Current Nonverbal Assessment Instruments: A Comparison of Psychometric Integrity and Test Fairness

This paper is a review of new and newly revised nonverbal tests of ability. Five nonverbal instruments were compared with regard to psychometric integrity and indications of test fairness. This comparison revealed that although the instruments examined are generally impressive in terms of technical adequacy and sensitivity of administration guidelines, they tend to present less statistical evidence of test fairness. Findings are discussed with regard to implications for users of nonverbal assessment instruments.
