The IBEW aptitude test is not extremely difficult, but it’s harder than most people expect if they haven’t done algebra in a few years. The math section goes beyond basic arithmetic into algebra concepts like factoring polynomials, the quadratic formula, and function notation. If you finished high school algebra and still remember most of it, you can pass with a couple weeks of review. If math class feels like a distant memory, you’ll need serious preparation.
What the Test Actually Covers
The aptitude test has two sections: algebra/functions and reading comprehension. The math portion carries 33 questions with a 46-minute time limit, which gives you roughly 80 seconds per problem. That’s tight enough to create pressure but not so tight that you’re racing through every question.
The reading comprehension section presents long written passages followed by questions about what you just read. There are no tricks here. You read carefully, you answer questions about the content, and you move on. Most test-takers find this section significantly easier than the math.
How Hard Is the Math?
The math lands squarely at the Algebra 1 level, which sounds manageable until you look at the full topic list. You’ll need to handle fractions, decimals, positive and negative integers, exponents, the distributive property, linear equations, proportions, coordinate plane plotting, and the FOIL method for multiplying binomials. The hardest topics are factoring polynomials, factoring quadratics, the quadratic formula, and function notation.
Here’s what a typical problem looks like: you’re given a formula like A = B + 3(4 – C), told that B equals 5 and C equals 2, and asked to solve for A. Another common format gives you an equation like y = 3(x + 5)(x – 2) and asks you to identify an equivalent version. You’ll also see number pattern questions where you identify the next value in a sequence.
None of this is advanced math. You won’t see calculus, trigonometry, or statistics. But factoring quadratics and working with function notation trip up a lot of people who haven’t touched algebra since high school. The difficulty isn’t in any single concept. It’s that you need to be comfortable with all of them under a time constraint.
How to Prepare
IBEW Local 733 specifically recommends Khan Academy’s Algebra 1 course for anyone who needs to brush up, and that’s genuinely good advice. The free course covers every topic on the test. If you work through it methodically, spending 30 to 60 minutes a day, most people can get test-ready in two to four weeks.
Focus your study time on the areas that tend to cause the most trouble: factoring polynomials, the quadratic formula, solving linear equations using substitution, and function notation. If you can handle those comfortably, the rest of the test (fractions, decimals, exponents, basic order of operations) will feel straightforward by comparison.
For reading comprehension, the best preparation is simply practicing active reading. Read a long article, put it down, and try to answer specific questions about it without looking back. The test passages aren’t technical. They just require you to absorb and recall details from dense text.
What Happens If You Don’t Pass
You must wait a full 90 days before retaking the test. This is strictly enforced by the Electrical Training Alliance, the national organization that administers the exam. If you try to retest before the 90-day window has passed, your score gets thrown out and the clock resets for another 90 days. Repeated attempts to get around this rule can result in permanent disqualification.
The passing score itself isn’t publicly released. Results are reported on a stanine scale (a 1 to 9 ranking that compares your performance to other test-takers), and each local training center sets its own competitive threshold. Scoring higher doesn’t just mean passing. It improves your ranking in the applicant pool, which affects how quickly you get placed into an apprenticeship.
Why People Underestimate It
The most common mistake is walking in without studying because the test is described as “high school level math.” That’s technically accurate, but most adults haven’t solved a quadratic equation in years. The combination of rustiness and time pressure is what catches people off guard. A problem you could solve in three minutes with scratch paper becomes stressful when you have 80 seconds and test anxiety working against you.
The reading section rarely causes failures on its own. When people don’t pass, it’s almost always the math dragging their score down. If you’re going to spend limited study time on one section, spend it on algebra.
The bottom line: if you prepare, the test is very passable. If you don’t, the algebra section is hard enough to knock you out of the running and force a 90-day wait before you can try again. A few weeks of focused review is a small investment for a career path that leads to union wages and benefits.
