Let’s discus admissions data for the class of 2021. Key table:

Today is Day 1.

The data is derived from the early decision news release, the regular decision news release and the 2016-2017 Common Data Set (pdf).

From the latest news release:

Of the [1,253] admitted students, 95 are international students representing 47 different nationalities. Among American students, 50 percent identify as students of color: 220 students are Asian American, 214 are black, 175 Latino, and 17 Native American. Thirty-seven percent identify as white and five percent opted not to identify. A total of 274, or 22 percent, are first-generation college students, and seven percent (86) have a parent who attended Williams.

Note that all these numbers include the 257 students admitted via Early Decision in December. So, Williams only accepted 996 students via regular decision: 1,253 – 257 = 996.

Caveats: This is the first time I have attempted an analysis like this. Mistakes are likely! In particular, I did lots of algebra in my head and made some simplifying assumptions. The “Projected Yield” is the percentage of admitted students in each category which would need to enroll in order to match the totals for the class of 2020.

That 700 admitted students turn us down — overwhelmingly for schools like Harvard/Yale/Princeton/Stanford and significantly for the next tier (Dartmouth/Brown/Amherst/Swarthmore) — is a sign of the gap we face in becoming the best college in the world. We need more of these high quality students to choose Williams.

Among students that both we and HYPS accept, we yield only 10% or so. Of course, many of those students are making the right choice when they turn down Williams. Anyone who hates the snow would be happier at Stanford. But many (10%? 25%, 50%?) of the students who turn us down are making a mistake. They would have been happier at Williams. We need to do a better job of selling Williams to them. Suggestions?
