<p>Wellesley has a page</a> of statistics for the new class on its new website. A spreadsheet analysis shows some interesting numbers:</p>
<p>Class size: 636 (this is ~30-40 more students than usual, although it may still decline from continued "summer melt" through August.)</p>
<p>Acceptance rate: 33.8%
Yield: 44.3% (so far, see "Class Size")</p>
<p>Secondary Schools: 62% public, 34% private, 4% parochial, 0% home schooled.</p>
<p>Geographic Distribution: New England,21%; Mid-Atlantic, 16%; South, 16%; Central,13%; Pacific & Mountain,20%; International & Americans Abroad, 13%</p>
<p>Ethnicity: ALANA, 43%, White/Caucasian, 43%, International, 11%, Unknown/Not Reported/Other, ~3%</p>
<p>The page has a table of SAT score "bands" (750-800, 700-740, 650-690, etc.) showing, for each band, how many students applied, were accepted, and enrolled. This information is very interesting when additional analysis is applied. It seems that there is definitely a preference for admitting students who score in the highest reading bands, with 59% accepted in the 750-800 band, and 48% in the 700-740 band. Interestingly, this isn't the case with math where only 37% and 42% are admitted from the highest two bands, and the acceptance rate doesn't drop much in the lower bands to 600-640. There appears to be a lesser focus on students with high-achieving math scores, and a willingness to accept students with lower math SAT scores.</p>
<p>The most interesting story is the yield in these bands. While 27% and 39% of admitted students in the top 2 reading SAT bands (750-800, 700-740) enrolled, 39% and 51% of the top 2 math SAT bands enrolled. Although the school doesn't appear to be striving for the top math scoring students, those high-scoring math students seem to be selecting Wellesley after being accepted. Even more interesting, the yield in the next two bands is relatively high for accepted students with SAT reading scores of 650-690, 52%; 600-640, 58%. Students with lower reading SAT scores were more likely to enroll after being accepted than those with higher scores. However, in math yields fall off to 650-690, 39%; 600-640, 42%. Students with lower math SAT scores are less likely to enroll after acceptance than students with higher math scores. </p>
<p>The result is that (when officially published) the 25th percentile for math scores for the class of 2014 should be at least 750, and the 75th percentile should be at least 650. This appears to be a distinct change for the school, where class math SATs 25-75 percentile bands slightly lagged reading SAT scores. Perhaps it is the influence of having a scientist as the President of the school.</p>
<p>I hope this would be of interest to applicants. Comments?</p>
