<p>I'm interested in information that members of the CC board may have on ED across the country this year (and for the coming year). Has anyone learned of changes in ED policy at the LACs or otherwise? Williams, for example, has stated that its ED acceptance rate will stand at no more than 30% from the class of 2007 and afterwards. Is there a shift underway (apart from the move to single-choice early action) among the schools that will stick with the traditional ED? </p>
<p>In the absence of any statements of policy, one of the ways to measure the effect that early decision has at any given school would be to look at the difference between acceptance rates for RD and ED and, thereafter, the change in differential over the years. For example, take the numbers that I have for Haverford from the Common Data set for the incoming classes of 2003 and 2004. In 2003, the ED acceptance rate was 51% and the non-ED rate was 28%. Setting aside the populations of both pools for the moment, and the self-selection bias at work for most of these schools, the differential (i.e., 23%) for 2003 at Haverford suggests that ED helps. However, the ED acceptance rate dropped to 47% there this year. There were similar drops at other schools, although the data can be hard to come by for this year at least. </p>
<p>I have read The Early Admissions Game (Avery, Fairbanks and Zeckhauser), so I understand the data for particular schools and the general conclusions offered by those authors ("[E]arly applicants were much more likely to be admitted than regular applicants with the same qualifications." (150)).</p>
<p>Can anyone offer more recent data, policy statements, or anecdotal evidence about what's going on with ED these days? Thanks much.</p>
