Everything you need to know before you start studying.
Exam Facts
What the Exam Tests
Algebra
~22 of 33 math questionsBasic algebra at the Algebra 1 level. No calculator allowed. Covers order of operations (PEMDAS), positive and negative numbers, fractions, decimals, percentages, solving single-variable equations, and substitution. Not geometry, not trigonometry, not calculus.
Number Series
~11 of 33 math questionsPattern recognition — identify the next number in a sequence. Patterns include simple addition/subtraction, multiplication, alternating operations, nested patterns, and multi-rule series. Community-reported as the hardest section because it requires pattern recognition rather than formula application.
Reading Comprehension
36 questionsRead passages on general topics (science, history, social issues — NOT electrical) and answer questions about main idea, detail recall, inference, author's purpose, and vocabulary in context. Passages are 200-400 words at roughly 9th-12th grade reading level.
Common Reasons Candidates Fail
1. Running out of time on the math section
You have 46 minutes for 33 math questions — about 84 seconds each with no calculator. Candidates who get stuck on a hard number series problem and spend 3-4 minutes on it lose time for easier questions they could have answered correctly.
2. Underestimating number series difficulty
Number series questions look simple but can involve nested patterns, alternating operations, or sequences within sequences. Candidates who haven't specifically practiced pattern recognition get stuck. The key is recognizing the RULE, not guessing the next number.
3. Neglecting reading comprehension
Many candidates focus all their prep on math and barely practice reading comprehension. But it's 36 of 69 questions — over half the test. Candidates who struggle with identifying the main idea or making inferences lose significant points.

▶What is on the IBEW apprenticeship aptitude test?
The IBEW aptitude test has 69 questions in two sections: Algebra & Number Series (33 questions in 46 minutes, no calculator) and Reading Comprehension (36 questions in 51 minutes). The math covers basic algebra and pattern recognition. The reading section uses general-topic passages.
▶What score do you need to pass the IBEW aptitude test?
There is no fixed passing score — candidates are ranked on a scale of 1 to 9. A score of 4 or higher typically qualifies you for an interview, but competitive locals may require a 6 or higher. The score is combined with your interview performance.
▶What happens if you fail the IBEW aptitude test?
If you don't score high enough, you must wait 6 months before retesting. This lockout applies to the same local JATC — some locals allow earlier testing if you apply to a different local.
