Meaningful Academics

The liberal arts remain the foundation of a great education for all FMU students, but we’ve developed an array of professional programs to meet the 21st century needs of both our students and our community.

The Right Size

The University keeps class sizes small because that’s the environment that best facilitates learning. A 15:1 student-professor ratio, and a student enrollment of 4,000 provides the perfect balance to enhance learning and still promote a diverse selection of programs.


Students can walk our lovely, tree-lined campus in about 30-45 minutes, but most take longer because in a place this beautiful, you want to stop and enjoy nature’s beauty.


Francis Marion University has been recognized for six straight years as a “Great College to Work For” Honor Roll university. Read more here.

Francis Marion University is ranked among Washington Monthly’s “Best Masters Universities” in the magazine’s latest ranking.

  • FMU is consistently ranked among the Best Regional Universities by U.S. News and World Report.
  • Francis Marion University is listed as the Best Ethnically Diverse University in the South by U.S. News and World Report.
