Electrician Aptitude Test: A Study Guide for The IBEW NJATC Aptitude Test (Includes Free Practice Test Questions)

Last updated on February 27th, 2024.

If you’re interested in joining an IBEW NJATC Apprenticeship and becoming an electrician, then you need to prepare for the IBEW aptitude test.

So if you want to:

  • Find out what an electrician aptitude test is
  • Understand what you need to know before taking the IBEW aptitude test
  • Get (free) IBEW apprenticeship practice test questions

Then you’ll love the detailed information in this IBEW aptitude test study guide.

Let’s dive right in.

What Is An Aptitude Test?

Aptitude tests are one of the most commonly used assessments in measuring a candidate’s suitability for a role.

The IBEW aims to verify that candidates possess strong capabilities in understanding written material, basic algebra, and mechanical reasoning.

The aptitude test primarily applies to the Inside Wireman and the Limited Energy Technician apprenticeship programs.

What You Need To Know Before Taking The Test

Many test-takers often tell me they regret not refreshing their math skills before the exam. Unfortunately, this oversight means they might need to wait another six months to a year for a retake opportunity.

So make sure you brush up on your math before you sign up for the aptitude test.

The IBEW aptitude test consists of two parts – math / mechanical and reading.

Math and Mechanical

The math portion covers algebra and functions with a total of 33 questions that must be answered within 46 minutes.

In addition to algebra, expect to encounter mechanical questions. You’ll need to understand pulleys, load distribution, balancing hoisted loads, and fundamental mechanical concepts.

Just remember that you must to have a balanced load (meaning the weight is centered), and more lines hoisting a load with a pulley means less stress on the ropes or cables.


The reading portion covers comprehension with a total of 36 questions that must be answered within 51 minutes. This measures your ability to obtain information from written passages. You’ll read a lengthy bit of text and then have to answer specific questions about the text.


The test is scored from 1 to 9, with 9 being the highest possible score. Most apprenticeships require a qualifying score of at least a 4 to be considered for an interview.

Aptitude Test Rules

  • Bring a photo ID to the test. Your ID will be checked. No ID, no test-no exceptions!
  • Arrive 15 minutes before the scheduled test time. Late entries will not be permitted. A late show is the same as a “No Show”. There might be a rescheduling fee.
  • Do not bring a calculator. Pencils and scrap paper are provided for computation.
  • If you do not receive a qualifying score you will not be eligible to retake the test (at any JATC in the country) for a period of six months.
    • The NJATC is very serious about this. If you retest before the six month period elapses, your score will not be valid and another six months must elapse before the next retest.

Test Time

You can expect the test to take approximately two and a half hours to complete with a break between the algebra and reading portion.

4.Consider the following formula: a = 1/2 b – 4

Which of the following statements is true for this formula?
A. When the value of b is less than 8, a is negative.
B. When the value of b is greater than 8, a is negative.
C. When the value of b is less than 8, a is positive.
D. When the value of b is greater than 4, a is positive.

Sample IBEW Apprenticeship Reading Comprehension

The reading section tests how well you can grasp and remember information. While reading a paragraph is straightforward, fully comprehending its context poses a greater challenge.

Here is a sample of what you’re likely to see on the exam:

The timing of New Year’s Day has changed with customs and calendars. The Mayan civilization, on what is now called the Yucatan peninsula of Mexico, celebrated the New Year on one of the two days when the noonday sun is directly overhead.

In the equatorial regions of the earth, between the Tropics of Cancer and Capricorn, the sun is in this position twice a year, once on its passage southward, and once on its passage northward. At the early Mayan city of Izapa in the southern Yucatan, the overhead date for the sun on its southward passage was August 13.

The Mayans celebrated this as the date for the beginning of the New Year. Later at the more northerly Mayan site at Edzna, the corresponding overhead date is July 26. Analyses of Mayan pictorial calendars indicate that they celebrated the New Year on August 13 prior to 150 AD, and on July 26 after that year.

This change has been explained by archaeological dating showing that 150 AD was the time that the Mayans moved the hub of their civilization from the southern to the northern site.


1. According to the passage, the sun at Edzna was directly overhead at noon on:
A. July 26 only
B. August 13 only
C. July 26 and one other date
D. August 13 and one other date

2. If the Mayans had moved their civilization’s center south of Izapa, their new date for the celebration of the New Year would probably have been closest to which of the following dates?
A. January 1
B. February 20
C. March 25
D. September 15

3. Based on the information in the passage, which of the following statements is true?
A. Mayans made Edzna the capital because it was more temperate than Izapa.
B. All Mayans moved to Edzna in 150 AD.
C. Mayans used calendars to mark the passage of time.
D. The Mayan city of Izapa was destroyed in 150 AD.
