The journal Science has recently published a meta-analysis of numerous long-term studies examining the correlation between high GRE scores and the quality of work done by graduate students once they are enrolled in doctoral (and in some cases) master degree programs. The researchers--professors of Education at several universities have included there is no evidence that there is a relationship between a high GRE score and "successful" work in grad school; in this case, successful means contributing meaningful, thoughtful, and original work in response to assignments, whether they be short research projects or doctoral dissertations. Another study, in fact, has found a correlation between receiving high scores on the GRE and doing poorly in certain fields of study. This may seem counter-intuitive, but then, so many things are. I'm not including a link for time limitation reasons, but the study would be easy to track down and read if you insert the appropriate descriptors in a search engine. What will this research do in terms of the status of requiring that grad school applicants submit GRE scores? In the short term, I doubt whether it will change much of anything.
