<p>I did the calculations, their new acceptance rate should be about 13~15%. They usually have a 33% yield rate, and they accepted ~800/~2400 students ED (source: [Applications</a> Hit New High : Northwestern University Newscenter](<a href=“http://www.northwestern.edu/newscenter/stories/2012/01/applications-new-high.html]Applications”>Applications Hit New High - Northwestern Now)), thus they only need to fill out 1200 RD. Thus, based on their yield rate, they have to accept about ~3600 RD kids. Based on both regular and early admission, their acceptance has most likely fallen a good amount.</p>
<p>Also, the administration is now looking to accept more ED kids, because they want a lot more people who have NU as their first choice (driving retention up and RD acceptance down). That and I also heard a rumor that NU was looking to reduce the class size this year because of something (assuming renovations and such)–this is just a rumor though, so who knows…</p>
