Mental ability tests in clerical selection

Abstract

82 key punch operators were given a battery of three clerical tests: Minnesota Numbers, Hay Number Series Completion, and Hay Name Finding. Scores on the Wonderlic Personnel Test were also available for this group, divided into 53 "good" operators and 29 "poor" ones. 30 different combinations of the test results are applied to these two groups and presented in a table. The conclusion drawn is that in this particular group there is a decrease in prediction efficiency when a mental ability test is used, either alone or in combination with other tests.
