If you're chasing an electrical license, you'll sit for at least one, and maybe three, serious exams before you can pull a permit on your own. The electrician exam isn't a single test — it's a ladder of them, each one administered a little differently depending on where you work.
This guide walks through all three tiers — apprentice, journeyman, and master — plus the testing bodies that actually write and proctor most of them (PSI, ICC, NASCLA, and various state boards like TDLR). If you're about to register for an electrical license exam and you want to know what you're walking into, start here.
Electrical licensing in the US is a state-by-state affair, but the structure is remarkably consistent. Most states recognize three levels of electrician, and each has its own test.
There's also a fourth category worth flagging — the electrician certification exam — which isn't always a license, but proves competency. Some employers and unions require a certified electrician test for specialty areas like industrial controls, low-voltage, or solar work.
Before you can legally work with tools on a commercial site, most states and union locals want you in a registered apprenticeship. The apprentice electrician test is the gate.
In the IBEW/JATC world, the aptitude test is administered through NECA's partnership with the JATC and covers algebra, functions, and reading comprehension. It's not an electrical knowledge test — you don't need to know the NEC yet. You need to prove you can do the math and follow written instructions on a job site.
Non-union programs (state-registered, IEC, ABC) run their own versions of the apprentice electrician exam. Content varies, but most include basic arithmetic, simple algebra, and sometimes a short reading section. A few states layer a short electrical concepts screening on top.
Don't underestimate the math. Fractions, decimals, ratios, and basic algebra show up every time. If math is rusty, that's the first thing to shore up — long before you worry about Ohm's Law.
Most apprentice tests run two to three hours, paper or computer-based, and score pass/fail against a fixed cutoff. You'll also interview after — the test isn't the only gate.
After your apprenticeship — typically four to five years of documented hours plus classroom time — you're eligible for the journeyman electrician exam. This is the real licensing test, and it's the one most electricians remember.
It's almost always open-book, meaning you can bring a tabbed NEC (National Electrical Code) into the testing room. That sounds generous until you realize the test is timed and the NEC runs over 900 pages. Knowing where to find things fast matters more than memorizing them.
Content covers grounding and bonding (Article 250), wiring methods (Chapter 3), services and feeders (Articles 220, 230, and 408), motors (Article 430), and a stack of calculation problems using Chapter 9 tables for conduit fill and wire sizing.
Question count and time limit depend on your state and testing provider — typically 80–100 questions over 4 hours, depending on the jurisdiction. Passing scores usually sit around 70–75%.
The master electrician exam is the top tier. Passing the electrician master exam lets you pull permits under your own license, supervise journeymen, and in most states, start an electrical contracting business.
You're usually eligible two years after your journeyman license, though requirements vary. The master test goes deeper than the journeyman exam in two ways: the calculations get harder (full service load calcs, voltage drop across long feeders, short-circuit current), and business and law questions show up — contracts, OSHA, state licensing rules, bid bonds.
Typical format: 80–120 questions, open-book, 4–6 hours. Some states split it into two sessions — one technical, one business/law — and require you to pass both.
Two things. First, the calculations compound — a single question might ask you to size a feeder, apply demand factors, then check voltage drop. Second, the business section rewards people who've actually run jobs. If you've been a working journeyman who stayed hands-on but never looked at a bid sheet, budget extra time for that section.
Most electrician exams aren't written by your state directly. They're developed and administered by a handful of testing organizations. Knowing which one runs your exam tells you what to expect in the testing center.
PSI administers electrical exams in a large share of US states. You'll register through their portal, pick a testing center, and take the exam on their computer system. The interface is clean, the timer is prominent, and you can flag questions to revisit. PSI content is written to NEC standards and tends to lean into calculation questions.
The ICC electrical exam shows up in states that use ICC's certification program for inspectors and some licensed electricians. ICC exams are known for being code-heavy — lots of lookups, less raw calculation. If you're comfortable navigating the NEC by article number, ICC tests feel natural.
The NASCLA electrical exam matters if you want to work across state lines as a contractor. NASCLA accreditation lets you skip the business-and-law portion of licensing in participating states. The exam itself is open-book and covers contracting business practices, not field electrical work — but passing it saves you from taking the equivalent test in every new state.
A few states run their own exams. Texas, for instance, administers through TDLR (Texas Department of Licensing and Regulation). Depending on your state, you might sit for a state-written test rather than a PSI or ICC version. Content is similar — NEC-based, open-book — but the interface and passing score can differ. Check your state board's candidate handbook before you register.
Worth clearing up, because it trips people up. A state electrical license lets you work legally in your jurisdiction. An electrician certification exam (a manufacturer cert for specific equipment, or a NICET cert for low-voltage) proves you know a specialty but isn't a license. Some employers accept certifications in place of a license for limited scopes. Most don't. If your goal is to run jobs, the license comes first.
If you're reading this from north of the border, the path looks similar but uses different names. Each province runs its own certification, with the Red Seal endorsement available for interprovincial mobility. Most of what's in this guide about study habits, code lookups, and calculation practice applies — just swap the NEC for the CEC (Canadian Electrical Code).
Every tier rewards the same study habits, scaled up:
Most of our users work through 500–1,000 practice questions in the weeks before their exam — that's what Dakota Prep was built for. Pick your tier, know your testing body, and put in the hours.
Once you've got the license, the next question is usually what it pays. Some states like California have their own certification process (we have a separate guide for that) — but for the rest of the country, passing the journeyman or master test opens the door to real money and your own jobs.
The electrician exam is hard. It's also beatable. People pass it every week with a normal job, a normal life, and a study plan that fits into evenings. Pick your tier, tab your code book, and drill practice questions. That's the whole recipe.
