What Is the Bennett Mechanical Comprehension Test (BMCT)?

The Bennett Mechanical Comprehension Test (BMCT), developed by Pearson Assessments, is a popular assessment used in several fields, including technical and industrial occupations. The test was developed to measure a person’s aptitude for understanding and applying mechanical principles. From this, an employer may infer future performance in jobs that require these skills.

What Do Those Who Score High Receive?

Scoring high on the BMCT displays good spatial perception and mechanical reasoning ability. It also shows your knowledge of basic mechanical operations and physical laws, as well as an aptitude for learning mechanical processes and tasks. This, in turn, shows employers that you are a qualified candidate, thus heightening your chances of getting the job you applied for.

What Are the Challenges to Passing?

The BMCT is a timed test. On the BMCT II, you need to answer 55 questions in 25 minutes. By practicing for the test, you can improve your timing on the exam.

Bennett Mechanical Comprehension Test (BMCT) Test Format & Content

There are two versions of the BMCT: BMCT and BMCT II.

The BMCT consists of 68 multiple-choice questions and has a 30-minute time limit. It can be administered on paper or online. It is currently available in two forms, Form S and Form T.

The BMCT II consists of 55 multiple-choice questions and has a 25-minute time limit. It is administered online only.

The Bennett Mechanical Test is used to identify individuals with good mechanical reasoning abilities and spatial perception. For those who plan to take the BMCT, it is important to be familiar with basic concepts in physics as well as physics terminology.

Who Is Required to Take the BMCT?

Individuals who work in the following industries may be required to take the BMCT:

  • Engineer
  • Automotive mechanic
  • Equipment operators/transportation trades (truck driver)
  • Automotive and aircraft mechanic
  • Industrial/technical sales representative
  • Installation/maintenance/repair
  • Skilled tradesperson (welder, electrician, carpenter)
  • Mechanical trades


  • It is important to take the test in a quiet, well-lit room. Make sure to have comfortable seating; an adequate desk; and comfortable positioning of the computer screen, keyboard, and mouse.
  • Handbags, briefcases, and other personal materials are not allowed on or near the work surface. Examinees may not use reference materials, books, or notes to take the test, and such materials must be placed out of reach.

The BMCT Is Used to Assess the Following

  • Mechanical aptitude
  • Spatial visualization
  • Application of physics
  • Deduction of "how things work"

On the BMCT I, there are 136 items split into 18 categories of mechanical principles:

Category Number of Items
Acoustics 3
Belt Drive 2
Center of Gravity 7
Centrifugal Force 5
Electricity 6
Gears 10

Prepare for the BMCT Online

JobTestPrep's Bennett Mechanical Comprehension Test practice pack covers mechanical aptitude topics seen on both the BMCT & BMCT II. The Bennett–style practice tests can be taken in real-time simulation mode (to reflect similar test conditions) or in step-by-step mode.

Our pack offers two simulations for the BMCT and two simulations for the BMCT II. Like the real tests, the BMCT practice tests contain 68 questions each, while the BMCT II practice tests contain 55 questions each. It's important to note that the questions for both versions of the test overlap, although they are different in style. Additionally, while the questions may seem vague in style, this is intentional to model the real exam. This style forces candidates to really assess the questions, and it also justifies the difficulty of the exam. Reading our detailed answer explanations will help you to increase your understanding of the test's style and content, as well as ensure that you do well on the exam. 

Also included is a study guide containing information, sample questions, and solutions on mechanical and electrical reasoning. Want to stand out among other applicants? Start preparing today to ensure your success.
