The GMAT as a Predictor of B-School Performance Among U.S. Students

In an effort to continually assess the validity of the GMAT® (alone and in combination with undergraduate grade point average) as a predictor of business school students’ performance in their core courses, the Graduate Management Admission Council® (GMAC®) conducts validity studies on its own behalf and on behalf of schools who request a study through the Validity Study Service.

GMAC recently conducted a study to find out whether the GMAT is—

  • valid as a predictor of performance;
  • as effective a predictor for underrepresented U.S. minority students as for students generally;
  • biased in any way.

In order to find schools to participate in the study, GMAC analyzed where underrepresented minority test-takers were sending their GMAT scores and identified the full-time, part-time, and executive MBA programs that received the most such scores. These programs were invited to participate in the minority validity study, which compared the predictive validity of the GMAT for all major U.S. subgroups. Eleven full-time programs, seven part-time programs, and five executive MBA programs participated in the study.

The data from the 3,175 U.S. students in full-time programs were analyzed and recently presented at the 2003 GMAC Annual Industry Conference (the data from the other programs will be analyzed in the coming months). The study found that the GMAT is a valid predictor of core-course performance for all U.S. subgroups, that it has similar predictive validity among all U.S. subgroups, and that the test has no measurable biases.

For more information about this study and to request a validity study for your school or program through the Validity Study Service, please contact Susan Swayze, GMAC director of research, at swayze@gmac.com.
