The Short Answer: What the Letters Mean
PE-NA&M stands for Principles and Practice of Engineering - Naval Architecture and Marine. It is the licensure examination that engineers take to earn a Professional Engineer (PE) license with a naval architecture and marine engineering focus. NCEES, the National Council of Examiners for Engineering and Surveying, writes and administers it. The official NCEES label for the exam is "PE Naval Architecture and Marine Engineering."
Break the name into its parts and the structure becomes clear:
- Principles and Practice of Engineering is the NCEES name for the PE exam family, the second exam in the traditional licensure sequence, after the Fundamentals of Engineering (FE) exam.
- Naval Architecture covers the design of the vessel itself: hull form, buoyancy, stability, resistance, structure, and arrangement.
- Marine covers the systems that make a vessel or offshore platform function: propulsion, piping, auxiliary machinery, electrical plant, and environmental compliance.
If you want the broader definition rather than the acronym breakdown, our companion pages What Is PE-NA&M? and PE-NA&M Meaning cover it from other angles.
Why the Acronym Confuses People
The letters "PE-NA&M" are compact, and compact acronyms get reused. Search for them and you may land on material about unrelated credentials. This site covers exactly one thing: the NCEES Professional Engineer exam in naval architecture and marine engineering. Nothing here describes a different certification, and no fee, date, or score on this page belongs to anything else.
What the Credential Actually Is
The PE-NA&M is a licensure examination, not a standalone certification. That distinction matters for how you think about it afterward:
- Passing the exam does not by itself give you a license. Your licensing board issues the license after you meet its education, experience, and application requirements.
- There is no separate NCEES renewal cycle for the exam result. Renewal periods and continuing-professional-competency requirements are set by the state or territorial board that issued your PE license.
- The exam is offered once a year as a single-day, computer-based test. The October 2026 administration is scheduled for October 27, 2026, and every examinee in that administration receives the same question set.
For a plain-language walkthrough of what the credential represents, see What Is PE-NA&M Certification? and PE-NA&M Certification.
The 13 Official Exam Objectives
The "NA" and the "M" in the acronym map directly onto how NCEES organizes the exam content. The current specification, effective beginning October 2025, lists 13 numbered domains. They split naturally into naval architecture domains, marine engineering domains, and common domains that apply to both. NCEES publishes question-count ranges for each, not fixed percentage weights, so the ranges below are the only official allocation figures.
| # | 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 (10-15 questions), followed by Structural Design (7-11). Second, the exam is deliberately broad: no single domain dominates, and the smaller domains still add up. For a domain-by-domain breakdown, read PE-NA&M Exam Domains 2026: Complete Guide to All 13 Content Areas.
Domain 1: Hydrostatics and Stability
This is the heart of naval architecture and the single biggest block of questions. Expect calculation-driven problems rooted in how a floating body behaves.
- Buoyancy, displacement, and center-of-gravity and center-of-buoyancy relationships
- Initial stability, metacentric height, and righting arm behavior
- Effects of loading, free surface, and weight changes on trim and heel
- Reading hydrostatic data and applying stability criteria
Domain 4: Structural Design
The second-largest range. Candidates should be comfortable reasoning about hull girder loads and local scantlings.
- Hull girder bending and shear under still-water and wave conditions
- Plating and stiffener sizing, and how classification rules shape the result
- Material properties and how they interact with Domain 12 topics such as welds and corrosion
Domains 6 through 10: The Marine Engineering Block
These five domains cover the systems side of the credential: propulsion and power generation, piping system design, auxiliary equipment selection, electrical systems, and environmental considerations. Together they account for a substantial share of the exam, so a candidate with a pure hull-design background cannot skip them.
- Matching prime movers, gearing, and propellers to a vessel's power demand
- Sizing pipes, selecting pumps, and reasoning about fluid system behavior
- Electrical load analysis and distribution on board
- Emissions, discharge, and other environmental compliance questions
How the Exam Is Built and Delivered
Understanding the format is part of understanding what the credential asks of you.
- Questions: 85 total, which include unidentified unscored pretest items. You cannot tell which ones do not count, so treat every question as live.
- Item types: multiple-choice plus alternative formats: multiple-correct, point-and-click, drag-and-drop, and numerical fill-in. Scored items earn correct or incorrect credit only, with no partial credit and no penalty for wrong answers.
- Time: 8 hours 30 minutes of testing time inside a 9 hour 30 minute appointment. The appointment includes a 2-minute nondisclosure agreement, an 8-minute tutorial, and a 50-minute scheduled break.
- Structure: two sections share one testing clock, and a submitted section cannot be reopened.
- Reference rules: closed book, with a supplied searchable electronic reference handbook. Personal reference materials are prohibited. You may use one NCEES-approved calculator.
- Units: both SI and USCS appear, so comfort converting between them is a practical skill.
- Location: in person at approved Pearson VUE test centers.
Because the handbook is searchable and supplied, much of the skill is knowing what you are looking for and how to find it quickly. The reference handbook itself sits behind an NCEES login, so we point you to the issuer rather than describe its contents. For tactics on handling the format, see the PE-NA&M Study Guide 2026: How to Pass on Your First Attempt, and for how the credential compares in difficulty, How Hard Is the PE-NA&M Exam?
Who Hires Licensed Naval Architects and Marine Engineers
The domains above mirror the actual work. Employers that need engineers who can do this work generally include:
- Shipyards and boatbuilders, where hull design, structure, arrangements, and outfitting happen in production.
- Naval architecture and marine engineering consultancies, which handle design, stability analysis, and regulatory submissions for owners and builders.
- Classification societies and regulatory bodies, where the Rules and Regulations domain is daily work.
- Offshore and ocean engineering firms, relevant to the Ocean Engineering domain.
- Government and naval programs, which employ engineers on vessel design, acquisition, and in-service support.
The U.S. Bureau of Labor Statistics reports a median annual wage of $112,230 for marine engineers and naval architects (May 2025). That figure covers the whole occupation. It is not a PE-specific salary and does not measure a licensure premium, and it is distinct from ship engineers who operate machinery. For a fuller treatment, see the PE-NA&M Salary Guide 2026 and PE-NA&M Jobs.
The Path to the Exam Room
The acronym describes an exam, but the exam sits inside a licensure process controlled by your licensing board. A common pathway looks like this:
- An engineering bachelor's degree from an EAC/ABET-accredited program.
- Passing the FE exam.
- Four years of acceptable engineering experience.
- Passing the PE exam.
That is a common pathway, not a universal rule. Eligibility to sit for the exam, and any approval you need first, are controlled by the specific board you apply through. Some boards sequence steps differently, so check with yours before assuming anything. If you use the NCEES Record, its engineering application asks for five references from U.S.-licensed engineers, but that too is not a universal exam-sitting prerequisite, and your board's application rules control. Our PE-NA&M Requirements 2026 page walks through qualification in more detail.
Fees, Pass Rates, and Pay: What Is Verified

Sequencing Preparation by Domain
Knowing what the letters stand for is step one; knowing how to work through the content is step two. One sensible way to order your preparation follows the dependencies between domains rather than their numbering. This is a sample framework, not an official curriculum, so adjust it to your own gaps.
Anchor in Domain 1
- Start with Hydrostatics and Stability because it has the largest question range and underpins Domains 2, 3, and 5.
- Work calculation problems until reading hydrostatic data feels routine.
Hull Behavior and Structure
- Cover Hydrodynamics, Ocean Engineering, and Structural Design (Domains 2, 3, 4).
- Pair Structural Design with Materials, Corrosion, Welds, and Connections (Domain 12) since they inform each other.
The Marine Engineering Block
- Work Domains 6 through 10 together: propulsion, piping, auxiliary equipment, electrical, environmental.
- Candidates from a hull-design background should spend extra time here.
Common Domains, Arrangements, and Full Practice
- Finish General Arrangements, Hull Outfitting, and Rules and Regulations (Domains 5, 11, 13).
- Take the official NCEES practice exam under timed conditions, using the handbook search the way you will on test day.
For a deeper plan, the PE-NA&M Study Guide 2026 goes into depth, and our PE-NA&M Cheat Sheet condenses the key facts. When you are ready to test yourself on realistic questions, try the PE-NA&M practice tests and see where your domain-level gaps are. Scheduling details live in PE-NA&M Exam Dates 2026.
Key Takeaway
Treat the acronym as a map. "NA" gives you five domains on the vessel itself, "M" gives you five on the systems aboard it, and three common domains tie them together. Preparing for only one half is the most common structural mistake on a broad exam like this.
