ExploreAbout this exam
The Principles and Practice of Engineering (PE) exam in Mining and Mineral Processing is one of the more than 20 PE discipline exams offered by NCEES. It is a computer-based licensure exam that tests for a minimum level of competency in the discipline; NCEES describes the PE exam generally as designed for engineers who have gained a minimum of four years of post-college work experience in their chosen engineering field. Candidates typically apply through their state licensing board, then register and schedule through their MyNCEES account at an NCEES-approved test center.
The content spans the working core of the discipline: mining methods and mine planning, geotechnical engineering and ground control, drilling and blasting, mine ventilation and environmental control, materials handling and mineral processing, and mine economics, health, and safety. Because items mix conceptual judgment with multi-step calculations, preparation should combine worked problems under time pressure with a careful read of the official exam specifications, the NCEES calculator policy, and the Examinee Guide.

What you'll study
About PE Mining preparation
What format is the PE Mining and Mineral Processing exam?
It is a computer-based exam delivered at NCEES-approved test centers. You register and schedule through your MyNCEES account, selecting an exam location and then an available date; NCEES notes you can browse dates at other approved centers if the first options don't suit you. Bring only a calculator allowed under the NCEES calculator policy.
How difficult is the exam?
It is a competency exam, not a ranked competition. NCEES describes the PE as testing for a minimum level of competency and designs it for engineers with at least four years of post-college experience. The challenge is breadth: you need working fluency in ground control, blasting, ventilation, processing, and economics rather than depth in a single specialty.
How many attempts am I allowed?
NCEES policy provides one attempt per testing window and no more than three attempts in a 12-month period. That makes a throwaway first sitting expensive in calendar time, so build a study plan that treats the first attempt as the real one.
When are results released?
NCEES states results are typically available within 7–10 business days, with an email notification instructing you to view them in MyNCEES. All results are reported as pass or fail. If you fail, you receive a diagnostic report showing performance by major topic, which is the most useful input for planning a retake.
In what order should I study the topics?
Front-load the quantitative areas that feed many items: slope and support stability, blast design, airflow and ventilation-network calculations, and processing mass balances. Then add economics and cost estimation, since production and cost questions combine with technical topics. Finish with integrated mine-planning problems and timed mixed sets.
What are the most common failure modes?
Unit discipline tops the list: metric versus imperial, tonnes versus short tons, and per-shift versus per-day production bases. Others are skipping the economics material, memorizing equipment specifications instead of practicing multi-step design calculations, and never rehearsing under time pressure, which leaves easy questions unanswered at the end.
Do I need board approval before I can register?
Registration requirements are set by licensing boards, and NCEES directs candidates to select their state or territory to see exam-specific information and requirements. For exams administered under agreements with Canadian associations, the association must approve you before you register with NCEES to schedule.
Are testing accommodations available?
Yes. NCEES states that reasonable accommodations are available for examinees who meet certain eligibility criteria and sufficiently document their request. Start the request early, because documentation review takes time and can affect which testing window you can realistically target.
Where should I get the official exam specifications?
NCEES publishes exam prep materials, the Examinee Guide, the calculator policy, and scoring information as resources on its website. Use the official specifications to set your study scope and topic order; third-party practice material, including this page, should supplement the published topic list rather than replace it.
