Over- and underachievement and the Edwards Personal Preference Schedule

Abstract

Does the Edwards Personal Preference Schedule differentiate between under- and overachievers? How does an aptitude test battery compare with 3 achievement tests and high school standing as a basis for determining over and underachievement? "Two samples, each consisting of 120 Ss were selected; the samples were termed aptitude-based and performance-based. 73 Ss were in both samples.... there were 20 Ss [college freshmen] at each of three levels of expected performance for both over- and underachievement groups." Differences between groups were found according to the Edwards. "For the purposes of selection, the EPPS and certain evidences of past performance are functionally equivalent."
