- The exam has exactly three sections: Federal & State Law (23), Licensing & Practice Requirements (12), Security Practices (40).
- Security Practices is not one uniform block - it splits into Planning & Administration (10), Technology & Safety (12), and Security Operations (18).
- You have 90 minutes for 75 single-best-answer questions, and passing requires a scaled score of 70 or higher, not 70/75 correct.
- Security Operations is the single largest subarea on the entire exam at 18 questions - build your study plan around it.
Exam Overview: 75 Questions, 90 Minutes, Three Sections
The Illinois Private Security Contractor License Exam (IL-PSC) is administered by Continental Testing Services on behalf of the Illinois Department of Financial and Professional Regulation, Division of Professional Regulation, under profession 119. It is a standalone exam separate from the combined detective/security-contractor sitting, which instead uses 115 questions and a 120-minute limit with its own eligibility and fees. If you're only pursuing the security-contractor license, you'll sit for the 75-question, 90-minute version described in this guide.
Every question on the IL-PSC is single-best-answer multiple choice - there are no scenario simulations, drag-and-drop items, or written-response sections. That format matters for how you prepare: your goal is recognition and recall speed across three defined content areas, not essay-style reasoning.
Before diving into each domain, it helps to understand the full weighting picture at a glance:
| Domain | Question Count | Share of Exam |
|---|---|---|
| Domain 1: Federal & State Law | 23 | ~31% |
| Domain 2: Licensing & Practice Requirements | 12 | ~16% |
| Domain 3: Security Practices | 40 | ~53% |
Notice that Security Practices alone accounts for more than half the exam. That single fact should drive most of your study-time allocation, which we'll cover in detail below. For a broader look at what makes this exam challenging, our IL-PSC difficulty guide walks through common trouble spots by section.
Domain 1: Federal & State Law (23 Questions)
Federal & State Law is the second-largest domain, and it's where many candidates underestimate the exam. This isn't a memorization exercise on obscure statutes - it's a test of how well you understand the legal boundaries a licensed contractor and their employees operate within on a daily basis.
Federal & State Law
Candidates must understand the statutory and regulatory framework governing private security work in Illinois, including how state law interacts with federal authority in areas like detention, use of force, and reporting.
- Scope of authority for licensed contractors and their employees
- Legal limits on detention, search, and use of force
- Reporting obligations and interaction with law enforcement
- Liability exposure tied to statutory violations
Because this domain carries 23 of 75 questions, missing large portions of it puts real pressure on your overall score. Treat it as a co-equal priority with the licensing domain even though it's smaller than Security Practices - nearly a third of the exam sits here.
Domain 2: Licensing & Practice Requirements (12 Questions)
At 12 questions, Licensing & Practice Requirements is the smallest of the three sections, but it's also the most procedural - and procedural material is often the easiest to lock in with focused review.
Licensing & Practice Requirements
This domain covers the operational rules for how a licensed contractor and their agency must function, separate from the underlying legal statutes tested in Domain 1.
- Requirements for maintaining an active individual license
- Recordkeeping and documentation obligations for licensed contractors
- Standards for supervising employees and delegating responsibilities
- Practice boundaries that distinguish licensed contractor duties from unlicensed guard work
Key Takeaway
Because Domain 2 is only 12 questions, don't over-invest study hours here at the expense of Security Practices. Get comfortable with the material once, then move on.

Domain 3: Security Practices (40 Questions)
Security Practices is more than half the exam by question count, and it is not a single homogenous topic. Rather, it's built from three published subareas that each carry their own weight. Understanding this internal structure is the single most important thing you can do to organize your prep.
Security Practices Subareas Explained
Planning & Administration (10 Questions)
Covers the administrative backbone of a security operation - how contracts, staffing plans, post orders, and administrative controls are structured and maintained.
- Development and use of post orders and standard operating procedures
- Staffing and scheduling considerations for contract security work
- Administrative documentation practices
Technology & Safety (12 Questions)
Covers the tools and safety protocols contractors and their personnel rely on in the field, from basic equipment use to safety procedures during incidents.
- Appropriate use of security technology and equipment
- Safety protocols during routine and emergency situations
- Coordination between technology systems and physical security personnel
Security Operations (18 Questions)
The largest subarea on the entire exam - larger than either Domain 1 or Domain 2 individually. This covers the day-to-day realities of running and supervising a security operation.
- Patrol procedures and incident response
- Supervisory decision-making in the field
- Incident documentation and escalation protocols
- Coordination with clients and site-specific requirements
Because Security Operations alone represents 18 of 75 total questions - nearly a quarter of the entire exam - it deserves dedicated review sessions rather than being folded into general "security practices" study. If you're building your own practice questions, use these published counts (10, 12, 18) to keep your self-testing proportional to the real exam.
Why the Weighting Matters for Your Prep
A common mistake is spending equal time on all three domains because there are "three sections." The published counts tell a different story: Security Practices (40) is roughly 3.3 times larger than Licensing & Practice Requirements (12), and Federal & State Law (23) still outweighs Licensing by nearly double. Your time allocation should reflect that imbalance directly.
This is also why generic "one-size-fits-all" study advice falls short for this exam. For a walkthrough of how to structure a full prep plan around these specific weights, see our IL-PSC Study Guide.
Mapping Domains to a Study Schedule
If you're working from a multi-week timeline, sequence your study blocks by domain size and complexity rather than by the order they appear in the exam guide. Start with the largest, most operationally dense subarea - Security Operations - while your energy and focus are highest, then work down to smaller, more procedural material.
Security Operations & Technology and Safety
- Review patrol, incident response, and supervisory decision-making scenarios
- Study equipment use and field safety protocols
- Build practice questions weighted toward the 18-question Security Operations subarea
Federal & State Law
- Focus on scope of authority, use-of-force limits, and reporting obligations
- Drill statutory scenarios most likely to appear across 23 questions
Planning & Administration + Licensing & Practice Requirements
- Review post orders, staffing plans, and administrative documentation
- Study recordkeeping and supervisory practice standards
Full-Length Review
- Take timed practice sets matching the 75-question, 90-minute format
- Revisit weak areas identified across all three domains
You can run full-length timed practice sets modeled on the real 75-question structure at our IL-PSC practice test platform to see exactly where your domain-level weaknesses sit before test day.
Before You Register: CORE Approval and Fees
Domain content is only half the picture - you also need to clear administrative steps before you can even sit for the exam. Applicants must obtain IDFPR CORE approval and an authority-to-sit/examination approval ID before registering with Continental Testing Services. This step is separate from studying the domains themselves but frequently trips up candidates who assume they can register directly.
The exam fee is $298, and the separate individual license application fee is $500, with fingerprinting, insurance, preparation, and agency fees additional. For a full cost breakdown across every stage of the process, see our IL-PSC Certification Cost guide. And if you're tracking testing windows and deadlines, check our IL-PSC Exam Dates guide for current scheduling details.
Key Takeaway
Secure your CORE approval and authority-to-sit ID early - this administrative step has its own timeline separate from your domain study schedule.
Once you're eligible and registered, the most efficient use of remaining prep time is targeted practice testing that mirrors the real domain proportions. Run through full simulations at the main IL-PSC practice test site to confirm your readiness across Federal & State Law, Licensing & Practice Requirements, and Security Practices before locking in your test date.
Frequently Asked Questions
There are exactly three top-level domains: Federal & State Law (23 questions), Licensing & Practice Requirements (12 questions), and Security Practices (40 questions). Security Operations, Technology & Safety, and Planning & Administration are subareas within Security Practices, not separate domains.
Security Practices is the largest domain with 40 of 75 total questions. Within it, the Security Operations subarea alone accounts for 18 questions, making it the single largest content block on the exam.
No. The standalone Private Security Contractor exam has 75 questions and a 90-minute limit. The combined detective/security-contractor sitting is a different exam with 115 questions, 120 minutes, and its own separate eligibility, application, and fee requirements.
No. Study time should roughly reflect the published question counts - Security Practices deserves the most time at 40 questions, followed by Federal & State Law at 23, and Licensing & Practice Requirements at 12.
The published passing score is 70 or higher on the exam's scale, not a raw count of correct answers out of 75. See our passing score guide for a full explanation of how this is calculated.
