You have a number of the Colleges That Change Lives schools on your list, so I’m assuming you’ve seen it, but if not, you may want to take a look there: College Profiles – Colleges That Change Lives
I’ve never visited Beloit or Agnes Scott and thus don’t have a good sense of their vibes. I think that Clark, which has been mentioned several times, would be worth investigating. Other possibilities might be:
Evergreen State College (WA)
Goucher (MD)
Hiram (OH)
Kalamazoo (MI)
McDaniel (MD)
If Earlham is a possibilty (which is a Quaker school), then you may also want to consider Guilford (NC).
@Sweetgum had a kid who really liked Agnes Scott and may have some familiarity with some other schools that your child might like.
ETA: Oh, and what about Lawrence (WI)?
