How To Ace the IBEW Math Test?
The IBEW electrical aptitude test and especially the math section in it is considered more difficult than other common pre-apprenticeship tests.
The mathematical concepts required in the electrical IBEW aptitude test (functions, polynomials, etc.) are more complex than those found in nearly all apprenticeship tests. Therefore, this preparation includes an emphasis on the math section.
To get thorough practice for the IBEW and ensure you are sharpening your math skills, get our full prep course.
IBEW Reading Comprehension Sample Test
Candidates often overlook the reading comprehension section of the IBEW Apprenticeship Test because it isn't as intimidating as math.
Don't make that mistake.
The reading section on the Electrical Aptitude Test determines half your score - ensure you prepare for it properly.
This test measures your proficiency in obtaining information from a given text.
Question #9
A coronary stent is a metal tube placed in the coronary arteries to keep them open to treat coronary heart disease. The cardiologist uses a projectional radiographer to assess the location and estimate the blockage's size by injecting a contrast medium through the guide catheter and viewing blood flow through the downstream coronary arteries. Intravascular ultrasound may be used to assess the lesion's thickness and hardness. The cardiologist uses this information to decide whether to treat the lesion with a stent.
How many electrical medical instruments may the cardiologist use?
A. One
B. Two
C. Three
D. Four
Question #10
Recruiters spend their time building relations with prospective employees or people who could refer them to talent. Social media, in general, has increased the ability to develop and maintain connections with people. Since social media has proved to accelerate relationships and knowledge of these relationships, that information can be better used to support all human resources needs. Social tools can be used to manage compensation, benefits, acquiring talent, grooming talent, aligning employee success with business success, matching like-minded employees, and cultivating innovation within the organization.
How can social media tools be employed in HR departments?
A. Compensate workers in case of loss of competencies
B. Developing innovative applications for social networks
C. Recruiters can be referred to potential talents
D. Further investigate people's privet life for matching
How To Ace the IBEW Reading Comprehension Test?
You can practice for the Verbal Comprehension section of the NJATC Electrical Aptitude test (The National Joint Apprenticeship and Training Committee) even when you are not actively preparing. How?
Read. As much as you can, whenever you can.
Don't just skim-read. Ask yourself questions about what you just read. Try to draw conclusions from the text, detect its fallacies, or summarize it in your own words. Your ability to solve reading comprehension questions will skyrocket, and you wouldn't even notice.
You can find these strategies and dozens of verbal reasoning practice tests on the preparation course.

Comprehensive Explanations for the Answers
Answer #1
If a = ½ b + 1, then a = 0 when b = -2. Thus, a > 0 when b > -2 and a < 0 when b < -2. Only answer (C) supports this conclusion.
Therefore, the correct answer is (C).
Identify like terms:
Rearrange terms so that like terms are together:
Combine the like terms:
Hence:
Therefore, the answer is (D).
You probably did not combine the like terms correctly if you chose any other answer.
Remember the following formula:
The line equation is: 
slope, 
the intersection point of the line and the y axis.
You can infer from the sketch that the line intercepts the axis when: 
.
Accordingly:
1.The intercept points of the function and the x and y axis are: 
.
2.
.
Find the slope of the function:
Find the equation of the line:
Accordingly, the answer is (A).
If you chose answer (B) or answer (C), review your calculations, especially the slope formula. If you chose answer (D), review your calculations, especially the line equation definitions.
Method A:
In order to understand the range of the expression, evaluate the numerator and denominator separately:
To simplify, assume the following formula 
In this expression, the numerator is greater than the denominator: 
;
Alternatively:
Therefore, the fraction is greater than 
, so you can eliminate answers (A) and (D).
Next, evaluate whether the expression is between 
and 
or 
and 
, by evaluating 
:the numerator 
is smaller than the denominator 
; this makes the fraction less than 
: 
.
Now, evaluate 
; the fraction is always less than 
.
Method B:
Another way to solve this is to substitute numbers into the unknowns.
Note: the substitution has to fit the data given in the question.
, thus substitute 
, thus substitute 
, thus substitute 
The expression is between 
and 
, 
; therefore, the correct answer is (B).
If you chose any other answer, review the explanation and the definition of fractions.
This question deals with a single variable equation.
When solving a single variable equation, the goal is to isolate the variable (mostly called x) to find its value.
The way to do that is by gathering all variable-expressions of the equation (one or more X-expressions) on one side and all numerical members of the equation on the other side. This is done using the four operations (+, -, *, /) in the equation, as needed.
Important! Any numerical operation must be applied on both sides of the equation.
On this case, to isolate X apply the following operations to both sides of the equation:
15 + 3X - 6 = 7X + 11- 2X
9 + 3X = 5X + 11
1. Subtract 3X
9 + 3X - 3X = 5X + 11 - 3X
9 = 2X + 11
2. Subtract 11
9 - 11 = 2X + 11 - 11
-2 = 2X
3. Divide by 2
-2/2 = 2X/2
=> -1 = X
Note that 
is positive.
The value of 
is squared, so it must be positive.
Therefore, the answer is (B).
If you chose any other answer, you probably did not reduce correctly.
There are two ways to look at this series:
(1) There are two inner series. each following a different rule:
Odd terms- remain constant: 3.
Even terms- increase by 3:
3+3=6, 6+3=9, 9+3=12.
(2) Another point of view: 
The series in this question follows two rules:
(1) The mathematical operations between the terms change in a specific order, x, : and so forth.
(2) Every two steps the number by which the terms are multiplied or divided increases by 1.
Notice the question referring to electrical Instruments: "The cardiologist uses a projectional radiographer to assess the location and estimate the blockage size by injecting a contrast medium through the guide catheter and viewing the flow of blood through the downstream coronary arteries. Intravascular ultrasound may be used to assess the lesion's thickness and hardness." – that is, TWO electrical instruments. Therefore the answer is B.
According to the passage: "Recruiters spend their time building relations with prospective employees or people who could refer them to talent. Social media, in general, have increased the ability to build and maintain relations with people." So social media can assist in the task of referring new talent. Answer (A) is incorrect. Although compensation is mentioned in the passage, it does not say anything about the loss of competencies. (B) and (D) are not mentioned in the passage at all. Therefore the answer is C.
How To Ace the IBEW Aptitude Test?
The standard passing score of the IBEW aptitude test is 4/9. However, getting the bar score doesn’t necessarily mean you’ll get an internship since open apprenticeships programs are limited and demand consistently exceeds supply. Eventually, the IBEW will select the candidates with the highest scores to continue the process, so just passing is not enough. Therefore, for optimal test performance that will grant you with NJATC internship, it’s better to prepare appropriately and rise above the competition.
Using an accurate and proven practice plan that includes full-length IBEW practice test simulations of the actual test will eliminate the guesswork and enhance your chances of scoring high.
Frequently Asked Questions
The International Brotherhood of Electrical Workers (IBEW) and the National Electrical Contractors Association (NECA) form the Electrical Training Alliance (used to name the National Joint Apprenticeship and Training Committee (NJATC). Your path to becoming an electrician goes through passing the IBEW Aptitude Test and (previously JATC Test or NJATC aptitude test).
