Criteria Mechanical Reasoning Assessment (CMRA)

Updated 5 months ago by Amy Tranter

The Criteria Mechanical Reasoning Assessment (CMRA) measures a candidate’s mechanical aptitude and reasoning ability. It's a short, mobile-friendly test that can predict performance for occupations involving the operation, maintenance, and servicing of tools, equipment, and machinery.

The reading level for the CMRA is estimated at a sixth-grade level, and the content is designed to refer to everyday situations and thus minimise the gender and racial/ethnic bias that can occur in other traditional mechanical aptitude tests. Therefore, this test can serve as a valid and reliable predictor of performance for a wide variety of mechanically inclined jobs, while demonstrating less adverse impact across demographic subgroups than many other tests of mechanical aptitude. 


The CMRA is a timed test with 30 multiple-choice test items. Candidates have 15 minutes to answer these questions. The test is also dynamic, so that each item for an individual candidate is pulled from a larger item pool, with difficulty levels predetermined for all items. This allows for all candidates to receive the same number and overall difficulty of items while encountering a relatively unique selection and ordering of items. 


The CMRA test content encompasses various areas that are representative of mechanical reasoning, including weight distribution, fulcrums, air flow, buoyancy, gears, pressure, momentum, speed, light, force, and other related subject matter. By targeting all of these areas of mechanical reasoning, the test triangulates on mechanical reasoning more effectively than other comparable instruments, while also providing a broader measure of general mental ability than these narrower tools.  

After completing the assessment, each candidate receives a Raw Score, which reflects the total number of items answered correctly (with no deductions for incorrect responses), as well as a Percentile Score, which reflects how the candidate performed relative to others who have taken the test. For example, a percentile score of 45 means that a candidate scored better than 45% of the group on which the test was normed. The report also provides suggested raw score ranges based on normative data relating to a selection of commonly assessed occupations.
