 18. All delinquency proceedings automatically terminate when the minor turns 21, with narrow exceptions for extended jurisdiction covering habitual juvenile offenders. Commitment to IDJJ ends at 21 or when the equivalent adult sentence would have expired, whichever comes first.2Illinois General Assembly. Illinois Code 705 ILCS 405/5-710 – Kinds of Sentencing Orders
For 17-year-olds, jurisdiction depends on the offense. Misdemeanor charges go through juvenile court. Felony charges are routed to adult criminal court by default. The floor for secure detention in a delinquency matter is age 10.3FindLaw. Illinois Code 705 ILCS 405/5-410 – Non-secure Custody or Detention
What the Judge Weighs
Juvenile court judges have wide discretion, but that discretion is shaped by specific factors. The seriousness of the offense matters most, though the statute and court practice require judges to look past the charge itself.
Delinquency history carries weight. First-time offenders are far more likely to get supervision or probation; repeat offenses push the court toward more restrictive sentences. Age and developmental stage factor in, with courts recognizing that younger adolescents process consequences differently than older teens.
Family stability and community ties matter in practical ways. A minor with a supportive home and adults willing to participate in a rehabilitation plan is a stronger candidate for probation than one returning to a chaotic or dangerous situation. Judges also review psychological evaluations and mental health assessments to identify treatment needs the sentence should address.
Many Illinois courts use the Juvenile Risk Assessment, an evidence-based tool developed at the University of Cincinnati, to standardize these decisions. The assessment scores youth across seven domains: juvenile justice history, family and living arrangements, peer influences, education or employment, prosocial skills, substance abuse, and mental health. Probation officers use the results to target the specific risk factors driving delinquent behavior.
When a Case Leaves Juvenile Court for Adult Court
Juvenile sentencing guidelines only apply as long as the case stays in juvenile court. Illinois has three pathways for moving a case into the adult system, and each changes the sentencing picture entirely because a transferred minor faces adult sentencing ranges, adult incarceration, and a permanent criminal record.
Automatic Transfer
The most rigid pathway applies to minors who were at least 16 at the time of the offense and are charged with first degree murder, aggravated criminal sexual assault, or aggravated battery with a firearm where the minor personally discharged the weapon.4Illinois General Assembly. Illinois Code 705 ILCS 405/5-130 – Excluded Jurisdiction Juvenile court jurisdiction is excluded, and any other charges arising from the same incident follow into adult court. No hearing is required.
Presumptive Transfer
A rebuttable presumption of transfer applies when the State’s Attorney seeks to prosecute a minor who is at least 15 for a forcible felony, the minor has a prior forcible felony adjudication or conviction, and the current offense was committed in furtherance of organized gang activity. If the court finds probable cause for those allegations, the burden shifts to the minor to prove by clear and convincing evidence that they are amenable to juvenile court treatment.5Illinois General Assembly. Illinois Code 705 ILCS 405/5-805
Discretionary Waiver
The broadest transfer mechanism lets the State’s Attorney petition for adult prosecution of any minor who was at least 13 at the time of the offense. The juvenile court holds a hearing and evaluates the minor’s age, prior delinquency and criminal history, abuse or neglect history, mental health and educational background, involvement in the child welfare system, and the seriousness of the offense.5Illinois General Assembly. Illinois Code 705 ILCS 405/5-805 The court gives greater weight to the seriousness of the alleged offense and the minor’s prior record than to other factors. Transfer is permitted only when the court finds it is not in the best interests of the minor or the public to proceed in juvenile court.6Office of Juvenile Justice and Delinquency Prevention.

What Happens to the Record After Sentencing
A sentence is not the whole story. Illinois has moved aggressively toward clearing juvenile records, and the system now operates on multiple tracks.
Automatic Expungement
For the lowest-level contacts, expungement happens without any petition. Law enforcement records from events before a person’s 18th birthday are automatically expunged if at least one year has passed since the arrest, no delinquency petition or criminal charges were filed, and six months have passed without a subsequent arrest. Court records are automatically expunged upon a dismissal, a finding of not delinquent, or successful completion of a supervision order. Records from adjudications equivalent to a Class B or Class C misdemeanor or a petty offense also qualify upon successful completion of the sentence.
For more serious delinquency adjudications that are not disqualified, automatic expungement kicks in two years after the case closes, provided no delinquency or criminal proceeding is pending and the person has not had a subsequent adjudication or conviction. Governor Pritzker signed legislation in 2024 (Public Act 103-0787) that further streamlined the process, requiring the juvenile court judge to schedule an automatic expungement date when a minor’s sentence ends or when the court enters a commitment order.7Illinois General Assembly. Bill Status for SB 3463
Petition-Based Expungement
When automatic expungement does not apply, the person can petition the court in the county where they were sentenced. Juveniles who were committed to IDJJ must wait at least five years after their commitment ended, including any aftercare term, before petitioning.8Illinois Department of Juvenile Justice. Expungement
Records That Cannot Be Expunged
Some records are permanently excluded. A plea agreement or guilty finding involving first degree murder or a felony sex offense cannot be expunged. Traffic offenses, including DUI, and petty offenses are also excluded.8Illinois Department of Juvenile Justice. Expungement Automatic expungement provisions do not cover traffic, boating, or fish and game violations either.
Once a record is expunged, it is physically destroyed or returned to the individual, and the person’s name is removed from any official index. No private or public employer within Illinois can ask about expunged juvenile records or use them in a hiring decision.
