i am so sorry, the GRE is still a valid tool in graduate admissions
A recent Atlantic article by Victoria Clayton makes the case that the GRE should be ditched based on some new research. The case for the GRE rests on the following:
- The GRE does actually, if modestly, predict early graduate school grades and you need to do well in courses to get the degree.
- Many other methods of evaluating graduate school applications are garbage. For example, nearly all research on letters of recommendation shows that they do not predict performance.
To reiterate: nobody says GRE scores are perfect predictor. I also believe that their predictive ability is lower for some groups. But the point is not perfection. Th point is that the GRE sorta, kinda works and the alternatives do not work
So what is the new evidence? Actually, the evidence is lame in some cases. For example, Clayton cites a 1997 Cornell study claiming that GRE’s don’t correlate with success. True, but if you actually read the research on GRE’s there have been meta-analyses that compile data from multiple studies and find that the GRE does actually predict performance. This study compiles data from over 1,700 samples and shows that, yes, GRE does predict performance. Sorry, it just does, test haters.
Clayton also cites a Nature column by Miller and Stassun that correctly laments the fact that standardized tests sometimes miss good students, especially minorities. As I pointed out above, no one claims the GRE makes perfect predictions. Only that the correlation is there and that is better than the alternatives that simply don’t predict performance. But at least Miller and Stassun offer a new alternative – in depth interviews. Miller and Stassun cite a study of 67 graduate students at Fisk and Vanderbilt selected via this method and note that their projected (not actual) completion rate is 80% – much better than the typical 50% of most grad programs.
Two comments: 1. I am intrigued. If the results can be replicated in other places, I would be thrilled. But so far, we have one (promising) study of a single program. Let’s see more. 2. I am still not about to ditch GRE’s because I am not persuaded that academia is ready to implement a very intensive in-depth interview admissions system as its primary selection mechanism. The Miller and Stassun column refers to a study of physics graduate students – small numbers. What is realistic for grad programs with many applicants is that you need to screen people for interviews and that screen will include, you guessed it, standardized tests.
Bottom line: The GRE is far from perfect but it is usable. There is no evidence to systematically undermine that claim. Some alternatives don’t work and the new proposed method, in depth interviews, will probably need to be coupled with GREs.
