- MI-ME is the Michigan Master Electrician License Exam, administered by PSI for LARA's Bureau of Construction Codes.
- The exam has 76 questions, a 3-hour limit, and requires a 75% score to pass.
- It's open-book from the 2023 NEC, but only factory-tabbed, factory-highlighted code books are allowed - no handwritten notes.
- Eligibility requires being 22+, 12,000+ qualifying hours over 6+ years, with 4,000+ hours and 2+ years as a licensed journeyman.
What MI-ME Actually Is
MI-ME stands for the Michigan Master Electrician License Exam - the licensing test that qualifying journeyman electricians in Michigan must pass to earn a master electrician license. It is not a generic industry certification and it is not affiliated with any credential outside Michigan. The exam confirms that a candidate can plan, lay out, and supervise electrical installations at a level beyond journeyman-level installation work, and it is tied directly to the state's licensing statutes rather than a private trade association.
If you're just starting to research this path, it helps to first understand exactly MI-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify before you invest time studying content. Meeting the hour and license prerequisites is a prerequisite to even scheduling the exam through PSI.
Who Runs the Exam and Who Administers It
The Michigan Department of Licensing and Regulatory Affairs (LARA), through its Bureau of Construction Codes (BCC), oversees electrical licensing in the state, working alongside the Electrical Administrative Board. LARA does not write or proctor the exam itself - that responsibility belongs to PSI, the third-party testing provider that delivers the computer-based Master Electrician examination at approved testing centers.
Because these are two distinct organizations with two distinct roles, candidates typically manage two workflows: one with LARA for eligibility approval and licensing, and one with PSI for scheduling and sitting the exam. For a full breakdown of every dollar involved, see MI-ME Certification Cost 2026: Complete Pricing Breakdown.
Exam Format, Fees, and What You Bring to the Room
The Master Electrician examination is a 76-question, 3-hour, computer-based test administered through PSI. It is open-book, using the 2023 NEC as the primary reference, but "open-book" comes with strict conditions that trip up unprepared candidates.
- Allowed: Factory-produced markings, factory-installed highlights, and factory-installed tabs in your code book.
- Prohibited: Any candidate-added annotations, handwritten notes, or custom tabs - and the NEC Handbook is not allowed at all.
- Binding rule: Each printed act or rules document you bring must remain separate from the others and be secured with three staples along the left edge. Loose sheets are prohibited outright.
- Calculators: Personal calculators are prohibited; if a calculator is needed, one is provided at the testing center.
Key Takeaway
Prepare your reference materials weeks in advance. A code book with the wrong kind of tabs - or loose pages instead of stapled documents - can get materials rejected at check-in, wasting your $100 PSI fee and your testing appointment.
To hit 75% within the time limit, candidates need to be fast at navigating the 2023 NEC by table and article number, not just familiar with concepts.

The 15 MI-ME Domains
The official master examination description organizes tested installation and trade subject matter into 15 domains. These aren't arbitrary study categories - they reproduce the structure LARA and PSI use to define what's fair game on test day.
Domain 1: Grounding and Bonding
Grounding electrode systems, bonding jumpers, and equipment grounding conductor sizing are core to almost every scenario-based question.
- Distinguish grounding vs. bonding requirements by article
Domain 2: Overcurrent Protection
Breaker and fuse sizing rules, along with conductor protection coordination, show up across services, feeders, and motors questions alike.
- Know standard ampere ratings and rounding rules
Domain 3: Wiring Methods and Installations
Covers permitted wiring methods, support spacing, and installation conditions across different occupancy types.
- Match wiring method to environment (wet, damp, corrosive)
Domain 4: Boxes and Cabinets
Sizing, support, and accessibility requirements for enclosures used in branch circuit and feeder installations.
- Apply box sizing tables correctly under time pressure
Domain 5: Services
Service entrance conductor sizing, disconnect requirements, and clearance rules are frequently tested with multi-step calculations.
- Practice service-size calculations start to finish
Domain 6: Feeders
Feeder sizing and overcurrent protection build directly on load calculation skills from Domain 9.
- Link feeder sizing to demand factors
Domain 7: Motors and Motor Controls
Motor circuit conductor sizing, overload protection, and disconnect requirements are a dense, calculation-heavy domain.
- Memorize motor full-load current tables
Domain 8: Special Occupancies
Hazardous locations, health care facilities, and other special-occupancy rules that deviate from general wiring requirements.
- Identify occupancy-specific article triggers
Domain 9: Load Calculations
Dwelling and commercial load calculations underpin services, feeders, and panel sizing questions throughout the exam.
- Drill standard and optional calculation methods
Domain 10: Lighting
Branch circuit requirements, fixture support, and lighting load allowances.
- Know unit load per square foot values
Domain 11: Appliances
Branch circuit sizing and disconnecting means for fixed and portable appliances.
- Apply demand factors for multiple appliances
Domain 12: Box and Raceway Fill
Conductor fill calculations for boxes and raceways, a mechanically precise but formula-driven domain.
- Practice fill tables until they're automatic
Domain 13: Power Limited Circuits
Class 1, 2, and 3 circuit requirements and their separation from power wiring.
- Distinguish class-specific installation limits
Domain 14: General Electrical Trade Knowledge
Broader trade practices, plus the statutory and regulatory material tested alongside the NEC.
- Review the Skilled Trades Regulation Act and Stille-DeRossett-Hale Act basics
Domain 15: Electrical Theory
Ohm's law, power formulas, and circuit theory fundamentals that support calculation-based questions in other domains.
- Keep core formulas memorized cold
Beyond these 15 domains, the exam also draws on planning, laying out, and supervising electrical installations; the 2016 Skilled Trades Regulation Act (Public Act 407); the 1972 Stille-DeRossett-Hale Single State Construction Code Act (Public Act 230); and the Michigan Electrical Code Rules, Part 8. For a domain-by-domain study breakdown with more depth than this overview, see MI-ME Exam Domains 2026: Complete Guide to All 15 Content Areas.
Eligibility: Hours, Years, and Documentation
MI-ME isn't open to just anyone with an interest in electrical work. LARA sets firm prerequisites before you're even allowed to register for the PSI exam.
| Requirement | Minimum |
|---|---|
| Age | 22 years old |
| Total qualifying hours | 12,000 hours |
| Time span for those hours | At least 6 years |
| Hours as a journeyman | At least 4,000 hours |
| Time holding journeyman license | At least 2 years |
Applicants must also submit notarized employer experience documentation to verify qualifying hours. There's one meaningful shortcut, though: Michigan-licensed journeymen do not need to resubmit proof of experience that predates their Michigan journeyman license - LARA already has that on file. Detroit residents follow the city's own licensing process rather than the standard state pathway, so double-check which system applies to you before submitting paperwork.
Michigan does not extend automatic reciprocity for out-of-state electrical licenses. If you're licensed elsewhere, both your license and your qualifying experience go through individual review rather than automatic acceptance.
After You Pass: Licensing, Renewal, and Contracting
Passing the PSI exam is not the final step - it's the trigger for finishing your state application and paying the $50 initial master license fee. Once licensed, master electricians must renew annually by December 31 for a $50 renewal fee.
Holding a master license doesn't automatically let you run an electrical contracting business. That requires a separate electrical contractor license, which must be associated with a master electrician - though no additional contractor exam is required. One important limit: a master electrician can be associated with only one electrical contractor at a time, which matters if you're weighing job offers or planning to start your own contracting operation.
Employers hiring for roles tied to this license tend to include electrical contracting firms, industrial maintenance departments, and municipal or commercial construction operations that require a licensed master on staff or associated with their contractor license. If you're weighing whether the credential is worth pursuing given your career goals, Is the MI-ME Certification Worth It? Complete ROI Analysis 2026 and MI-ME Salary Guide 2026: Complete Earnings Analysis cover that angle, and MI-ME Jobs looks at where the license opens doors.
If You Don't Pass the First Time
LARA's retake policy is stricter than a simple "try again next month" approach. After a failed attempt, you must wait a full one year from the date of that failure before retesting. If you fail the exam twice within a two-year window, LARA requires completion of an approved educational course before you're permitted to sit again.
Key Takeaway
Because a single failure locks you out for a year, treat your first attempt as the one that counts. Build your prep timeline around domain weaknesses rather than rushing to a test date you're not ready for.
This is exactly why understanding the exam's real difficulty matters before you schedule. MI-ME Pass Rate 2026: What the Data Shows and MI-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling can help you plan a realistic timeline instead of guessing.
A Domain-Focused Way to Prepare
Generic study advice - timed sessions, flashcards, spaced review - only helps if it's mapped to MI-ME's actual content weight. Because load calculations, feeders, services, and motors all lean on similar formula skills, it makes sense to cluster them together early rather than studying domains in numerical order.
Calculation Core
- Domain 9 (Load Calculations), Domain 15 (Electrical Theory), Domain 5 (Services)
- Drill formulas until they're automatic under time pressure
Sizing and Protection
- Domain 2 (Overcurrent Protection), Domain 6 (Feeders), Domain 7 (Motors and Motor Controls)
- Practice full sizing problems end to end
Installation Rules
- Domain 1 (Grounding and Bonding), Domain 3 (Wiring Methods), Domain 4 (Boxes and Cabinets), Domain 12 (Box and Raceway Fill)
- Rehearse fast NEC table lookups
Remaining Domains and Timed Runs
- Domain 8, 10, 11, 13, 14 plus full-length timed practice
- Rehearse code-book navigation with your approved, factory-tabbed reference
For a structured week-by-week plan built specifically around this exam's timing and domain weight, see MI-ME Study Guide 2026: How to Pass on Your First Attempt. And when you're closer to test day, a condensed reference like MI-ME Cheat Sheet 2026: One-Page Review of Must-Know Facts can help consolidate the formulas and thresholds you'll need to recall quickly.
Running full-length timed practice sessions on MI-ME Exam Prep's practice test platform is one of the most direct ways to simulate the 76-question, 3-hour format before you're sitting in a PSI testing center. Repeated exposure to that pacing - roughly two and a half minutes per question - matters more for this exam than for untimed study formats, since code-book lookups eat into your available time. Working through domain-organized questions on the practice platform also helps surface which of the 15 domains need more attention before you schedule your PSI appointment.
Frequently Asked Questions
No. MI-ME refers specifically to the Michigan Master Electrician License Exam administered by PSI under LARA's Bureau of Construction Codes. It's tied to Michigan licensing statutes, not a national or private certification.
No. Only factory-produced markings, factory-installed highlights, and factory-installed tabs are permitted. Candidate-added annotations, handwritten notes, and custom tabs are prohibited, as is the NEC Handbook.
The PSI examination fee is $100. A separate $50 initial master license fee is paid with your state application to LARA, and licenses renew annually by December 31 for $50.
You must wait one year from your last failure before retesting. If you fail twice within a two-year period, LARA requires you to complete an approved educational course before sitting the exam again.
Not by itself. Operating an electrical contracting business requires a separate electrical contractor license associated with a master electrician, though no additional contractor exam is needed. A master can be associated with only one contractor at a time.
