What the Letters Actually Stand For
On this site, PE-NA&M refers to one specific thing: the Principles and Practice of Engineering - Naval Architecture and Marine examination. The "PE" is the Professional Engineer license examination family, the "NA" is Naval Architecture, and the "M" is Marine, covering marine engineering. NCEES uses the official label "PE Naval Architecture and Marine Engineering" for the exam, and you will see that wording on the NCEES exam page and in the exam specifications.
The acronym is an informal shorthand. People type it in different ways, which is why you will find overlapping explainers such as What Is PE-NA&M?, What Does PE-NA&M Stand For?, and What Does PE-NA&M Mean? on this site. They all describe the same exam: the discipline-specific, principles-and-practice test that engineers take late in the path toward a Professional Engineer license in naval architecture and marine engineering.
Who Administers the Exam and How You Sit for It
The exam is issued by the National Council of Examiners for Engineering and Surveying (NCEES), the same body behind the FE and the other PE disciplines. NCEES writes and scores the exam, but your state or territorial licensing board decides whether you are eligible to sit for it. That split is the single most misunderstood point about the credential, and it is covered in depth in PE-NA&M Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Testing logistics
- Provider: Pearson VUE, at approved Pearson test centers, in person.
- Frequency: the exam is offered once a year as single-day computer-based testing. The scheduled date is October 27, 2026, and every examinee in an administration receives the same question set.
- Fee: US$400 per attempt to NCEES. Your board may add its own application fees, so budget for both. A fuller breakdown is in PE-NA&M Certification Cost 2026: Complete Pricing Breakdown.
- Units: questions use both SI and USCS units, so you need to be comfortable converting and working in either.
The clock
The appointment runs 9 hours 30 minutes, but actual testing time is 8 hours 30 minutes. The difference covers a 2-minute nondisclosure agreement, an 8-minute tutorial, and a 50-minute scheduled break. The exam is delivered in two sections that share the testing clock, and once you submit a section you cannot reopen it. That rule changes how you pace yourself: finish your review of section one before you submit it, because there is no second pass.

The 13 Official Domains Behind the Name
The name "Naval Architecture and Marine" is a compression of thirteen official exam objectives published in the NCEES specification effective beginning October 2025. NCEES does not publish fixed percentage weights for them. Instead it publishes question-count ranges, and those ranges are the honest guide to where the points are. The headings below are exam objectives, not a suggested curriculum order.
| # | Domain | Question range |
|---|---|---|
| 1 | Naval Architecture: Hydrostatics and Stability | 10-15 |
| 2 | Naval Architecture: Hydrodynamics | 6-9 |
| 3 | Naval Architecture: Ocean Engineering | 4-6 |
| 4 | Naval Architecture: Structural Design | 7-11 |
| 5 | Naval Architecture: General Arrangements | 5-8 |
| 6 | Marine Engineering: Propulsion and Power Generation | 6-9 |
| 7 | Marine Engineering: Piping System Design | 5-8 |
| 8 | Marine Engineering: Auxiliary Equipment Selection | 5-8 |
| 9 | Marine Engineering: Electrical Systems | 5-8 |
| 10 | Marine Engineering: Environmental Considerations | 4-6 |
| 11 | Common: Hull Outfitting | 4-6 |
| 12 | Common: Materials, Corrosion, Welds, and Connections | 4-6 |
| 13 | Common: Rules and Regulations | 5-8 |
Two things stand out. First, Hydrostatics and Stability has the largest range at 10 to 15 questions, with Structural Design next at 7 to 11. Together they form a large share of the exam. Second, the marine engineering domains are individually modest but collectively substantial: Propulsion and Power Generation, Piping System Design, Auxiliary Equipment Selection, Electrical Systems, and Environmental Considerations add up to a big block. A naval architect who ignores them, or a marine engineer who ignores hull-form topics, leaves points on the table.
Domain 1: Hydrostatics and Stability
The heaviest domain. Expect to compute and reason about floating-body behavior.
- Displacement, center of buoyancy, center of gravity, and metacentric height
- Intact and damage stability, righting arms, and free-surface effects
- Trim, heel, and loading-condition calculations
Domain 4: Structural Design
The second-largest range. Hull-girder and local strength reasoning dominates.
- Longitudinal strength, bending moment, and section modulus
- Plating and stiffener scantlings
- Load cases and the link back to classification-society rules
Domain 12: Materials, Corrosion, Welds, and Connections
A smaller range, but the topics recur inside structural and piping questions.
- Steel and aluminum selection for marine service
- Galvanic and general corrosion control, including cathodic protection
- Weld types, joint design, and fatigue-sensitive details
The fuller walk-through of every objective, with illustrative subtopics, is in PE-NA&M Exam Domains 2026: Complete Guide to All 13 Content Areas. Keep in mind that the subtopics listed in the NCEES specification are illustrative rather than exhaustive.
What the Questions Look Like
The exam contains 85 questions, and that count includes unidentified, unscored pretest items. You cannot tell which are pretest, so treat every question as if it counts. Formats are not limited to classic multiple choice. You should expect:
- Standard multiple-choice items
- Multiple-correct items, where more than one option must be selected
- Point-and-click items, where you mark a location on a figure or diagram
- Drag-and-drop items
- Numerical fill-in items, where you enter a computed value
Scored items receive correct or incorrect credit with no partial credit, and there is no deduction for wrong answers, so never leave an item blank. For multiple-correct and fill-in formats, that all-or-nothing rule means a nearly right answer earns nothing. Practice finishing calculations cleanly rather than stopping when you are "close."
Closed book, with a handbook
The exam is closed book. You work from the supplied, searchable electronic reference handbook and use one NCEES-approved calculator; personal reference materials are prohibited. The practical consequence is that your preparation should include learning to find things quickly in the handbook's search interface, not just knowing the physics. The login-gated handbook is the version to train against.
Where the Credential Shows Up in Hiring
The PE-NA&M path leads into a narrow, specialized profession. The U.S. Bureau of Labor Statistics groups marine engineers and naval architects together and reports a median annual wage of $112,230 as of May 2025. That figure is occupation-wide. It is not a PE-specific salary and it does not measure a licensure premium, and it describes design and engineering roles rather than the shipboard engineers who operate machinery. For context on earnings and return, see PE-NA&M Salary Guide 2026: Complete Earnings Analysis and Is the PE-NA&M Certification Worth It? Complete ROI Analysis 2026.
The kinds of employers that need engineers who can credibly sign off on marine work include:
- Shipyards and ship designers, where stability, structure, and arrangements work is the core product
- Naval architecture and marine engineering consultancies, which handle conversions, surveys, and design review
- Classification and regulatory bodies, where Rules and Regulations knowledge (Domain 13) is daily work
- Offshore and ocean engineering firms, which draw on Ocean Engineering (Domain 3) and Hydrodynamics
- Government and defense organizations, which employ naval architects and marine engineers on vessel programs
A PE license matters most where an engineer must take legal responsibility for a design, so it carries the most weight in consulting and in roles that approve or certify work. More on roles is in PE-NA&M Jobs.
A License, Not a Renewable Certification
It is common to see this exam described as a "certification," and our own site has pages like PE-NA&M Certification and What Is PE-NA&M Certification? that use that everyday language. Precisely, though, passing this exam is one step toward a professional engineering license, issued by a state or territorial board, not a separately renewable NCEES credential.
That has real consequences:
- Renewal and continuing professional competency are set by the board that issued your license, not by NCEES.
- Eligibility is set by the board you apply through. A common pathway is an EAC/ABET-accredited engineering bachelor's degree, the FE exam, four years of acceptable engineering experience, and then the PE exam, but this is not a universal prerequisite for sitting the exam.
- NCEES Records applications for engineering use five U.S.-licensed engineer references. That is an NCEES records service requirement, not a universal exam-sitting prerequisite, and your board's own application rules control.
Key Takeaway
Before you pay anyone, confirm with your own licensing board what it requires and when it will approve you to test. The board's rules, not a general web page, decide your timeline.
The Numbers Worth Knowing
Two of the most-searched numbers are the passing score and the pass rate. Here is what is actually published.
Passing score
NCEES reports results as pass or fail, based on a scaled score that meets its minimum-competence standard. It does not publish a numerical passing score, and any page that gives you an exact cut number is guessing. Our explainer on this is PE-NA&M Passing Score 2026: Exactly What You Need to Pass.
Pass rate
In the NCEES table updated January 2026, the pass rate was 63% for first-time examinees (46 examinees) and 38% for repeat examinees (8 examinees). Those figures come from the prior October administration, not the upcoming October 2026 sitting. The samples are small, so read them as a rough signal rather than a stable benchmark. For interpretation, see PE-NA&M Pass Rate 2026: What the Data Shows and How Hard Is the PE-NA&M Exam? Complete Difficulty Guide 2026.
| Item | What is published |
|---|---|
| Questions | 85, including unscored pretest items |
| Testing time | 8 hours 30 minutes (9 hours 30 minutes appointment) |
| NCEES exam fee | US$400 per attempt |
| Scoring | Pass/fail on a scaled score; no numerical cut published |
| Wrong-answer penalty | None |
| First-time pass rate | 63% (46 examinees) |
| Repeat pass rate | 38% (8 examinees) |
Sequencing Your Prep by Domain
You do not need an elaborate method here, just a sensible order that follows the question ranges. Start with the domains that pay the most and that other topics lean on, then fill in the marine engineering systems, and finish with regulations and timed practice. The sample below assumes an eight-week window and is a starting point, not a prescription.
Hydrostatics and Stability (Domain 1)
- Rework stability and trim calculations until they are routine
- Practice damage-stability and free-surface problems with the handbook search open
Structural Design and Hydrodynamics (Domains 4 and 2)
- Hull-girder strength and scantling calculations
- Resistance, propulsion interaction, and seakeeping basics
Marine Engineering Block (Domains 6-10)
- Propulsion, piping, auxiliary equipment, electrical systems, and environmental topics
- Pair each system with its governing regulation so Domain 13 is learned in context
Common Domains and Full-Length Practice (Domains 3, 5, 11, 12, 13)
- Ocean engineering, general arrangements, hull outfitting, materials and welds, rules
- One or more full timed sessions, rehearsing the shared two-section clock

One caution on sources: the SNAME study guide is a useful secondary preparation resource, but it is not the controlling blueprint. Its categories and percentage statements do not establish official NCEES domain weights. Anchor your planning to the NCEES specification and use SNAME material as supplementary context. When you want timed, exam-style repetition, use the PE-NA&M practice exam alongside the official NCEES practice product.
