<p>To be fair:</p>
<ol>
<li> It’s misleading to compare graduation rates and middle-50 SAT ranges between the University of Iowa and Grinnell. Iowa has over 21,000 undergraduates, Grinnell fewer than 1,700. You could easily two colleges statistically identical to Grinnell out of Iowa’s top 25% (and have a couple of colleges not equivalent to Grinnell left over). And it’s a wild guess, but I’ll make it anyway: I bet the graduation rate (however you measure it), of those two Grinnell-equivalents buried within Iowa are not far off what you see at Grinnell.</li>
</ol>
<p>Iowa, and other public universities, especially state flagships, do pretty much everything that Grinnell does, and a whole lot more. They give a huge number of students with a wide variety of natural gifts, backgrounds, and secondary educations a real opportunity for an excellent college education. They don’t limit the entering class to those most likely to succeed from the get-go. So of course their overall numbers are not as good as Grinnell’s, but in large part that’s because Grinnell’s admissions department (and overall design) limited its risks to a very large extent. (And, yes, I know Grinnell does a great job with students from disadvantaged backgrounds, but I think that reflects, in large part, cherrypicking students in that population. I don’t know any such students at Grinnell, but I know some at other, similar LACs, and they are stone sure-bet winners. The riskier kids are at public universities.</p>
<ol>
<li> Carleton (like other top LACs) offers a wide range of majors. But when you look at the depth of offerings in each, there can be real issues. The Carleton Linguistics Department, for example, consists of three people. (Which is actually great for a LAC Linguistics Department.) Majoring in Linguistics there effectively means getting tutored by them. That’s not necessarily a terrible model for how to get educated.<br></li>
</ol>
<p>But contrast it with, say, Penn, generally regarded as a strong (but not the strongest) program: 19 full-time faculty, 3 emeriti, 8 associated faculty from other fields (psychology, anthropology, etc.). In a field where there are a lot of sub-fields that don’t overlap much, all of the sub-fields are covered at least a couple people deep. Plus, there are 30 grad students, some of whom know a heck of a lot, and a steady stream of people giving job talks, guest lectures, etc. </p>
<p>The two environments are really not comparable; Penn’s is so much richer. But when a linguistics major leaves Carleton, he or she will probably have sucked at least one of its faculty pretty much dry, and at Penn there’s no guarantee that any faculty member will take personal responsibility for making certain that a particular undergraduate really has a solid base of knowledge.</p>
