SWIC has campuses in Belleville, Granite City and Red Bud. The college also has an office and classes on Scott Air Force Base and at East St. Louis Community College Center. Courses are offered at various venues throughout the district, such as high schools and libraries. With online learning, students can take some courses without the constraint of a physical location. In keeping with the mission of life-long learning, SWIC operates the partially grant-funded Programs and Services for Older Persons program.
