Illinois Security Guard
Practice Test

A. Illinois Department of Financial and Professional Regulation (IDFPR) ✓

B. Illinois State Police

C. Illinois Department of Labor

D. Illinois Emergency Management Agency

Correct — A. The Illinois Department of Financial and Professional Regulation (IDFPR) oversees the licensing of private security contractors and security guards under the Private Detective, Private Alarm, Private Security, Fingerprint Vendor, and Locksmith Act of 2004.

A. Proportional to the threat being faced and necessary under the circumstances ✓

B. Any force the guard's supervisor has pre-approved in writing

C. The maximum force available to stop any illegal activity

D. Force that results in no injury to the subject

Correct — A. Reasonable force is determined objectively: would a reasonable person in the same situation use the same level of force? It must be proportional to the threat and no more than necessary to address the situation. Excessive force exposes the guard to criminal and civil liability.

A. A commission issued by the local police department

B. A federal security regulation

C. The property owner's consent and authorization ✓

D. An Illinois State Police permit

Correct — C. Security guards derive their authority on private property from the property owner or the employer who holds a contract with the property owner. This is a delegation of the owner's rights, not a governmental power.

A. Lethal force

B. Physical control techniques

C. Officer presence and verbal commands ✓

D. Chemical agents

Correct — C. The force continuum starts with the lowest level of force: the mere presence of the officer/guard and verbal communication. Security personnel should always attempt to resolve situations through presence and verbal de-escalation before escalating to physical measures.

A. Guards must physically intervene in all criminal acts they witness

B. Guards should document and report incidents without becoming involved in confrontations ✓

C. Guards have the same arrest powers as police officers

D. Guards are required to chase suspects off the property

Correct — B. The observe-and-report doctrine means security guards watch for suspicious activity, document incidents accurately, and notify law enforcement rather than taking direct enforcement action. This protects both the guard and their employer from liability.

A. Immediately apply a restraint hold to control the situation

B. Draw and display any authorized defensive tool

C. Retreat from the building and wait for police

D. Use calm verbal de-escalation techniques and maintain a safe distance ✓

Correct — D. Verbal threats without physical action generally do not justify physical force. De-escalation through calm tone, empathetic listening, and maintaining a safe distance allows the guard to manage the situation at the lowest force level while assessing whether the threat escalates.

A. A written warrant signed by a judge

B. Approval from IDFPR

C. Permission from a sworn police officer on scene

D. Reasonable grounds to believe the person committed an offense in the guard's presence ✓

Correct — D. Illinois follows the common-law citizen's arrest principle: a private person may detain someone when an offense has been committed in their presence and they have reasonable grounds to believe that person committed it. A warrant is not required.

A. Attempt to disarm the subject using bare-hands technique

B. Increase distance, call for help, and wait for law enforcement ✓

C. Block the knife with a forearm and tackle the subject

D. Pick up a nearby object and charge at the subject

Correct — B. When facing a deadly weapon, an unarmed security guard should create distance, take cover, and immediately contact law enforcement. Attempting to physically disarm a knife-wielding subject greatly increases the risk of serious injury or death to the guard.
