Washington Journeyman Electrician Study Guide (2026)

What the exam tests

The Washington General Journey Level Electrician (01) exam is administered by PSI Services for the Washington State Department of Labor & Industries (L&I). It is not one test. It is two scored sections. 70% on each section separately. You retake only the section you fail.

• NEC & Theory: 60 questions in 3 hours. Code rules, theory, and calculations, all against the 2020 NEC. That works out to about three minutes a question, which is tight for an open-book test if you have to hunt for every answer.
• Washington Laws & Rules (RCW 19.28 + WAC 296-46B): 17 questions in 1 hour. Washington-specific law and rule. Licensing scopes, permits and inspection, supervision, and renewal. None of it is in the NEC. Read the full breakdown on the laws and rules page.

The trap is the second section. Roughly 22% of the scored questions are Washington law and rule, and that section is its own 70% gate. You can be sharp on the code and still fail the exam because you never opened RCW 19.28 or WAC 296-46B. The full two-section structure is on the exam format page.

What to bring: the open-book stack

Washington is open book and you bring your own references. Per L&I, the allowed materials are:

• National Electrical Code, 2020 Edition
• Washington electrical laws (RCW 19.28) and rules (WAC 296-46B), printed and in a binder
• Any original copyrighted material, including question-and-answer books such as Ugly's or a fast-finder
• A silent, non-printing, non-programmable calculator

Open book, bring your own. Permanent highlighting, underlining, and permanent index tabs are allowed. Handwritten notes, sticky or removable tabs, and writing in the book are not allowed and are treated as a cheating attempt. Set your books up early and study from the exact stack you will carry in. The open-book rules page covers the tab and highlighting details.

A 30-day allocation

This assumes 60 to 90 minutes a day. If your diagnostic shows one section is far weaker, shift days toward it. The plan works both sections because both sections have to clear 70% on their own.

Days 1-7: codebook and binder speed

An open-book exam rewards lookup speed more than memory. Practice landing on Article 250, Table 310.16, and the Chapter 9 tables in your 2020 NEC in seconds, not minutes. Do the same drill in your printed RCW 19.28 and WAC 296-46B binder. Add permanent tabs now, since that is what the rules allow. The codebook speed page has the full drill.

Days 8-15: calculations

Voltage drop, box fill, conduit fill, motor sizing, and load calculations. Two calculation types a day, plus ten minutes of yesterday’s type as warm-up. By day 15 the setup should be automatic, because at about three minutes a question you do not have time to derive the method from scratch. Work the sets on the calculations practice page.

Days 16-22: Washington laws and rules

Give the law section its own block. It is the material almost nobody studies, and it is scored on its own. Work through licensing scopes, permits and inspection, supervision, and renewal until the binder lookups are fast and the common answers are memorized. This is the week that separates a one-trip candidate from a retake.

Days 23-30: timed mocks and cleanup

Run full timed practice in the real shape: a 60-question code block in 3 hours, then a 17-question law block in 1 hour. Score each section against the 70% bar separately. Fix what you missed between runs. The last two days are light review only. Sleep wins more exams than cramming.

Mistakes that cause retakes

• Studying the 2023 NEC. Washington’s field code is newer than the exam. The test cites the 2020 NEC, so prep to that edition.
• Skipping the law section. 17 questions on RCW 19.28 and WAC 296-46B, passed on its own at 70%. Treating it as an afterthought is the most common way strong electricians fail.
• Illegal book prep. Handwritten notes, sticky or removable tabs, and writing in the book are not allowed and are treated as a cheating attempt. Permanent tabs and highlighting are fine.
• Copied exam dumps. Sites claiming real PSI questions are a legal and accuracy problem, and many quietly test the wrong NEC edition. Use original questions that cite the article or the rule.
• Chasing a pass rate. L&I does not publish pass rates for this exam. Any site quoting one made it up. Measure yourself with timed practice instead.

If it goes wrong: the retake rules

Wait 14 days to retest. After a third failed attempt, wait 3 months between attempts. You retest only the section you failed, and you have one year from approval to pass both sections. The fees to know: a $107.60 application fee to L&I ($41.40 nonrefundable), plus a PSI sitting fee of $75 for the 4-hour exam. If you have already failed, start with the failed-the-exam recovery plan, and if only one section failed, read failed one section because you only retake the section you missed.
