- 110 scored questions split across NEC & Theory (80), WA Codes (20), and Major Load Calculations (10).
- Score at least 70% in each of the three sections separately - no averaging across sections.
- PSI exam fee is $105; the separate L&I master application fee is $204.60 under the July 1, 2026 schedule.
- Exam references the 2020 NEC, RCW 19.28, and WAC 296-46B - not necessarily the newest code cycle.
Exam Snapshot at a Glance
If you're days away from sitting the Washington Master Electrician Certificate Exam (WA-ME) and just need the facts without the fluff, this page is built for that. It's the one-pager to skim in the parking lot before you walk into a PSI test center, or to keep open on a second monitor during your last review session. For a slower, more thorough walkthrough of how to prepare, see the WA-ME Study Guide 2026; for a breakdown of what each content area actually covers, see the WA-ME Exam Domains 2026 guide.
The exam is administered by PSI Services LLC on behalf of the Washington State Department of Labor & Industries (L&I). It's the 01-General master electrician examination, computer-based and open-book, made up of 110 scored questions. Up to ten additional unscored experimental questions may also appear, and time spent on those doesn't count against your section clock - so don't panic if a question feels unfamiliar or oddly worded; it may not even be graded.
The Three Timed Sections
Unlike exams that blend all topics into one continuous block, WA-ME splits into three separately timed sections. You must clear each one at 70% or higher - a strong score in one section cannot offset a weak score in another.
Domain 1: NEC & Theory - 80 questions, 240 minutes
This is the largest section by question count and the backbone of the exam. It draws on general electrical theory alongside National Electrical Code application.
- Largest time allotment and largest question count of the three sections
- Requires fluent code navigation, not memorization of article numbers alone
- Weakness here is the most common reason candidates fall short overall
Domain 2: WA Codes - 20 questions, 60 minutes
This section is Washington-specific: state statute and administrative rule rather than national code language.
- Draws directly from RCW 19.28 and WAC 296-46B
- Shortest section, but the pace (20 questions in 60 minutes) leaves little room for hunting through unfamiliar material
- Frequently underestimated because it's the smallest section by question count
Domain 3: Major Load Calculations - 10 questions, 120 minutes
Only 10 questions, but two full hours to work through them - a signal that these problems are computation-heavy, not quick recall items.
- Generous per-question time budget reflects multi-step math
- A silent, nonprinting, nonprogrammable calculator is permitted
- Small question count means each miscalculation carries disproportionate weight toward the 70% threshold
Because each section is timed and scored independently, your prep plan should treat them as three separate mini-exams rather than one long study block. The exam domains guide goes deeper into topic-level breakdowns for each of these three areas, and the WA-ME Passing Score 2026 breakdown explains exactly how the 70%-per-section rule plays out in practice.
| Section | Questions | Time | Passing Threshold |
|---|---|---|---|
| NEC & Theory | 80 | 240 minutes | 70% |
| WA Codes | 20 | 60 minutes | 70% |
| Major Load Calculations | 10 | 120 minutes | 70% |
Fees, Eligibility & Approval Window
Two separate payments are involved, and mixing them up is a common source of confusion. Under the July 1, 2026 fee schedule, the initial PSI examination fee is $105. Separately, L&I charges a master application fee of $204.60, which covers the original certificate and application processing. These are not the same transaction and go to different organizations. A full walkthrough of every cost involved, including renewal pricing, lives in the WA-ME Certification Cost 2026 breakdown.
Eligibility isn't automatic. Candidates need at least four years certified by L&I as a general journey level electrician, followed by L&I exam approval before they can even register for a test date. That approval starts the clock: all three sections must be passed within the one-year approval period. If you pass one or two sections but run out the clock before finishing the third, passed sections do not carry forward beyond that window - you'd need to requalify. Full detail on qualifying pathways is covered in the WA-ME Requirements 2026 guide.
Key Takeaway
Treat your one-year approval period as a hard deadline for all three sections, not just the first attempt. Schedule retakes early enough that a 14-day minimum wait - or a 90-day wait after three failures - doesn't push you past the window.
References & Materials Allowed at the Desk
Because this is an open-book exam, what you're allowed to bring matters as much as what you know. Original copyrighted references and bound printouts of Washington laws and rules are permitted. You're allowed to highlight, underline, and use permanent tabs to speed up navigation during the timed sections. What's not allowed: handwritten notes and removable notes (like sticky flags with writing on them). A silent, nonprinting, nonprogrammable calculator is permitted for the Major Load Calculations section and beyond.
Code Editions You're Actually Tested On
This is one of the most overlooked details among candidates who assume the newest installation code automatically applies. The PSI bulletin dated October 30, 2025 specifies the 2020 NEC, RCW 19.28, and WAC 296-46B as the reference set for this exam. If your jobsite has already transitioned to a newer NEC cycle, that's irrelevant here - bring and study the exam-reference edition specified in the current bulletin, not whatever edition is installed in the field. Always check the current PSI candidate bulletin before your test date in case the referenced edition changes in a future cycle.
WA Codes questions pull specifically from RCW 19.28 (state licensing statute) and WAC 296-46B (administrative rules), so those two references deserve dedicated tabbing and review time separate from your NEC study - they test differently than code-book questions and often hinge on definitions, scope, and procedural requirements rather than installation methods.
Retake Rules and the 90-Day Wall
If you don't clear all three sections on your first sitting, know the retake mechanics before you schedule again:
- A minimum 14-day wait applies between attempts.
- After three failures within a one-year exam period, a 90-day wait applies before your next attempt.
- All sections must ultimately be passed inside your original one-year approval period.
This is why understanding realistic difficulty going in matters - see How Hard Is the WA-ME Exam? Complete Difficulty Guide 2026 for a candid look at where most people lose points, and WA-ME Pass Rate 2026: What the Data Shows for context on outcomes. A single failed section still counts as an attempt against the 14-day/90-day retake structure, so it's worth over-preparing for your first sitting rather than treating it as a low-stakes practice run.
Renewal & Continuing Education Cheat Sheet
Passing the exam isn't the finish line - it's the start of a renewal cycle. Initial certification lasts 25-36 months, after which renewal runs on a three-year birthday-based cycle. To renew, you need 24 approved continuing-education hours, including at least eight code-update hours and four RCW/WAC hours. Renewal costs $175.70 online, or $202.20 if submitted by mail, fax, or in person.
| Item | Detail |
|---|---|
| Initial certification length | 25-36 months |
| Renewal cycle | Three-year, birthday-based |
| Required CE hours | 24 total, including 8 code-update + 4 RCW/WAC |
| Renewal fee (online) | $175.70 |
| Renewal fee (mail/fax/in-person) | $202.20 |
It's worth noting what the certificate does and doesn't authorize: a master electrician may perform installation work and serve as an assigned administrator, but the electrical contracting business license itself is a separate credential. Understanding this distinction matters if you're evaluating career paths - see WA-ME Jobs for how employers in Washington typically use this certification, and Is the WA-ME Certification Worth It?

The Week-Before Checklist
In the final stretch, your study time is better spent matching effort to section weight than spreading evenly across all three areas. Since NEC & Theory carries 80 of the 110 scored questions, it deserves the majority of remaining review time - but don't neglect WA Codes just because it's small; its 60-minute pace punishes hesitation.
NEC & Theory Deep Review
- Drill code navigation speed using your tabbed 2020 NEC
- Work theory problems until formulas are automatic, not looked-up
WA Codes Focus
- Review RCW 19.28 and WAC 296-46B tabs specifically
- Time yourself at roughly 3 minutes per question to simulate the 60-minute limit
Major Load Calculations & Logistics
- Practice multi-step load calculations with your permitted calculator
- Confirm allowed materials: bound references, tabs, no handwritten or removable notes
For a more complete multi-week plan that goes beyond this final stretch, the WA-ME Study Guide 2026 lays out a longer-horizon approach, and you can pressure-test your readiness with timed practice at the main WA-ME practice test platform before committing to a scheduled test date. Running full-length, section-timed practice sets there is one of the few ways to know whether your pacing on all three sections - not just your overall knowledge - is actually exam-ready.
FAQ
Not necessarily on the same day, but all three sections must be passed within your one-year L&I approval period. Passed sections only carry forward within that window.
NEC & Theory, since it's the largest section at 80 of 110 scored questions and the most common source of section failure. Still budget dedicated time for WA Codes and Major Load Calculations, since each section requires its own 70% pass.
No. Handwritten notes and removable notes are prohibited. You can highlight, underline, and use permanent tabs in your original copyrighted references and bound printouts of Washington laws and rules.
After three failures within a one-year exam period, a 90-day wait applies before your next attempt, in addition to the standard 14-day minimum wait between retakes generally.
Not necessarily. The PSI bulletin dated October 30, 2025 specifies the 2020 NEC along with RCW 19.28 and WAC 296-46B. Always confirm the exam-reference edition in the current bulletin rather than assuming the newest installation code applies.
