What Is MN-ME?

What Is MN-ME?

MN-ME stands for the Minnesota Master Electrician License Exam - the state-administered test that qualifies an individual to hold a Class A Master Electrician personal license in Minnesota. In the Minnesota Department of Labor and Industry's (DLI) examination guide, this credential is coded AM. Unlike some trade exams that are outsourced to a third-party testing vendor, DLI administers this examination directly, which affects how you register, what materials you're allowed to bring, and how results and retest timing work.

This is a personal licensing exam, not a business credential. Passing it demonstrates that you understand the National Electrical Code (NEC), Minnesota's electrical statutes and rules, and applied electrical theory well enough to plan, supervise, and take responsibility for electrical installations at the master level. If you're mapping out your prep timeline, the MN-ME Study Guide 2026: How to Pass on Your First Attempt is a useful companion to this overview, and our practice test platform is built specifically around DLI's examination matrix rather than a generic electrical exam.

Who Governs and Administers the Exam

Two entities sit behind the MN-ME credential:

• Minnesota Department of Labor and Industry (DLI) - administers the examination, reviews applications, and issues licenses.
• Minnesota Board of Electricity - sets policy and reviews program data, including reporting pass rates in its public meeting minutes.

Because DLI runs the exam in-house rather than through a national testing vendor, the application, approval, and scheduling process is a linear DLI workflow: you submit documentation, DLI approves your eligibility, and only then can you schedule a seat. There's no separate "authorize to test" step handled by an outside company.

Eligibility Routes to Sit for the Exam

DLI recognizes three distinct paths to qualify for the Class A Master Electrician exam:

1. An electrical-engineering degree from an accredited college or university.
2. One year of work experience as a licensed journeyworker electrician.
3. Five years of practical experience in planning, laying out, supervising, and installing electrical wiring, apparatus, or equipment.

Whichever route applies to you, the sequence is the same: apply to DLI with your education and experience documentation, wait for approval, and only then schedule your exam date. Skipping ahead isn't possible - DLI will not seat a candidate who hasn't been approved. For a full breakdown of documentation requirements and how each route is evaluated, see MN-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Exam Format, Fees, and Materials

The mechanics of the MN-ME exam are specific and worth memorizing before test day:

The exam is open-book, but only with materials DLI provides at the test site: an untabbed softcover NEC, the applicable Minnesota Laws and Rules Booklet, and a basic calculator. Personal reference materials, tabbed code books, and electronic devices are prohibited. That means your study strategy has to build real code-navigation speed in an untabbed book, since you can't rely on your own highlighted or indexed copy during the actual test. For the exact scoring mechanics and what 70% really requires across 80 questions, read MN-ME Passing Score 2026: Exactly What You Need to Pass.

If you fail, DLI requires a 30-day wait after your failure notification before you can apply to retest. That waiting period is a good reason to treat your first attempt seriously rather than as a "practice run" - plan your prep around one strong attempt using resources like MN-ME Cheat Sheet 2026: One-Page Review of Must-Know Facts to lock in fast-recall facts before test day.

The 11 Exam Domains

DLI's examination matrix organizes MN-ME content into 11 domains that closely track the structure of the NEC itself, plus an applied-theory domain. Understanding this structure matters more for this exam than for most trade tests, because the domains are literally NEC chapters - so your code book familiarity and your domain familiarity are the same skill.

Because these domains map directly onto NEC chapters, a domain-by-domain walkthrough is one of the most efficient ways to prepare. For a deeper look at how each domain is weighted and tested, see MN-ME Exam Domains 2026: Complete Guide to All 11 Content Areas.

The 2026 NEC Transition

One detail candidates frequently get wrong: the code edition used on the exam and the code edition that applies to installations are not tied to the same date. Examinations taken on or after September 8, 2026 use the 2026 NEC. That is separate from the August 17, 2026 installation-code effective date, which governs which code edition applies to actual field work, not to the test itself.

What the Pass Rate Data Shows

The Minnesota Board of Electricity's April 14, 2026 meeting minutes reported 2026 year-to-date master pass rates of 44.7% by total examinations and 47% by test taker. These two figures use different denominators - one counts every exam attempt, the other counts unique test takers - so they aren't directly comparable to each other, and both predate the September 2026 NEC transition described above.

That distinction matters if you're trying to gauge your odds: a candidate who retests counts multiple times in the "by examinations" figure but only once in the "by test taker" figure.

Complete Difficulty Guide 2026.

Personal License vs. Contractor License

A common point of confusion: a personal Master Electrician license is separate from an electrical contractor business license. Passing the MN-ME exam and obtaining your master license qualifies you individually - it does not, by itself, license a business entity to contract electrical work in Minnesota. Contractor licensing is a distinct process with its own requirements. Keep this distinction in mind when researching what your license does and doesn't authorize you to do, especially if you're weighing career moves covered in MN-ME Jobs or Is the MN-ME Certification Worth It?

Renewal and Continuing Education

Once you hold the license, upkeep has its own fixed schedule:

• Master licenses expire on the last day of February in odd-numbered years.
• Renewal costs $93.
• Renewal requires 16 hours of approved continuing education per two-year period, including at least 12 NEC hours.

Because CE hours are heavily NEC-weighted, the same domain knowledge you build for the exam - particularly Domains 2 through 10, which trace the NEC chapters directly - continues to be relevant well after you pass. For a complete cost picture spanning application, exam, and renewal fees, see MN-ME Certification Cost 2026: Complete Pricing Breakdown.

Scheduling Your Prep Around the Domains

Because the 11 domains correspond to NEC chapters of very different sizes and complexity, a flat "study everything equally" plan wastes time. A more efficient approach front-loads the calculation-heavy material - Domain 3 (Wiring and Protection), Domain 10 (Tables), and Domain 11 (Applied Electrical Theory) - early enough to revisit them multiple times before test day, since these are the domains most likely to combine multiple code references into a single question.

Whatever pace you choose, timing your practice sessions to the actual 5-hour-30-minute, 80-question format matters more here than generic study techniques, since pacing yourself across that many calculation-heavy questions is itself a skill. Our full-length practice tests are built to mirror that structure so pacing issues surface before exam day instead of during it.

Who Hires MN-ME Credential Holders

A Class A Master Electrician license in Minnesota is typically the credential held by the individual who takes ultimate technical responsibility for electrical work - supervising journeyworkers, planning installations, and often serving as the qualifying individual behind a contracting business's electrical license. That makes it relevant to electrical contracting firms, facility maintenance departments with in-house electrical staff, and electricians moving from journeyworker status into supervisory or ownership roles.
