Frequently Asked Questions

How is the Washington Journeyman Electrician exam structured?

The Washington 01 general journey level electrician exam has two separately scored, open-book sections given by PSI: NEC & Theory (60 questions, 3 hours) and Washington Codes on RCW 19.28 and WAC 296-46B (17 questions, 1 hour). That is 77 scored questions in 4 hours, and up to 10 unscored pretest questions may be added.

What happens if I fail one section of the Washington exam?

Within your one-year exam period, which starts on the date of your L&I approval letter, you retake only the section you failed. You must wait 14 days after a failure, and after failing any section three times in a one-year period you must wait 90 days between attempts. If the year ends before you pass every section, you reapply and retake all sections.

What references are permitted during the open-book exam?

You may bring any original copyrighted material, including the NEC (L&I and PSI list the 2020 edition), and printed copies of RCW 19.28 and WAC 296-46B, hole-punched in a three-ring binder. Books may have highlighting, underlining, and permanent tabs only. Photocopies of copyrighted material, internet printouts other than the RCW and WAC, personal notes, and removable tabs are not allowed.

What are the experience prerequisites for the Washington 01 license?

Since July 1, 2023, in-state candidates qualify by completing an 8,000-hour RCW 49.04 electrical construction trade apprenticeship with at least 4,000 hours of new commercial or industrial work and 96 hours of in-class education. Out-of-state routes include an equivalent apprenticeship, a journey level license earned by exam in a state requiring 8,000 hours, 16,000 hours of out-of-state experience, or 8,000 hours in a military construction battalion.

What is the passing score for the Washington exam?

You need at least 70% on each section: 42 of 60 NEC & Theory questions and 12 of 17 Washington Codes questions. A high score on one section cannot make up for a failing score on the other.
