- Passing requires 75% on 100 questions in 5 hours per Wyoming rule 041-5, section 5-3(e).
- Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits together equal 51% of the exam.
- Exam fee is $115; initial master license is $200; renewal is $100 every third year.

Exam Snapshot: Numbers You Must Know
The Wyoming Master Electrician License Exam (WY-ME) is a computer-based, open-book, multiple-choice test administered through Pearson VUE on behalf of the Wyoming Department of Fire Prevention and Electrical Safety, State Electrical Board. It uses the ICC Contractor/Trades examination 701 Wyoming Master Electrician exam. Before you touch a single practice question, memorize these numbers cold - they show up in scheduling logistics, pacing decisions, and even how you allocate study time.
- Question count: 100 multiple-choice questions, four options each
- Time allowed: 5 hours
- Format: Open-book, computer-based
- Passing score: 75%, per Wyoming rule 041-5, section 5-3(e)
- Retake wait: 10 days after a failed attempt
Five hours for 100 questions sounds generous, but open-book exams eat time when you're flipping through Ugly's or the NEC Handbook for every reference-heavy question. If you want a deeper breakdown of why this format trips people up, see How Hard Is the WY-ME Exam? Complete Difficulty Guide 2026.

Fees, Licensing Costs & Renewal Math
Money mistakes are avoidable mistakes. Here's every dollar figure tied to the WY-ME pathway, laid out plainly so you're not surprised at the Pearson VUE registration screen or the license portal.
| Item | Cost | When It's Due |
|---|---|---|
| ICC/Pearson VUE exam fee | $115 | At exam registration |
| Initial master license | $200 | After passing, upon licensure |
| Renewal (every 3rd year by July 1) | $100 | Standard renewal cycle |
| Late renewal fee | $50 | Renewals filed after July 1, through August 15 |
Note that missing the August 15 grace-period cutoff doesn't just cost you $50 - it forces re-examination entirely. That's a much bigger expense than the late fee itself once you factor in the $115 exam fee again. For a full walkthrough of every cost bucket, including how these figures stack against total pathway spend, check WY-ME Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Budget for $115 (exam) + $200 (initial license) minimum before you're legally practicing as a master. Renewal is a recurring $100 every three years, contingent on 16 CE hours including at least 8 NEC hours.
Domain Cheat Sheet: Weight by Content Area
The WY-ME exam draws from nine domains, and they are not weighted evenly. Three domains alone make up just over half the test. If your study time isn't proportional to these weights, you're studying wrong.
Domain 5: Wiring Methods and Materials - 19%
The single heaviest domain. Covers cable and raceway types, conductor sizing and protection, box and conduit fill, and installation methods across residential, commercial, and industrial settings.
- Know fill calculations by heart - these are calculator-friendly but rule-heavy
Domain 2: Services and Service Equipment - 16%
Service entrance conductors, disconnecting means, grounding and bonding at the service, and equipment ratings. Expect scenario-based questions referencing specific NEC tables.
- Practice locating grounding electrode and bonding jumper rules quickly in your reference
Domain 4: Branch Circuits and Conductors - 16%
Circuit loading, conductor ampacity, overcurrent protection coordination, and multiwire branch circuit rules.
- Ampacity correction and adjustment factors are a recurring theme
Together, Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits and Conductors account for 51% of the exam. The remaining six domains - General Knowledge (12%), Motors and Generators (8%), Special Occupancies, Equipment, and Conditions (12%), Equipment and Devices (10%), Feeders (4%), and Control Devices (3%) - round out the rest. For a domain-by-domain breakdown with study angles for each, see WY-ME Exam Domains 2026: Complete Guide to All 9 Content Areas.
What You Can (and Can't) Bring to the Exam
Because WY-ME is open-book, your reference materials are part of your test-taking toolkit - but ICC reference rules are specific about format.
- Permitted: the listed NEC, Ugly's Electrical References, NEC Handbook, Ferm's Fast Finder Index, and Tom Henry's Key Word Index
- Binding requirement: all references must be bound - loose pages are not allowed
- Pre-existing markup: ink notes, highlighting, and permanent tabs made before exam day are allowed
- Prohibited during the exam: writing in your references while testing
- Calculator: basic battery-operated, nonprogrammable, nonprinting only
- Identification: valid government-issued photo ID matching your exam record exactly
Key Takeaway
Tab and highlight your NEC and Ugly's before test day - you cannot add markup once the exam starts. Build your tabbing system around the 51% domains first.
Eligibility Shortcuts to Memorize
Before you can even schedule with Pearson VUE, Wyoming requires state approval. This isn't a formality - it's a documented, hour-tracked process.
- Standard path: 8 years / 16,000 hours of electrical experience, including 4 years / 8,000 hours as a licensed journeyman
- Classroom requirement: 576 hours of approved classroom instruction
- Alternative path: 10 years / 20,000 hours as a licensed journeyman or master, with Chief Electrical Inspector approval in place of classroom hours
- Documentation: employer and license verifications covering residential, commercial, and industrial work
Remember, too, that a working master must be employed by a current Wyoming electrical contractor - the individual master license is not itself a contractor license. That distinction matters for anyone planning to run their own shop. Full detail on documentation and both eligibility tracks is covered in WY-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.
NEC Edition Confusion for 2026
This is the single most common mistake candidates make heading into 2026: buying the wrong code book. The August 19, 2025 ICC bulletin specifies the exam is based on NEC 2023. But Wyoming separately adopted NEC 2026 for actual field installations, effective July 1, 2026. These are two different things - the edition tested and the edition enforced in the field can diverge during a transition window.
Action item: confirm your assigned exam edition directly with the ICC bulletin or your registration paperwork before purchasing code-specific study materials. Don't assume, and don't buy based on installation-date adoption alone.
Key Takeaway
Verify your exact NEC edition assignment before spending money on code books. Field adoption dates and exam edition dates are not automatically the same.
Final-Week Review Schedule
If you've already built your months-long prep (covered step-by-step in WY-ME Study Guide 2026: How to Pass on Your First Attempt), the final stretch should shift from learning to reinforcement and reference-navigation speed.
Heavy Domains First
- Drill Wiring Methods and Materials, Services and Service Equipment, and Branch Circuits and Conductors - the 51% block
- Time yourself locating tables in your bound NEC
Mid-Weight Domains
- Cover General Knowledge, Equipment and Devices, and Special Occupancies, Equipment, and Conditions
- Review grounding and bonding scenarios specific to services
Lighter Domains + Full Simulation
- Finish Motors and Generators, Feeders, and Control Devices
- Run a full 100-question, 5-hour timed simulation
This isn't a generic study calendar - it's built around the exact domain weights above, so your heaviest review time lands on the content that determines the majority of your score.
Retest and Renewal Rules
A few procedural facts that catch candidates off guard after the exam is over:
- Failed the exam? You must wait 10 days before retesting - plan your next attempt accordingly rather than assuming same-week retakes.
- Master licenses renew every third year by July 1.
- Renewal requires 16 approved continuing-education hours, including at least 8 NEC hours, earned during the license period.
- Renew late (after July 1 but by August 15) and pay a $50 late fee; miss August 15 entirely and you're back to re-examination.
