Electrical Aptitude Test
If you are seeking an electrician job, you will be required to take and pass the electrical aptitude test to be hired.

The Electrical Aptitude Test is designed for people who want to become electricians through apprenticeship. Once you submit a qualifying application, you will be scheduled for a testing date.

The Electrical Aptitude Test consists of various sections, including math and reading comprehension.

The math section comprises thirty-three questions within forty-six minutes, while the Reading Comprehension section contains thirty-six questions within fifty-one minutes.

You will experience a short break between the two sections, and your score will be based on the number of items you can answer accurately.

Make arrangements with the training center during the test as soon as you receive your aptitude test date if you will require special accommodations.

An independent facility scores the Electrical Aptitude Test. Approximately two to four weeks after your test is over, the training center will receive the results and then notify you of the results by email.

You will be offered an oral interview if your score meets the qualifying score for an interview.

Interviews are done once every year in February and March.

However, you will have to wait six months before applying and retesting if you don’t obtain a qualifying score on the test battery.

  • Average
  • Below Average
  • Low
  • Below Minimum
  1. What happens if I fall sick or have an emergency on the test day?

If you will not be able to take the test on the scheduled date due to an emergency or illness, you need to contact JATC immediately – if you are still interested in the test – to review your situation and application and reschedule you for the next available test session, or you will have to reapply.

Remember that you can have your test date rescheduled only once. This means that you would have to reapply with the JATC if you can’t attend your rescheduled test date.

  1. Will I be allowed to complete the test on another day if I have to leave before the test is completed?

No, you will not be allowed to complete the test on another day based on the condition of leaving before finishing the test.

The grade of your test will be determined as if you did finish the test and your score will certainly be lower than if you had completed the test when you cannot complete each section of the test.

During your test session, the tests must be completed. You will not be able to take the test again for a minimum of six months if you cannot complete the test on another day.

  1. The Electrical Aptitude Test tips

Ensure you arrive fifteen minutes early on the day you are taking the electrical aptitude test to make sure you are not late.

Late entries will not be condoned and will attract a fee because you are marked as not present and therefore will have to reschedule your test.

Remember to bring a photo ID, as mentioned above. You may not be allowed to use a calculating device during the test, but scrap paper and a pencil will be provided to work out the equations.

A little break will be given between the two sections of the electrical aptitude test, which allows for stretching and eating before going back in.

You will have your focus and energy regained with this.

You can skip the questions whose answers you are unsure of and come back to them later. This technique will help you a lot because only the correct answers make up your score as incorrect ones will not count.
