<p>The College Board posts the cdf of the scores (the percentiles) on their website:</p>
<p><a href=“http://www.ets.org/Media/Tests/GRE/pdf/gre_0809_guide.pdf[/url]”>http://www.ets.org/Media/Tests/GRE/pdf/gre_0809_guide.pdf</a></p>
<p>They list the cdfs on page 13, which puts 80% around 570V, 730Q, 5.0AW.</p>
<p>These number matter very little in actual applications, however, because different fields have very different distributions - for engineers, a 730Q is low but a 570V is decent. Conversely, English majors would be thrilled to get a 730Q and would be in real trouble with a 570V. Pages 17-19 show median scores by intended graduate field, for reference.</p>
<p>The best way to interpret your GRE scores is to go to the department (the one to which you are applying) website and look at their mean or “25%/75%” scores. If your scores are lower, ask yourself what else you have on your app that will outshine the rest, and if they are higher, ask whether or not it is enough to cover any weak spots you have elsewhere.</p>
