Equivalence of forms of the Wonderlic Personnel Test: a study of reliability and interchangeability

Abstract

In a replicated 5 X 5 Latin square design, the 5 forms of the Wonderlic were administered in 5 orders to 14 sets of 5 subjects. "The Wonderlic forms vary in level of difficulty and cannot be regarded as equivalent and interchangeable… the forms appear also to vary in reliability."
