Technical Facts

Timed test

Each test is different, but they are almost all timed, which is why it is essential to practice in advance and be ready to answer each question correctly as quickly as possible. Here are some examples of possible test structures:

  • Multiple-choice questions in electrical concepts, mechanical reasoning, numerical, grammar, technical, and reading comprehension.
  • 69 multiple-choice questions in algebra and reading comprehension; 96-minute time limit.
  • 10 questions in math, reading comprehension, and practical applications; 10-minute time limit; 80% minimum score required.

Application process

When you apply to become a trade entrant, you will have to complete the following application process:

  1. Apply for the trade union aptitude test. You will probably be required to show proof of a diploma or high school equivalency.
  2. Take the test. This is where you can shine if you practice enough in advance for the exam.
  3. Undergo an interview.


Bring photo ID. If you forget your ID at home, you will not be allowed to take the test and you will lose your registration fee.

No calculators are permitted.

Is the test taken online?

The test is usually computerized and will be administered at your local testing station.

What should I study for the test?

We recommend that you have at least a basic command of high-school-level reading comprehension and basic math skills such as arithmetic, pre-algebra and algebra to be comfortable taking the exam. Practicing with iPrep will improve your scores and help you get ready for exam day.

Are there other tests once I start my training?

At the end of your training, you must pass the journeyman exam to become a certified tradesperson holder. This is a difficult professional exam, which does not focus on general aptitude but on the professional knowledge gained during your training. However, it should not be confused with the trade aptitude test.

The trade aptitude test is very crucial. On the one hand, you do not need to prove professional knowledge, only basic skills. On the other hand, if one doesn’t pass it, one will not get the chance to gain professional knowledge and to become a skilled tradesman or a tradeswoman.

    I only rated it 4 stars because I like to learn by videos and hear people talk about what they are doing. especially when learning things that are new to me, But other than that I do believe it will prepare me enough to take the test and pass.

    Was a great provision and review of the exact same math concepts I had on the aptitude test. Though the mechanical questions were fun to learn about, the test I took a few days ago didn’t include any mechanical knowledge questions.
