Criminal Justice Programs in Illinois: Schools, Pay and Hiring Rules
Updated October 6, 2026
Eighty-five Illinois colleges offer criminal-justice-family programs, per U.S. Department of Education data, including 53 with associate degrees and 31 with bachelor’s. Every Illinois officer must finish ILETSB-approved basic training and pass the state certification exam, but each agency sets its own education rules. Illinois patrol officers earned a $100,520 median in May 2025 (BLS).
Chicago recorded 416 homicides in 2025, its fewest since 1965 and its fourth straight annual decline, after a drop that ran from 2016 through 2019 and a pandemic-era spike. Chicago’s police department remains under a federal consent decree that sets how its recruits are hired and trained. That’s the Illinois you’d be walking into: falling violence, heavy oversight, and patrol pay that runs about $24,000 above the national median.
How Do You Get Into Criminal Justice Work in Illinois?
Two separate sets of rules decide whether you can wear a badge in Illinois, and it pays to keep them apart. The first is statewide: Illinois law-enforcement officers generally must complete basic training approved by the Illinois Law Enforcement Training and Standards Board (ILETSB) and pass the state certification exam to become certified to serve as officers in the state. That applies whether you’re hired in Chicago, Springfield or a village of 2,000.
The second set belongs to the agency. Each department decides its own education, age and experience minimums for hiring, and the gap between them is wide. Find the agency you actually want and read its current posting before you sign up for tuition.
Chicago currently requires one of the following:
- 60 semester hours of college credit: From an accredited college or university, in any subject.
- 30 semester hours plus one year of continuous active military duty: The combination route for veterans who started college.
- Two years of continuous active military duty: No college credit required on this route.
Many suburban and downstate departments ask for a high school diploma or GED and pay more for a degree. The Illinois State Police sets its own education and experience minimums, which have changed more than once in recent years, so read the current ISP posting before you plan coursework around it.
Outside policing, the degree rules are firmer. Prosecutors need a law degree and an Illinois law license. Illinois probation and court-services officers must meet Administrative Office of the Illinois Courts (AOIC) minimum qualifications, including a bachelor’s degree, and individual circuits may add requirements of their own. Paralegal work opens with an associate degree or an approved paralegal program. The Attorney General’s office, for example, requires one of those plus experience and prefers a bachelor’s.
Where to Study Criminal Justice in Illinois
Per U.S. Department of Education data, 85 Illinois institutions offer at least one program in the criminal justice family: criminal justice and corrections, legal support services, homeland security, fire protection, and security science and technology. None of the 85 is a distance-only school, so every one has a physical Illinois campus. Fifty-seven are public, 23 are private nonprofit, and 5 are for-profit. Fifty-one are two-year colleges, which is why an associate degree is the cheapest way into the field here.
Each school is counted once per credential level it offers, so the rows below add up to more than 85.
| Credential Level | Illinois Institutions Offering It |
|---|---|
| Associate degree | 53 |
| Undergraduate certificate | 46 |
| Bachelor’s degree | 31 |
| Master’s degree | 14 |
| Graduate certificate | 3 |
| Post-baccalaureate certificate | 2 |
| Doctoral degree | 1 |
At the top of that ladder, the University of Illinois Chicago is the one Illinois institution federal data lists with a criminal justice doctorate. Master’s programs are spread across public universities from Chicago State and Governors State to Southern Illinois University’s Carbondale and Edwardsville campuses, plus private schools such as Loyola University Chicago and Lewis University. Program lists change faster than federal reporting does, so check enrollment, format and admission requirements with the school before you apply.

What Do Criminal Justice Jobs in Illinois Pay?
Illinois pays above the national line in nearly every criminal justice job. The table also shows where the openings won’t be.
| Career | Illinois Median Salary (May 2025) | Illinois Job Growth (2024-34) |
|---|---|---|
| Police and Sheriff’s Patrol Officers | $100,520 | 5.2% |
| Detectives and Criminal Investigators | $91,190 | 2.9% |
| Paralegals and Legal Assistants | $63,670 | 2.0% |
| Lawyers, including Prosecutors | $160,800 | 5.9% |
| Correctional Officers and Jailers | $79,190 | -4.6% |
| Probation Officers and Correctional Treatment Specialists | $74,390 | 5.6% |
Illinois figures are from the May 2025 US Bureau of Labor Statistics state Occupational Employment and Wage Statistics estimates. National career profiles: Police and Sheriff’s Patrol Officers and Detectives and Criminal Investigators, Paralegals and Legal Assistants, Lawyers, Correctional Officers and Jailers, and Probation Officers and Correctional Treatment Specialists. Long-term (2024-34) job growth projections from the US Department of Labor-sponsored resource, ProjectionsCentral. Figures reflect state-level data, not school-specific information. Conditions in your area may vary. Data accessed October 2026.
For a plain-language rundown of what each job involves day to day, O*NET publishes a profile for every occupation in the table.
Law Enforcement
The Illinois State Police patrol the highways, county sheriffs run the jails and patrol unincorporated land, and city and village departments police everything else. As of the May 2025 BLS data, Illinois patrol officers earn a $100,520 median against $76,210 nationally. Expect to earn it on nights, weekends and holidays for your first several years.
Private investigation is a separate track with its own license. In Illinois, private detectives are licensed by the Illinois Department of Financial and Professional Regulation (IDFPR), and the eligibility rules and exam are specific to this state. The BLS wage file this site uses doesn’t include private investigators, so there’s no Illinois figure to publish here. The private investigator guide covers the general licensing route.
The Courts
Once someone’s arrested, the case moves to a circuit court, where a county state’s attorney prosecutes it with paralegals and legal assistants doing much of the document work. Lawyers top the table at $160,800, but that figure covers private practice too, and public prosecutors usually start well below it. Paralegal growth is the slowest in the table at 2.0% through 2034.
Corrections
This is the honest number on the page. Illinois projects a 4.6% decline in correctional officer jobs through 2034, the only negative figure in the table. Shrinking doesn’t mean closed, though. ProjectionsCentral still projects about 1,060 openings a year from retirements and turnover, and the work pays a $79,190 median against $58,940 nationally. Probation is the growth side of corrections, projected at 5.6% over the same period.
What’s Changed in Illinois Criminal Justice?
Chicago’s reputation for gun violence drove a decade of reform, and three of those changes shape the jobs above.
The first is the federal consent decree. The Chicago Police Department entered it in 2019, and it covers use of force, recruitment and hiring, training and other areas under federal-court and independent-monitor oversight. A CPD recruit today trains under those court-supervised standards. It built on earlier efforts such as the department’s 2016 Community Policing Advisory Panel.
The second is the end of cash bail. In 2017 the Illinois Supreme Court created a Commission on Pretrial Practices to study how release decisions were made. Illinois eliminated cash bail on September 18, 2023, under the Pretrial Fairness Act, part of the SAFE-T Act, and was the first state to do so. Under the new pretrial system, courts determine release conditions and, in statutorily eligible cases, may order detention based on standards including specified safety risks or willful flight.
The third pulls the other way. The 2017 Safe Neighborhoods Reform Act lengthened prison terms for repeat gun offenders.

Each of these agencies runs its own hiring process, and most post openings directly. Start with the one that matches the job you want.
Professional Associations Worth Joining in Illinois
Most of these groups offer discounted student memberships. For about the price of a textbook, you get working professionals to ask questions of, scholarship lists, and job boards that never reach the public listings.
