A good electrical practice-test score is consistently above your exam’s passing mark on questions you have not memorized, completed within the time limit. Check the passing score and format for your license through your state’s exam requirements. Use practice results to choose what to study next.

What score passes JCR’s 25-question practice test?
JCR’s free quiz marks 18 correct answers out of 25 as passing. That is 72%. Each question is worth four percentage points, so 17 correct is 68% and 18 is the first whole-question score above 70%.
| Correct answers | Score | Questions to review |
|---|---|---|
| 17 of 25 | 68% | 8 missed |
| 18 of 25 | 72% | 7 missed |
| 20 of 25 | 80% | 5 missed |
| 23 of 25 | 92% | 2 missed |
Review correct guesses and slow answers too. A short quiz can identify useful practice topics, but it cannot cover every subject or reproduce the length of your licensing exam.
Three checks matter more than one high score
- New questions: can you apply the rule when the numbers or wording change?
- Timing: can you finish a representative practice set within your exam’s time limit?
- Coverage: are your results strong across the tested subjects, including any separate law or calculation section?
A 100% score after repeating the same questions shows you remember those answers. To check readiness, use different questions and explain the code rule or calculation without relying on the answer key.

Check your exam’s code edition and state-specific requirements before choosing materials.
What should you do after a low practice score?
Choose the two topics that caused the most trouble. Review the matching manual sections or video lessons, work the examples yourself and answer another set on those topics. Then return to mixed practice.
Keep your scores and completion times together. A better score with faster, accurate lookups is useful progress. If errors persist, bring the actual problems and your work to an instructor.
Is 70% the passing score for every electrical exam?
No single passing rule applies to every licensing exam. For example, North Carolina requires 70%, while Washington requires at least 70% in each section. Check whether your exam uses one overall score or separate passing requirements.
Does passing a practice test mean you are ready?
It is one useful check. Before test day, complete fresh mixed questions, a full-length timed practice set and a review of your weakest subjects. Use the same code edition and permitted references your actual exam requires.
