How to take the test
Knowing the code is half of it. The other half is getting through the book and the clock. These tips work for any state and any NEC edition.
See the book, tab, and calculator rules from the official PSI bulletin, plus the journeyman exam format.
Before test day
- 1
Find your candidate bulletin and read it first
The candidate bulletin is the rulebook your testing company publishes for your license exam. It says which NEC edition is tested, which book bindings and tabs are allowed, which calculators you can bring, what ID you need, and how long each part of the test runs. Your state licensing board's exam page links to it. Read it before you buy a book, tabs, or a calculator, so nothing gets turned away at the door.

Study the edition you'll be tested on
Section and table numbers move between editions. Confirm which NEC edition your exam uses, study from that book, and set the same edition in Code Compass so every answer cites the right numbers.
- 3
Use only the tabs your bulletin allows
Some exams accept only the permanent index tabs made by the NEC publisher, and make you pull homemade tabs before you can test. Check the rule, then tab every chapter plus the articles you use most.

Highlight at home, with gel highlighters
Do all your highlighting before exam day; most bulletins ban marking the book during the test. Use gel highlighters. Liquid ones can bleed through the thin NEC pages and blot out the text on the back. Highlight the headers and column titles of the tables you reach for most, so your eyes land on the right column without scanning.
- 5
Bring a battery-powered calculator, not solar
Most exams allow only a silent, battery-operated, non-programmable calculator, and a solar-only model can fade under dim testing-room lights. Buy one that matches your bulletin and work every practice problem on it, so the keys are second nature.

Carry a backup, if your bulletin allows it
You can't leave the testing room to fix a dead calculator. If your bulletin allows it, bring a second approved calculator or spare batteries. If the bulletin doesn't say, ask the testing company before exam day.

Translate slang into code words
The code book uses code terms, not job-site names. Turn the slang into the code term before you start looking.
Romex → Type NM cable · Greenfield → flexible metal conduit (FMC) · Sealtite → liquidtight flexible metal conduit (LFMC)

Run The 5-Step Method, and keep the index as backup
Pick the keyword, then decide whether it's General, Plan, Build, or Use, and go to that chapter's table of contents. If you're still stuck after about 30 seconds, look the keyword up in the index instead.
- 9
Read the last sentence first
Long word problems hide the question at the end. Read the final sentence to see exactly what they want, then go back and pull out only the numbers you need.
- 10
Watch the small words
One word can flip the answer. Circle in your head words like NOT, EXCEPT, minimum, maximum, and permitted versus required before you choose.
- 11
Work in passes, not in order
First pass: answer everything you know or can find fast. Second pass: single-step math. Last pass: the long calculations. If your exam is split into timed sections, use the passes inside each section.
- 12
Use a 60-second limit
If you've spent about a minute on one question and you're still flipping pages, flag it and move on. One hard question shouldn't cost you three easy ones. Come back to it on your next pass.
- 13
Don't leave blanks
Check your bulletin, but on most licensing exams a blank and a wrong answer score the same. Before time runs out, make your best pick on every flagged question.
Put it into practice
Run the method on a real question with Sentinel Volt (your first question is free), or practice against the clock with a timed test.
These are study strategies, not a guarantee of any result. Your candidate bulletin's rules always come first.
