What is mechanical reasoning?

Mechanical reasoning is your ability to understand and apply mechanical concepts in order to solve problems. Mechanical aptitude tests are regularly used in the hiring process for more technical job roles.

What do Mechanical Comprehension Tests measure?

Mechanical Reasoning Ability is one of the 4 specific abilities measured by recruiters. It is required in a number of highly manual or technical roles, particularly in fields such as engineering, airlines, the emergency services and skilled trades. BMCT-ll was developed to measure the following abilities that are required for success in specific job roles or training courses:

  • Mechanical comprehension
  • Spatial Visualisation
  • Knowledge of basic physical and mechanical laws
  • Deduction of how machinery works

BMCT is a proven predictor of performance in roles requiring knowledge of these abilities. In addition those with higher BMCT-II scores are more likely to have greater spatial awareness.

What are Mechanical Ability Tests used for?

For more than 60 years BMCT has been used as an objective and valid assessment to identify candidates with good spatial perception and mechanical reasoning abilities, as well as those with an aptitude for learning mechanical processes and tasks. It is used in three primary applications:

  • Recruitment: For job roles across a wide range of industry sectors, including electrical, engineering and mechanical roles. The test is used to evaluate a candidate’s understanding of mechanical reasoning and spatial awareness.
  • Training: The test can also be used to predict how well a candidate will learn key concepts in an educational training course related to mechanical reasoning. Pre- and post-tests may be given to gauge the trainee’s learning and the effectiveness of the training program.
  • Risk Management: Hiring individuals with poor mechanical reasoning for roles that involve driving, using heavy machinery, repairing equipment, or similar tasks could result in workplace injuries and equipment damage. Screen potential candidates for their mechanical aptitude.

What is the format of the Bennett Mechanical Comprehension Test?

The online format and item-banked items allows off-site, unproctored screening early in the hiring process, with no two applicants receiving the same set of questions.


  • 55 items to be completed in 25 minutes with 2 practice questions untimed
  • Presenting items from a large bank renders screen-sharing of questions pointless as no two candidates will receive the same set of items. This stops over-exposure of items, thus protecting the integrity of the test.
  • Online for unsupervised and/or supervised completion.
  • Easy to administer. Online test link can be sent to any number of test-takers with one click.
  • Test and reports available in over six languages, allowing it to be used internationally.
  • Has a very high equivalence to the BMCT-l at 0.81.

Case Study

Read in full the BMCT findings of John Becker, Director of Education at a Major Automotive Transport Company in the USA.

“At each point those scoring higher in the BMCT have lower staff turnover AND greater revenue than those scoring below that percentile.”
