Mechanical Understanding Test (MUT) Technical Manual

Over the next year HRD Press will update and market the entire product line previously developed by Performance Management Press. Dr. Erich P. Prien will maintain overall technical supervision of these changes and will be assisted in these efforts by Dr. Leonard D. Goodstein of Washington, DC. Mechanical Understanding Test (MUT)

The first of these updated products is now available. The Mechanical Understanding Test (MUT), formerly named the Work Skills Test, is a 65-item, 30-minute test of the comprehension of mechanical principles. There is a new, more comprehensive manual available and an enlarged and enhanced norm base
(n = 1,000+).

The MUT is a gender-unbiased measure of mechanical comprehension, i.e., there are no differences between the average scores of men and women. This is in sharp contrast with the other tests of mechanical comprehension, which have a strong male bias. Yet, despite having no gender bias, the MUT is as predictive as any other measure of this important characteristic. Also, the standardization of the MUT has revealed no systematic racial or ethnic differences.
