What "Passing" Actually Means for the ND-PI Exam
Every candidate researching the North Dakota Private Investigator License Exam wants one number: the minimum score needed to pass. The North Dakota Private Investigation and Security Board (NDPISB) does not publish a single universal cutoff percentage in its public materials, and it would be a disservice to invent one just to give you a tidy answer. What the Board does make clear is the structure around passing: you must clear the exam within the 12 months immediately preceding your license application, and the consequences of not clearing it are spelled out precisely in the retake rules.
In practical terms, that means your real target isn't a mystery percentage - it's demonstrated, verifiable command of North Dakota's investigative licensing law and administrative rules well enough to answer confidently under exam conditions the first time. Because the exam is individually scheduled in Bismarck only after your eligibility review is complete, you have a built-in checkpoint: by the time you sit for the test, the Board has already confirmed your age, education, character, and hours documentation. The exam is the final gate, not the first one.
How the Exam Is Structured and Administered
The individual private-investigator licensing examination is administered or supervised by the NDPISB and scheduled on an individual basis in Bismarck - this is not a rolling, walk-in test center model. That has two direct implications for how you prepare:
- You get a fixed date, not a window. Once the Board approves your eligibility, your testing slot is set. There's limited room for "I'll take it again next week if I'm not ready" thinking - you want to walk in prepared the first time.
- The exam follows the same statutory and regulatory framework every candidate is held to. Because the Board administers or supervises the test directly, the content stays anchored to North Dakota's own licensing statute and rules rather than a generic multistate investigator curriculum.
For a full walkthrough of scheduling mechanics and deadlines, see ND-PI Exam Dates 2026: Testing Windows, Deadlines & Scheduling. If you're still mapping out whether you meet the underlying prerequisites - age, education, experience hours - before you even get to the exam stage, review ND-PI Requirements 2026: Eligibility, Prerequisites & How to Qualify first.
Key Takeaway
Because scheduling happens only after eligibility review, treat your exam date as a hard deadline for mastery - not a flexible target you can push back informally.
Content You Must Master to Clear the Bar
The Board's own preparation references point candidates to a narrow, specific set of documents rather than a broad investigative-skills curriculum. That narrowness is actually good news: it means your study time has clear boundaries. The core references are:
North Dakota Century Code, Chapter 43-30
This is the underlying licensing statute for private investigators and security professionals in North Dakota. Expect questions built directly from its definitions, licensing categories, and statutory obligations.
- Understand how the statute distinguishes individual licensees from registered investigative employees and detective agencies as separate categories
- Know the statutory basis for insurance, licensing, and enforcement authority
N.D. Admin Code Chapter 93-02-01.1
This chapter contains the administrative rules that flesh out licensing mechanics beyond the statute itself - the kind of procedural detail that shows up in scenario-style exam questions.
- Application documentation requirements, including fingerprint cards and photograph specifications
- Rules tied to experience verification and equivalencies approved by the Board
General Rules, Chapter 93-02-03
These are the conduct and operational rules that govern licensees once they're working - a frequent source of "what should the investigator do" style questions.
- Professional conduct expectations and grounds for discipline
- Operational boundaries, including the separate requirement for Board weapons certification before any armed work - a concealed-carry permit alone is not sufficient
For a section-by-section breakdown of how these references map onto exam-style questions, see ND-PI Exam Domains 2026: Complete Guide to All 0 Content Areas. And if you haven't yet built a study plan around the Board's own $40 optional study guide plus these statutory sources, start with ND-PI Study Guide 2026: How to Pass on Your First Attempt.
What Happens If You Fall Short: Retake Rules
This is one of the few places where North Dakota's rules give you a concrete, numeric answer - just not a "score." Instead, the consequence structure is time-based:
| Outcome | Retake Wait | What to Do in the Meantime |
|---|---|---|
| First exam failure | No sooner than 30 days after notice | Re-review weak statutory areas, revisit the Board study guide, reattempt with focused correction |
| Second or subsequent failure | One full year | Treat this as a serious reset - full re-study of 43-30, 93-02-01.1, and 93-02-03, not a quick refresh |
That one-year wait after a second failure is the single most important number in this entire process - far more consequential than any hypothetical passing percentage. It's the reason first-attempt readiness matters so much more here than it might for exams with unlimited quick retakes. For a deeper look at how difficult candidates generally find the material and where they tend to stumble, see How Hard Is the ND-PI Exam? Complete Difficulty Guide 2026 and ND-PI Pass Rate 2026: What the Data Shows.
Key Takeaway
A second failure costs you a full year before you can retest - plan your first attempt as if there's no meaningful safety net beyond the 30-day window.
Fees, Paperwork, and Logistics Tied to Your Pass
Passing the exam doesn't exist in isolation - it's one step inside a fee and paperwork sequence that the Board tracks closely. Under the fee schedule effective April 22, 2025, candidates should plan for:
- A $150 one-time application/testing fee
- A $225 individual license fee (prorated quarterly for initial licenses)
- A $40 criminal-record search fee
- An optional $40 Board study guide, purchased separately
Beyond fees, your application package must include two fingerprint cards, a passport-style photograph, and employment/experience verification documenting the standard 2,000 hours as a registered employee of a licensed agency (with Board-approved equivalencies possible in certain cases). Passing the exam without this paperwork in order won't get you licensed - and conversely, having perfect paperwork won't matter if you haven't passed within the required 12-month window before application. For the complete cost picture, including renewal, see ND-PI Certification Cost 2026: Complete Pricing Breakdown.
Once licensed, remember that the license itself expires September 30 every year, with a $225 renewal fee and a requirement to show current insurance documentation - individual licensees must maintain at least $300,000 in general-liability coverage including errors and omissions. Passing the exam is the entry point; staying compliant is the ongoing commitment.
A Focused Prep Timeline Built Around the Score You Need
Generic study techniques (spaced repetition, timed review blocks, teach-back drills) only help if they're pointed at the right material. Here's how to sequence a compressed prep window around the Board's actual reference documents rather than generic investigator trivia:
Statutory Foundation
- Read N.D.C.C. Chapter 43-30 in full; note licensing categories, definitions, and statutory obligations
- Cross-reference against the Board study guide's summary of the same statute
Administrative Rules
- Work through N.D. Admin Code 93-02-01.1, focusing on application, fingerprint, and experience-verification requirements
- Draft a checklist of every document your own application package will need
Conduct and Operational Rules
- Study Chapter 93-02-03 general rules, including conduct standards and the weapons-certification distinction from a concealed-carry permit
- Build scenario-style self-quiz questions from rule text
Integration and Timed Review
- Run full practice sessions mixing statute, admin code, and conduct-rule questions
- Identify remaining weak spots and re-read only those specific sections
If you want a single condensed reference to run through in the final days before your scheduled date, keep ND-PI Cheat Sheet 2026: One-Page Review of Must-Know Facts handy alongside timed practice runs on the main practice test platform.
Who Hires Licensed Investigators in North Dakota
Understanding what's actually being tested is easier when you understand why the licensing framework exists in the first place. Licensed detective agencies in North Dakota employ registered investigative employees, and both categories operate under the same NDPISB oversight structure that individual licensees do - which is exactly why the statute draws a clear line between "individual license," "registered investigative employee," and "detective agency" as separate licensing categories.

Frequently Asked Questions
The Board's public materials do not list a specific numeric passing percentage. What is clearly documented instead are the timing rules: the exam must be passed within the 12 months before your license application, and retake waits escalate after repeated failures.
After a first failure, you may reapply to retake no sooner than 30 days after receiving notice. After a second or subsequent failure, the required wait extends to one full year.
The exam must be passed within the 12 months preceding your license application, and your application must also include documentation of your investigative experience hours (or a Board-approved equivalency), along with fingerprint cards, a photograph, and employment verification. Both pieces need to be in place before licensing is finalized.
It's optional, sold separately for $40, but it directly aligns with the statutory and administrative code references the exam draws from, making it a natural companion to N.D.C.C. Chapter 43-30 and N.D. Admin Code Chapters 93-02-01.1 and 93-02-03.
No. Armed work requires a separate Board weapons certification. A concealed-carry permit, and passing the licensing exam alone, are not sufficient authorization for armed investigative work.
