Published Article / The Council on Higher Education (CHE) (2004) states that graduation rates across all provider types of MBA qualifications in South Africa are not very high. Various studies have reported that, in order to address poor throughput rates, one of the important aspects that needs to be addressed, is the criteria used to select students. The purpose of this study was to identify valid predictors and measures of the academic performance of MBA students. Multiple regression analysis was used to determine the significance of different competencies and aptitudes in predicting academic success. The sample consisted of 135 MBA students from a South African School of Management. The results show that certain aptitudes and competencies, namely numerical aptitude, personal motivation, verbal aptitude, and resilience, contributed statistically significant to academic success.
