- Preassignment training is 8 hours total, with at least 4 hours in a formal, organized setting.
- Completion requires every answer correct, or every missed answer reviewed and initialed by both applicant and trainer.
- Original license and background-check fee is $101; annual renewal is $95, with a 1-year license term.
What This Cheat Sheet Covers
This page is a compressed reference for the Washington Security Guard License Exam (WA-SG) - the individual unarmed private security guard preassignment examination administered under Washington State Department of Licensing (DOL) rules. It is not a summary of the separate company-principal exam or the certified-trainer exam; those follow different rules and are outside the scope of this site.
Use this as a final review the night before your test date, or as a checklist while you work through the full WA-SG Study Guide 2026: How to Pass on Your First Attempt. If you want the long-form breakdown of any single fact below, the linked articles go deeper into that specific topic.
The Five Exam Domains at a Glance
WAC 308-18-300 expressly identifies five subjects as the source of exam questions. Every question on your test traces back to one of these five domains. For the full explanation of each, see the WA-SG Exam Domains 2026: Complete Guide to All 5 Content Areas.
Domain 1: Basic Principles
Foundational knowledge of the security guard role, professional conduct, and the boundaries of the job.
- Understand what distinguishes a licensed unarmed guard from law enforcement
Domain 2: Legal Powers and Limitations
What a guard can and cannot legally do on the job, including the limits of authority compared to sworn officers.
- Know where guard authority ends and where it requires deferring to police
Domain 3: Emergency Response
Correct actions during fires, medical incidents, and other emergencies on a job site.
- Prioritize life safety and correct notification procedures
Domain 4: Safety and Accident Prevention
Recognizing hazards and following procedures that reduce risk to the public, property, and the guard.
- Identify common hazard types and appropriate preventive steps
Domain 5: Report Writing
Producing clear, factual, and complete incident documentation.
- Distinguish objective observation from opinion in written reports
Key Takeaway
Study strictly against the preassignment rule (WAC 308-18-300) - don't substitute the separate postassignment syllabus, which covers different material for a different stage of licensing.
Fees, Licensing & Registration Mechanics
The money and paperwork side of WA-SG is straightforward once you know the numbers:
- Original license and background-check fee: $101
- Annual renewal fee: $95
- License term: 1 year
Beyond the fee itself, applicants must satisfy identification, fingerprint, application, and criminal-fitness requirements before DOL issues the license. Criminal-history review follows statutory job-related criteria - it is not an automatic disqualification for every prior conviction. For the complete cost breakdown, including how these fees interact with training and employer costs, see the WA-SG Certification Cost 2026: Complete Pricing Breakdown.
Eligibility Snapshot
Before you can sit for the exam, you need to meet basic eligibility conditions set by statute:
- At least 18 years old
- A U.S. citizen or resident noncitizen
- Employed, or holding an employment offer, from a licensed security company - or you hold the relevant company license yourself
- Cleared through identification, fingerprint, and application review
- Meets criminal-fitness standards based on job-related criteria rather than a blanket ban on any past conviction
There's one notable exception path: qualifying former full-time sworn peace officers who apply within 5 years of leaving law enforcement may receive a waiver of the preassignment training requirement. That waiver does not extend to the exam itself - they must still pass it. A full walkthrough of every eligibility rule lives in WA-SG Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Preassignment vs. Postassignment Training Hours
WA-SG candidates often confuse preassignment and postassignment training because both use the word "training," but the hour requirements and timing are different.
| Training Stage | Total Hours | Key Detail |
|---|---|---|
| Preassignment (before working) | 8 hours | At least 4 hours must be in an organized, formal setting; these hours are training time, not exam duration |
| Initial Postassignment | At least 8 hours | Deadline depends on license date: Jan-Jun licensees finish by June 30 of the following year; Jul-Dec licensees finish by Dec 31 of the following year |
| Annual Refresher (subsequent years) | At least 4 hours | Recurs every year the license is renewed |
Only the preassignment stage is tested by the exam covered on this site. Postassignment and refresher hours matter for keeping your license active, but they follow a separate syllabus and separate deadlines. Do not prep for the exam using postassignment material - it will not match the questions DOL draws from WAC 308-18-300.
Exam Format & the Completion Rule
The WA-SG exam is a multiple-choice test designed and supplied by DOL. A department-certified trainer oversees the session and confirms it was completed correctly. The completion standard is specific and worth memorizing exactly:
Key Takeaway
You "complete" the exam when every answer is correct, or when each incorrect answer has been reviewed for understanding and initialed by both you and the trainer. There is no separate published numeric passing score to memorize beyond this review-and-initial process - see WA-SG Passing Score 2026: Exactly What You Need to Pass for a deeper explanation of how this works in practice.
Because a trainer reviews any missed question with you on the spot, the process is less about a hard cutoff score and more about demonstrating you understand the material well enough to correct any gap immediately. That structure rewards genuinely learning the five domains rather than guessing and moving on. If you're trying to gauge overall difficulty going in, How Hard Is the WA-SG Exam? Complete Difficulty Guide 2026 breaks down what makes certain domains more challenging than others.
A One-Week Domain-by-Domain Review Plan
If your preassignment training and exam date are close together, a short, domain-anchored review works better than generic study advice. Map your review nights directly onto the five WAC 308-18-300 domains instead of studying "everything" at once.
Basic Principles & Legal Powers and Limitations
- Review guard role boundaries and where authority stops versus law enforcement
Emergency Response & Safety and Accident Prevention
- Walk through fire, medical, and hazard scenarios you'd realistically face on a post
Report Writing
- Practice writing short, factual incident summaries without inserting opinion
Mixed Review
- Cycle through practice questions across all five domains, flagging weak spots for a final pass
Scheduling this way keeps each domain isolated long enough to actually learn it, then forces integration at the end - which mirrors how the real exam mixes questions across all five subjects rather than grouping them by section.
Mistakes That Trip Up Otherwise Ready Applicants
- Studying the wrong syllabus: Preparing with postassignment training material instead of the preassignment content tested on exam day.
- Assuming a criminal record automatically disqualifies you: Washington applies job-related criteria, not a blanket ban - don't skip applying based on a false assumption.
- Missing the training-hour split: Forgetting that at least 4 of the 8 preassignment hours must happen in a formal, organized setting, not informally on the job.
- Confusing the temporary registration card with a full license: It expires in 60 days, only covers the issuing employer, and never authorizes firearms use.
- Not tracking postassignment deadlines after passing: The June 30 / December 31 deadlines depend on when you were initially licensed, and missing them affects renewal, separate from exam prep.

FAQ
No. This page and this site focus specifically on the individual unarmed private security guard preassignment examination. The company-principal and certified-trainer exams follow separate rules not covered here.
Five: Basic Principles, Legal Powers and Limitations, Emergency Response, Safety and Accident Prevention, and Report Writing, as identified in WAC 308-18-300.
Completion requires either every answer be correct, or each incorrect answer be reviewed for understanding and initialed by both you and the trainer. Missing a question doesn't automatically fail you - it triggers a review step.
Qualifying former full-time sworn peace officers who apply within 5 years may receive a waiver for preassignment training, but they must still pass the exam itself.
The license term is 1 year. Renewal costs $95 annually, separate from the $101 original license and background-check fee.
