- Schroeder Measurement Technologies develops and administers the exam under 201 KAR 41:030.
- Passing means scoring at least 260 on a 150-300 scale - not a percentage-correct target.
- The exam fee is $156, separate from the $400 total application and licensure charges.
Where the Six Domains Come From
Unlike many licensing exams built from a proprietary "job task analysis" that a testing company keeps confidential, the KY-PI content outline is written directly into Kentucky law. The six domains reproduced in this guide come verbatim from KRS 329A.025(2)(c), which the Kentucky Board of Licensure for Private Investigators incorporated into the examination regulation, 201 KAR 41:030. That regulation also names Schroeder Measurement Technologies Inc. as the board-approved examination service responsible for building and administering the Kentucky Private Investigator Examination.
Because the domains are statutory, they don't get quietly rewritten every testing cycle. What changes is the underlying case law and statute language behind each domain, which is why the board's official study guide - 14 chapters, last revised April 8, 2009 - needs to be read alongside current Kentucky statutes and regulations rather than treated as a standalone answer key. If you haven't already worked through the baseline material, the KY-PI Study Guide 2026: How to Pass on Your First Attempt walks through how to reconcile the older guide with current law before you touch a single practice question.
Domain 1: Federal and State Constitutional Principles
Federal and State Constitutional Principles
This domain tests whether a candidate understands the constitutional guardrails that shape everything a private investigator does in the field - surveillance, interviews, records access, and evidence handling. Kentucky investigators operate under both the U.S. Constitution and the Kentucky Constitution, and questions in this area check whether you can distinguish protections that apply to government actors versus private individuals.
- Fourth Amendment concepts as they intersect with private (non-state-actor) investigative work
- Due process and equal protection principles relevant to licensing and enforcement actions
- How Kentucky constitutional provisions can diverge from federal baseline protections
Domain 2: Invasion of Privacy Case Law
Court Decisions on Invasion of Privacy and Related Liability
This domain is entirely case-law driven, which makes it one of the trickier areas to memorize by rote. It covers court decisions addressing activities that could expose an investigator - or the client who hired them - to civil liability for invasion of privacy or other tortious conduct.
- Recognized categories of invasion-of-privacy claims in surveillance and investigative contexts
- Where courts have drawn the line between lawful observation and actionable intrusion
- How liability exposure connects to the licensing requirement for combined single-limit liability insurance of at least $250,000, with the statutory exception for investigators supervised exclusively by Kentucky-licensed attorneys
Domain 3: Eavesdropping, Assault, Search and Seizure, Computer Access
Eavesdropping and Related Offenses, Assault, Search and Seizure, Unlawful Computer Access
This is the densest domain on the exam because it bundles four distinct legal categories into a single content area. Expect questions covering eavesdropping and wiretapping-related offenses, assault and related offense definitions, search and seizure law as applied to evidence gathering, and Kentucky's laws governing unlawful access to a computer.
- Distinguishing lawful recording scenarios from criminal eavesdropping exposure
- Assault-related offense elements that matter when investigators conduct in-person contact work
- Search and seizure principles applied to documents, devices, and physical evidence
- Unlawful computer access statutes relevant to background research and digital investigations
Key Takeaway
Because Domain 3 combines four legal categories, allocate more review sessions to it than any single-topic domain - it carries the broadest statutory footprint on the exam.
Domain 4: Weapons Use and Concealed Weapons Laws
General Weapons Use and Concealed Weapons Laws
This domain covers the legal framework around weapons use generally and concealed carry specifically, as it applies to Kentucky-licensed investigators in the course of their work. Candidates should be comfortable with the statutory boundaries around possession and use rather than firearms training itself - this is a legal-knowledge domain, not a marksmanship requirement.
- General legal principles governing weapons use during investigative activity
- Concealed weapons law as it applies to licensed private investigators in Kentucky
- How weapons-related conduct intersects with the liability and licensing obligations covered elsewhere in the exam
Domain 5: Additional State Criminal Laws and Procedures
Additional State Criminal Laws and Related Procedures
This domain is intentionally broad. It captures Kentucky criminal statutes and procedural rules that don't fit neatly into the eavesdropping, assault, search-and-seizure, or computer-access bucket in Domain 3, but that still bear directly on how an investigator can lawfully conduct business.
- Criminal statutes relevant to common investigative activities not addressed in Domain 3
- Procedural rules that affect how evidence or information gathered by an investigator can be used
- General familiarity with the structure of Kentucky's criminal code as it touches investigative work
Domain 6: Additional Board-Determined Subject Areas
Additional Subject Areas as Determined by the Board
Domain 6 exists so the Kentucky Board of Licensure for Private Investigators can incorporate emerging or supplemental content without amending the statute every time. It's the hardest domain to "study for" in a traditional sense because its scope is set at the board's discretion rather than fixed by a static list.
- Treat the board's current study guide and any board communications as the primary source for this domain
- Re-check the board's site periodically in the months before your test date, since this domain can shift
- Don't assume older prep material fully covers this domain - it is the most likely to be updated over time
For a broader sense of how these six domains combine to affect overall exam difficulty, see How Hard Is the KY-PI Exam? Complete Difficulty Guide 2026, and for a domain-by-domain quick reference you can keep open during final review, check the KY-PI Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Exam Format, Delivery, and Scoring
The Kentucky Private Investigator Examination is computer-administered. You'll sit for it either at an approved contractor testing center or through a contractor- and board-approved electronic testing method. There is no indication in board materials of an oral or practical component - this is a written, computer-delivered knowledge test drawn from the six domains above.
Scoring uses a scaled system running from 150 to 300, and you need at least a 260 to pass. That scaled score is not a raw percentage-correct figure, so you cannot simply count how many of, say, 100 questions you answered correctly and assume that number equals your score. For a full breakdown of how the scaling works and what it means for your preparation, see KY-PI Passing Score 2026: Exactly What You Need to Pass.
Registration and Fee Mechanics Tied to Content
The domains don't exist in a vacuum - they're wrapped inside a specific registration and deadline structure that affects how you should schedule your study time.
- The examination fee is $156, paid to the examination service, separate from the $400 total individual application and licensure charges.
- Of that $400, $100 is due within 30 days of initial application, and the remaining $300 is due when you submit proof of a passing score.
- Once you receive your eligibility notice, you must sit for the exam within 60 days and submit a passing score within six months of that notice.
- A second attempt is allowed within that same six-month window; a second failure triggers a 12-month waiting period before you can sit again.
These deadlines mean your domain review has to be front-loaded, not stretched indefinitely. If you're still assembling your application timeline, KY-PI Requirements 2026: Eligibility, Prerequisites & How to Qualify covers the eligibility criteria - age 21 minimum, U.S. citizenship or resident alien status, high-school education or equivalent, and character/background requirements - that determine when your 60-day and six-month clocks even start. For the full fee picture including renewal costs, see KY-PI Certification Cost 2026: Complete Pricing Breakdown, and for the exact windows and deadlines laid out on a calendar, review KY-PI Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

Mapping a Study Schedule to the Six Domains
Rather than studying generically, sequence your review so the densest, hardest-to-memorize domains get the most calendar time before your 60-day testing window opens.
Domains 1 & 2 - Constitutional and Case-Law Foundation
- Read the constitutional principles chapters in the board's study guide, cross-checking against current case law
- Build a running list of invasion-of-privacy decisions and the fact patterns that triggered liability
Domain 3 - Eavesdropping, Assault, Search/Seizure, Computer Access
- Split this domain into its four sub-areas and study each separately before combining them
- Drill scenario-based questions since this domain blends criminal law with practical field situations
Domains 4 & 5 - Weapons Law and Additional Criminal Statutes
- Focus on concealed weapons statutory boundaries rather than firearms mechanics
- Review any Kentucky criminal statutes not already covered under Domain 3
Domain 6 & Full Review
- Check the board's current published materials for any board-determined additions
- Run full-length practice sessions covering all six domains together
If you want a structured walkthrough of this kind of sequencing with more detail on pacing and review cycles, the KY-PI Study Guide 2026: How to Pass on Your First Attempt expands on how to fit this timeline inside your 60-day and six-month deadlines.
Who Hires Around This Content
The six domains aren't abstract legal trivia - they reflect the actual liability and legal-boundary questions that come up constantly in Kentucky PI work: insurance defense firms needing surveillance conducted without privacy-tort exposure, attorneys needing background and skip-trace work performed within search-and-seizure limits, and corporate clients needing due-diligence investigations that don't cross into unlawful computer access. Understanding how the domains connect to real engagements is useful context whether you're comparing career paths or negotiating pay. For that broader context, see KY-PI Salary Guide 2026: Complete Earnings Analysis, KY-PI Jobs, and Is the KY-PI Certification Worth It? Complete ROI Analysis 2026 for a fuller return-on-investment picture.
Once you're ready to test your recall against realistic, domain-tagged questions, you can start practicing on the main practice test platform, which organizes drills around these same six statutory domains rather than generic PI trivia. Working through timed sets on the practice site before your scheduled test date is one of the more direct ways to see where your Domain 3 or Domain 5 knowledge still has gaps.
Frequently Asked Questions
The domains themselves are set by KRS 329A.025(2)(c), so they don't change casually. What can shift is the case law, statute language, and board-determined content under Domain 6, which is why current statutes should always be checked against the 2009-revised study guide.
Many candidates start with Domain 1 and Domain 2 because they establish the constitutional and case-law foundation the other domains build on, then move into the denser Domain 3 material on eavesdropping, assault, search and seizure, and computer access.
The board's published sources list the six domains from KRS 329A.025(2)(c) without publishing a specific per-domain question-weight breakdown, so candidates should prepare all six thoroughly rather than assuming any one domain is minor.
The exam is computer-administered at an approved contractor testing center or via an approved electronic testing method, consistent with a written knowledge-based format built from the six statutory domains.
A second attempt is allowed within the original six-month window after your eligibility notice. If that second attempt also fails, you face a 12-month restriction before you can sit for the exam again.
