After ETS has made some significant inroads into GMAT market share with its own GRE over the past year, GMAC is now hitting back with an article on its site that debunks ETS's GRE Comparison Tool for Business Schools.
"This GRE comparison tool is not as precise at it may appear, and using it is not as straightforward as presented. The comparison tool is about averages. Admission decisions are about individuals," argues GMAC in the article on its site.
GMAC's argument against the tool was primarily a statistical one:
"As a specific example, for a GRE verbal score of 660 and quantitative score of 670, the tool would predict a GMAT Total score of 650. In this case, 1 in 4 people with this predicted score would actually earn 600 or below if they were to take the GMAT exam. In addition to prediction error, there is also measurement error in both the verbal and quantitative GRE scores, so the chance that this individual would actually score something close to 650 is extremely thin."
Going further, GMAC then raises the question of whether comparing students with actual GMAT scores to those with predicted scores is fair: "To use predicted GMAT scores along with actual ones unfairly penalizes both sets of test takers, because applicants with valid GMAT scores could be displaced by applicants with predicted scores that are much too high."
Interestingly, ETS launched the GRE Comparison Tool GRE® Comparison Tool at www.ets.org/gre/comparison about a year ago, but now that web address redirects to a promotion encouraging business schools to start accepting the GRE. Maybe GMAC was able to apply enough pressure to get ETS to remove the tool? Maybe ETS decided it needs to go back to the drawing board?
While we expect that the GRE is here to stay in the graduate management education admissions business, we agree with GMAC that the GMAT is still the most proven measure of the skills an MBA applicant needs to succeed in the classroom. If you're thinking about grad degrees and general and are only somewhat interested in earning an MBA, then perhaps the GRE is the better place to start. If you're sure that a top-tier MBA is what you want, however, the GMAT is your best bet.
