<p>ses,
I agree with your point about the advantages of small classes, but I think you may be missing how closely the USNWR Top 20 National Unis compare to the USNWR Top 20 LACs for both class size and student/faculty ratio. Both groups of schools offer 69% of their classes in sizes of 20 or fewer students while the Nat'l Unis even have an advantage in student faculty ratio (7.2/1 vs 8.8/1 for the LACs). Here is the full list:</p>

<p>By contrast, the five most highly ranked public universities have a student/faculty ratio of 15/1 and 51% of their classes to groups of 20 or fewer. This is obviously one of the major differences between the privates and the publics.</p>
