About mechanical aptitude tests

Candidates from a wide range of industries may encounter these tests: Army, medicine, engineering, crafts men, and any job that involves the maintenance, operation and  fixing of mechanical equipment. The difficulty level of these test varies according to the required skills.

What does the test look like?

A mechanical aptitude test is usually administered on a computer or in paper and pencil form. Each question has one correct answer, and there are usually three or four optional answers to choose from. Since most questions do not require complex calculations, there are usually no more than 40 seconds per question.

Most mechanical reasoning tests introduce basic concepts of Newtonian mechanics and electricity, the same concepts that are covered in a GCSE level curriculum. However, unlike in GCSE tests, less calculations are required, and it is more about understanding concepts.  Here is a list of the most popular subjects that appear in these tests:


  1. Forces and motion - acceleration, gravity, friction, pressure, moments, etc.
  2. Energy - transformation, kinetic and potential energy, work and power.
  3. Popular questions:  levers, pulleys, screws, gears, springs, etc.


  1. Circuits - parallel, series.
  2. Voltage, resistance, current, capacitors, and charge.
  3. Magnetism
  4. Popular questions: Circuit diagrams, etc.


  1. Conventions and units.
  2. Tools, terminology.

What is an SHL Verify Mechanical Comprehension Test?

SHL is one of the largest pre-employment test providers worldwide. The Verify Mechanical Comprehension Test is an online, unsupervised aptitude test which SHL administers at the beginning of the assessment process along with other Verify tests. If you are applying to mechanical or technical positions and are about to be assessed by SHL, odds are you will be required to sit this test.

On the test, you are required to interpret images depicting simple mechanical concepts such as levers, gears and pulleys. The test involves 15 questions to be answered in 10 minutes. If you pass this test you will be invited to the assessment centre to continue the assessment. You will then be required to sit a supervised Mechanical Comprehension Test to vouch for your initial score. It is very important to practice in order to increase your chances of getting a chance at the assessment centre. JobTestPrep's preperation pack includes SHL style questions, answers and explanations.
