The Killeen Adventist Junior Academy was established in 1971. The acreage that the school sits upon was bought in 1969 with the intention that the Killeen Seventh-day Adventist Church would be built on it. The two acres were developed and after much prayer, the church members decided to build a church school instead. School was scheduled to begin on the 9th of September 1971. Despite the long hours, the school wasn't ready. A member of the church, Bonnie House, cleaned out her old barn on 60th St. and the first day of school was started. By January 1972, the school was habitable and school started on Lake Road. In 1982 the plans for building the gym began, spear-headed by Dr. Gohl, to complete the school you see today.
