So I was looking at Washu Common Data Set https://wustl.edu/about/compliance-policies/registrar/student-consumer-information/ and I noticed that between each year that WashU accepted waitlisted students, they accepted 0 waitlisted students.
For example:
2015-2016: 129 waitlist accepted
2014-2015: 0
2013-2014: 80
2012-2013: 0
2011-2012: 152
2010-2011: 0
What’s up with that?
