Overview
The GMAT exam has been shown to be a reliable indicator of academic potential for graduate management study. By reliable, we mean that randomly selected test takers would perform similarly over repeated testings. But, in practice, who sits for the test over and over again? And why? And how do they perform? The GMAT exam is given more than a quarter of a million times each year, and approximately a fifth of those tests are being taken by people who have taken the exam before. Although there are no meaningful differences in the gender, average Quantitative scores, and undergraduate GPAs among repeat test takers, there are some other key differences between those who choose to retake the exam and those who don’t. This article explores these differences.
