- FL-SO-D is Florida's Class "D" Security Officer License, overseen by FDACS Division of Licensing.
- The assessment has 170 questions total; 128 correct answers are needed to pass.
- Domains 1, 5, 13, and 17 carry the heaviest question weight - 26, 17, 19, and 17 items respectively.
- Testing is embedded in the 40-hour approved course, with at least two aggregate hours of testing time.
What Is FL-SO-D, Exactly?
FL-SO-D refers to Florida's Class "D" Security Officer License, a credential regulated by the Florida Department of Agriculture and Consumer Services (FDACS), Division of Licensing. It is the entry-level license required for most unarmed security officer positions in the state - the guard standing at a lobby desk, patrolling a warehouse, or checking credentials at an access point is very likely working under this license.
Unlike many professional certifications, there is no separately booked statewide exam vendor. Instead, the assessment is delivered by a licensed Class "DS" school or training facility as part of the state-approved 40-hour course. If you're comparing this to other testing programs, that structural difference matters - you can't just "sign up for the exam." You enroll in an approved course, and the assessment happens throughout or at the end of that instruction.
How the FL-SO-D Assessment Actually Works
The Class D curriculum requires 40 instructional hours, with a minimum of two aggregate hours dedicated to testing. That two-hour figure is a floor, not a ceiling - it's the minimum testing duration built into the course, not a hard cutoff you must beat like a timed exam.
Approved assessments contain 170 questions covering all subject areas from the training curriculum. To pass, a candidate needs 128 correct answers. Question format is also regulated: no more than 50% of the questions within any single subject area may be true/false, which means you'll also encounter multiple-choice and scenario-based items that test applied judgment, not just recall.
Key Takeaway
Because the test is woven into your approved course rather than scheduled separately, your best preparation window is during the course itself - reinforce material the same week it's taught rather than waiting until the end.

The 18 Domains and Their Question Weights
The subject areas assessed on the FL-SO-D exam come directly from the Security Officer Training Curriculum Guide (P-01878, revision 11/2018), incorporated into Rule 5N-1.140 as Reference 10454. There are 18 domains, and - critically - the number of questions assigned to each domain does not track proportionally with classroom hours. Some domains get far more test weight than their instructional time might suggest, so sizing your practice around question allocations, not hours, is the smarter strategy.
| Domain | Title | Questions |
|---|---|---|
| 1 | Legal Aspects of Private Security | 26 |
| 2 | Role of Private Security Officers | 9 |
| 3 | Security Officer Conduct | 13 |
| 4 | Principles of Communications | 9 |
| 5 | Observation and Incident Reporting | 17 |
| 6 | Principles of Access Control | 4 |
| 7 | Patrols | 4 |
| 8 | Principles of Safeguarding Information | 4 |
| 9 | Physical Security | 4 |
| 10 | Interviewing Techniques | 4 |
| 11 | Emergency Preparedness | 6 |
| 12 | Safety Awareness | 11 |
| 13 | Medical Emergencies | 19 |
| 14 | Terrorism | 11 |
| 15 | Event Security and Special Assignments | 4 |
| 16 | Communications Systems | 4 |
| 17 | Special Issues | 17 |
| 18 | Introduction to Weapons | 4 |
Domain 1: Legal Aspects of Private Security
With 26 questions - the single largest allocation - this domain covers the legal boundaries of a security officer's authority, arrest powers, use-of-force limitations, and liability. Candidates who underestimate this domain often underperform on the overall exam.
- Expect scenario questions testing what an officer legally can and cannot do
Domain 13: Medical Emergencies
At 19 questions, this is the second-heaviest domain. It covers recognizing and responding to medical incidents on post, a practical skill area that shows up disproportionately on the assessment relative to its classroom hours.
- Review response sequencing and when to escalate to emergency services

Who Hires Class D Officers
A Class D license is the baseline credential for unarmed security roles across Florida: retail and commercial property patrol, corporate and office building security, hospitality and event venues, healthcare facility access control, and contract security firms that staff guard posts for a wide range of clients. Because the license does not authorize firearm carry, employers hiring for those roles pair Class D with additional licensing when armed duties are part of the job.
If you're deciding whether pursuing this license is worth the time and course cost relative to the roles it opens up, the Is the FL-SO-D Certification Worth It? Complete ROI Analysis 2026 article and the FL-SO-D Jobs overview both go into more detail on career paths.
Eligibility and Application Basics
Applicants must be at least 18 years old and meet FDACS's status and suitability requirements - this includes background screening tied to the state's licensing statute. Some applicants qualify for training exemptions based on prior experience or credentials, which can shorten the path to the course itself.
Instruction and testing can also be completed through compliant live-online delivery, provided the school maintains required instructor presence, identity verification, attendance tracking, and platform safeguards. Self-paced practice questions are a useful supplement, but they do not substitute for the approved 40-hour course - the license application requires completion of that formal training.
A full eligibility checklist, including how exemptions work and what documentation FDACS expects, is covered in FL-SO-D Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Fees, Certificates, and Renewal
Successful students receive a school training certificate confirming course completion. For training finished on or after July 19, 2023, that completion is verified through FDACS's certificate verification system as part of the license application, replacing older paper-based verification steps.
Once issued, the Class D license is valid for two years. The renewal schedule lists a $45 renewal fee plus a $16.75 fingerprint retention fee. Because these are recurring costs tied to keeping the license active, it's worth budgeting for them alongside the initial course tuition.
Class D vs. Armed Duties
One of the most common points of confusion: Class D alone does not authorize a security officer to carry a firearm while performing security duties. Officers who need to be armed must hold the appropriate additional license on top of Class D. If a job posting requires firearm carry, Class D is a necessary foundation but not sufficient by itself.
Building a Domain-Weighted Study Plan
Generic study techniques - flashcards, timed review blocks, spaced repetition - work fine as tools, but they only pay off when pointed at the right material. For FL-SO-D, that means allocating review time in proportion to question count, not classroom hours. Domains 1, 5, 13, and 17 together account for nearly half of all 170 questions, so they deserve outsized attention even though several smaller domains (6, 7, 8, 9, 10, 15, 16, 18) are each capped at just 4 questions.
Foundational Legal & Conduct Domains
- Deep-dive Domain 1 (Legal Aspects of Private Security) - largest single weight at 26 questions
- Layer in Domain 3 (Security Officer Conduct) at 13 questions
Reporting, Communication, and Medical Response
- Domain 5 (Observation and Incident Reporting) - 17 questions
- Domain 13 (Medical Emergencies) - 19 questions
- Domain 4 (Principles of Communications) - 9 questions
Special Issues, Safety, and Terrorism
- Domain 17 (Special Issues) - 17 questions
- Domain 12 (Safety Awareness) and Domain 14 (Terrorism) - 11 questions each
Lower-Weight Domains and Mixed Review
- Batch-review the 4-question domains (Access Control, Patrols, Safeguarding Information, Physical Security, Interviewing Techniques, Event Security, Communications Systems, Introduction to Weapons)
- Run full-length practice sets mirroring the true/false-limited format
If you'd rather follow a ready-made week-by-week plan instead of building your own, the FL-SO-D Study Guide 2026: How to Pass on Your First Attempt lays one out in full. And if you're still gauging how challenging the material is before committing to a course, How Hard Is the FL-SO-D Exam? Complete Difficulty Guide 2026 walks through the difficulty factors in more depth.
Whatever plan you use, the goal is the same: practicing with domain-weighted question sets on the main practice test platform is more efficient than reviewing raw course notes cover to cover, since it mirrors how the real 170-question assessment is actually distributed.
