The Washington Monthly, a noted public affairs magazine, ranks colleges based on the colleges' contributions to the public good in three areas: contributions to social mobility (recruiting and graduating low-income students), research (producing scholarship and having students move onto PhDs), and service (encouraging students to give something back to their country). You can see all of the rankings and the indicators that the Monthly used in producing its rankings here.
Puget Sound is ranked 72nd of 250 liberal arts colleges on the list.
