Oglethorpe University is one of the nation’s Best Liberal Arts Colleges, according to the annual U.S. News & World Report Best Colleges Rankings.

Last year, U.S. News added a social mobility ranking, and Oglethorpe is once again one of the best performing liberal arts schools in the country in that category. Social mobility measures the economic diversity of the student body by looking at Pell Grant recipient graduation rates. Oglethorpe ranked in the top 25 in the category on a campus where 42% of students are Pell-eligible.

Oglethorpe also ranked as the 13th most diverse student body among liberal arts colleges nationwide. U.S. News measures ethnic diversity to “identify where students are most likely to encounter undergraduates from racial or ethnic groups different from their own.”

Universities nationwide are rated annually by U.S. News in an effort to help prospective students and their families evaluate higher education choices. Schools are ranked according to their performance across a set of widely accepted indicators of excellence and key weighted measures of quality: graduation and retention rates; assessment of excellence; faculty resources; student selectivity; financial resources; graduation rate performance; and alumni giving.

The country’s liberal arts colleges emphasize undergraduate education and award at least half of their degrees in the arts and sciences, which include such disciplines as English, the biological and physical sciences, history, foreign languages, and the visual and performing arts but exclude professional disciplines such as business, education, and nursing.
