What are colleges that put kids into houses? (like Yale, Harvard, Franklin and Marshall)
Do you mean architecturally, socially, educationally or all of the above?
There are a number or schools that have “residential colleges,” similar to the Oxford/Cambridge model wherein you belong to a residential college that is part of a larger university. Schools that come to mind are Harvard, Yale, Princeton, U Penn, Rice, and UCSD; some may even physically resemble Hogwarts architecturally (certainly UCSD doesn’t fall into that category).
Here’s a link to a bunch of schools with residential colleges worldwide:
Northwestern has Res Colleges - and also the Deering Library - which has a “Hogwarts-like” look and feel to it

Side Note - I am a B1G fan of Res Colleges - At Graduation today, my son wanted pictures taken with his closest friends - and they were all from his Res College.
@LoveTheBard This site is perfect! Thank you!
I’m not entirely sure that this is what you mean, but Smith has houses instead of dorms, and “house life” seems to be a pretty big part of the school’s culture. Also, Vassar’s dorms are called houses (though they are still dorm-sized); they are all somewhat distinctive and incoming freshmen are placed into houses using a “sorting hat.”
Notre Dame is one.
House systems tend be more common at larger schools because they may be needed to encourage the small scale social interaction which might not otherwise occur. Smaller colleges may serve as “houses” in and of themselves, in that their lower enrollments often make them naturally unified. However, smaller schools sometimes offer programs that integrate the residential and classroom evironments for students who elect the option. Hamilton offers REAL, for example.
The University of Oklahoma will have residential colleges beginning in the fall of 2017. http://www.ou.edu/content/residentialcolleges.html
Does WUSTL have something like this? I thought I read that somewhere but I never really looked at the school all that closely.
UChicago
Good question, I wondered about the differences between house systems at the different schools.
I have heard Yale students strongly identify with their house and everyone believes their house is the best. Do students at the other schools mentioned feel as strongly about their house affiliation?
Vanderbilt has first year students placed into houses/dorms on the freshman commons. They even have competitions (i.e. soccer games, academic competitions, debates) to earn points for the house cup at the end of the year. Tour guides said that everyone still feels a strong connection to their house after they leave. Vanderbilt also has college halls as mentioned in the list posted by LoveTheBard for students after freshman year. http://www.vanderbilt.edu/collegehalls/
Vassar and Chicago
@nw2this At UCSD, people are generally more spirited re their college than the university as a whole, and everyone definitely believes their college is the best (except Sixth. Sixth is awful.)
