California Guard Card Study Guide (2026): BSIS Power to Arrest Exam
To work as an unarmed security guard in California you need a BSIS Security Guard Registration(“guard card”). The gateway is the Power to Arrest and Appropriate Use of Force training and exam, which you must pass with a score of 100% (16 CCR § 628). This free guide covers the tested essentials — every fact is cited to the California Bureau of Security & Investigative Services — then drops you into free practice questions.

The tested essentials
The five areas the Power to Arrest & Appropriate Use of Force exam keeps coming back to.
Power to arrest: you act as a private person
A security guard is not a peace officer. Your authority to detain or arrest is the same private-person (“citizen’s”) arrest authority any member of the public has — you may arrest for a misdemeanor committed or attempted in your presence, or for a felony that was in fact committed, when you have reasonable cause. This is the core of the BSIS Power to Arrest module, and it is the single most heavily tested topic. Knowing the limits of that authority — and when to observe and report instead of act — is what the exam is checking.
Appropriate Use of Force (SB 652)
Effective under SB 652, the pre-assignment course now pairs Power to Arrest with a 5-hour Appropriate Use of Force module. Force must be objectively reasonable under the circumstances; guards are trained to de-escalate first, use only the force necessary, and stop once a threat ends. Prohibited and higher-risk techniques, the duty to render aid, and the duty to report every use-of-force incident are all fair game on the exam.
Observation, documentation & the incident report
Most of a guard’s real value is observing and reporting. A good incident report is factual, objective, and complete — it answers who, what, when, where, why, and how, records events in the order they happened, and avoids opinion or conclusion. The exam tests your ability to tell an observation (“the door was open”) from an assumption(“someone broke in”), because accurate notes are what stand up later in an investigation or in court.
Communication, ethics & public relations
A guard represents the client and the employer, so professional conduct, clear radio and verbal communication, and lawful, non-discriminatory treatment of the public are tested. This includes handling difficult people calmly, following post orders, protecting confidential information, and knowing the ethical limits of the role — you enforce rules and deter, you do not act as police.
Emergency response & WMD / terrorism awareness
Guards are trained to respond to fires, medical emergencies, evacuations, and hazards, and to recognize and report suspicious activity. Weapons of Mass Destruction & Terrorism Awareness is offered as a 4-hour elective course under the BSIS syllabus — it is not part of the mandatory 8-hour pre-assignment block, a point third-party guides frequently get wrong. The tested mindset is awareness and reporting through proper channels, not intervention.
Study every topic
Powers to Arrest
Authority to detain and arrest under California Penal Code §§834-851 — the statutes that define arrest, who may make one (peace officers under §836 vs. private persons under §837), reasonable cause, and what to do after.
Appropriate Use of Force
Reasonable-force standards for private security under California law, including the §835a peace-officer framework as reference, de-escalation duties, deadly vs. non-deadly force, and the SB 230 (2020) clarifications carried into the 2026 BSIS curriculum.
Liability & Legal Aspects
Civil and criminal liability exposure for security personnel: false imprisonment, battery, negligent hiring, vicarious liability of the employer (respondeat superior), trespass authority under §602, and mandatory-reporting duties.
Observation, Documentation & Report Writing
Patrol techniques, environmental awareness, note-taking, narrative report writing, witness questioning, and the documentation standards a security incident report must meet to be credible in court.
Communication, Public Relations & Ethics
Customer-service principles, conflict management and de-escalation through communication, body language, deception cues, written communication, and dealing with the press, government, and the public.
Emergency Procedures & Officer Safety
Fire, medical, and evacuation response; officer survival principles; basic first aid; equipment use; and coordination with police, fire, and medical responders.
Terrorism Awareness & WMD
Nature of terrorism, weapons of mass destruction (chemical, biological, radiological, nuclear, explosive), suspicious-activity indicators, and coordinating and sharing critical information with appropriate authorities.

California guard card exam — frequently asked questions
What is on the California guard card (BSIS) exam?
The core test is the BSIS Power to Arrest and Appropriate Use of Force examination, covering powers of arrest, reasonable use of force, observation and documentation, communication, ethics, and emergency response. You must pass it with a score of 100% (16 CCR § 628); retakes are permitted until you pass.
How many hours of training does a California guard card require?
40 hours total, completed within 6 months of starting work. This includes an 8-hour pre-assignment block — Power to Arrest (3 hours) plus Appropriate Use of Force (5 hours) — that must be finished before you are assigned to a post, followed by additional mandatory training. Source: BSIS Security Guard Training Regulation (bsis.ca.gov).
Do I need Weapons of Mass Destruction (WMD) training for a guard card?
WMD & Terrorism Awareness is a 4-hour elective course under the BSIS syllabus, not part of the mandatory 8-hour pre-assignment training. The required pre-assignment courses are Power to Arrest and Appropriate Use of Force.
What score do I need to pass the Power to Arrest exam?
100%. Under 16 CCR § 628 you must answer every question correctly to complete the Power to Arrest and Appropriate Use of Force training. Retakes are allowed, and most students pass within one or two attempts.
Does a guard card let me carry a gun on duty?
No. A guard card (BSIS Security Guard Registration) authorizes unarmed work only. To carry a firearm on duty you need a separate BSIS Firearms Permit, which requires additional firearms training, a separate exam, and periodic requalification.
How long is a California guard card valid?
Two years from the date of issue. To keep it current you must complete 8 hours of continuing education each year and renew the registration with BSIS before it expires.
Is a security guard a peace officer in California?
No. A security guard acts with private-person arrest authority, not peace-officer powers. Understanding that distinction — and when to observe and report rather than intervene — is central to the BSIS Power to Arrest exam.

Sample practice questions
A few real questions from this free bank, with full explanations. Use the practice tool above for the whole set.
- 1. Powers to Arrest
Under California Penal Code §835, an arrest is made by which of the following?
- a.Verbally informing the person they are under arrest
- b.An actual restraint of the person, or by submission to the custody of an officer
- c.Calling the police to the scene
- d.Identifying the suspect to a witness
Answer: b
Explanation: Penal Code §835 defines an arrest as being made by 'an actual restraint of the person, or by submission to the custody of an officer.' The person arrested may be subjected to such restraint as is reasonable for the arrest and detention. Verbal statements (a), summoning police (c), and witness identification (d) do not by themselves constitute an arrest under §835.
Source: Cal. Penal Code §835
- 2. Powers to Arrest
Which of the following best summarizes a key procedural difference between a peace-officer arrest and a private-person arrest?
- a.A peace officer may arrest for a felony on probable cause even if no felony actually occurred; a private person bears the risk that no felony was 'in fact committed'
- b.Peace officers must inform the arrestee of charges; private persons need not
- c.Private persons may use deadly force as a first option; peace officers may not
- d.Peace officers must obtain a warrant for every arrest; private persons need not
Answer: a
Explanation: The core procedural difference is the §837(3) 'in fact committed' requirement applied to private-person felony arrests, contrasted with the §836 probable-cause standard for peace officers. A peace officer acting reasonably is protected even if it later turns out no felony actually occurred; a private person is not. Both peace officers and private persons must give §841 notice (a is wrong). Deadly force authority is narrower, not broader, for private persons (c). Warrantless arrests are widely authorized for both categories under §§836 and 837 (d is wrong).

- 3. Use of Force
The U.S. Supreme Court in Graham v. Connor (1989) 490 U.S. 386 established that the constitutional reasonableness of force is judged from:
- a.The subjective intent of the officer at the time
- b.The perspective of a reasonable officer on the scene, without the benefit of 20/20 hindsight, considering the totality of the circumstances
- c.The view of the suspect being subjected to force
- d.An outcomes-based test focused on the injuries inflicted
Answer: b
Explanation: Graham v. Connor adopted the objective-reasonableness standard for Fourth Amendment seizure-by-force claims: courts judge force from the perspective of a reasonable officer on the scene, without 20/20 hindsight, considering all the facts and circumstances, including the severity of the crime, whether the suspect poses an immediate threat, and whether the suspect is actively resisting or attempting to flee. Subjective intent (a) is not the test; suspect perception (c) is not the standard; outcome-based liability (d) was rejected. Although Graham concerns peace officers, its reasonableness framework informs private-security civil standards.

- 4. Use of Force
When confronted by multiple non-compliant subjects, the guard's force decision should consider:
- a.Always escalate to the highest force option immediately
- b.Force is unlawful when multiple subjects are present
- c.Force is permitted only after every subject has thrown a punch
- d.The totality of circumstances — number of subjects, distance, weapons, environment, available escape routes, and feasibility of de-escalation — calibrating force to actual threat and continuing to consider lower-force alternatives
Answer: d
Explanation: Reasonableness is necessarily totality-driven. Numbers, proximity, weapons, terrain, and exit options bear on threat assessment but do not relieve the guard of the duty to consider de-escalation and proportionality. Reflexive maximum force (a) is unlawful and tactically poor; categorical force prohibitions (b) ignore the right of self-defense; waiting for an attack from each subject (c) is dangerous and not a legal requirement when an imminent threat is reasonably perceived. Tactical retreat is often the best option.

- 5. Liability & Legal
A guard privately reports a suspected shoplifter to the store manager and to responding police. The shopper turns out to be innocent and sues for slander. What defense most likely applies?
- a.Qualified ('common interest') privilege under Civil Code §47(c) — the communication was made without malice between parties with a common interest in loss prevention and law enforcement
- b.Absolute legislative privilege
- c.Statute of frauds
- d.Workers' compensation exclusivity
Answer: a
Explanation: Civil Code §47(c) provides a qualified privilege for communications made without malice between parties sharing a common interest. A guard's private report to a store manager (employer common interest) and to police (law enforcement common interest) typically falls within §47(c). The privilege is defeated by malice — knowing falsity or reckless disregard for truth. Public, loud accusations to uninvolved bystanders exceed the privilege's scope. Absolute legislative privilege (b) protects statements in official proceedings, not field reports. Statute of frauds (c) and workers' comp exclusivity (d) are unrelated. Truth is also a complete defense to defamation, separate from privilege.

- 6. Observation & Reports
A guard photographs an incident scene for documentation. California's constitutional privacy right and Civil Code §1708.8 mean the guard should:
- a.Photograph anyone, anywhere, at any time without limits
- b.Never photograph anything during a security incident
- c.Photograph the scene, evidence, and conduct relevant to the incident with reasonable judgment — avoiding gratuitous focus on private areas (restrooms, dressing rooms), bystanders unconnected to the incident, and any constructive intrusion into protected private activity
- d.Photograph only after obtaining written consent from every person depicted
Answer: c
Explanation: Photography for legitimate incident documentation is a standard, defensible practice — incident scenes, evidence, injuries (where consented or in plain view), and observable conduct. California's constitutional privacy right (Cal. Const. Art I §1) and statutes like Civil Code §1708.8 caution against gratuitous photography of bystanders, focused capture of private areas like restrooms or dressing rooms (which can be actionable under PC §647(j) and §647(i)), and intrusive use of telephoto or enhancing devices to capture private activity. Reasonable judgment, employer policy, and respect for privacy norms govern lawful incident-scene photography.

- 7. Communication & PR
A well-written security incident report should be characterized primarily by:
- a.Clarity, brevity, and factual accuracy — written so a stranger reading later understands what happened
- b.Vivid adjectives and emotional language to convey the seriousness of the incident
- c.Legal conclusions about whether the suspect committed a crime
- d.The author's personal opinions about the parties involved
Answer: a
Explanation: BSIS report-writing standards emphasize clarity, brevity, and accuracy. Reports must convey who, what, when, where, why (if known), and how, using neutral observable facts rather than conclusions or opinions. Emotional language (b) undermines credibility in court; legal conclusions (c) are reserved for prosecutors, judges, and juries; opinions (d) expose the writer and the employer to defamation claims. The standard test: a reader who was not present should understand the incident from the report alone.

- 8. Emergency & Safety
An employee answering a phone receives a bomb threat. The FBI/DHS-endorsed protocol calls for the call-taker to:
- a.Hang up immediately and ignore the call as a prank
- b.Stay on the line, record the caller's exact words, note voice characteristics and background sounds, signal a coworker to call 911, and after the call, complete the FBI bomb-threat checklist
- c.Demand the caller's name and threaten them with arrest
- d.Page the building over the PA system to announce 'bomb threat'
Answer: b
Explanation: FBI/DHS bomb-threat protocol calls for keeping the caller on the line as long as possible, recording exact words verbatim, noting voice characteristics (accent, age, gender, demeanor), background sounds (traffic, machinery, music, voices), and any specific details about the device or motive. A coworker silently signals 911. The completed Bomb Threat Checklist gives investigators critical leads. Hanging up (a) destroys intelligence value; threatening the caller (c) escalates and ends the call; public PA announcements (d) cause panic and may trigger an actual detonation if a device is present.
