Student Discipline and Due Process in Illinois Schools

Guide last updated: April 17, 2026. Hazard class: educational outcomes. Civic education by a Concerned Parent.

The short version

Illinois has some of the strongest student-discipline protections in the country. Schools must generally use exclusionary discipline (suspension, expulsion) only as a last resort. Students have procedural due process rights before suspension or expulsion, including notice and an opportunity to tell their side. Students with disabilities have additional protections. School police referrals and student arrests implicate additional rights.

Illinois SB 100 and the framework

Illinois law (Senate Bill 100, now codified in the School Code) requires schools to:

Short-term suspension (1-3 days)

Long-term suspension (4-10 days)

Expulsion (more than 10 days)

Expulsion requires:

Students with disabilities — additional protections

If a student has an IEP or 504 plan, disciplinary action triggers additional rights under IDEA and Section 504:

10-day rule

Removal for more than 10 consecutive school days (or a pattern adding up to more than 10 in a year) is treated as a change of placement.

Manifestation determination

For any proposed removal exceeding 10 days, the IEP team must determine whether the conduct was:

If either is true, the student generally cannot be disciplined for the conduct as if they did not have a disability. Services continue. IEP team may revise the behavior intervention plan.

Continuing services

Students with disabilities who are removed from their placement must continue to receive services enabling them to progress toward IEP goals.

School police and arrests

Chicago Public Schools and many other Illinois districts have police officers assigned to schools (sometimes called "school resource officers"). Students retain constitutional rights:

Illinois's JIDTA (Juvenile Court Act) has specific procedures for school-based arrests. If your child is arrested at school, contact a juvenile defense attorney immediately.

Racial, disability, and gender discrimination in discipline

Illinois law and federal civil rights law prohibit discriminatory discipline. If your student is being disciplined while similarly-situated peers are not, document the disparity. Title VI, Section 504, and IDEA all provide potential remedies.

Illinois's SB 100 specifically requires schools to address racial disparities in discipline.

LGBTQ+ student protections

Illinois's Human Rights Act protects LGBTQ+ students from discrimination in schools. Discipline that is pretextual for punishing a student's gender identity or sexual orientation is actionable.

What to do if your student is facing discipline

  1. Ask for everything in writing. Every notice, charge, decision.
  2. Get the student's school record (you have a right under FERPA).
  3. Document your student's side. Witness names, what they would say, any video, any context.
  4. Review the student handbook and the specific rule your student allegedly violated.
  5. Get an attorney or advocate before the hearing if possible. Many expulsion hearings have life-altering consequences.
  6. Prepare testimony — the student's own account, witnesses, character witnesses, evidence of context (was there bullying, racial tension, untreated mental health issue).
  7. Consider mediation or restorative justice as an alternative if the district offers it.
  8. If the student has an IEP or 504 — demand a manifestation determination meeting before any discipline exceeding 10 days.

After the decision

Expulsion decisions by the school board can be appealed to the Illinois State Board of Education's hearing panel, and potentially to court. The window for appeal is short.
