<p>On things like class size, it’s much more reliable to look at the actual statistics, which are published in each college’s Common Data Set and can be quickly converted to presentation as a percentage of all class sections by size.</p>
<p>Princeton and Swarthmore do indeed have the same percentage of small classes (under 20), although Swarthmore’s tilts a bit more towards under 10 and this doesn’t include directed studies at Swarthmore that are one student/one professor.</p>
<p>Under 20 students:
73.5% Princeton
73.6% Swarthmore</p>
<p>This is logical. All schools have courses that simply don’t attract many students, especially as you move into the upper level electives for majors. These are never the types of courses where enrollment is an issue.</p>
<p>We start to see a divergence with the next group up, 20 - 30 students. These are “large” courses at Swarthmore – the intro science courses, etc. This is no-man’s land for Princeton, between the small course offerings and large courses:</p>
<p>**20 to 29 sudents **:
8.5% Princeton
19.3% Swarthmore</p>
<p>Both drop off in the next category:</p>
<p>30 to 39 students:
4.9% Princeton
3.9% Swarthmore</p>
<p>From there on up, the curves reverse themselves:</p>
<p>50+ students:
10.7% Princeton
2.2% Swarthmore</p>
<p>One out of every ten courses taught at Princeton is a lecture class of 50 or more students. So, these anecdotal stories of completing 32 courses at Princeton without ever taking one aren’t terribly plausible, on average.</p>
<p>Keep in mind that the large classes have a disprorpotionate impact on student experience. For example, it takes ten class sections of ten students to give 100 students a small course experience, but just one class section of 100 to give the same number of students a large lecture course experience. The stats would look very different if you measured as a percentage of student/courses taken rather than as percetage of courses offered.</p>
<p>BTW, Yale has slightly fewer large classes than Princeton does…but, both probably set the bar for research universities. In other words, for a college to have smaller classes than Princeton (with its per student endowment) is saying a lot.</p>
