Hi there,
As Jon mentioned, it depends on the industry. For some of the more discerning ones, it's mandatory. As jontron correctly mentioned, your score should be at least mid 90s in percentile, right (this holds true for the GRE too)? In that case, at the bottom of your resume where you have your education component, it wouldn't hurt to use one bullet (either full horizontal or half a column if split in 2) where you say "GRE | 9Xth percentile".
It is merely another data point and it's one worth showing off. However, it keeps it off the main part of the resume and if they read through the whole thing, it can act as a differentiator.
However, the point in that is the top half of your resume needs to convert the reader and make them read the other half. That way, if they think you're in contention, that might stand out to them. However, if the first half doesn't, then you haven't wasted time telling them a standardized test score and put your best material forward.
Does that make sense?
