Validity of GMAT
Validity refers to how well the GMAT exam does what it is intended to do—predict students’ academic performance in the core courses of a graduate management or business program.
The GMAT is the first and only test designed to predict student performance in business school, and it does so more reliably than any other known measures, including the Graduate Record Examination (GRE) and other standardized assessments.
For 50 years, GMAC has maintained the reputation of the GMAT exam as the best assessment for business school admissions by continually studying the performance of test scores as a predictor of academic performance to ensure the test’s validity.
