Mission Statement
Within an environment conducive to learning, San Antonio Christian School strives to provide a Christ-centered, multi-faceted education to lead children into a personal relationship with Christ, as well as to guide and motivate students to be successful in all their endeavors.
The purpose of Adventist education at San Antonio Christian School is to make our education Christ-centered and to nurture students in the development of the whole person: spiritually, physically, mentally, socially, and emotionally. We desire to provide quality academics in a safe and positive environment, develop a personal sense of mission and service in the community, and ultimately produce citizens who will successfully impact their families and society. Students flourish in an atmosphere of love, acceptance, and encouragement. The entities listed below are partnering with and supporting us in this endeavor.
