The effects of a second administration of an employment test

Abstract

The records for 230 applicants who took the L.O.M.A. employment test twice indicate a mean increase of second score over first of 12 points, individual changes ranging from 62 to -18. Persons taking the same form of the test obtained significantly higher increases than those taking different forms, the mean differences being 16 and 8. The r between score change and time between tests was .03. Data are presented to show that there are serious distortions in the percents exceeding various critical scores when the second score is used. Persons employed after the second test obtained higher scores on first test and greater increases on second test than did persons refused employment. The employment records of 19 persons scoring under 100 on first test and over 100 on second test show them to have been less successful than persons scoring over 100 on first test.
