What Is PE-M&M?

What PE-M&M Actually Is

PE-M&M is the shorthand used on this site for the Principles and Practice of Engineering (PE) examination in Metallurgical and Materials engineering. NCEES labels it "PE Metallurgical and Materials." It is the final written examination on the path to becoming a licensed Professional Engineer with a materials focus. It is a licensure exam, not a vendor certification, and passing it does not by itself make you a PE. Your state or territorial licensing board grants the license.

The exam is built for engineers who have already spent years working with metals, polymers, ceramics, and composites in real settings: selecting alloys, qualifying heat treatments, investigating failures, specifying coatings, or auditing supplier processes. It tests whether you can apply materials science to practical decisions with public-safety consequences, not whether you can recite textbook definitions.

If you want a deeper walkthrough of the terminology and how the credential is described, see our related explainers on PE-M&M meaning and what PE-M&M stands for.

Who Runs the Exam and Who Licenses You

Two different organizations matter, and candidates often confuse them.

• NCEES (National Council of Examiners for Engineering and Surveying) writes, administers, and scores the exam.
• Your state or territorial licensing board decides whether you are eligible to sit for the exam, collects its own application fees, and issues and renews the PE license.

Testing takes place in person at approved Pearson VUE test centers. Because the board controls eligibility, always read your board's rules before you pay any exam fees. The exact application steps, deadlines, and documentation vary by jurisdiction, and the PE-M&M requirements guide covers how those pieces fit together.

Exam Format, Timing, and Question Styles

The numbers

The exam is divided into two sections that share one testing clock. Once you submit a section, you cannot reopen it, so you need to finish checking your work before you submit. Every examinee in a given administration receives the same question set. For scheduling details and deadlines, see the PE-M&M exam dates guide.

Question types

You will see traditional multiple-choice questions alongside alternative item types:

• Multiple-correct (select all that apply)
• Point-and-click
• Drag-and-drop
• Numerical fill-in

Scored items receive correct or incorrect credit only. There is no partial credit on multi-part items, and there is no deduction for wrong answers, so you should never leave an item blank.

What you can bring

The exam is closed book. NCEES supplies a searchable electronic reference handbook during the test, and personal reference materials are prohibited. You may use one NCEES-approved calculator. Older third-party descriptions that call this an open-book exam, or that mention outdated course boilerplate, are superseded by the current NCEES specification (effective with the October 2024 exam). Practice with the handbook's search function before test day, because finding a table quickly is its own skill. A one-page recall aid such as our PE-M&M cheat sheet is useful for studying, but it cannot be brought into the exam room.

The Four Official Exam Domains

The NCEES specification organizes content under four numbered objectives. Each has an official range of questions rather than a published percentage weight, and the subtopics NCEES lists beneath each one are illustrative, not exhaustive. For a fuller breakdown, read our complete guide to all four content areas.

Which Materials Dominate the Exam

Separate from the four domains, NCEES gives an approximate distribution of questions that are specific to a material class. These are not domain weights, and the exam also includes material-independent and multi-material questions.

The takeaway is clear: ferrous metallurgy is the backbone of this exam. Steels, cast irons, and their heat-treatment and corrosion behavior deserve the largest share of your study time. That said, candidates from polymer, ceramic, or electronic-materials backgrounds should not ignore the ferrous material; those questions will appear regardless of your daily work. Likewise, metallurgists should allocate real time to polymers and ceramics, since a few well-prepared questions in those areas can separate a pass from a miss.

Eligibility and the Licensure Pathway

Eligibility is set by the licensing board you apply through, not by NCEES and not by a universal national rule. A common pathway looks like this:

1. Earn a bachelor's degree in engineering from an EAC/ABET-accredited program.
2. Pass the Fundamentals of Engineering (FE) exam.
3. Accumulate four years of acceptable engineering experience.
4. Pass the PE exam.

This sequence is common but is not a universal prerequisite for sitting for the exam. Some boards allow different routes, and requirements for approval timing, experience documentation, and references vary. If you use an NCEES Record for engineering, the application involves five references from U.S.-licensed engineers, but again, your board's application requirements control what you actually must submit. Start with your board's website, then confirm details using the eligibility and prerequisites guide.

Fees, Scoring, and Pass Rates

What it costs

The NCEES exam fee is $400 per attempt. Separate state board application fees can apply on top of that, and they vary by jurisdiction. Preparation materials, travel to a Pearson VUE center, and time away from work are additional costs. The certification cost breakdown helps you build a realistic budget.

How scoring works

Results are reported as pass or fail. To pass, your scaled score must meet the NCEES minimum-competence standard. NCEES does not publish a numerical passing score, so any article claiming a specific cut number is guessing. Because wrong answers carry no penalty, answer every item. See the passing score explainer for how scaled scoring is generally described.

Pass rates in context

NCEES's table, updated January 2026, shows a 49% first-time pass rate (43 examinees) and a 50% repeat pass rate (8 examinees). Those figures describe the prior October administration, not the upcoming October 2026 sitting. The examinee counts are small, so year-to-year swings should be read with caution. For more on interpreting these numbers, read the pass rate analysis and the difficulty guide.

Career Relevance and Who Hires

Materials engineers work in aerospace, automotive, energy, steel and metals production, heavy manufacturing, electronics, medical devices, and consulting or testing laboratories. Roles that benefit from a PE license often involve signing off on specifications, leading failure investigations, serving as an expert witness, or working in consulting and government-adjacent settings where licensure is valued or required for taking responsibility for engineering work.

For context, the Bureau of Labor Statistics reports a median annual wage of $112,860 for materials engineers (May 2025). That figure covers the whole occupation. It is not a PE-specific salary and does not measure what licensure adds to pay, so avoid reading it as a licensure premium. Our salary guide and the ROI analysis discuss how to weigh the value for your own situation, and the PE-M&M jobs page covers the kinds of roles where the license tends to matter.

Sequencing Your Preparation

Because this is a long, broad exam, the order in which you study matters more than any generic technique. Here is one sequencing approach tied to the blueprint:

Start with the official NCEES e-book practice exam ($59.95; 85 questions with solutions, based on the October 2024 specifications), and check NCEES's posted errata for the practice exam so you do not memorize a corrected answer. For a fuller plan, see the PE-M&M study guide, and for question practice in the exam's style, use our practice test site. If you want structured resources beyond self-study, our overview of PE-M&M training options may help, and you can drill timed sets on the main practice platform as exam day approaches.
