Mechanical aptitude test (Work Sample No. 1)

Mechanical aptitude test (Work Sample No. 1) assessing the ability to do precise work with small hand tools in tight or awkward spaces, with manual and test sheets, includes a perforated metal work sample box and a tool box containing screwdrivers, wrenches, pliers, and a variety of screws, nuts, and bolts made by Valpar International Corporation, Tucson, Arizona, United States, c. 1980.

This particular test, No. 1, assessed people’s ability to make precise finger and hand movements and to work with small tools in tight or awkward spaces. It was organized into six separately timed exercises, lasting approximately 90 minutes total. Working in whichever position was most comfortable, evaluees used small hand tools to attach and detach nuts, bolts, and screws to different sides of the work sample box through a hole in the front of the box. This served to block much of the work from view, and simulated work done in tight, awkward places. Successful completion required good motor coordination and manual dexterity. Additionally, the test allowed the observer to assess secondary work-related characteristics such as the ability to maintain physical stamina, concentration, frustration tolerance, and self-confidence.
