Demystifying the GMAT: Guarding Against Bias

July 31, 2012


Today, slightly more than half of GMAT test takers are non-US citizens, and we at GMAC recognize the importance of providing a test that is fair, valid, and reliable for all test takers, regardless of their native language. A fair and reliable test means that all individuals of the same ability should get the same scores. It does not suggest that the averages by native language should be approximately equal. Different groups are expected to have different sets of skills, and within any group, there is also a self-selection bias. This article discusses some of the many ways that our test developers guard against bias in the GMAT exam under these conditions.
