<p>Back in the day (including not so long ago, and maybe still), GCs at the feeder high schools used to be a big help in the yield management department. In the first place, they did a lot to make certain that all of the great students weren’t competing with one another for the same colleges, and that lots of students were taken ED by their first choices, so came off the market altogether. If asked, they would generally give an indication of how likely a student was to enroll if accepted, and they were pretty adept at making their predictions come true if necessary.</p>
<p>As a result, I doubt anyone ever accepted 15 kids per year from Exeter repeatedly only to have few or none of them enroll (unless it was a college where that was par for the course). The college advisers there wouldn’t let it happen.</p>
