Full-length NEC practice tests simulating real exam conditions for electrician licensing.
These NEC practice tests are different from the article-by-article tests in the NEC Code category. Each test here pulls mixed questions from across the entire National Electrical Code — just like your actual licensing exam does. No single topic dominates. You need to be ready for anything.
This mixed format is the best way to prepare in the final weeks before your exam. If you have been drilling individual articles, these tests show you how you perform when the questions jump unpredictably between topics.
All tests are based on NEC 2026 but many states are still testing NEC 2023 — the core rules are the same, and our tests are tagged by edition where questions specifically reference changed articles.
NEC 2020 is the edition several state licensing boards were still testing as of 2026 — some states lag a full cycle or two behind the newest published NEC. If your state board has not confirmed a newer adoption date, these tests match what you will likely see on exam day.
NEC 2023 is the edition most state licensing boards have adopted as of 2026. If you have not confirmed your state's exact edition yet, this is the safest default to study.
NEC 2026 is the newest published edition. Mixed practice tests for this edition are in development and will be added here as state boards begin adopting it.
In the meantime, our NEC Code Practice Tests category is already updated for NEC 2026 changes article by article — a good place to start if your state has adopted the newest edition.
Mixed NEC tests expose your weak spots faster than topic-specific tests. Here is how to use your results:
| Article | Topic | % of Typical Exam |
|---|---|---|
| 100 | Definitions | 5–8% |
| 210 | Branch Circuits | 15–20% |
| 220 | Load Calculations | 10–15% |
| 230 | Services | 5–8% |
| 250 | Grounding & Bonding | 10–15% |
| 300–358 | Wiring Methods | 10–15% |
| 310 | Conductors | 5–10% |
| 430 | Motors | 8–12% |
| Other articles | Various | Remaining % |
You can take them untimed for study, or set your own time goal. A good benchmark: the real exam gives you about 2 minutes per question on average. If a 25-question test takes you over 50 minutes, you need to practice using your NEC index faster.
Consistently scoring 80% or above on mixed practice tests is a good sign you are ready. Do not stop at 70% — the real exam has questions you have not seen before, so aim to be comfortably above the passing line in practice.
