What's Actually on the IBEW Aptitude Test
The whole test, explained plainly. No jargon, and no "as you'll recall from algebra class." If you've been putting off preparing because you don't remember the math, start here.
The IBEW/NJATC apprenticeship aptitude test has exactly two sections. No science, no spatial puzzles, no surprise sections. Knowing the shape of the thing is half the anxiety.
| Section | Questions | Time | Pace |
|---|---|---|---|
| Algebra & Functions | 33 | 46 minutes | ~83 sec/question |
| Reading Comprehension | 36 | 51 minutes | ~85 sec/question |
Section 1: Algebra & Functions (33 questions, 46 minutes)
No calculator. Accept that first. Every question gets done by hand, on paper. The questions stay inside a predictable list of topics:
Order of operations (PEMDAS). Evaluate expressions like 6 + 2 × (5 − 3)² − 6 ÷ 2. The classic trap: multiplication does not automatically come before division. They go left to right, so 12 ÷ 3 × 2 = 8, not 2.
Fractions. Division works by Keep-Change-Flip. Addition needs a common denominator first. If you can resize two fractions to share a bottom number, you can handle every fraction question on the test.
Ratios and proportions. Set up the ratio, cross-multiply, solve. A ratio is just a shrink/grow factor written as a fraction.
Percentages and decimals. "Percent" means "per hundred," so 65% is 0.65. The fast mental method: build answers from 10% chunks instead of multiplying the decimal straight out.
Basic algebra. Solving linear equations, function notation, exponents, and number-series patterns. Find the rule, predict the next term.
Plenty of the math questions are reading questions in disguise. The math is easy; the setup is written like a paragraph. That's why the second section matters more than people expect.
Section 2: Reading Comprehension (36 questions, 51 minutes)
You read a passage, then answer questions about it. Three question types show up:
Direct information retrieval. The answer is stated in the passage, wrapped in trade language (wire colors, equipment names) you already know from the field. Inference. The answer isn't written down; you combine two facts from the passage. Vocabulary in context. What a word means as used in this passage, not its dictionary definition.
The passages lean on electrical trade terms on purpose. Electricians tend to score better here than grammar-school stars, because the content is familiar.
Scoring: the stanine scale, explained simply
Your results come back as a stanine, a score from 1 to 9 that shows how you did against everyone else who tested. It's a ranking band, not a percentage. You don't need to be perfect.
A 4 or higher generally qualifies you for the interview stage. That's the whole bar. Most applicants who prepare at all clear it.
Two scoring facts worth more than any study session:
There's no penalty for guessing. Wrong answers cost nothing. A blank is the only guaranteed zero, so never leave a bubble empty. Section 1 carries the weight. Many JATCs lean on the algebra score when they build their interview list. Check with your local, but plan as if the math section decides everything.
What this means for how you study
Three practical conclusions:
1. Speed beats brilliance. At about 83 seconds a question with no calculator, slow-but-perfect loses to fast-and-mostly-right. Drill until order of operations and fraction moves are automatic.
2. Rusty fundamentals are the whole game. Nobody fails this test on advanced topics. They fail because PEMDAS, fractions, and ratios got shaky after years away. That's fixable in days, not months.
3. Guessing strategy is free points. Flag it, guess, move on, come back if time allows.
