College of Southern Idaho is a public community college in Twin Falls, Idaho, United States, with outreach programs in Boise, Hailey, Burley and Gooding.
College of Southern Idaho offers associate of arts, associate of science, associate of applied science degrees and technical certificates in over 115 disciplines. Additional upper-division courses through the University of Idaho, Idaho State University and Boise State University are also offered. Credits transfer from CSI to these other Idaho schools very easily, so transferring is a smooth transition.
CSI's enrollment is approximately 7,000 students with an additional 3,000 in non-credit courses. Approximately 85% of the student body is from Idaho's Magic Valley region. The college is governed by a five-member Board of Trustees elected at large by voters in Twin Falls and Jerome Counties.
Until the foundation of the College of Western Idaho in 2007, CSI was one of only two comprehensive community colleges in Idaho, along with North Idaho College in Coeur d'Alene.
