<p>The class rank distribution (along with the % of students who submitted class rank) is presented in section C10 of the Common Data Set. Colleges can choose to make this information available or not. Brown, Wesleyan, Northwestern, and UPenn all make CDS files available on the Web with section C10 completed. BC apparently does not.</p>
<p>School … % in Top Tenth … % Submitting Rank
Brown … 93% … 37%
Wesleyan … 68% … 45%
NU … 90% … 43%
Penn … 96% … 100%</p>
<p>That last number (UPenn, 100% submitted) looks a little odd. I don’t know if that means they only admit students who report rank, or if they enter an estimate for those who don’t, or what.</p>
<p>Suffice it to say, students outside the top 10% seem to comprise a minority of the already small minority who are admitted. Multiply the percent-not-in-the-top-10% by the admit rate, and you could be down to low single digits (less than 1% for Brown & Penn).</p>
