Equipping students to walk with Jesus and impact the world for Him

Expected Student Outcomes

To become equipped to walk with Jesus and impact the world for Him, students will…

  • Understand God, His world, and their place in it.
  • Think critically and Biblically.
  • Collaborate with others, respecting them as God’s image bearers.
  • Communicate truthfully and effectively.
  • Create ideas, products, and solutions.


Students achieve the expected student outcomes; use their learning to serve God and others; are prepared for college, career, and citizenship; follow Jesus; and participate in the local church.


  • The purpose of Christian education is equipping students to walk with God and impact the world for Him.
  • Parents are responsible for their children’s education. Okinawa Christian School International partners with parents by providing Christian education.
  • Students are our future. They are full of potential, are responsible for their learning, and are responsible for using it to serve God and others. We value student diversity seen in learning styles, abilities, and cultural backgrounds.
  • Staff (the living curriculum) model Biblical thinking and living, build Christ-centered community, focus on OCSI’s mission, empower others, use best practice, grow professionally, and are qualified and committed to carry out the statement of faith, vision, and philosophy.
  • Our program addresses the whole person, is communicated in English, and uses an American-style approach. It is Biblically based, recognizes all truth is God’s truth, emphasizes sharing the Gospel and discipleship, and encourages Biblical thinking and living.

Statement of Faith • We believe in:

  • The inerrancy of the Holy Scriptures as originally given; their plenary inspiration by God, and their supreme authority as the only rule of faith and practice.
  • The Trinity of the Godhead—Father, Son, and. Holy Spirit, who are the same in substance, equal in power, and glory.
  • The essential, absolute, and eternal deity of the Lord Jesus Christ, His real but sinless humanity, His substitutionary and atoning death as the all-sufficient sacrifice for sin. His resurrection from the dead on the third day in that very body that had lain in the tomb, His ascension into heaven as the only Mediator between God and man, and His visible personal return in power and glory.
  • The personality and deity of the Holy Spirit by Whom the believer is regenerated and sanctified through the Word of Truth.
  • The lost estate of man through the Fall and his salvation solely by grace through faith in Jesus Christ, whose righteousness imputed to him is the only ground of his acceptance before God.
  • The resurrection of the body, the judgment of the world by our Lord Jesus Christ, the everlasting and conscious punishment of the lost.
  • The spiritual unity of all who truly believe in the Lord Jesus Christ and their duty to maintain in all their relationships a standard of life and doctrine that is in conformity with the teaching of God’s Word.
