Is there research that provides evidence that GRE scores are predictive of success in business school?
A meta-analysis, conducted by Nathan Kuncel and his colleagues (Kuncel, 2001), included over 80,000 students in over 1,700 independent validity studies. This research demonstrated that the GRE General Test has excellent predictive validity for social science programs, including business.
