- WY-ME stands for Wyoming Master Electrician, administered through ICC Exam 701 and Pearson VUE.
- It's a 100-question, open-book, four-option multiple-choice exam given in a 5-hour window.
- Wyoming rule 041-5, section 5-3(e) requires a 75% score to pass the master exam.
- Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits and Conductors make up 51% of questions.
What the Letters Actually Stand For
WY-ME is shorthand for the Wyoming Master Electrician License Exam. "WY" is Wyoming, and "ME" is Master Electrician - the highest individual electrical license level the state issues before a person can operate as a licensed working master under a Wyoming electrical contractor. The exam itself is cataloged by the International Code Council as Contractor/Trades examination 701, Wyoming Master Electrician, and it's delivered on computer through Pearson VUE testing centers.
If you've landed here after searching several near-identical acronyms, it's worth being precise: this site, and this article, cover only the Wyoming credential tied to the state's electrical licensing statute - not any other trade, healthcare, or professional designation that happens to share the same three-letter shorthand. Every fact below comes from Wyoming's own licensing rules and the ICC exam bulletin governing this specific test.
Who Issues the WY-ME Credential
The Wyoming Department of Fire Prevention and Electrical Safety, through its State Electrical Board, is the licensing authority behind WY-ME. The board sets eligibility, approves candidates before they can schedule a seat, and enforces the passing standard written into Wyoming Administrative Rule 041-5. ICC develops and scores the exam content itself, and Pearson VUE runs the actual testing appointments once state approval is granted.
This two-step gatekeeping - state approval first, then ICC/Pearson VUE scheduling second - is one of the most misunderstood parts of the process. Candidates sometimes assume they can register with Pearson VUE the moment they hit their experience hours. In reality, the state has to sign off on your application first. For a full breakdown of who qualifies and when, see WY-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Don't book a Pearson VUE slot until the Wyoming State Electrical Board has approved your application - approval, not experience alone, unlocks scheduling.
How the Exam Itself Is Built
Once you're approved, the exam format is straightforward but unforgiving on time management. WY-ME is a computer-based, four-option multiple-choice, open-book exam consisting of 100 questions to be completed within a 5-hour window. Open-book doesn't mean easy - it means the exam expects you to navigate code references quickly under pressure rather than memorize text verbatim.
Permitted references include the listed National Electrical Code, Ugly's Electrical References, the NEC Handbook, Ferm's Fast Finder Index, and Tom Henry's Key Word Index, all subject to ICC's reference rules. Those references must be bound; pre-existing ink notes, highlighting, and permanent tabs are allowed, but you cannot write in your references during the exam itself. You'll also need an approved basic battery-operated, nonprogrammable, nonprinting calculator and valid government-issued photo ID that matches your exam registration exactly.
A passing score is 75%, set by Wyoming rule 041-5, section 5-3(e). If you don't clear that bar, you must wait ten days before you're eligible to retest. For the exact scoring mechanics and what a 75% threshold means in practice, read WY-ME Passing Score 2026: Exactly What You Need to Pass.
Domains Behind the Acronym
Knowing what WY-ME "stands for" administratively is one thing; knowing what it tests is another. The 100 questions are distributed across nine content domains, and three of them carry more than half the weight of the entire exam.
Domain 5: Wiring Methods and Materials (19%)
The single heaviest domain. Covers conductor types, raceway selection, cable systems, and installation rules across residential, commercial, and industrial contexts.
- Know NEC Chapter 3 wiring method articles cold
Domain 2: Services and Service Equipment (16%)
Service entrance conductors, disconnects, grounding and bonding at the service, and equipment ratings.
- Expect scenario questions on service sizing
Domain 4: Branch Circuits and Conductors (16%)
Circuit loading, conductor ampacity, overcurrent protection coordination, and derating.
- Practice ampacity table lookups under time pressure
Together, Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits and Conductors account for 51% of the exam - more than half your score rides on these three areas. The remaining domains still matter and can't be ignored: General Knowledge (12%), Equipment and Devices (10%), Special Occupancies, Equipment, and Conditions (12%), Motors and Generators (8%), Feeders (4%), and Control Devices (3%). For a domain-by-domain walkthrough of what each area actually tests, see WY-ME Exam Domains 2026: Complete Guide to All 9 Content Areas.
| Domain | Weight |
|---|---|
| Wiring Methods and Materials | 19% |
| Services and Service Equipment | 16% |
| Branch Circuits and Conductors | 16% |
| General Knowledge | 12% |
| Special Occupancies, Equipment, and Conditions | 12% |
| Equipment and Devices | 10% |
| Motors and Generators | 8% |
| Feeders | 4% |
| Control Devices | 3% |
Eligibility: Getting to "ME" Status
Because WY-ME is a "master" level exam, eligibility is built for experienced electricians, not entry-level workers. The standard path requires eight years (16,000 hours) of electrical experience, including at least four years (8,000 hours) working as a licensed journeyman, plus 576 hours of approved classroom instruction. You'll need to document work across residential, commercial, and industrial settings through employer and license verification paperwork.
There's also an alternative route: ten years (20,000 hours) as a licensed journeyman or master combined with Chief Electrical Inspector approval, which can substitute for the classroom requirement. Either path leads to the same exam and the same 75% passing standard.
One structural detail candidates often miss: the individual master license itself is not a contractor license. A working master must be employed by a current Wyoming electrical contractor to legally practice under that title. If you're mapping out the full qualification path before you apply, WY-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through the documentation piece in more detail.
Fees, Renewal, and the Fine Print
The exam fee is $115. Passing gets you to the initial master license, which costs $200. Renewal runs $100 and happens every third year by July 1, requiring 16 approved continuing-education hours, including at least eight NEC hours earned during that license period.
Miss the July 1 renewal deadline and you get a grace period through August 15 with a $50 late fee attached. Miss that window entirely, and the rule is unforgiving: you're required to sit for re-examination rather than simply pay to reinstate. That's a meaningful consequence for a licensing deadline, and it's worth calendaring well in advance.

Turning the Acronym Into a Study Plan
Once you understand what WY-ME actually tests, preparation stops being abstract. Because Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits and Conductors carry 51% of the exam, your study calendar should weight those three domains disproportionately in the weeks before your test date - not split evenly across all nine.
High-weight domains first
- Drill Wiring Methods and Materials and Services and Service Equipment
- Practice open-book navigation speed, not just recall
Branch Circuits and remaining mid-weight domains
- Cover Branch Circuits and Conductors, Special Occupancies, and General Knowledge
- Time yourself against the 5-hour, 100-question pace
Lower-weight cleanup and reference tabbing
- Review Motors and Generators, Feeders, and Control Devices
- Confirm reference books are properly tabbed and bound per ICC rules

Key Takeaway
Weight your last month of study toward the three domains that make up 51% of the exam before spending equal time on lower-weight areas like Control Devices or Feeders.
FAQ
WY-ME stands for Wyoming Master Electrician License Exam, formally cataloged as ICC exam 701, administered through Pearson VUE under the Wyoming Department of Fire Prevention and Electrical Safety.
No. WY-ME certifies an individual as a licensed master electrician. To legally practice as a working master, that individual must be employed by a current Wyoming electrical contractor; the personal license does not authorize contracting on its own.
The exam has 100 multiple-choice questions with four answer options each, and candidates are given 5 hours to complete it in a computer-based, open-book format at a Pearson VUE testing center.
The August 19, 2025 ICC bulletin specifies NEC 2023 for this exam, even though Wyoming has adopted NEC 2026 for installations effective July 1, 2026. Confirm your assigned edition with the state before purchasing code books.
You must wait ten days before you're eligible to retest. There's no fixed limit mentioned in the rule beyond that waiting period, but each attempt requires re-registration through the standard fee and scheduling process.
