How to pass the journeyman electrician exam
To pass the journeyman electrician exam, learn where answers live in the NEC so you can find them fast, practice calculations until they're routine, and take full timed practice exams before test day. Most journeyman exams are open book, multiple choice and based on the NEC edition your state has adopted. A passing score is usually 70% or 75%.
The exam rarely tests whether you can memorize the code. It tests whether you can find the right rule, read it correctly and do the math under a time limit. That changes how you should study.
Start with your exam's candidate bulletin
Every licensing board or its testing vendor (common ones are PSI, Pearson VUE, Prometric and ICC) publishes a candidate information bulletin. Read it before anything else. It tells you:
- Which NEC edition the questions are based on. Many states test on the 2023 NEC, some are already on the 2026 edition and a few are on older ones.
- How many questions there are, how long you get and the passing score.
- Which books you can bring, and whether tabs, highlighting and notes are allowed.
- Whether the exam is one test or split into parts. Texas, for example, split its journeyman exam into a code knowledge part and a calculations part in March 2025.
If your study material is written to a different edition than your exam, check the changes for the topics you study. Article numbers and rules move between editions.
Learn how the NEC is organized
Fast lookups win this exam. Knowing the layout of the code book saves more time than memorizing any single rule.
| Part of the NEC | What's in it | Why it matters on the exam |
|---|---|---|
| Article 90 and Article 100 | Purpose, how the code is arranged, definitions | Many questions turn on a defined word like "accessible" or "continuous load" |
| Chapters 1 to 4 | General rules: wiring, protection, methods, equipment | Apply everywhere unless a later chapter changes them |
| Chapters 5 to 7 | Special occupancies, equipment and conditions | Modify Chapters 1 to 4 for places like pools, hazardous locations and health care |
| Chapter 8 | Communications systems | Stands on its own |
| Chapter 9 | Tables: conduit fill, conductor properties | Used constantly in calculations |
| Informative annexes | Examples and extra tables | Annex C conduit fill tables and Annex D load examples save time |
Practice using the index as much as the table of contents. On test day you'll look up words you've never searched for before, and the index is the fastest path.
Know the most-tested articles
Exams vary, but most journeyman tests lean on the same core of the code:
- Article 210 and 215: branch circuits and feeders, GFCI and AFCI rules, required outlets.
- Article 220: load calculations for dwellings and other occupancies.
- Article 230: services, clearances and disconnects.
- Article 240: overcurrent protection, including the small-conductor rule in 240.4(D).
- Article 250: grounding and bonding. Usually the largest single topic. Know Table 250.66 and Table 250.122.
- Articles 300 to 399: wiring methods, cable and raceway rules, support and securing distances.
- Article 310: conductor ampacity, Table 310.16 and the correction and adjustment factors.
- Article 314: box fill and box sizing.
- Article 430: motors, which has its own tables and its own sizing rules.
- Article 450: transformers.
- Articles 500 to 680: hazardous locations, health care, pools and other special occupancies.

Get comfortable with calculations
On many exams, calculations are where people fail. In Texas, fewer candidates passed the calculations part than the code part in fiscal year 2025, according to TDLR's published statistics.
The good news is that journeyman calculations repeat. The same handful of formulas cover most of them: Ohm's law, power, voltage drop, three-phase current, transformer current, continuous loads at 125%, general lighting loads, box fill and motor conductor sizing. Our journeyman exam calculations guide walks through each one with a worked example.
Work each type until you can set it up without thinking, then practice it against the clock.
Use a study plan
A short daily session beats weekend cramming. Here is a plan that fits 20 to 40 minutes a day over eight weeks. Stretch it if your exam is further out.
| Weeks | Focus |
|---|---|
| 1 and 2 | Code book layout, Article 100 definitions, using the index. Answer questions by finding the rule, not guessing. |
| 3 and 4 | Calculations: Ohm's law, power, voltage drop, three-phase and transformer current, continuous loads, box fill. |
| 5 and 6 | Topic drills on your weakest areas, usually grounding and bonding, load calculations and motors. |
| 7 | Full timed practice exams. Review every miss and find the rule you should have used. |
| 8 | Light review of missed questions and the tables you use most. Rest the day before. |
Track your accuracy by topic. A score that stays above your exam's passing score on timed practice tests is the best sign you're ready.
On test day
- Bring the exact code book edition your bulletin allows, plus your ID.
- Answer the questions you know first. Mark long lookups and come back.
- Budget your time. Divide the minutes by the number of questions so you know your pace.
- Read every word of the question. "Minimum" versus "maximum" and "copper" versus "aluminum" change the answer.
- Never leave a question blank unless your exam penalizes guessing. Most don't.
Frequently asked questions
How long should I study for the journeyman electrician exam?
Most people need six to twelve weeks of steady study, about 20 to 40 minutes a day. If you're already strong on calculations and code lookups, less. If it has been years since your classroom training, plan for more.
Is the journeyman electrician exam open book?
Most are. Candidates can usually bring a bound copy of the NEC edition the exam is based on. Rules on tabs and highlighting vary, so check your candidate bulletin.
What score do I need to pass?
Usually 70% or 75%, set by your state or testing vendor. Your candidate bulletin states the exact score.
What happens if I fail?
Most states let you retake the exam after a waiting period and a new fee. Your score report usually shows which areas you missed, which tells you what to study next.
Can I pass using only practice tests?
Practice tests are the best way to find weak spots and build speed, but the exam rewards knowing where things are in the code book. Use practice questions to find gaps, then go to the NEC to close them.
