- Your state or territorial licensing board, not NCEES, decides whether you may sit for the PE Mechanical: Machine Design and Materials exam.
- The common pathway is an EAC/ABET bachelor's degree, the FE exam, four years of acceptable experience, then the PE exam.
- NCEES charges US$400 per attempt; separate board application fees can apply on top of that.
- The exam has 80 questions, 8 hours of testing time, and is delivered in person at Pearson VUE test centers.
What "Requirements" Actually Means for This Exam
When candidates search for PE-M:MD&M requirements, they usually expect a single checklist. The reality is more layered. The Principles and Practice of Engineering - Mechanical: Machine Design and Materials exam is a licensure examination written and administered by the National Council of Examiners for Engineering and Surveying (NCEES). It is not a voluntary certification with a universal prerequisite list published by the exam maker. Instead, eligibility to sit for the exam is controlled by the specific licensing board you apply through.
That distinction matters. Two engineers with identical résumés can face different paperwork, different experience-verification rules, and different application timelines simply because they applied in different jurisdictions. The sections below separate what is common across most pathways from what you must confirm with your own board.
If you are still orienting yourself to the credential itself, start with What Is PE-M:MD&M? and then return here for the qualification details.
The Common Licensure Pathway, Step by Step
NCEES describes a widely used route to becoming a licensed professional engineer. It is the pattern most boards follow, though it is not a universal exam-sitting prerequisite, and some boards offer alternatives or additional conditions.
- Earn an engineering bachelor's degree from an EAC/ABET-accredited program. Accreditation is the cleanest way to satisfy educational requirements in most jurisdictions. Graduates of non-accredited or non-U.S. programs may need a credential evaluation or additional board review.
- Pass the Fundamentals of Engineering (FE) exam. Many candidates take it near graduation, while coursework is fresh. Some boards grant a designation such as Engineer Intern or Engineer-in-Training after you pass.
- Accumulate four years of acceptable engineering experience. "Acceptable" is defined by the board, and the experience typically must be progressive, engineering-level work, often verified by licensed engineers.
- Apply to your board and sit for the PE exam. Many boards approve you to test once your application is accepted, which in some jurisdictions can occur before the full experience requirement is complete. This varies, so confirm timing with your board.
| Step | Typical Requirement | Who Controls It |
|---|---|---|
| Education | EAC/ABET-accredited engineering bachelor's degree | Licensing board |
| FE exam | Pass the Fundamentals of Engineering exam | NCEES administers; board accepts |
| Experience | Four years of acceptable engineering experience (common pattern) | Licensing board |
| PE exam | Pass PE Mechanical: Machine Design and Materials | NCEES administers |
| License issuance | Board approval and fees | Licensing board |
Why Your Licensing Board Controls Eligibility
In the United States, engineering licensure is a state and territorial function. NCEES develops and scores the exam, but each board decides who qualifies to take it, how experience is documented, and when a license is issued. NCEES's own licensure resources at ncees.org/licensure direct candidates back to their board for binding requirements.
Practically, that means you should do the following before you spend money or study hours:
- Identify the board in the jurisdiction where you intend to be licensed, not necessarily where you live today.
- Read the board's current rules on education, FE exam acceptance, experience length, and experience verification.
- Ask whether the board lets you test before completing the full experience requirement, and whether your approval has an expiration window.
- Confirm whether the board accepts Machine Design and Materials as an exam option for a mechanical engineering license. Most do, but verify rather than assume.
Registration Mechanics and Fees
Registering for the exam generally involves two parallel tracks: your board's application and your NCEES exam account. The order depends on the board. Some require board approval before you can schedule, while others let you pay NCEES first and submit board materials separately.
Fees you should budget for
- NCEES exam fee: US$400 per attempt.
- Board application fees: These are separate and vary by jurisdiction. They may cover application review, license issuance, or both.
- Preparation materials: The official NCEES e-book practice exam is $59.95 and contains 80 questions with solutions, including 24 new questions and alternative item types aligned to the October 2025 specifications.
For a fuller budgeting picture, including retake economics, see PE-M:MD&M Certification Cost 2026: Complete Pricing Breakdown.
Scheduling
The exam is computer-based and offered year-round at approved Pearson VUE test centers, so there is no single annual exam date to chase. Your board's approval status and seat availability drive your timeline. For scheduling and deadline logistics, read PE-M:MD&M Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Exam Format You Must Be Ready For
Qualifying to sit is one thing; being ready for the specific delivery format is another. These are the exam-day facts that shape how you should prepare:
| Feature | Detail |
|---|---|
| Questions | 80 total, including unidentified unscored pretest items |
| Testing time | 8 hours |
| Appointment length | 9 hours, including a 2-minute nondisclosure agreement, 8-minute tutorial, and 50-minute scheduled break |
| Item types | Multiple-choice and alternative types: multiple-correct, point-and-click, drag-and-drop, numerical fill-in |
| Scoring | Correct/incorrect credit, no partial credit, no deduction for wrong answers |
| Reference materials | Closed book with a supplied searchable electronic reference handbook; personal references prohibited |
| Calculator | One NCEES-approved calculator |
| Units | SI and USCS |
| Delivery | In person at Pearson VUE; linear-on-the-fly exam assembly (LOFT) |
Two policy details deserve special attention. First, the two sections share the testing clock, and submitted sections cannot be reopened, so pacing and review discipline are part of the skill set. Second, because NCEES does not publish a numerical passing score, you cannot aim for a target percentage; you aim for competence across the blueprint. Read more in PE-M:MD&M Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Practice on the reference handbook interface, not just on your own notes. Since personal reference materials are prohibited, searching an electronic handbook quickly under time pressure is a trained skill, and it is part of what you are being tested on.
Technical Readiness: What the Six Domains Demand
No board checks whether you can size a bolted joint before approving your application, but the exam certainly does. The current blueprint is the NCEES specification effective beginning with the October 2025 examinations (the CBT32 file). Use it rather than the superseded 2020 outline or older eight-topic prep summaries, which may not match what you will see.
The specification publishes question-count ranges per domain rather than fixed percentage weights, and those ranges are the only official allocation data:
| Domain | Official Question Range |
|---|---|
| 1. Basic Engineering Practice | 11-17 |
| 2. Mechanics of Materials | 17-26 |
| 3. Mechanical Attachments | 9-14 |
| 4. Power Transmission | 9-14 |
| 5. Mechanical Components and Assemblies | 16-24 |
| 6. Supportive Knowledge (Machine Design and Materials) | 8-12 |
Domain 2: Mechanics of Materials
The largest range on the exam. Expect to move fluidly between stress, strain, and failure criteria, and to apply them to realistic machine members.
- Combined loading and stress transformation, including principal stresses
- Fatigue and failure theories applied to shafts and structural members
- Deflection and stiffness of beams and shafts
- Material properties and how they feed design margins
Domain 5: Mechanical Components and Assemblies
The second-largest range. This is where component-level design judgment gets tested.
- Selection and sizing of components such as springs, bearings, and seals
- How individual parts behave when integrated into assemblies
- Reading drawings and applying tolerance and fit concepts
Domain 3: Mechanical Attachments
Joint and connection analysis, where small details drive failure.
- Bolted joint behavior, preload, and load sharing
- Welded and other fastened connections
Domain 4: Power Transmission
Drivetrain elements and how power moves through a machine.
- Gears, belts, chains, shafts, and couplings
- Speed, torque, and efficiency relationships through a drive
Domains 1 and 6 round out the exam with Basic Engineering Practice and Supportive Knowledge. Neither carries the volume of Domains 2 and 5, but both reward candidates who do not neglect them. The illustrative subtopics in the official specification are not exhaustive, so treat any topic list, including those above, as a starting point. For a deeper walkthrough of each area, see PE-M:MD&M Exam Domains 2026: Complete Guide to All 6 Content Areas.
References, NCEES Records, and Experience Documentation
Experience is where many otherwise-qualified applicants stall. Boards typically want a documented, verifiable account of your engineering work, often supported by licensed engineers who can attest to it.
The NCEES Record program is a related but distinct tool. NCEES Record applications for engineering use five U.S.-licensed engineer references. This is not a universal exam-sitting prerequisite, and your board's application requirements control what you actually must submit. Some candidates build an NCEES Record because it simplifies applying to multiple jurisdictions later; others only need what their single board asks for. Details are at the NCEES Records program page.
Habits that make documentation painless:
- Keep a running log of projects, responsibilities, dates, and supervisors from your first day of experience.
- Record technical contributions in machine-design terms: what you analyzed, what you specified, what failed and how you addressed it.
- Stay in contact with the licensed engineers who supervised you, since reference gathering gets harder as time passes.
Sequencing Your Qualification and Preparation
Because qualification timelines and study timelines overlap, it helps to sequence them deliberately. This is the one place a schedule belongs, and it is tied to the question ranges above rather than a generic template.
Confirm eligibility and open applications
- Verify board rules, FE status, and experience documentation
- Download the October 2025 CBT32 specification
Domain 2: Mechanics of Materials
- Highest question range, so it earns the first and longest block
- Stress, fatigue, and deflection problems in both SI and USCS
Domains 3 and 4: Attachments and Power Transmission
- Joints, fasteners, gears, belts, shafts
- Builds directly on Domain 2 stress analysis
Domain 5: Mechanical Components and Assemblies
- Second-largest range; integrates earlier material
Domains 1 and 6, then full-length practice
- Close gaps, rehearse alternative item types and handbook searching
For a complete preparation framework beyond sequencing, see the PE-M:MD&M Study Guide 2026: How to Pass on Your First Attempt. To calibrate how much time you need, How Hard Is the PE-M:MD&M Exam? is a useful companion, and our practice tests let you rehearse the alternative item types before exam day.
Who Hires Machine Design and Materials Engineers
The Machine Design and Materials exam fits engineers whose daily work centers on how mechanical hardware is designed, sized, joined, and made to survive its loads. That describes a wide range of employers: manufacturers of industrial machinery and equipment, automotive and heavy-vehicle suppliers, aerospace and defense contractors, power-transmission and motion-control companies, product-development firms, and engineering consultancies that perform failure analysis or design review.
A PE license is also a practical requirement for roles that involve signing and sealing drawings or offering engineering services to the public, though how often that applies depends on the industry and jurisdiction. In many manufacturing settings the license is a credential that supports advancement rather than a hard job requirement.
On compensation, the U.S. Bureau of Labor Statistics reports a median annual wage of $104,110 for mechanical engineers as of May 2025. That figure is occupation-wide; it is not specific to this exam track and does not measure a PE licensure premium. For a candid look at the return on investment, read PE-M:MD&M Salary Guide 2026 and Is the PE-M:MD&M Certification Worth It?. You can also explore PE-M:MD&M Jobs for role-level detail.
After You Pass: Licensure, Renewal, and CPC
Passing the exam does not by itself make you a licensed engineer. Your board issues the license after confirming that your education, experience, and exam result satisfy its rules, and after any board fees are paid.
It is also worth being precise about what this credential is. The PE exam is a licensure examination, not a separately renewable NCEES certification. There is no NCEES expiration date on a passing result in the way a vendor certification might expire. Instead, the issuing state or territorial board sets PE license renewal periods and continuing-professional-competency (CPC) requirements. NCEES offers a CPC tracking service, described at ncees.org/ncees-services/cpc-tracking, that some licensees use to log continuing education. Check your own board's renewal calendar as soon as you are licensed, because renewal cycles and hour requirements differ by jurisdiction.
Key Takeaway
Treat your license as a board-managed credential from day one. Learn your renewal cycle, understand your CPC hour requirements, and start logging qualifying activities early rather than scrambling near the deadline.
Frequently Asked Questions
An EAC/ABET-accredited engineering bachelor's degree is the common pathway, but it is not a universal exam-sitting prerequisite. Your licensing board sets the education rules, and some boards have alternative routes or require extra review for non-accredited or foreign degrees. Confirm with your board before applying.
Passing the FE exam is part of the common licensure pathway, and most boards expect it. Because eligibility is controlled by the board you select, verify whether yours requires it, accepts an alternative, or grants any exceptions.
The common pattern is four years of acceptable engineering experience for licensure. However, some boards allow you to test before completing the full requirement, with the license issued only once experience is satisfied. This varies by jurisdiction, so check your board's rules on timing.
NCEES charges US$400 per attempt. Separate board application fees can apply and vary by jurisdiction, and you should also budget for preparation materials such as the $59.95 official NCEES e-book practice exam. See the certification cost breakdown for planning detail.
The exam is a licensure examination rather than a separately renewable NCEES certification. Your state or territorial board sets the license renewal period and continuing-professional-competency requirements, so those rules, not NCEES, determine when and how you renew.
Qualifying for this exam is a two-part project: satisfy your board's education, experience, and application rules, and build the technical depth the six domains require. Start with your board's published requirements, map your preparation to the official question ranges, and use realistic practice questions to confirm you are ready before you book your Pearson VUE appointment.
