<p>ID - your point about class size would make sense if it were purely a function of Swat having more teachers than Wes. But a student/faculty ratio of 8:1 is not, pedagogically speaking, all that big an advantage over Wesleyan’s 9:1 ratio; it certainly wouldn’t account for a 20% difference in expenditure per student. I think the real culprit here is simple economy of scale: if you look at the expenditure rates for some of the better research unis (if you can somehow separate out their medical schools) you will find that Wes is somewhere between a lower Ivy and Swat, which is about where you would expect a school of 2,600 to be.</p>
