<p>Regards to the study cited in the OP, my reaction is “Duh”. In almost all situations more information is better in evaluating something. A gpa of 3.7 from XYZ College gives you part of the puzzle. The courses on the transcript provide another piece. A GRE score of 2150 gives you yet another. And faculty LoR’s, yep another piece. And the students work/research experience rounds out the package. Take away any one and the evaluator has less information and has more difficulty in making a valid decision.</p>
<p>The one(perhaps minor) benefit of the GRE is that it eliminates instiutional biases and factors. Is the transcript influenced by grade inflation, is the LoR’s and research ginned up in any way?</p>
<p>And yes there are specific cases which mathmon and ek note which admissions people need to take into account, to the extent of even dismissing poor GRE scores altogether.</p>
