<p>You beat me to it–this is exactly the case, even at schools that are outside the top. </p>
<p>I heard from a colleague at a school ranked between 60 and 75 who said that only 40% of their enrollees came from a school which supplied class rank. They were trying to figure out what to do about reporting. </p>
<p>Another colleague at a top public school told me that they did their own calculation (based on some data complications they couldn’t get around) and had less than complete faith in its accuracy.</p>
<p>These are just anecdotes but it’s not speculation–these are higher ed professionals who generate the numbers that go into the CDS and USNews.</p>
