<p>Note that all schools need to predict yield based on characteristics of admitted students in order to admit the correct number of students to fill the spaces in the incoming class, but only some schools are actively trying to raise their overall yield rates though “level of applicant’s interest” games. (E.g. the admit-by-formula schools obviously do not do the latter, even though they do the former in setting the threshold based on expected yield of admitted students.)</p>

<p>Since HYS (and P) have SCEA/REA which precludes the student from applying to potential cross-admit-competitive schools EA or ED, applying SCEA/REA there likely is an expression of “interest” that correlates to a higher yield rate than an RD application (even if it is not a criterion for admission).</p>
