A library/media center houses 12,000 books and audio visual materials. The educator staff of 70 is composed of the Department of Defense Dependent Schools education specialists and classroom teachers. SAHS opened in 1959 with approximately 150 students. The first class graduated in 1960. The classrooms at that time were Quonset huts located across from the main Army Community Service building. Taegu, Pusan, and Chinhae students boarded at SAHS as there were no high schools in those areas until 1967. In the fall of 1967, Taegu opened its high school, which alleviated the long drive for students. Construction began on the new high school in 1981 and was completed in the fall of 1982. In addition to the main, arts, and gymnasium buildings a new structure which includes a JROTC section was opened in 1987.
