IBEW Aptitude Test Sample Practice Questions & Answers


IBEW Math Practice Questions

Sample Algebraic Equations Question

Consider the following formula: A = B + 3 ( 4 – C )
If B equals 5 and C equals 2, what is the value of A?

  1. 7
  2. 11
  3. 12
  4. 17


Answer and Explanation

In a case where values for all variables but one are given, it is recommended to start by replacing them all with their values:

A = 5 + 3(4 - 2) = 5 + 3x2 = 11

The answer is, therefore, B.

Sample Polynomials Question

(A-5)2 x (A2-25) = ?

  1. (A-5)4
  2. (A-5)2 x (A+5)2
  3. (A-5)3 x (A+5)
  4. (A4-125)


Answer and Explanation

Looking at the second element, we can see that it follows the well-known form of:

(a2-b2) = (a-b) x (a+b), namely:

(A2-25) = (A-5) x (A+5).

Therefore, the complete expression equals:

(A-5)2 x (A-5) x (A+5) = (A-5)3 x (A+5)

The correct answer is C.

Sample Functions Question

Consider the following table:

9 1
18 2
27 3
36 4
45 5

Which of the following choices represents the same relationship as demonstrated in this table?

  1. Y = 2X + 1
  2. Y is equivalent to the sum of the value X and a constant C, where C equals 3.
  3. X Y
    2 0.222
    3 0.333
    6 0.666
    10 1.111
  4. IBEW Aptitude Test Sample Question


Answer and Explanation

As can be seen from the table, the relationship is Y = X / 9:

1 = 9 / 9
2 = 18 / 9
3 = 27 / 9
4 = 36 / 9
5 = 45 / 9

Answer (A) is incorrect because if Y = 2X + 1, then when X = 9, Y = 19 instead of 1.

Answer (B) is incorrect because if Y = X + 3, then when X = 9, Y = 12 instead of 1.

Answer (D) is incorrect because in the given table, X is always greater than Y, and in the graph, Y is always greater than X.

Only answer (C) represents the same relationship:

2/9 = 0.222

3/9 = 0.333

6/9 = 0.666

10/9 = 1.111

Therefore, the correct answer is C.

Sample Number Series Question

144 | 73 | 18 | 10 | 520 | ?

  1. 76
  2. 146
  3. 247
  4. 261


Answer and Explanation

Every two terms are a pair. The first number is divided by two and then increased by 1 in order to produce the second term.

144/2+1 = 73
18/2+1 = 10
250/2+1 = 261

Therefore, the correct answer is D.

Sample Inequalities Question

If |3x + 8| > 12, which of the following represents all possible values of x?

  1. x < -20/3; x > 4/3
  2. -20/3 < x < 4/3
  3. x > -4/3
  4. x < -20/3


Answer and Explanation

If |3x + 8| > 12, then there could be two options:

3x + 8 > 12 OR 3x + 8 < -12.

Let's look at each option separately:

3x + 8 > 12

After combining like terms we yield 3x > 4

After dividing both sides of the inequality by 3, the result is x > 4/3.

3x + 8 < -12

By implementing the exact same process, we yield x < -20/3.

Remember: Both answers are possible!

Therefore, the correct answer is A.


IBEW Verbal Practice Question

Sample Reading Comprehension Question

Last year, road fatalities decreased by 9%. According to the latest figures published by the Department of Transportation today, this year has seen the lowest number of deaths in road traffic since records began. However, road deaths are only the tip of the iceberg, because for every death on US roads there are 10 serious injuries such as damage to the brain or spinal cord. Country by country statistics shows that the number of road deaths per year still varies greatly across the US with the countries reporting the lowest number of fatalities being California, Oregon, Washington, Vermont, and Maine, with only 30 deaths per million inhabitants. Vulnerable road users such as pedestrians, cyclists, motorcyclists, and users in certain age groups, notably the elderly, are particularly affected by serious road injuries.

Which of the following statements is correct?

  1. Cyclists should be banned from riding on the roads.
  2. More animals are killed by cars than by pedestrians.
  3. Road deaths are on the rise in Vermont.
  4. There are more serious injuries than deaths.


Answer and Explanation

Option D is correct. This is what the text states: "for every death... there are 10 serious injuries".


IBEW Apprenticeship Test Score

The standard passing score of the electrical aptitude test is 4/9. However, you should note that this score DOES NOT mean getting 45% of the questions correct. It means that you score on the top 4-ninths of the test takers.

Therefore, in highly competitive areas or times, where more people tend to apply and prepare, this boundary might be higher to reach than in other areas or times.

In addition, remember that open apprenticeships are limited, and demand always exceeds supply. That means that eventually, the IBEW will select the candidates with the highest scores to carry on with the process, so just passing is not enough.

A Word about IBEW Locals

One of the most frequent questions I get is "is the IBEW test conducted by local X?". The answer is yes. All IBEW locals use the same version of the test because this is the exact reason this test was designed, to begin with - to provide a standard, uniform measurement scale for all U.S IBEW locals.

How to Practice and Pass the IBEW Test?

When candidates for the IBEW apprenticeship program face an aptitude test, many of them get discouraged. It immediately takes them back to memories of blackouts, anxiety, and the feeling that their professional future rests on math and reading comprehension drills.

We get weekly emails from genuinely disheartened and frustrated candidates, who know they could be excellent electricians, if only they could get away with the aptitude test.

It doesn't have to be that way.


Now, let's get into the 3 greatest challenges the IBEW Aptitude Test puts before you, and how to overcome them.

The Challenges of the IBEW Apprenticeship Test and How to Pass Them

Compared to the things you’ll learn and deal with as an electrician, the Electrical Aptitude Test isn’t that difficult in and of itself. And yet, it still gets to confuse and annoy so many good candidates.

So, what is it that makes this particular test such a challenge?

Over the past years, we’ve connected with dozens of IBEW test-takers. Here are their top 3 answers:


Challenge #1 – Uncertainty

I assume you have already done some research about the IBEW apprenticeship test. You may have noticed that the IBEW and the NJATC disclose very little about it. Usually, all you get is that it is a “Basic Math and Reading Aptitude Test” or something similar.

This lack of information keeps most candidates confused about what, how, and when to learn.


Overcoming Uncertainty - Practice the Real Thing

What do you do when you are anxious about a certain task? You do it in advance. That is true for speaking in front of an audience, rock climbing, or aptitude testing. And the closer your practice is to the real task, the simpler it will eventually be.

The more you sweat in training, the less you bleed in battle.

I can tell you, understanding how the real IBEW Apprenticeship Aptitude Test looks like wasn’t easy. But, through meticulous data collection from dozens of candidates, we have been able to bring forth their experience to help YOU.

Important note: The PrepPack DOES NOT contain the exact IBEW Test you’ll be having. That is both impossible and illegal. It DOES contain the closest practice experience that could be made.


Challenge #2 – Material

Not only is the IBEW Test’s material something you probably haven’t seen in years (when was the last time you solved a polynomial??) it also connects directly to where most people tasted failure for the first time – school.

Both math and reading comprehension immediately relate to what most people experienced as a challenge in school. These bad memories often get them discouraged before they even started.


Overcoming Material - Customize Your Practice

To get professional in the IBEW Aptitude Test material, keep the 2 following guidelines in mind:

#1 – Customize Your Practice to the Test Level

No one expects you to be a math professor. To become an electrician, you need to show that you have the ability to learn and solve IBEW test-level questions.

Were you ever taught in school that: “It’s not the result that counts but the way you solved it?”

Forget about it. Here it’s ALL about the result. It’s all about technique. And that is what you should do.

Create a Personalized Practice Plan and Focus on Your Weak Areas

#2 – Customize Your Practice to Your Level

Before you start, understand exactly where you stand on each and every test topic. That way you will get the most precise, personalized, and effective preparation for your needs.

The thing is, most people don’t REALLY know their strengths and weaknesses. You may know you’re weak in math, but what math? Equations? Number series?

That level of detail may seem trivial, but it is crucial if you want your preparation to be effective, especially if you’re short on time.

Look into your skills thoroughly and sincerely, down to the subject level.

A Progressive Practice to Take You All the Way from Level 0 to Above Real-Test-Level

What’s in the PrepPack?

Why is it in the PrepPack?

Progressive question level – from beginner to slightly above test-level

Build your solving skill from the ground up, until IBEW level questions are a little too easy for you.

The questions on this IBEW practice test were a little more difficult than my actual test so that filled the difference I was missing with my test anxiety. It's a little expensive but I would still recommend 10/10.

Challenge #3 – Time Constraints

Like in many aptitude tests, the main difficulty of the IBEW Test is not the questions themselves, but rather the short time given to answer them. That requires you not only to learn how to solve, but how to solve FAST.


Overcome Time Constraints - Practice in-Depth

To be able to quickly recognize questions and maximize your solving speed, it is important to practice in-depth – that is, to solve a high number of questions on the same topic, one after another.

That way you get more familiar with the material, better to memorize, and quicker to recognize patterns you have already encountered.
