Full-time faculty and staff are required to be active members of a church of Christ. Attendance at daily chapel services (with a set number of allowed absences) is mandatory for all full-time students. OC operated Cascade College, a branch campus in Portland, Oregon, from 1994 until it closed in May 2009. Like OC, Cascade's full-time faculty and the majority of its students were members of Churches of Christ. In 1992, the Oklahoma Christian University Board of Trustees assumed the operation of the former Columbia Christian College after it suffered serious financial difficulties and lost accreditation. A year after Columbia closed, the new branch campus opened in 1994 as Cascade College. The North Central Association agreed that the accreditation of Oklahoma Christian, Oklahoma City, could extend to Cascade if close ties and supervision were maintained. In October 2008, the OC Board of Trustees announced that Cascade College would close after the spring 2009 semester. Bill Goad was the last president of Cascade and is now OC's executive vice president.
