Step 1: Meet the Basic Requirements

  • Be a citizen or legal resident of the U.S.
  • Be at least 21 years old
  • Earn a high school diploma or GED
  • Have no criminal background
  • Not have any mental illness or medical condition that may impact your ability to do your work

Step 2: Acquire a PERC License

Before you can start working as a private investigator in Illinois, you must acquire a PERC license, also known as a permanent employee registration card.

You can get this license from the Illinois Department of Financial and Professional Regulation (IDFPR).

This license confirms that you are qualified to work as a private investigator in Illinois.

To apply for a PERC license, you must first submit a copy of your fingerprints, submit a copy of your social security card, complete the application, and pay a $55 application fee.

Step 3: Earn the Necessary Experience

In Illinois, those aspiring to become private investigators should gain at least three years of investigative experience.

This equals 2,000 hours each year.

The experience that you gain should be under the supervision of a licensed private investigator or through a law enforcement agency.

When you apply for a license, the experience you list must be within the past five years.

You also have the option to gain two years of experience and earn a bachelor’s degree in law enforcement or another related field.

Step 4: Gain PI Training

Once you are employed by a law enforcement agency or by a private investigative agency, you must complete at least 20 hours of the required training within your first 30 days of employment.

You’ll learn about courtroom preparation, Illinois laws and statutes, surveillance techniques, investigation ethics, and more in the 20-hour training course.

Step 5: Complete Class A PI Application

Once you’ve completed the 20-hour training course and have gained enough experience, you can complete an application to become a licensed PI in Illinois.

To do this, you should fill out an application and submit it to IDFPR.

You will be told to include all supporting documents along with your application.

Step 6: Pass a Criminal Background Check

After you’ve successfully applied for IDFPR, you will undergo a background check.

Your fingerprints will also be processed to make sure that your background is clean and free of any felonies or misdemeanors.

You may have to pay a fingerprint processing fee at the time you submit your application.

Step 7: Take the Licensing Exam

Once your licensing application has been approved, you must then take a written Class A licensing exam that is administered by the IDFPR.

The fee for this exam is $298, and it is only administered twice a year.

You’ll answer 75 questions in the exam, all of which should take about 90 minutes to complete.

The exam will prove your knowledge of the laws and regulations in Illinois concerning PI work.

Once you have completed the exam, you must submit proof of liability insurance to IDFPR of at least $1,000,000.

Step 8: Maintain your License

Once you receive your license, you must maintain it by completing continuing education courses.

This ensures that you remain up to date with any changes in the laws within your industry.

Continuing education courses are beneficial because they can lead to better career opportunities for you in the future and even help your professional development.
