Practice for Success on Your NJATC Aptitude Test

Being a technician is a profession that requires a lot of professional knowledge and responsibility. That is why the entrance test of the national electrical apprenticeship program is so complex, and candidates usually spend a few months preparing for it.

Say Goodbye to Anxiety

How exciting! You're on your way to pursuing your dream; the preparation period is filled with hopes and expectations for the future. However, many test-takers experience stress and are concerned about the test.

With specific queries in mind like:

"What type of questions should I expect to see in the test?" or "How much time should I focus on practicing polynomials?"

To more general worries like:

"What happens if I'd fail?" and "What if I'm never gonna make my electrician dream come true?".

Dear friend, I'm here to tell you not to worry. Your dream will come true if you only believe in yourself (and make the right decisions :) ).

Electric Training Alliance Aptitude Test Sample Questions with Explanations

Number Series

Please select the correct answer for the following series:

144 | 73 | 18 | 10 | 520 | ?

A. 76

B. 146

C. 247

D. 261

Answer & Explanation:

144 /2+1 = 73
18 /2+1 = 10
520 /2+1 = 261
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.
Therefore, D is the right answer.

Reading Comprehension

For the past six months, the National Union of Teachers (NUT) has been engaged in action short of striking in protest over workloads, working hours, pay and pensions. They have refused to supervise children in the playground or attend some meetings after school. Teachers have recently called for the time they spend teaching pupils to be capped at 20 hours a week, a drastic reduction in teachers' hours. In the annual NUT conference, teachers have claimed that in the past year, the number of hours they work has risen dramatically as a result of pressure from the government and the school inspectorate.

‘Teachers undermine the respect of the general public by behaving as an old-fashioned trade union and making unrealistic demands. Clearly, teaching depends on good preparation and arduous marking of pupils' work and there needs to be an allowance of time for that, but to attempt to limit the number of teaching hours when there is a great strain on finances is a ridiculous request’.

Spokesman for the Centre for Education and Employment Research (CEER) 

A. Teaching depends on good preparation.

B. Teachers are attempting to limit the number of teaching hours.

C. None of the above 

Answer & Explanation:

When looking for common ground, one should keep in mind that it is not enough to find a sentence that is true for one paragraph/passage but untrue for the other, or that is true for one passage but not mentioned in the other (although it might be inferred). In neither case would the sentence describe the common ground between the passages. Our task is to find a sentence that represents an idea existing in both passages. Distracter A, for example, is true in respect to the CEER spokesman, but the notion is not mentioned in the first paragraph, although it can perhaps be inferred from it. Distracters C and D are both mentioned in the first paragraph but not in the quotation of the CEER spokesman. Distracter B is the correct answer since the idea that ‘Teachers are attempting to limit the number of teaching hours’ appears both in the first passage: ‘Teachers have recently called for the time they spend teaching pupils to be capped at 20 hours a week’, as well as in the second passage: ‘but to attempt to limit the number of teaching hours… is a ridiculous request’.

Understanding Your Pre-Apprenticeship Test Score

  • NJATC Passing Score - The qualifying score of the NJATC aptitude test is 4/9. However, you should note that this score means something other than getting 45% of the questions correct. It means that you score in the top 4-ninths of the test takers. Therefore, this boundary is higher to reach in highly competitive areas or periods where more people apply and prepare than others. For optimal test performance, make sure you get prepared.
  • Getting an Apprenticeship - Remember, open apprenticeships are limited, and demand consistently exceeds supply. Eventually, the NJATC will select the candidates with the highest scores to continue the process, so more than just passing is needed.
  • Retake - You can retake the NJATC test multiple times. The only limitation is that you have to wait 6 months between attempts.

NJATC Apprenticeship Overview

Considering the wide range of positions in the electrical field, we will try to give the reader a rough estimation of what they can expect to learn throughout the apprenticeship process and the divide between classroom and on job training hours.

Theory – In classroom, textbook training can run between 576 and 1,000 hours, depending on the type of position you are looking to fill.

On the Job – Training on site will usually run between a total of 8,000 and 10,000 hours.

Topics according to positions

  • Inside Wireman – This job could be conducted in a variety of settings, including commercial building. The job is very varied and includes establishing temporary power during construction and more. Knowledge and skills sets include first aid, using electric schematic diagrams, and having a firm grasp of the national electrical code.
  • Outside Wiremen: These are the guys who install and maintain outside powerlines, insulators, transformers, and towers. It is therefore incumbent to have a wide range of skills from working with Delta and Wye Transformer Connections, to tying knots, and understanding and using blue prints and symbols among others.
  • Residential Wiremen: These workers are tasked with a wide range of responsibilities, including running hot checks, installing grounding systems, and planning and initiating projects. Therefore, you will have to know the principles of grounding, understand how to work with dangerous materials, know which wires are appropriate for various situations, and more.
  • Telecommunications Installer: These job includes working with security and access control, computer networks, and other such systems. You will need solid knowledge of (LAN) cabling systems, installing low voltage wiring, and testing and repairing data systems among other projects. You need many skills in your tool box like splicing copper, coaxial and fiber optic cables or troubleshooting through segmentation and isolation to just mention a few.

Panel Interview

You will be interviewed by a panel consisting of the director of the apprenticeship and members of the local union office and NECA.

Be prepared for questions on experience, conflict resolution, how you like to work, and why you have chosen the field at hand.

NJATC Test Provider

The leading authority responsible for the electrical apprentice candidates’ assessments is the Electrical Training Alliance (NJATC). Becoming a licensed electrician requires passing the Electrical Training Alliance test.


Can I retake the test if I fail?

Yes, you can retake the test, but only after a lapse of 6 months. The Electrical Training Alliance is strict on this point, so if you take the test prior to 6 months passing after the first test, it will be disqualified.

Can I arrive late to the test?

If you come late you will be denied entry and there may be a fee for rescheduling the exam.

What is the hardest part of the test?

While of course, everyone has their strong and weak points, for most people it would be the math segment. JobTestPrep will help you fully prepare by providing you with a comprehensive study guide, practice tests and answers, and testing tips.
