Declining American competitiveness in world economic markets has renewed interest in employment testing as a way of putting the right workers in the right jobs. A new study of the U.S. Department of Labor's General Aptitude Test Battery (GATB) Referral System sheds light on key questions for America's employers: How well does the GATB predict job success? Are there scientific justifications for adjusting minority test scores? Will increased use of the GATB result in substantial increases in productivity? Fairness in Employment Testing evaluates both the validity generalization techniques used to justify the use of the GATB across the spectrum of U.S. jobs and the policy of adjusting test scores to promote equal opportunity.
