Simulated assembly test (Work Sample no. 8) assessing the ability to perform conveyor-belt type assembly work, with manual and test sheets, containing rotating phonograph-like disk with holes along rim, and three bins containing small parts coloured white, gray, or black, made by Valpar International Corporation, Tucson, Arizona, United States, c. 1980.

This particular test, No. 8, assessed people’s ability to perform conveyor-belt type assembly work. As the flat disk turned at a constant speed (adjustable up to 12.5 RPM), evaluees assembled stacks of three small parts taken from part bins beneath the disk, completing as many stacks as possible in 20 minutes. The machine kept a count of completed assemblies and recycled used parts into the parts bins. Good performance depended on motor coordination, finger dexterity, and manual dexterity. Additionally, the test allowed an observer to assess secondary, work-related characteristics such as ability to follow instructions, stamina, self-confidence, and motivation.
