Best Electrician Exam Prep: What Actually Works
Not all prep is built the same. Most of what is out there is a generic question bank with no state specificity, no walkthroughs, and no way to tell you where your time is going. This page covers what to look for before you pay for anything.

The best electrician exam prep is state-specific, shows step-by-step NEC reasoning on every question, and diagnoses your weak spots before test day. Generic question banks fail on all three counts, and that gap is exactly why candidates who study for weeks still walk out of the exam surprised.
Why state-specific questions matter
The Texas TDLR Journeyman exam, the California DIR General Electrician exam, and the Washington L&I exam all pull from the NEC, but they do not weight topics the same way. Texas puts heavy emphasis on branch circuits and overcurrent protection. California adds state amendments that change grounding rules in ways the base NEC does not. Washington runs two separate exam sections, one for general electrical theory and one for code application, each graded independently.
A generic prep bank gives you an average of all of that. A state-specific bank is built to the actual exam outline for your license. See how the outlines compare for Texas TDLR, California DIR, Michigan LARA, Washington L&I, and Maryland.
Step-by-step walkthroughs on every question
A correct answer with no explanation teaches you nothing about the next question. The real exam uses trap answers built from adjacent NEC articles. The question on grounding electrode conductors, for example, trips candidates who confuse Table 250.66 (which sizes the grounding electrode conductor off the service conductors) with Table 250.122 (which sizes the equipment grounding conductor off the overcurrent device). Both tables exist. The exam knows you will mix them up.
Every approved question in JourneymanIQ has a written walkthrough that names the controlling NEC article, explains each wrong answer individually, and gives a job-site memory hook so the rule sticks in the field, not just in a practice session. The walkthrough is the product. The question is just the delivery mechanism.
The weak-spot diagnostic is the starting point, not a bonus
Most candidates who walk into the exam having studied for weeks still lose points in the same two or three NEC sections. They studied, but they studied the things they were comfortable with. The sections they were shaky on never got enough repetitions because no one told them to prioritize them.
The JourneymanIQ diagnostic is 15 questions, about 15 minutes, free, and no signup required. It covers every major exam domain and scores each one separately. You walk out knowing your three weakest NEC sections in priority order, so the next study session goes to the right place instead of the familiar one.
What the two paid plans include
The free diagnostic and sample question banks are available without an account. When you are ready to drill seriously, two plans are available. See pricing for the current breakdown.
Pro ($49) gives you the full state-specific question bank, adaptive drills that re-target your weak sections after every session, and every walkthrough. Pro+ ($129) adds a 3-month window, a 30-day study roadmap built around your diagnostic results, and priority access to new content as states are added.
Neither plan promises you will pass. What they deliver is a structured way to find the NEC sections costing you the most points, drill them in order, and track whether they are actually improving. That is the part most prep tools skip.
The five states JourneymanIQ covers
Full paid question banks exist for five states. Each bank is built to that state exam outline, not adapted from a generic template.
Texas TDLR Journeyman Electrician: closed-book, 85 questions, 75% to pass. Heavy on branch circuits, overcurrent protection, and wiring methods under 2020 NEC.
California DIR General Electrician: open-book, 100 questions, 70% to pass. Includes California state amendments that affect grounding and bonding requirements beyond base NEC.
Michigan LARA Journeyman Electrician: open-book, 80 questions, 2023 NEC. Michigan adopted 2023 NEC earlier than most states, so the question bank reflects the updated articles.
Washington L&I 01 Journeyman: open-book, two sections graded separately under 2020 NEC. General electrical theory in one section, code application in the other. Both must pass on the same sitting.
Maryland Journeyperson (70 questions) and Master (90 questions): open-book, 2020 NEC. The Master exam adds transformer calculations, generator sizing, and feeder design questions that do not appear on the Journeyperson exam.
