The WTMA is a written test of mechanical aptitude.
Mechanical aptitude helps people learn about and use tools, machines and equipment.
The test is designed for use in selecting entry-level personnel for jobs involving the operation, maintenance, and repair of mechanical equipment of various types. The WTMA measures basic ability rather than formal schooling or job experience. The test asks questions about everyday objects and situations. The WTMA is designed to be fair to both men and women. The test content is not gender-biased, and the difference between the average scores of men and women is much smaller than is seen with other, more traditional tests.
