<p>The elimination of Early Decision was an institutional initiative to create a more equitable admissions picture with the single-date deadline. Students with more advantaged backgrounds disproportionately took advantage of the option, which tended to excessively work against the favor of those less advantaged backgrounds. The classes of 2012, 2013, 2014, and 2015 entered/will enter under the lone-date deadline, but Harvard explicitly stated in its press release published at the commencement of the practice that it would reconsider early admissions (in one of its varieties) for the sake of preserving the overall caliber of its student body after a brief pilot run.</p>
<p>I feel that Early Decision is almost certainly a vestige of the past for Harvard, though Early Action and Single-Choice Early Action remain potential candidates. The latter would perhaps being the most likely if it decides to reinstitute the procedure.</p>
