Recently Educational Testing Service (ETS) published a GRE comparison tool to show students how they may score on the GMAT given their GRE scores, however this week the Graduate Management Admissions Council, (GMAC) creators of the GMAT, spoke out against the tool.
“This GRE comparison tool is not as precise at it may appear, and using it is not as straightforward as presented” warned the GMAC article. “The comparison tool is about averages. Admission decisions are about individuals”"
GMAC goes on to point out that ETS themselves admit to a large standard error of prediction – 67.4%. This means that there is only a 17.6% probability that the predicated score would be the same, or within a range of plus or minus 10 points. Probability favours a much higher or lower actual score then calculated with the GRE comparison tool.
“The GRE and GMAT exams are different tests, measuring different content. No conversion table will ever make them equivalent” GMAC cautions. “The best way to predict a GMAT score is to use the GMAT exam“.
