Multi-level sorting test (Work Sample no. 7) assessing the ability to sort things quickly based on complex criteria, with manual and test sheets, includes 144 coloured plastic chips, case, and slotted testing board, made by Valpar International Corporation, Tucson, Arizona, United States, c. 1980.

This particular test, No. 7, assessed people’s ability to make rapid sorting decisions based on complex criteria. Evaluees sorted 144 plastic chips into correct slots by colour, letter, number, or a combination of these. Two administrations of the test were recommended; each one took about 15 minutes. Good performance depended on form perception, motor coordination, finger dexterity, manual dexterity, and colour discrimination. Additionally, the test allowed the observer to assess secondary, work-related characteristics such as concentration, communication skills, decision-making ability, frustration tolerance, and problem conceptualization.
