| Research into factors that contribute to student success have used undergraduate grade point average (GPA) as the dependent variable. However, undergraduate GPA is subject to grade inflation and to differences in institutional and program rigor. To provide a common benchmark across institutions and programs, this study used the Graduate Management Admission Test (GMAT) composite score as the dependent variable. Astin's Input-Environment-Outcome (I-E-O) model was used as the conceptual framework. Correlation analysis and a blocked form of stepwise regression were used to partial out the impact of 107 variables arrived at from the national Higher Education Research Institute's Freshman and College Senior Surveys on the dependent variable---GMAT composite scores. In all, 10 variables were identified as having a significant influence on student performance on the GMAT, with Scholastic Assessment Test math and verbal scores and institutional Selectivity having the greatest influence. While prior studies have attempted to use a variety of standardized tests, previous research did not account for prior student academic abilities and other input characteristics to accurately assess the added value of other variables. This study offers new, useful information for educators and administrators in their goal of promoting academic excellence. |
