Electrician Exam Practice Test: What to Look for and Where to Start
Most practice tests hand you a score and leave you there. A real-format practice test scores you by NEC topic so you know exactly where to put your study hours before the actual exam.

A good electrician exam practice test matches the real exam format, covers the right NEC articles at the right weight, and scores you by topic, not just overall. The free 15-minute diagnostic on JourneymanIQ does all three, with no signup and no card. Start at journeymaniq.com/diagnostic.
What a real-format practice test must include
The TDLR Texas Journeyman exam, the California DIR General Electrician exam, and the open-book exams in Michigan, Washington, and Maryland all follow the same basic structure: multiple-choice questions, four choices, one correct answer, and a time limit that rewards candidates who know where to look fast. A practice test that does not match that format is not actually preparing you.
The four things a real-format practice test must have:
1. Questions weighted to the state exam outline. The TDLR exam does not split its questions evenly across every NEC article. Wiring methods, overcurrent protection, and grounding carry more weight than, say, swimming pools. A practice test built to the right distribution prepares you for the actual score breakdown, not a generic one.
2. Four answer choices with trap answers. The real exam always includes answers that are correct for a neighboring rule. A grounding question might include an answer that applies Table 250.66 when the right table is 250.122. If your practice test only shows obviously wrong wrong-answers, you are not building the discrimination skill you need on test day.
3. Step-by-step walkthroughs with NEC citations. Every approved question on JourneymanIQ has a walkthrough that explains the controlling rule, cites the article number, and explains why each wrong answer is wrong. NEC 250.122 sizes the equipment grounding conductor off the overcurrent device. NEC 250.66 sizes the grounding electrode conductor off the service conductors. Mixing those two is the single most common grounding miss on the exam, and you only stop making it when someone explains the distinction in plain English.
4. Per-topic scoring, not just a total. A 68 percent tells you nothing actionable. A result that says you scored 90 percent on branch circuits but 45 percent on calculations tells you exactly where to spend your next three study sessions.
Why a diagnostic beats a random quiz
Random practice banks have a structural problem. They ask you the same mix of questions regardless of where you are weak. If you are strong on wiring methods and weak on motor circuits, a random bank still sends you a full spread of wiring questions you already know. You feel productive. You are not closing the gap.
A diagnostic works differently. It samples across every major NEC domain, scores each one separately, and tells you which sections are dragging your total score. Once you know that, you can practice the right topics in the right order. The free 15-minute diagnostic is designed to do exactly that. No signup. No card. Real questions, scored by topic, with a priority list of what to fix.
JourneymanIQ does not promise you will pass. We tell you which NEC sections to focus on, in priority order, based on what the diagnostic revealed. That is the concrete thing we can actually deliver.
State-specific practice tests
Each state exam has its own format, time limit, and NEC edition. A practice test that does not account for those differences is misleading. Here is the breakdown for the five states JourneymanIQ covers:
Texas (TDLR Journeyman). Administered by PSI. The question mix follows the TDLR exam outline. See the Texas electrician exam prep page for outline weights and sample questions.
California (DIR General Electrician). Administered by the Department of Industrial Relations. Questions map to the DIR subject areas. See the California electrician exam prep page for the domain breakdown.
Michigan (LARA Journeyman). Open-book, 2023 NEC. The open-book format changes what you practice for. You need to know where to look, not just what the rule is. See the Michigan electrician exam prep page.
Washington (L&I 01). Two-section exam, open-book, 2020 NEC. Candidates sit for two scored sections on the same day. See the Washington electrician exam prep page.
Maryland (Journeyperson and Master). Journeyperson is 70 questions, Master is 90 questions. Both are open-book on the 2020 NEC. See the Maryland electrician exam prep page.
How to use a practice test the right way
Most candidates open a practice bank, answer 20 questions, see 75 percent, and feel okay. That is the wrong way to use a practice test. Here is what actually moves the needle:
Take the diagnostic first. Get your per-topic scores. Find the two or three sections below 70 percent. Those are your priority sections. Drill those topics specifically, not the whole question bank, until they come up above 80 percent. Then take the diagnostic again. Repeat until every topic is above 75 percent. That is a study loop. Answering random questions is not.
