I've rattled off class size statistics for years. 47% of classes have less than 20 students, 84% have less than 50, 7% have more than 100. The overall student to faculty ratio is 15:1. I've never seen school-specific statistics and these numbers, though.
Today, we got some statistics that dealt specifically with the College of Arts & Sciences, which enrolls 74% of UVa students.
The student to faculty ratio is 17:1, but this includes graduate and undergraduate students. Our assessment office was not able to break that down, which makes me think the overall ratio might also include graduate students.
The average class size in the College is 33 students. The median class size is 17.
I don't like to throw statistics around when it comes to admission because I think people sometimes try to over analyze them (our average SAT score really isn't going to tell you much about UVa). I think class size statistics are interesting, though.
