IBEW aptitude test practice and five-minute lessons.
For anyone about to sit the IBEW/ETA aptitude test: timed questions, then number series, algebra and reading, with worked steps.
Number series
79, 68, 57, 46, 35, ?
The gaps are all the same: −11, −11, −11, −11. Subtract 11 once more: 35 − 11 = 24.Then learn it, five minutes at a time.
Number series, algebra and reading, timed the way the real test runs, with worked steps for every answer.

Read lesson 1: Number series: find the rule
You can meet number patterns in Algebra and Functions. The official sample includes a number-pattern question.
A number series gives you a row and asks for the next number. Don’t stare at the numbers. Look at the gaps.
Three to five is plus two. Five to nine is plus four. Then plus eight, then plus sixteen.
The gaps double every time. That is the rule for this series.
3, 5, 9, 17, 33, ?
- 49
- 65
- 66
- 64
Answer: 65. The next gap is 32, so 33 + 32 = 65. 66 is the trap if you just double the last number.

Questions
What’s on the IBEW aptitude test?
Two timed tests, no calculator: Algebra and Functions (33 questions in 46 minutes, number series included) and Reading Comprehension (36 in 51 minutes). Some locals use the GAN instead, so ask yours.
Why do a few points matter?
At ETA locals a qualifying score gets you to the interview; at GAN locals, scores rank applicants directly. If you don’t qualify, you wait at least 90 days to retake, and some locals make you wait longer.
Are you part of the IBEW?
No. We’re not affiliated with IBEW, NECA, the Electrical Training Alliance or any JATC, and every practice question is original.
Does it cover the GAN?
Only its math and reading. There are no mechanical reasoning or paper-folding questions, so if your local gives the GAN, practice those elsewhere.
