What is the best Washington electrician exam prep?

The best prep trains both Washington sections: NEC and theory on the 2020 NEC, plus the separate Laws and Rules section on RCW 19.28 and WAC 296-46B.

Is Mike Holt enough for the Washington 01 exam?

Mike Holt can help with NEC foundation. It is not enough by itself unless you also train Washington Laws and Rules and the 2020 NEC edition the exam cites.

Why does Washington prep need state-specific content?

Because the exam has a separate 17-question Laws and Rules section, and you must pass it on its own. Generic NEC prep usually skips that section.

Best Washington electrician exam prep, compared

Washington prep must handle two things generic prep often misses: the exam still uses the 2020 NEC, and the Laws and Rules section is scored separately. Here is how the main prep paths compare.

Use this as a fit check, not a scoreboard. The right prep depends on your test date and the section you are missing.

The Washington trap

Washington's field code and exam code do not line up. The exam is still on the 2020 NEC, even though the field code moved forward. On top of that, the Laws and Rules section is its own scored section. A generic NEC course can leave you exposed on about a fifth of the test.

What to check before you pay

2020 NEC for the exam: It should plainly say the exam is based on the 2020 NEC and not train only the newer field code.
Separate law module: It should train RCW 19.28 and WAC 296-46B as a real section, not a footnote.
Two-section pacing: It should rehearse the 60-question NEC section and 17-question law section separately.
Retake logic: It should help you repair the section you failed instead of restarting the whole exam plan.

Best fit by situation

JourneymanIQ

Best fit when you want Washington-specific prep across both sections. The diagnostic shows whether the NEC section or Laws and Rules section is costing you.

Mike Holt

Best fit for broad NEC foundation. Strong for code teaching, but you must add Washington law and 2020 NEC exam-edition practice.

Tom Henry

Best fit for calculation reps. Useful for NEC math, but it does not cover the Washington law section by itself.

Free resources

Best fit for reading L&I rules and learning the outline. Not enough alone if you need timed section repair.
