Why the HI-PD Exam Has No Published Percentage Domains
If you've studied for other state licensing exams, you're probably used to seeing a content outline that says something like "Domain 1: 20%, Domain 2: 15%." The Hawaii Private Detective License Exam doesn't work that way. The Board of Private Detectives and Guards, operating under the Department of Commerce and Consumer Affairs (DCCA), Professional and Vocational Licensing Division, has not released a percentage-weighted blueprint for the written test administered by PSI Services, LLC.
Instead, the Board publishes a study-reference list - two textbooks and a handful of statute and rule citations. That list is a reference sheet, not an examination blueprint, and it's important not to treat it as one. Some prep resources online blur this distinction, or worse, mix in guard-specific material that doesn't apply to the detective exam. This guide treats the reference list exactly as the Board intends: a map of subject matter, not a percentage breakdown.

The Board's Official Study References
The Board-linked detective study-reference list names two specific texts:
The Process of Investigation (2nd Edition) - Sennewald & Tsukayama
This text covers the fundamentals of conducting an investigation from intake to conclusion - interviewing, evidence handling, surveillance planning, and report writing. Expect the written exam to draw on investigative methodology and professional judgment scenarios rather than pure memorization.
- Interview and interrogation technique fundamentals
- Case planning and documentation standards
- Report writing that will hold up to scrutiny in a licensing or legal context
Security Investigations, A Professional's Guide - Larry G. Nicholson
This reference broadens the scope from case-level investigative work into professional practice: client relationships, workplace investigations, and the operational realities of running or working within an investigative business.
- Professional standards and client management
- Workplace and corporate investigation contexts
- Practical procedures tied to licensed investigative work in Hawaii
Both books are explicitly detective-focused. If you come across guard-training material while searching for prep content, set it aside - it belongs to a separate registration track, not the individual private detective license.
Statutory and Administrative Rule Content Areas
Beyond the two textbooks, the reference list points candidates to specific chapters of Hawaii law. These function as your de facto "content areas" even though the Board doesn't weight them numerically.
| Statute / Rule | Subject Matter |
|---|---|
| HRS Chapter 703 | Penal code defenses (justification, use-of-force principles) |
| HRS Chapter 396 | Occupational safety and health law |
| HRS Chapter 463 | Private detectives and guards licensing law |
| HRS Chapter 436B | General professional and vocational licensing provisions |
| HAR Title 16, Chapter 97 | Administrative rules for private detectives and guards, including exam and oral review provisions |
HRS Chapter 463 and HAR Title 16, Chapter 97 deserve special attention - they're the actual licensing law and rules governing your profession, including the examination and oral review process itself. If you only have time to master one statutory area cold, make it these two.
Key Takeaway
Treat HRS 463 and HAR 16-97 as your highest-priority statutory reading - they directly govern the exam, the oral review, and licensure itself, not just general practice.

Exam Format, Scoring, and the Oral Review
The written exam is administered by PSI Services, LLC, but only after the Board has approved your application and issued an examination-approval letter. You cannot register with PSI until you have that letter in hand, and the Board advises allowing up to 24 hours after receipt before registration access opens.
The minimum passing score is 75%. Passing the written exam is not the finish line, though - candidates must also appear before the Board in person for an interview and oral review before a license is issued. This two-stage structure (written exam, then oral review) is one of the more distinctive features of the HI-PD process compared to purely written licensing exams elsewhere.
For the exact scoring mechanics and what the 75% threshold means in practice, read HI-PD Passing Score 2026: Exactly What You Need to Pass. If you're curious how outcomes typically play out for candidates, see HI-PD Pass Rate 2026: What the Data Shows.
Registration Timeline and Fee Mechanics
Getting to test day involves more than opening a book. The application itself has hard deadlines and layered fees:
- A complete application must reach the Board at least 30 days before the meeting at which it will be reviewed.
- The March 2026 individual application lists a $50 application fee and a $50 examination fee, both payable to DCCA.
- Experience verification - documenting the equivalent of four years of full-time investigational work - must be notarized.
- Applicants must pass Hawaii and FBI fingerprint-based criminal history checks and meet character and fitness standards.
- Before license issuance, a surety bond of at least $5,000 must be in place and maintained while actively licensed - note that the bond amount and the premium you pay the surety are two different numbers.
Initial individual license issuance fees depend on where you land in the licensing cycle: $280 if issued from July 1 of an even-numbered year through June 30 of the following odd-numbered year, or $108 if issued from July 1 of an odd-numbered year through June 30 of the following even-numbered year. Renewal falls by June 30 of every even-numbered year, with the Board listing an active individual renewal total of $344 for the July 1, 2026 through June 30, 2028 period.

Building a Study Plan Around the Reference List
Because the Board doesn't assign weights to its content areas, the smartest approach is to sequence your study around the reference list itself - treating each book and statutory chapter as its own study block rather than guessing at emphasis.
Investigative Fundamentals
- Read The Process of Investigation cover to cover, focusing on interviewing and case documentation
- Summarize each chapter in your own words to test retention
Professional Practice
- Work through Security Investigations, A Professional's Guide
- Note where professional-practice concepts overlap with Hawaii licensing law
Statutory Deep Dive
- Study HRS Chapter 463 and HAR Title 16, Chapter 97 in full
- Skim HRS 703, 396, and 436B for context and definitions
Review and Oral-Review Prep
- Run practice questions to simulate the PSI test format
- Rehearse explaining your investigative experience aloud - you'll need to speak confidently in front of the Board
This kind of scheduling only works if you understand what each week is building toward.

Who Hires HI-PD License Holders
Licensed private detectives in Hawaii typically work in corporate investigations, insurance claims investigation, legal support for attorneys, background screening, and independent agency work once principal-detective and agency requirements are met. The four-year investigational experience requirement built into the application process means most candidates arrive with existing law enforcement, military investigative, or private security backgrounds rather than starting from zero.

Frequently Asked Questions
No. The Board of Private Detectives and Guards publishes a study-reference list - two textbooks plus statute and rule citations - rather than a percentage-weighted content outline. Treat the reference list as your subject map, not a scored breakdown.
The minimum passing score is 75%. Passing the written exam alone isn't enough - you must also appear before the Board for an interview and oral review before a license is issued.
Focus on HRS Chapter 463 and HAR Title 16, Chapter 97 first, since these directly govern private detective licensing, the examination, and the oral review process. HRS 703, 396, and 436B provide important supporting context.
After two consecutive failed attempts, a 90-day waiting period applies starting from the date of your last failed exam before you can register to retest with PSI.
You must obtain the Board's examination-approval letter first, and PSI registration access typically opens within 24 hours after you receive that letter - not before.
