Washington electrician exam format and how many questions

The two sections

This is the part most candidates get wrong before they walk in. The 01 exam is not one 77-question test you average across. It is two separate tests scored on their own, and you have to clear 70% on each. A strong NEC score does not carry a weak Laws and Rules score, and the reverse is just as true.

• NEC & Theory (60 questions, 3 hours): grounding and bonding, box and conduit fill, voltage drop, motor and feeder sizing, and dwelling load, all referenced to the 2020 NEC.
• Washington Laws & Rules (RCW 19.28 + WAC 296-46B) (17 questions, 1 hour): RCW 19.28 and WAC 296-46B, covering licensing scopes, permits and inspection, supervision ratios, and renewal. This is Washington-specific content you cannot pick up from a generic national prep course.

What you pay and who runs it

Washington State Department of Labor & Industries (L&I) owns the certificate and sets the rules. PSI Services delivers the test at its centers. $107.60 application fee to L&I ($41.40 nonrefundable), plus a PSI sitting fee of $75 for the 4-hour exam. The L&I fee covers your eligibility review, and the PSI fee is what you pay to sit each time, so a retake costs you again at the test center.

Open book, but bring your own

Washington is open book, and unlike states that hand you a clean reference at the desk, you bring your own materials. That is an edge if you set the book up right and a trap if you do not. You may bring the 2020 NEC, your printed RCW 19.28 and WAC 296-46B in a binder, and copyrighted question-and-answer books such as a fast-finder, plus a silent non-programmable calculator.

How hard is it, honestly

L&I does not publish a pass rate for the 01 exam, so anyone quoting you a percentage is guessing. We are not going to invent one. The honest read on difficulty is structural, not a number.

• Two pass bars, not one. You can ace the NEC section and still go home a retake because the Washington Laws and Rules section came in under 70%. Candidates underweight that 17-question section because it is short, and it ends more retakes than they expect.
• Speed under the clock. Open book does not mean slow. You have to land on the right 2020 NEC article or the right RCW or WAC section fast, because looking up every question burns the 3 hours and the 1 hour you are given.
• The open-book trap. The answer is in the room with you, which feels safe and is not. Guys who never drilled the lookup spend the exam flipping pages instead of working problems, and run out of time on the calculations.

That is why a question count alone tells you almost nothing about whether you are ready. The right prep rehearses both sections under time and trains the lookup, not just the rule.
