Oklahoma Christian School, originally known as the "Christian Center School", was founded in Fall 1970 and operated as an arm of the Christian Conquest Center Church in Oklahoma City. During the 1974-75 school year, the church decided to terminate the operation of the school as an arm of the church. Interested parents and teachers decided that the school must continue. The reorganized, independent school was incorporated as Oklahoma Christian Schools, Inc. on January 13, 1975. Thirteen seniors composed the Class of 1976, the school's first. In 1987, OCS moved to the MetroChurch campus in east Edmond, Oklahoma. After renting facilities for approximately 20 years, OCS completed its first major building project in 1991-92. It included a gym complex, with eight new classrooms added in 1995. The facility also houses a band room, science laboratories and the middle school administrative offices. In 2000, after MetroChurch merged with Life Church, the school began to convert church facilities to fully functional educational facilities. OCS completed its multi-purpose Student Center at the end of the 2007-2008 school year. This building, the first phase in OCS's campus expansion, houses a cafeteria, band room, classrooms, concession stand, football locker rooms, and a secondary gymnasium. The OCS Master Plan includes a long-term expansion plan that will eventually move OCS out of many of its present buildings into new facilities.
Chapel
OCS has a chapel program under the leadership of the chapel council—class chaplains and the STUCO Chaplain. This is a time of student-led worship, Bible reading, and messages either from administrators or outside speakers. It is not a non-denominational time, but rather an inter-denominational time in which students from all denominations are equally respected. Chapel is traditionally held every Wednesday, and classes on that day are each shortened to make time for the event.
HEROES Week
OCS students and faculty of all grades reserve one week of every school year to raise money for a charitable cause. HEROES stands for Hands Extended Reflecting Our Exalted Savior. Recipients have ranged from OCS students to families outside the student body to Westwood Elementary School in Oklahoma City to the No Boundaries International Missions Group in Sierra Leone, Africa. This week consists of many events such as movie night, a date auction, flamingo football, and teacher auction. The largest grossing item to date is a seven-course homemade gourmet Italian dinner that collected over $300 a plate. At the end of the week, the school assembles in an all-school chapel assembly, and after worship songs and scripture readings, the check is presented to the families or the organization representative.
Robotics team
OCS is also home to FIRST Robotics Competition team number 3169. The "Saint-Borgs" have been competing for 3 seasons. Their latest robot, Hellen Kepler, performed in the semifinals of Rebound Rumble at the Oklahoma City regional competition. The OCS and team mascot is not a saint but a stick named Buzz, named after Buzz Aldrin.
