SIOUX FALLS, S.D. (AP) - Colorado Technical University is closing its campus in South Dakota's largest city within four years.

Officials cite falling enrollment as a reason for shutting down the Sioux Falls location. The for-profit school stopped enrolling students Wednesday and said it would give current students a reasonable amount of time to complete their studies. Officials expect the campus to remain open through September 2016.

Campus President David Heflin says the closing will affect about 100 staff members. He says transferring to other campuses will be an option for some staff.

Colorado Tech also has campuses in the Colorado cities of Colorado Springs, Denver and Pueblo, as well as in Kansas City, Mo. The school plans to close the branch in Pueblo. University services will be available after September 2016 through the Internet.
