A. Illinois Department of Revenue

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

C. Illinois State Police

D. Illinois Department of Labor

Correct — B.

Applicants must meet IDFPR requirements before working as a security officer.

A. The officer's personal judgment regardless of circumstances

B. The instructions of the client company

C. Whether the force used was reasonable and proportional to the threat ✓

D. Whether the suspect was eventually convicted

Correct — C. Force is justified only when it is reasonable and proportional to the threat faced. Courts evaluate use of force by asking what a reasonable person in the same circumstances would have done, not based on outcomes like conviction.

A. A Chicago Police Department officer

B. An Illinois State Trooper

C. A private citizen ✓

D. A federal law enforcement agent

Correct — C. A private security officer does not have police powers. On private property, their legal authority is generally that of a private citizen, meaning they may only act within the bounds of what any ordinary citizen may do under Illinois law.

A. Officer presence ✓

B. Lethal force

C. Physical restraint

D. Chemical agents

Correct — A. The force continuum begins with officer presence—the mere visible presence of a uniformed security officer can deter threats without any physical intervention. Officers should always start at the lowest effective level of the continuum.

A. A felony has been committed in their presence ✓

B. They personally suspect someone of a misdemeanor

C. A police officer verbally requests their assistance

D. The employer gives written authorization

Correct — A. Illinois law allows a private person to arrest another when a felony has been committed in their presence or when they have reasonable grounds to believe a felony has been committed. This authority is more limited than that of a sworn police officer.

A. Immediately use physical restraint to prevent escalation

B. Draw a weapon to show authority

C. Leave the area and ignore the subject

D. Use calm verbal commands and de-escalation techniques ✓

Correct — D. When a subject is only verbally aggressive, the appropriate response is verbal de-escalation—using a calm voice, clear instructions, and active listening to reduce tension. Physical force is not appropriate at this level of the continuum.

A. Detain all suspicious persons until police arrive

B. Issue citations for trespassing violations

C. Conduct undercover investigations on site

D. Monitor the premises and report incidents to management or law enforcement ✓

Correct — D. An observe-and-report officer's core duty is to watch for and document incidents, then notify appropriate authorities or management. They are not authorized to conduct arrests, investigations, or issue citations.

A. Any force used by a security officer

B. Force that goes beyond what is reasonably necessary to control a situation ✓

C. Force that results in a minor injury to the suspect

D. Force used without the officer's supervisor present

Correct — B. Excessive force is force that exceeds what a reasonable person would consider necessary given the circumstances. Using more force than the situation requires exposes security officers to civil and criminal liability.
