What Does PE-NA&M Mean?

TL;DR
  • PE-NA&M means Principles and Practice of Engineering - Naval Architecture and Marine, an NCEES licensure exam.
  • The exam has 85 questions, 8 hours 30 minutes of testing time, and 13 numbered objectives.
  • Hydrostatics and Stability carries the largest question range: 10-15 questions.
  • The NCEES fee is US$400 per attempt; your licensing board controls eligibility and application fees.

Decoding the Acronym: What PE-NA&M Actually Stands For

On this site, PE-NA&M is shorthand for the Principles and Practice of Engineering - Naval Architecture and Marine examination. NCEES's official label for it is "PE Naval Architecture and Marine Engineering." Read the pieces in order and the acronym unpacks itself:

  • PE - Principles and Practice of Engineering, the exam that follows the Fundamentals of Engineering (FE) exam on the path to a Professional Engineer license.
  • NA - Naval Architecture: how a vessel or floating structure is shaped, kept afloat, kept stable, moved through water, and built to survive its loads.
  • M - Marine (engineering): the machinery, piping, electrical, and auxiliary systems that make a vessel work.

The distinction matters because the same letters appear in other contexts. This article covers only the engineering licensure exam. It is not a vendor certification, a training course, or a membership credential. Passing it is one requirement toward a state or territorial PE license, and the license itself is issued by a licensing board, not by NCEES.

If you want the short-form versions of this explanation, our companion pages on what PE-NA&M stands for and the PE-NA&M meaning cover the same ground, and What Is PE-NA&M? adds the licensure context.

Who Writes, Administers, and Licenses

Three different parties touch this exam, and candidates often blur them together:

PartyRole
NCEES (National Council of Examiners for Engineering and Surveying)Develops and administers the exam, publishes the specifications, and reports pass/fail results
Pearson VUEDelivers the computer-based exam at approved Pearson test centers
Your state or territorial licensing boardDecides whether you are eligible to sit, handles your application, issues the PE license, and sets renewal and continuing-competency rules
SNAME (Society of Naval Architects and Marine Engineers)Publishes a secondary preparation guide; does not set the exam blueprint or domain weights
Exam versus license: The PE-NA&M exam is not a separately renewable NCEES certification. Once you hold a PE license, renewal periods and continuing-professional-competency requirements come from the issuing board, so check that board's rules rather than looking for an "exam renewal" date.

The 13 Objectives Behind the Letters

The current NCEES specification, effective beginning October 2025, lists 13 numbered objectives. These are official exam objectives, not a preparation curriculum, and the illustrative subtopics beneath each are not exhaustive. NCEES publishes question-count ranges rather than percentage weights, so we report them as ranges and do not convert them into percentages.

13Common: Rules and Regulations5-8

The naval architecture block (Domains 1-5)

Domain 1: Hydrostatics and Stability

The heaviest-ranged domain at 10-15 questions. Expect the core vessel-floating-and-staying-upright material.

  • Buoyancy, displacement, and center-of-gravity/center-of-buoyancy relationships
  • Intact and damage stability reasoning
  • Curves of form and how weight changes shift trim and heel

Domain 4: Structural Design

The second-largest range at 7-11 questions. It rewards candidates who can move between hull-girder loading and local scantling checks.

  • Longitudinal and transverse strength concepts
  • Plating and stiffener sizing logic
  • Reading structural requirements from class-style rules

Domains 2, 3, and 5 round out the architecture side: hydrodynamics (resistance and propulsion-related flow), ocean engineering (the wave, wind, and environmental loading side), and general arrangements (how spaces, tanks, and equipment are laid out within the hull).

The marine engineering block (Domains 6-10)

These domains move from the hull to the systems inside it: propulsion and power generation, piping system design, auxiliary equipment selection, electrical systems, and environmental considerations. A candidate with a naval architecture background often finds this block unfamiliar; a mechanical or marine engineer often finds Domain 1 the harder climb. The complete guide to all 13 content areas breaks each one down in more depth.

The common block (Domains 11-13)

Hull outfitting, materials/corrosion/welds/connections, and rules and regulations apply to everyone regardless of background. Domain 13 deserves special attention because rules-based questions often depend on knowing where to look, and you will be working from a supplied reference handbook rather than from memory.

A note on the SNAME portal: Older SNAME learning-portal pages describe the subject matter as 21 topics, and SNAME's own study guide uses its own preparation categories and percentages. Those are useful secondary study aids, but they are not NCEES domain weights. The 13 objectives above come from the NCEES specification and should control how you plan.

What Sitting the Exam Looks Like

PE-NA&M is a single-day, computer-based exam offered annually. The scheduled date is October 27, 2026, and every examinee in the administration receives the same question set. The format details:

  • 85 questions, which include unidentified unscored pretest items you cannot spot, so treat every question as live.
  • 8 hours 30 minutes of testing time within a 9 hour 30 minute appointment. The appointment includes a 2-minute nondisclosure agreement, an 8-minute tutorial, and a 50-minute scheduled break.
  • Question types: traditional multiple-choice plus alternative item types: multiple-correct, point-and-click, drag-and-drop, and numerical fill-in.
  • Scoring: scored items receive correct or incorrect credit with no partial credit, and there is no deduction for wrong answers. Leaving a question blank can only hurt you.
  • Closed book with a supplied searchable electronic reference handbook. Personal reference materials are prohibited.
  • One NCEES-approved calculator.
  • In-person testing at an approved Pearson test center, with both SI and USCS units appearing.

Key Takeaway

The exam has two sections that share a single testing clock, and a submitted section cannot be reopened. Budget your time across both sections before you start, and do not submit a section until you are done reviewing it.

The alternative item types change how you should practice. A numerical fill-in question gives you no answer choices to back-solve from, and a multiple-correct item can't be passed by eliminating one wrong option. Our difficulty guide explains why these formats feel harder than their multiple-choice counterparts, and the free PE-NA&M practice tests let you rehearse them under realistic conditions.

Fees, Eligibility, and Who Decides

The NCEES exam fee is US$400 per attempt. Separate application fees charged by your licensing board can apply on top of that, so the all-in cost depends on your jurisdiction. For a full breakdown, see the PE-NA&M certification cost guide.

Eligibility is the part candidates most often assume incorrectly. The selected licensing board controls who may sit for the exam and whether any approval is required. A common pathway looks like this:

  1. An engineering bachelor's degree from an EAC/ABET-accredited program
  2. Passing the FE exam
  3. Four years of acceptable engineering experience
  4. Passing the PE exam

That sequence is a common licensure pathway, not a universal prerequisite for sitting the exam. Some boards allow candidates to sit earlier or through alternate routes; others are stricter. Likewise, NCEES Records applications for engineering use five U.S.-licensed engineer references, but that is a Records-program requirement, not a universal exam-sitting rule. Start with your board's application instructions, then work backward. The requirements guide walks through this in detail.

Reading the Pass-Rate Table Honestly

NCEES reports pass/fail rather than a numerical score. The passing criterion is a scaled score meeting the NCEES minimum-competence standard, and NCEES does not publish a numerical passing score, so be skeptical of any site that quotes one. More on that in our passing score explainer.

The most recent NCEES table (updated January 2026) shows:

GroupPass RateExaminees
First-time takers63%46
Repeat takers38%8

Two cautions. First, these figures come from a prior October administration, not the upcoming October 27, 2026 sitting. Second, the cohort is small: 46 first-time and 8 repeat examinees. Small groups swing a lot from year to year, so treat the percentages as a rough orientation rather than a prediction. The pass rate analysis goes deeper on how to interpret them.

Where the Credential Gets Used

The PE license in this discipline is relevant wherever vessels, floating structures, and marine systems are designed, reviewed, or approved. That typically means shipyards and ship design firms, naval and government programs, classification and regulatory work, offshore and ocean-engineering projects, and marine consulting. Exact employer lists vary and no single database covers them all, so check current job postings rather than relying on a generic list.

On compensation, 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 describes design professionals rather than ship engineers who operate machinery aboard vessels. If you want to weigh whether licensure pays off for your situation, see the salary guide and the ROI analysis, and browse our notes on PE-NA&M jobs.

Sequencing Preparation Around the Blueprint

You do not need a generic study template here; you need an order that reflects the exam's structure. Because question ranges, not percentages, define the blueprint, a sensible approach is to front-load the biggest ranges and use the supplied reference handbook early so its layout becomes second nature.

Early weeks

Domain 1 first, then Domain 4

  • Hydrostatics and Stability (10-15) and Structural Design (7-11) are the two largest ranges
  • Work calculation-style problems, including numerical fill-in with no answer choices
Middle weeks

Your weaker side of the architecture/marine divide

  • Naval architects: Domains 6-9 (propulsion, piping, auxiliaries, electrical)
  • Marine engineers: Domains 2, 3, and 5 (hydrodynamics, ocean engineering, arrangements)
Late weeks

Common domains and full-length practice

  • Domains 11-13: outfitting, materials/corrosion/welds, and rules and regulations
  • Run timed sets using the electronic handbook and an approved calculator

For official practice material, NCEES sells an e-book practice exam for $59.95: 85 questions with solutions, including alternative item types, 123 pages, based on the October 2025 specifications. The SNAME study guide (July 2026 edition) is a useful secondary resource but does not control the blueprint. The full study guide expands on resources and pacing, and the cheat sheet condenses the must-know facts.

Because people search this topic in many different ways, here is how the common phrasings map to the same exam:

If you only have time for one next step, take a timed practice test and see which of the 13 domains slows you down.
