Direct Answer
The IBEW aptitude test and the NJATC aptitude test are the same exam. NJATC (National Joint Apprenticeship and Training Committee) is the organization that develops the test for IBEW locals nationwide — it renamed itself the electrical training ALLIANCE in 2014, so all three names refer to one test. Searching any of them leads to the same preparation.
IBEW vs NJATC Aptitude Test
Two names, one test. Here’s the full breakdown of how IBEW, NJATC, and GAN HR relate — and what that means for your preparation.
What Is NJATC?
NJATC stands for National Joint Apprenticeship and Training Committee. It is the joint training body established by IBEW (the union representing electricians) and NECA (the electrical contractors association). NJATC develops the apprenticeship curriculum, sets training standards, and for most locals, administers the aptitude test that screens entry-level applicants.
When you apply to an IBEW local, you are applying to an IBEW-NECA Joint Apprenticeship and Training Committee (JATC). NJATC is the national body that supports all local JATCs. The aptitude test is an NJATC-designed exam, which is why it is sometimes called the “NJATC aptitude test” even though it is used for IBEW apprenticeships.
NJATC Is Now the electrical training ALLIANCE
In 2014 the NJATC announced it was becoming the electrical training ALLIANCE — a change the U.S. Department of Labor formally recognized in Bulletin 2015-20. Announcing the change, then-IBEW International President Edwin Hill put it this way:
“Our training is our foremost marketing tool and the Electrical Training Alliance conveys what we do, the cooperative nature of our program.”
A decade later, most applicants (and most locals’ websites) still say “NJATC test,” so you’ll see both names used interchangeably. Individual locals confirm the arrangement — IBEW Local 81’s aptitude test page states: “The aptitude test is developed and scored under the standards of the Electrical Training Alliance.”
IBEW vs NJATC vs GAN HR: What’s the Difference?
| Term | What It Is | Role in Testing |
|---|---|---|
| IBEW | International Brotherhood of Electrical Workers — the union | Membership destination; sets local-level score thresholds |
| NJATC | National Joint Apprenticeship and Training Committee | Develops and administers the aptitude test for most IBEW locals |
| GAN HR | GAN Human Resources Associates — private testing company | Administers its own six-section battery for 50+ union apprenticeship programs, including some IBEW locals |
| JATC | Local Joint Apprenticeship and Training Committee | The local office where you apply — uses NJATC or GAN HR for testing |
Which Test Will You Actually Take?
If your local tests through the electrical training ALLIANCE (most do), the format is two sections — confirmed by the published test overviews at the Chattanooga JATC, Raleigh-Durham JATC, and Waterloo/Mason City (Local 288) JATC:
Section 1: Algebra & Functions
33 questions — algebra, fractions, decimals, ratios, number patterns
46 minutes
Section 2: Reading Comprehension
36 questions — four technical passages
51 minutes
If your local tests through GAN HR instead, you’re preparing for a different exam: a six-section battery covering reading comprehension, numerical computation, numerical reasoning (number series), problem solving, paper folding, and Bennett-style mechanical comprehension — no calculator, roughly two hours. Our free GAN practice test and GAN study guide cover that format. When in doubt, ask your JATC which administrator they use before you spend weeks preparing.

Frequently Asked Questions
Is the IBEW aptitude test the same as the NJATC aptitude test?
Yes — they are the same exam. NJATC (National Joint Apprenticeship and Training Committee) is the organization that develops and administers the aptitude test on behalf of IBEW locals. When people search for "IBEW aptitude test" or "NJATC aptitude test," they are referring to the same entrance exam.
What does NJATC stand for?
NJATC stands for National Joint Apprenticeship and Training Committee. It is a joint training organization established by IBEW (International Brotherhood of Electrical Workers) and NECA (National Electrical Contractors Association) to develop and administer the electrician apprenticeship entrance exam and training curriculum. In 2014 the NJATC renamed itself the electrical training ALLIANCE — the same organization, and the same test.
Who administers the IBEW aptitude test?
It depends on the local. Most use the electrical training ALLIANCE (NJATC) test: two sections — algebra/functions (33 questions, 46 minutes) and reading comprehension (36 questions, 51 minutes) — scored on a 1–9 scale. Some locals instead contract GAN Human Resources Associates, whose six-section battery is a different exam.
What is the difference between GAN HR and NJATC?
GAN HR (GAN Human Resources Associates) is a third-party testing company that administers aptitude testing for 50+ union apprenticeship programs, including some IBEW locals. Its battery is a DIFFERENT exam from the NJATC/Alliance test: six sections — reading comprehension, numerical computation, numerical reasoning (number series), problem solving, paper folding, and mechanical comprehension. Your local determines which test you take, so confirm with your JATC before you prepare.
How is the IBEW/NJATC test scored?
The test is scored on a 1–9 scale. A score of 4 or higher is typically required to qualify for an interview. Scores of 6–9 are competitive. The math section (algebra and arithmetic) is weighted heavily and is where most applicants struggle.
