<p>The 80% yield on EA acceptees is a little less surprising in light of the fact that Yale’s overall yield was over 70%. The yield on RD acceptees would have been about 65%. (Only a tiny handful of private colleges have RD yields over 50%.) All it would take to equate the two would be for about 140 of the SCEA admitted students to decide to treat it as ED and not to apply elsewhere. Based on what I’ve seen in the cases I know, that seems pretty likely.</p>
