PE-M&M Certification

What the PE Metallurgical and Materials Exam Actually Is

The PE-M&M certification is not a vendor badge or a membership credential. It refers to the Principles and Practice of Engineering examination in Metallurgical and Materials, one of the discipline-specific professional engineering exams produced by the National Council of Examiners for Engineering and Surveying (NCEES). Passing it is one required step toward becoming a licensed Professional Engineer in the materials field.

That distinction matters for how you plan. Because this is a licensure examination rather than a separately renewable certification, there is no "PE-M&M renewal" from NCEES. Once you hold a PE license, your state or territorial board sets the renewal cycle and any continuing-professional-competency requirements. If you are new to the terminology, our explainers on what PE-M&M is and what PE-M&M stands for cover the basics, and the broader overview at PE-M&M certification places the exam in context.

Who Administers It and How Testing Works

NCEES writes and scores the exam, and Pearson VUE delivers it at approved Pearson test centers. The exam is offered once a year as single-day, computer-based testing, and the current administration is scheduled for October 28, 2026. Every examinee in that administration receives the same question set. For deadline and scheduling details, see PE-M&M exam dates.

Testing is in person. Your appointment runs 9 hours 30 minutes, which breaks down as follows:

The exam is divided into two sections that share a single testing clock. Once you submit a section, you cannot reopen it, so budget your time deliberately and do not submit a section until you are finished with it.

Exam Format, Question Types and Reference Rules

The exam contains 85 questions in total, and that count includes unscored pretest items that are not identified for you. You should treat every question as if it counts.

Item types you will encounter

• Multiple-choice questions with a single best answer
• Multiple-correct items where more than one option must be selected
• Point-and-click items, such as selecting a region on a figure or diagram
• Drag-and-drop items, such as ordering process steps or matching terms
• Numerical fill-in items where you type a computed value

Scored items receive correct or incorrect credit only, with no partial credit. That is especially important for multiple-correct items: selecting only some of the right options earns nothing. There is also no deduction for wrong answers, so never leave a question blank.

What you can bring

The exam is closed book. You work from the supplied, searchable electronic reference handbook, and personal reference materials are prohibited. You may use one NCEES-approved calculator. Questions appear in both SI and USCS units, so unit fluency is part of the test. Note that older third-party descriptions of this exam as "open book" are outdated; the current October 2024 NCEES specification takes precedence. Because the handbook is searchable, learning to find formulas and data tables quickly is a genuine skill worth practicing before exam day.

The Four Objectives and How Questions Are Allocated

The NCEES specification, effective beginning with the October 2024 examination, organizes the exam into four numbered objectives. NCEES does not publish fixed percentage weights; it publishes question-count ranges instead. For a deeper walk-through, see our complete guide to all four PE-M&M content areas.

The illustrative topics above are not exhaustive; the official specification at NCEES is the authority on scope. Note also that a question can sit across domains. A failure analysis item may require structure knowledge, a processing history and characterization data all at once.

The Material-Specific Mix: Ferrous Dominates

Beyond the four objectives, NCEES publishes an approximate distribution of material-specific questions by material class. These are not domain weights, and the exam also includes material-independent and multi-material questions.

The practical implication is clear: steels and cast irons deserve the largest share of your study hours. Iron-carbon phase relationships, hardenability, tempering, stainless and tool steel families, and ferrous corrosion and failure modes should be second nature. Nonferrous work (aluminum, copper, titanium, nickel-base and similar alloys) is the clear second priority.

Eligibility and the Licensure Pathway

Here the details depend entirely on where you intend to be licensed. Eligibility to sit for the exam, and any required approval, is controlled by your selected licensing board, not by NCEES. A common pathway in the United States looks like this:

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

This is a common route, not a universal prerequisite for sitting for the exam. Some boards allow the exam earlier or use different experience rules, so confirm directly with your board before building a timeline. Our breakdown of PE-M&M requirements and how to qualify goes deeper.

If you use the NCEES Record service to compile your credentials, note that applications for engineering use five U.S.-licensed engineer references. That is a feature of the Records program, not a universal condition for taking the exam, and your board's application requirements control.

Fees, Scoring and Pass-Rate Context

What it costs

NCEES charges $400 per exam attempt. Separate board application fees can apply on top of that, and these vary by jurisdiction. Budget separately for study materials and any travel to a Pearson test center. A full pricing walk-through is in our PE-M&M certification cost guide.

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 be skeptical of any site that claims an exact cut figure. See PE-M&M passing score for how the standard is applied.

Reading the pass-rate data carefully

The NCEES table updated in January 2026 reports a 49% first-time pass rate across 43 examinees and a 50% repeat pass rate across 8 examinees. This reflects a prior October administration, not the upcoming October 2026 sitting. With cohorts this small, a swing of a few candidates moves the percentage noticeably, so treat the figures as a rough indicator rather than a stable forecast. For more on interpreting the numbers, read PE-M&M pass rate: what the data shows and how hard the PE-M&M exam is.

Career Context and Hiring Landscape

Materials engineers work wherever the performance of a material limits a product or process: metals producers and foundries, heat treaters, aerospace and automotive suppliers, energy and power generation, oil and gas, infrastructure, polymer and composite manufacturers, failure analysis and testing laboratories, and consulting firms. A PE license is most valuable where engineers sign and seal work, serve as expert witnesses, or take responsibility for public-safety-related decisions, such as consulting and failure investigation.

On compensation, the U.S. Bureau of Labor Statistics reports a median annual wage of $112,860 for materials engineers as of May 2025. That figure covers the whole occupation and is not a PE-specific salary or a measured licensure premium, so do not read it as the payoff of passing this exam. For a fuller discussion, see the PE-M&M salary guide, the ROI analysis, and our overview of PE-M&M jobs.

Sequencing Your Preparation Around the Blueprint

You do not need an elaborate system, only a sequence that mirrors how the exam is built. Structure feeds Processing, Processing feeds Performance, and Characterization verifies all of it. The outline below suggests an order, with more detail in the PE-M&M study guide.

For practice material, the official NCEES e-book practice exam costs $59.95 and contains 85 questions with solutions, including 14 new questions and alternative item types, based on the October 2024 specifications. Check the posted errata for the practice exam as well, since NCEES has published corrections. Supplement it with additional PE-M&M practice questions to build volume across all four domains.
