The "Washington Monthly"s "College Rankings" began as a research report in 2005. Related rankings appeared in the September 2006 issue. It offers American university and college rankings based upon how well each enhances social mobility, fosters scientific and humanistic research and promotes an ethic of service. Washington Monthly puts the colleges in four separate categories based on whether they offer master's degrees, doctoral degrees, or only bachelor's degrees, and the extent to which these respective degree types are offered. In their Baccalaureate College category their top five are: Elizabeth City State University, Tuskegee University, Bethel College-North Newton, Wheeling Jesuit University, and Messiah College. In their Liberal Arts Colleges category their top five are: Bryn Mawr, Carleton College, Berea College, Swarthmore College, and Harvey Mudd. In their Master's Universities category their top five are: Creighton, Truman State, Valparaiso, Trinity University, and SUNY Geneseo. In their National Universities category their top five are: UC San Diego, UC Riverside, UC Berkeley, Texas A&M, and UCLA.
