Bennett Mechanical Comprehension Test

IMPORTANT NOTICE - The BMCT S & T and both Randomized versions will be DISCONTINUED AND UNAVAILABLE as of December 31, 2016. Only the NEW Bennett-II will be available after that date.

As of September 1, 2016 no new BMCT Form S/T or Randomized administrations may be purchased. Previously purchased versions may still be administered and scored but new purchases must be the BMCT-II.

When you need to determine quickly and surely if a job applicant has the aptitude to learn mechanical skills, you need the Bennett Mechanical Comprehension Test.

In only 30 minutes, the BMCT results help you decide who is best suited for jobs requiring a grasp of the principles of operation and repair of complex devices. The 68 BMCT test items are presented in terms of simple, frequently encountered mechanisms and require no special knowledge. Items do require the application of a physical law or mechanical operation and focus on spatial perception and tool knowledge rather than manual dexterity.

The BMCT may be self-administered in paper format or online, read aloud by an examiner; or administered using a taped recording of the questions. You may administer it to a single applicant or a group. The first forms of the BMCT were prepared for use in the US military and many of the Allied countries. Current forms have been refined in more than 50 years of research and use. The manual was revised in 1994 and contains 18 new norms tables, based on cases collected in 1993 and 1994. Updated test booklets retain original items but have a contemporary look. Answer sheets and score keys have been redesigned to make them easy to use.

New - Randomized Version

The randomized version of the Bennett Mechanical Comprehension Test will present items in random order for each test administration, thereby increasing the security of the assessment. The system uses a random number generator to continuously alter the presentation order from the pool of items.

Reliability coefficients range from .81 to .93, indicating that the BMCT is a consistent measure. For jobs requiring multiple aptitudes, the BMCT is most effective when used in combination with other tests.

• Individual or group administration
• 30 minutes (stopwatch required)
• Two alternate Forms S and T
• Hand or machine scorable
• Fourth grade reading level

This assessment is only to be administered in a proctored setting. The test administrator will take necessary steps to ensure the test is always administered in a proctored and secure environment.

NEW - Version II (Fall 2014)

The Bennett Mechanical Comprehension Test® II measures the ability to apply physical and mechanical principles in practical situations. The assessment evaluates an applicant’s problem solving skills and ability to learn new mechanical concepts quickly. It is ideal for use in a wide variety of occupations in production and maintenance.

In response to client requests and preferences, the new report also presents the score in four different ways:

Percentile against a norm reference group

T-scores that are standardized scores used to compare a test taker’s results. A

T-score has a mean of 50 and standard deviation of 10

STANINE (Standard Nine) scores are standardized scores based on a 9-point scale, with a mean of 5 and standard deviation of 2

STEN (Standard Ten) scores are standardized scores based on a 10-point scale, with a mean of 5.5 and a standard deviation of 2

No matter which method of presenting scores is preferred, they all allow for comparison of a test taker’s score relative to the normative reference group. No score is more accurate than another.

Each administration will present 55 items. Administration time is 25 minutes.

The BMCT-II is available in both paper and online formats.
