- You need 75% correct on 100 questions in 5 hours to pass under Wyoming rule 041-5, section 5-3(e).
- Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits and Conductors make up 51% of the exam.
- The exam fee is $115, and a failed attempt requires a ten-day wait before retesting.
- Confirm whether Pearson VUE has you scheduled on NEC 2023 or a later edition before buying code books.
How the WY-ME Exam Actually Works
The Wyoming Master Electrician License Exam (WY-ME) is administered through Pearson VUE as ICC Contractor/Trades examination 701. It is a computer-based, open-book test made up of 100 four-option multiple-choice questions, and you get 5 hours to finish. That's roughly three minutes per question, which sounds generous until you're flipping through a bound NEC and Ferm's Fast Finder Index looking for a table reference under time pressure.
Because this is an open-book exam, the questions aren't designed to test memorization of code section numbers. They're designed to test whether you can navigate the NEC quickly and apply it correctly to a scenario - sizing a service, calculating a branch circuit load, identifying the right wiring method for a hazardous location. If you've never timed yourself finding an answer in the code book, that's the first gap to close.
If you want the full breakdown of exactly how the 75% threshold is calculated and what it means in practice, read WY-ME Passing Score 2026: Exactly What You Need to Pass. Short version: you need at least 75 correct answers out of 100, per rule 041-5, section 5-3(e).
Registration, Fees, and Eligibility Mechanics
Before you ever see a Pearson VUE testing appointment, the Wyoming Department of Fire Prevention and Electrical Safety's State Electrical Board has to approve your application. State approval always precedes ICC/Pearson VUE scheduling - you can't just register on your own timeline the way you might for some national credentials.
Standard eligibility for the master exam requires:
- Eight years (16,000 hours) of electrical experience total
- At least four of those years (8,000 hours) as a licensed journeyman
- 576 hours of approved classroom instruction
- Documented residential, commercial, and industrial work verified through employer and license records
There's also an alternative path: ten years (20,000 hours) as a licensed journeyman or master, combined with Chief Electrical Inspector approval, can substitute for the classroom hour requirement. This matters for experienced tradespeople who never went through a formal apprenticeship classroom track. For the complete eligibility breakdown, including how the verification paperwork works, see WY-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.
On cost: the exam fee is $115, the initial master license runs $200, and renewal is $100 every third year. That's before any prep materials, reference books, or classroom hours you might still need. A full cost breakdown - including what candidates commonly underestimate - is in WY-ME Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Start your state application well before you plan to test. State Electrical Board approval is a prerequisite step, not a formality you can skip by scheduling directly with Pearson VUE.
One more mechanical detail that trips people up: a working master license only lets you practice while employed by a current Wyoming electrical contractor. The individual master license is not itself a contractor license, so passing the exam is one step in a larger licensing chain, not the finish line.
Domain-by-Domain Breakdown
The WY-ME exam covers nine content domains, and they are not weighted evenly. Three domains together account for 51% of the exam, meaning your study hours should be allocated the same way your risk of missing points is allocated - not evenly across nine topics.
| 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% |
For a question-by-question sense of what each domain actually tests - not just the percentage - read WY-ME Exam Domains 2026: Complete Guide to All 9 Content Areas. Below is a quick tactical view of the three heaviest domains.
Wiring Methods and Materials (19%)
The single largest domain. Expect questions on conductor types, raceway fill, box sizing, support and securing requirements, and selecting the correct wiring method for the occupancy and environment.
- Practice raceway and box fill calculations until they're automatic
- Know which wiring methods are permitted vs. prohibited in specific locations
Services and Service Equipment (16%)
Service sizing, disconnect requirements, grounding and bonding at the service, and clearance rules show up repeatedly here.
- Be fluent in service load calculations, not just formulas but table lookups
- Review grounding electrode system requirements carefully
Branch Circuits and Conductors (16%)
Conductor ampacity, derating, overcurrent protection coordination, and branch circuit load calculations dominate this domain.
- Practice ampacity derating for multiple conductors in a raceway
- Understand continuous vs. noncontinuous load rules for circuit sizing
Reference Materials and What You Can Bring
Because WY-ME is open-book, your reference strategy is almost as important as your code knowledge. ICC's reference rules for this exam permit the listed NEC, Ugly's Electrical References, the NEC Handbook, Ferm's Fast Finder Index, and Tom Henry's Key Word Index, subject to ICC's standard reference rules.
A few rules candidates frequently overlook:
- References must be bound - loose pages or unbound printouts are not allowed
- Pre-existing ink notes, highlighting, and permanent tabs in your books are fine
- Writing in your references during the exam itself is prohibited
- You'll need a basic battery-operated, nonprogrammable, nonprinting calculator
- Valid government-issued photo ID matching your exam record is required at check-in
This is also where the NEC edition question becomes critical. An August 19, 2025 ICC bulletin specifies NEC 2023 for this exam, but Wyoming adopted NEC 2026 for installations effective July 1, 2026. Those are two different things - the installation code edition and the exam's assigned reference edition don't automatically move together. Confirm the exact edition assigned to your scheduled exam before you buy or tab a code book; studying the wrong edition wastes weeks of prep time on section numbers and table layouts that won't match your test.
Key Takeaway
Tab your NEC by domain before you start studying, not the week of your exam. A well-organized, pre-tabbed code book is often the difference between finishing all 100 questions and running out of time.
A Realistic Study Timeline
Generic study techniques only matter if they're mapped to WY-ME's actual weighting. Here's a six-week structure built around the domain percentages rather than an even split across nine topics.
Wiring Methods and Materials
- Review raceway types, fill calculations, and box sizing
- Drill permitted wiring methods by occupancy type
Services and Service Equipment
- Practice service load calculations and grounding electrode rules
- Time yourself locating relevant tables in your bound NEC
Branch Circuits and Conductors
- Work through ampacity derating and overcurrent protection scenarios
- Review continuous load and voltage drop considerations
General Knowledge and Special Occupancies
- Cover code organization, definitions, and administrative requirements
- Study hazardous locations, health care facilities, and other special occupancy rules
Equipment and Devices, Motors and Generators
- Review overcurrent protection for motors and disconnect sizing
- Study equipment grounding and device-specific installation rules
Feeders, Control Devices, and Full Timed Practice
- Close out the smaller domains quickly
- Run full-length, timed practice sessions under exam-day conditions
Run timed practice questions at wymeexam.com throughout this window so your pacing matches what you'll face on test day, not just your content knowledge. If you want a condensed version of every must-know fact for a final review pass, the WY-ME Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for exactly that.
Exam Day Logistics
Arrive with your bound reference materials, your approved calculator, and valid government-issued photo ID that matches your Pearson VUE exam record exactly - name mismatches are a common and avoidable reason for turned-away candidates. Double-check your scheduled exam window and location ahead of time; scheduling specifics and how far in advance you should book are covered in WY-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
With 5 hours for 100 questions, build in a pacing checkpoint: if you're not roughly halfway through the exam by the halfway point of your time, you're behind. Since this is open-book, resist the urge to verify answers you're already confident about - save book lookups for genuinely uncertain calculations, especially in the heavily weighted domains.
After the Exam: Pass, Fail, and Renewal
If you don't pass on the first attempt, Wyoming requires a ten-day wait before you can retest. Use that window productively - review which domains cost you the most points rather than restarting your prep from scratch. If you're unsure how common first-attempt passes are or want to calibrate expectations, see WY-ME Pass Rate 2026: What the Data Shows.
Once licensed, master licenses renew every third year by July 1. Renewal requires 16 approved continuing-education hours, including at least 8 NEC-specific hours earned during that license period. There's a grace period through August 15 for late renewal, which carries a $50 late fee - miss that window entirely and you'll need to re-examine rather than simply pay a fee.

Frequently Asked Questions
The exam has 100 multiple-choice questions with four answer options each, and you're given 5 hours to complete it. It's computer-based and administered through Pearson VUE.
Wyoming rule 041-5, section 5-3(e) requires a 75% passing grade for master applicants, meaning at least 75 correct answers out of 100.
Yes, as long as it's bound and it matches the permitted reference list, which includes the listed NEC, Ugly's Electrical References, the NEC Handbook, Ferm's Fast Finder Index, and Tom Henry's Key Word Index. Pre-existing highlighting, ink notes, and permanent tabs are allowed, but you cannot write in your references during the exam.
An August 19, 2025 ICC bulletin specifies NEC 2023 for this exam, while Wyoming's installation code moves to NEC 2026 on July 1, 2026. Confirm the exact edition assigned to your scheduled exam before purchasing code-specific study materials, since the two dates don't necessarily align.
You must wait ten days before you're eligible to retest. Use that time to review the domains where you lost the most points, particularly Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits and Conductors, which together make up 51% of the exam.
