Though Illinois has long been a beacon for private investigators looking to tackle big-city cases involving industrial espionage or political corruption, there are just as many opportunities for PIs in Chicago, Aurora, Rockford, and Joliet looking to get into the field to do the bread and butter investigations work PIs are known for – things like catching a cheating spouse in the act when their partner suspects marital infidelity, checking up on parents in child custody disputes, and looking into insurance fraud.
There’s been more than one person busted for disability insurance fraud after claiming a back injury and then bragging to their friends on Facebook about their weekend getaway, complete with zip lining and parasailing pictures.

Just as social media ushered in a whole new way to catch people in the act of doing things they shouldn’t be, the #MeToo movement has helped create an environment where people are paying attention and sexual harassment is no longer something that’s being ignored.
This has prompted many companies, universities, and government agencies to get to the bottom of harassment claims instead of brushing them off. PIs are called in to handle many of these cases using their patented blend of discretion and rock-solid investigative skills.
According to the Illinois Department of Employment Security, 880 PIs were working in Illinois in 2019 – that’s a pretty uncrowded market for a state this size. The relatively small number of PIs in Illinois is likely a result of the state’s stringent requirements for licensure, which has helped weed out anybody looking to skirt the law and earn a quick buck in the field. Instead, private investigators in Chicago and throughout Illinois enjoy a solid reputation for being reliable and trustworthy, and often have more cases than they can handle.
The Department of Financial and Professional Regulation is responsible for licensing private investigators in Illinois. Be prepared to come to the table with at least three years of experience/post-secondary education and a clean criminal record if you want to earn licensure here. Here’s all that you need to know about how to become a private investigator in Illinois:
Step 1. Determining Your Application Route in Illinois
You can apply for a license for private investigator jobs in Illinois based on either set of qualifications:
- Education and experience
Once you meet the training requirements, pass an exam, complete the rest of the application materials, and are successfully licensed you will have the following options:
- Work for another private investigator
- Go into business as a sole-proprietor
- Enter into a PI partnership
- Form a PI corporation
- Form a PI limited liability company (LLC)
Step 2. Qualifying for the PI Exam and License in Illinois
Based on Experience
If you are applying for a PI license exam based on your experience you will need to submit proof of working for three of the past five years in any one of the following:
- As a full-time private detective
- As a full-time investigator in any one of the following:
- Federal, state, county, or city law enforcement department
- State’s Attorney’s or Public Defender’s office
- Military police also must submit DD 214
Based on Education and Experience
You can also qualify for a PI license by meeting certain private investigator school requirements in Illinois. If you have an associate’s degree in law enforcement or a related field this may substitute for one year of qualified experience as mentioned above. Having a bachelor’s degree in a field related to law enforcement will substitute for two years of qualified experience as mentioned above.

Within six months of employment, you will need to complete an additional eight hours of training in a pertinent subject. To prove you have completed the necessary training you will need to submit your basic training certification.

- 20 hours of classroom instruction including:
- Law and the use of force
- Law, private police, and law enforcement reporting
- Fire prevention
- Range instruction in:
- Combat shooting
- Double-action shooting
If you have already completed a similar course you may be eligible to submit a waiver of firearms training.
Step 4. Submitting a Complete Application for Licensure in Illinois
Along with your complete application for licensure based either on experience or experience and education, you will also need to submit the following to the Illinois Department of Financial and Professional Regulation, the agency responsible for issuing your license:
- Criminal background check
- Proof of a $1 million liability insurance policy
- $291 examination fee
- Once you are eligible to be licensed you will be notified of the licensure fee
- Fingerprints and authorization for a background check with the Illinois State Police
If you are choosing to carry a firearm you will need to submit either your firearm training certification or a waiver of firearm training if you have already completed comparable training
