PE-M&MP Passing Score 2026: Exactly What You Need to Pass

TL;DR
  • NCEES does not publish a numerical passing score for PE Mining and Mineral Processing; you pass by meeting a minimum-competence standard.
  • Wrong answers are not penalized, so answer every one of the 85 questions, including any you must guess.
  • Domain 10 (Plant Equipment, Facilities, and Systems) carries the largest range: 9-14 questions.
  • The most recent dated table shows 57% first-time (47 examinees) and 50% repeat (10 examinees) pass rates.

Why There Is No Published Passing Number

Candidates searching for a passing score usually want a figure like "you need 70%" or "you need 56 out of 85." For the NCEES Principles and Practice of Engineering exam in Mining and Mineral Processing, that figure does not exist in any public NCEES document. The issuer states that your result is determined by whether your scaled score meets the NCEES minimum-competence standard, and it reports only pass or fail.

That wording matters. Anyone quoting a specific raw-score cutoff for this exam, whether on a forum, a course page, or a social post, is guessing or importing numbers from a different test. This article treats the official position as the only reliable one and focuses on what you can control: how the exam is built, where the question volume sits, and how to convert preparation into correct answers.

Practical consequence: Because no numerical target is published, "how many can I miss?" is the wrong planning question. Plan instead to be solidly competent across all 13 domains, with extra depth where question counts are highest. For a broader view of how demanding the exam is, see How Hard Is the PE-M&MP Exam? Complete Difficulty Guide 2026.

How NCEES Scoring Works for PE Mining and Mineral Processing

Minimum competence, not a curve

The passing standard is criterion-based. It reflects the level of knowledge NCEES judges necessary for a minimally competent engineer to practice in this discipline. Your result does not depend on how other examinees in your sitting performed. All examinees in an administration receive the same question set, and the standard is applied to your scaled score.

What a scaled score means in practice

A scaled score exists so that results remain comparable across administrations even when question sets differ in difficulty. You will not see the conversion. What you need to know is that raw correct answers feed into it, and that unscored pretest items are mixed into the 85 questions without being flagged. Treat every question as if it counts, because you cannot tell which ones do not.

The scoring rules that affect your behavior

  • No penalty for wrong answers. An unanswered question and a wrong answer score the same, so never leave a blank.
  • No partial credit. Scored items receive correct or incorrect credit only. On a multiple-correct item or a numerical fill-in, being nearly right earns nothing.
  • Pass/fail reporting. You will not receive a percentage that tells you how close you were by a simple count.

The absence of partial credit is the most underappreciated scoring rule. A drag-and-drop item that asks you to sequence a flow sheet or a numerical item that asks for a reserve tonnage is binary. This rewards clean unit handling and careful reading far more than rough estimation.

What the Dated Pass-Rate Table Does and Doesn't Tell You

NCEES publishes pass rates by exam and examinee category. The table available at the time of verification (updated January 2026) reflects the prior October administration, not the upcoming October 2026 sitting.

Examinee categoryPass rateExaminees
First-time takers57%47
Repeat takers50%10

Read these numbers with caution. The sample is small: 47 first-time examinees and 10 repeat examinees. In a pool this size, a handful of results moves the percentage noticeably, so year-to-year swings are expected and should not be over-interpreted. The repeat figure of 50% from just 10 people is especially thin. What the table does support is a modest, defensible conclusion: roughly half or more of examinees pass in a given administration, and the exam is passable with focused preparation, but a meaningful share of candidates do not pass on a given attempt. For more context on interpreting these figures, see PE-M&MP Pass Rate 2026: What the Data Shows.

Do not confuse pass rate with passing score. A pass rate tells you what fraction of examinees met the standard. The passing score is the standard itself, which NCEES does not disclose numerically. The two are unrelated figures and should never be used to derive each other.

The Format That Shapes Your Score

Your score is built from 85 questions delivered by computer at an approved Pearson VUE test center. The exam is single-day, in person, and closed book with a supplied searchable electronic reference handbook. Personal reference materials are prohibited, and you may use one NCEES-approved calculator. Questions may use SI or USCS units, so unit fluency is part of the skill being tested.

Item types you will face

  • Standard multiple-choice
  • Multiple-correct items, where you select more than one answer
  • Point-and-click items, such as selecting a location on a figure or diagram
  • Drag-and-drop items, such as ordering or matching
  • Numerical fill-in items, where you type a computed value

Because these alternative item types receive no partial credit, they punish sloppy process. Practice them specifically. The official NCEES e-book practice exam ($59.95, 85 questions with solutions, 104 pages, based on the October 2025 specifications) includes alternative item types and is the closest public approximation of the real format. Note that NCEES has posted errata for the practice exam (ISBN 978-1-947801-38-7), so check the corrections before trusting any solution that looks off.

Which blueprint governs

The October 2025 NCEES specification is the controlling document. Older descriptions that circulate online, such as an open-book format, an 80-question exam, or an 8-hour limit, do not reflect the current CBT exam. If a prep page conflicts with the NCEES specification, the specification wins. This is especially important for question-count ranges: the NCEES ranges for Domain 2 (3-5) and Domain 5 (8-12) differ from figures that appear on some third-party course pages.

Where the Points Live: Question Ranges by Domain

NCEES publishes question-count ranges rather than percentage weights, and this article does not convert them to percentages. The ranges still tell you where marks concentrate. Because the ranges overlap and sum to more than 85, treat them as indicators of relative emphasis, not exact allocations.

DomainNameQuestions
1Exploration: Methods and Techniques3-5
2Exploration: Site Geologic and Geotechnical Conditions3-5
3Exploration: Resources/Reserves5-8
4Mine Planning/Operations: Mining Methods and Layouts7-11

11Environment and Reclamation: Site, Mining, and Processing Characterization/Baseline3-5
12Environment and Reclamation: Environmental Management Systems5-8
13Environment and Reclamation: Reclamation Plan and Cost5-8

Domain 10: Mineral Processing: Plant Equipment, Facilities, and Systems

The largest range on the exam at 9-14 questions. A weak showing here is difficult to offset elsewhere.

  • Equipment selection and sizing logic across the circuit
  • Facility and systems considerations that connect equipment to throughput
  • Calculations that must be handled in consistent units, since numerical items give no partial credit

Domain 5: Mine Planning/Operations: Mine Equipment, Facilities, and Systems

The second-largest range at 8-12 questions, and the one where outdated third-party figures most often disagree with NCEES.

  • Mine equipment, facilities, and supporting systems
  • Applied equipment and systems reasoning rather than recall of catalog facts

General engineering skills, engineering economics and cost management, laws and regulations, and facility construction are cross-domain considerations. They are not separate domains, so expect them to appear embedded inside questions from the 13 numbered areas. A reclamation cost question in Domain 13 may lean on economics, for example. For a domain-by-domain walkthrough, see PE-M&MP Exam Domains 2026: Complete Guide to All 13 Content Areas.

Key Takeaway

Domains 10 and 5 together account for a 17-26 question range between them. Prioritize them without neglecting the smaller domains: the narrow ones (Domains 1, 2, and 11 at 3-5 each) still add up across the exam, and with no partial credit and no published cutoff, ignoring any domain is a gamble you cannot price.

Pacing Across Two Sections on One Clock

You have 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. The exam is delivered in two sections that share the testing clock, and submitted sections cannot be reopened.

Those two facts combine into a pacing rule that directly affects your score. Because a submitted section is locked, you must finish reviewing flagged items before you submit, not after. And because both sections draw from one clock, time you save in the first section is available in the second, while time you overspend is gone.

  • Answer every item in a pass, flagging anything numerically heavy or ambiguous.
  • Return to flagged items with remaining time, finishing your review before you submit the section.
  • Never leave a blank, since an incorrect answer and a skipped one score identically.
  • On multiple-correct and numerical items, double-check units and selection count before moving on, because there is no partial credit to rescue a near miss.

Across 85 questions in 8.5 hours, the clock is generous on average, which means that time pressure is rarely the limiting factor for prepared candidates. Errors from rushed unit conversions and misread item instructions are the bigger risk. Slow down on alternative item types in particular.

A Study Sequence Built Around Score Value

Rather than a generic schedule, sequence your preparation by where question volume and difficulty concentrate. The outline below is one reasonable way to allocate effort across the 13 domains. Adjust it for your professional background: a candidate from a processing plant will need more time on mine-side domains, and a mine planner will need more time on mineral processing.

Weeks 1-2

Baseline and the heavy domains

  • Take a diagnostic against the official practice exam to expose weak domains
  • Begin Domain 10 (Plant Equipment, Facilities, and Systems) and Domain 5 (Mine Equipment, Facilities, and Systems), the two largest ranges
Weeks 3-4

Mine planning core

  • Domain 4 (Mining Methods and Layouts), Domain 6 (Ground Control), and Domain 7 (Mine Planning and Site Layout)
  • Practice economics and cost reasoning that surfaces inside these questions
Weeks 5-6

Processing and exploration

  • Domain 9 (Process Flow Sheets) and Domain 8 (Laboratory/Pilot Testing and Results)
  • Domain 3 (Resources/Reserves), then Domains 1 and 2 for exploration methods and site conditions
Weeks 7-8

Environment, reclamation, and simulation

  • Domains 11, 12, and 13, including reclamation plan and cost calculations
  • Full-length timed practice using only the reference handbook and one approved calculator

Because the handbook is searchable and electronic, part of your preparation should be learning to locate what you need quickly in the same kind of tool. Where possible, use the official NCEES exam-prep resources to rehearse that workflow.

Fees, Eligibility, and Retake Realities

What a single attempt costs

The NCEES exam fee is $400 per attempt. Separate state or territorial board application fees can apply on top of that, and they vary by board. Add the cost of prep materials, such as the $59.95 official e-book practice exam, when budgeting. Because the exam is offered once per year, a failed attempt typically means waiting for the next annual administration, which makes a first-attempt pass worth planning for carefully. A fuller breakdown is in PE-M&MP Certification Cost 2026: Complete Pricing Breakdown.

Who can sit for it

Eligibility and any required approval are controlled by the licensing board you select, not by NCEES alone. A common licensure pathway is an EAC/ABET-accredited engineering bachelor's degree, the FE exam, four years of acceptable engineering experience, and then the PE exam. That is a common pattern, not a universal prerequisite, so confirm your board's rules before you apply. See PE-M&MP Requirements 2026: Eligibility, Prerequisites & How to Qualify for details.

Timing and what happens after

The exam is scheduled for October 27, 2026, as an annual single-day computer-based administration. Confirm current scheduling details on the NCEES page, and see PE-M&MP Exam Dates 2026: Testing Windows, Deadlines & Scheduling. Passing leads to licensure through your board. It is a licensure examination, not a separately renewable NCEES certification; the issuing state or territorial board sets renewal periods and continuing-professional-competency requirements.

Why the investment is usually weighed

The BLS reports a median annual wage of $106,220 (May 2025) for mining and geological engineers, including mining safety engineers. That figure is occupation-wide. It is not a PE-specific salary and it does not measure a licensure premium, so do not read it as a promised raise. For a candid look at the trade-offs, see Is the PE-M&MP Certification Worth It? Complete ROI Analysis 2026.

Frequently Asked Questions

What is the passing score for the PE Mining and Mineral Processing exam?

NCEES does not publish a numerical passing score. You pass by achieving a scaled score that meets the NCEES minimum-competence standard, and results are reported only as pass or fail.

Are wrong answers penalized on the exam?

No. There is no deduction for incorrect answers, and scored items receive correct or incorrect credit with no partial credit. Answer every question rather than leaving any blank.

What does the latest pass-rate data show?

The NCEES table updated January 2026 shows a 57% first-time pass rate (47 examinees) and a 50% repeat pass rate (10 examinees). It reflects the prior October administration, and the small sample sizes mean the figures can swing from year to year.

How many questions are on the exam, and do they all count?

There are 85 questions, including unscored pretest items that are not identified. Because you cannot tell which ones are unscored, treat every question as if it counts toward your result.

Which domains should I prioritize to maximize my score?

Domain 10 (Plant Equipment, Facilities, and Systems, 9-14 questions) and Domain 5 (Mine Equipment, Facilities, and Systems, 8-12) have the largest ranges. Still prepare across all 13 domains, since no cutoff is published and every domain contributes scored items.
