<p>I don’t think the OP is necessarily talking about retention rates, but rather colleges where kids want learn, and are not just in college to get a better job or because of pressure from their parents/society.</p>
<p>In this case i would recommend colleges like Swarthmore, Chicago, and Reed. Most selective colleges would fit this description though, in that most kids who worked hard enough in high school to get into these colleges actually like school.</p>
<p>I do not think Iowa fits OP’s description, I mean I am sure its a fine school, but OP is not talking about the schools as much as he is the student bodies.</p>
