Pick an electrical exam prep course built for your exam's edition of the National Electrical Code (NEC), with timed practice tests. Your candidate bulletin lists the edition, the number of questions and the time limit. It's the official exam rulebook from your state's testing company, such as PSI or Prov.
| Check this | What a good course gives you |
|---|---|
| Your exam and code edition | The NEC edition your bulletin lists. Find yours on our state requirements page |
| Practice exams | Full-length, timed, open book (you bring approved code books), scored by topic |
| Code navigation | Practice in your own book with permanent tabs, which a PSI bulletin defines as tabs that would tear the page if removed |
| Calculations | Worked load, motor, box fill and conduit fill problems |
| Pass rate | A number with a plain explanation of who it counts |
| Total cost and terms | Course, books and exam fees, with refund and reschedule rules in writing |
Does the electrical exam prep course match your exam's NEC edition?
Check this first. States pick their own code edition, so match your books and course to the edition on your exam. See every state on our electrician license requirements by state page.
The wrong edition teaches section numbers you won't find in your book. See JCR's NEC edition by state and which books to bring.

Do the practice exams match the real test?
- Same length and time limit. NC's Limited, Intermediate and Unlimited exams are 100 questions in 6 hours. Tennessee's Electrical Contractor exam is 100 questions in 5 hours.
- Same book. Practice with the code book you'll bring.
- Useful feedback. Answers that cite the code, and scores by topic.

Will NEC exam prep teach you to find answers fast?
On an open-book exam, speed in the book matters as much as memory. NC's handbook calls its exams "OPEN BOOK," and you bring your own references.
A good course teaches the NEC's layout, index and tabbing. NC's handbook, Tennessee's bulletin and the PSI bulletins JCR checked allow permanent tabs only, so practice with the tabs you'll test with. See NEC tab rules by state and how JCR's tabs work.
Does it cover the calculations on your exam?
NC's handbook lists about 11 load calculation questions on its Limited, Intermediate and Unlimited exams. Look for worked examples of:
- Branch-circuit and total load calculations
- Conductor ampacity and overcurrent device sizing
- Motor circuits
- Box fill and conduit fill
Can you reach an instructor?
Ask who teaches and how fast you get help between lessons. JCR's lead instructor, Victor Ring, has 50+ years in the trade and 10+ years teaching with JCR.
Classroom, live Zoom or self-study: which electrician exam prep fits you?
| Format | Works well when | Trade-offs |
|---|---|---|
| In-person classroom | You want questions answered on the spot | Set dates, travel and time off work |
| Live Zoom class | You want a live instructor but can't travel to a class city | Set class times and steady internet |
| Self-study | Your schedule shifts, or you want the lowest cost | You set the pace, so it takes discipline |
Plan on 6–8 weeks of study, about an hour a night.
How should you judge a pass rate?
- Who's counted? Every buyer, or only class finishers?
- First try or any try? Counting retakes makes a rate look higher.
- Which exam? One license class, or all of them blended?
JCR's figure: a 93% pass rate for JCR classroom students. Statewide, see the NC electrical exam pass rate by year.
What does an electrical exam prep course cost?
- The course, and what materials come with it.
- Code books: your exam's NEC edition plus any other required references, like NC's 2013 NFPA 72.
- Tabs, if the course has none.
- Exam fees: NC charges $125 per attempt for the application and exam.
- Travel and time off for a classroom course.
Failing costs more. In NC, each attempt needs a new approval and fee, and you wait 3 months to retest in that class.
What refund and retake terms should you look for?
- A written refund policy before you pay.
- Class changes if your exam date moves.
- Access time for videos and practice exams.
- A plan if you fail: sit in again, or keep your materials?
