Our History

In 1944, a group of men and women from the Ontario Christian Reformed Church took a step of faith and established a Christian school. More than 70 years later, Ontario Christian has grown from a one-room schoolhouse to the longest-standing Christian school in the Inland Valley with a community of 1,200 students. We unite students from over 200 different churches around one goal: to see Christ glorified and exalted in everyday life.

Ontario Christian is non-profit and independent, owned and directed by parents and friends of Christian education. We believe it takes the home, the church, and the school to provide the best Christian education for our children. Ontario Christian recognizes that parents are most accountable before God for the nurture of their children in the ways of the Lord. Therefore the school sees itself as an extension of the home. We believe that home, church, and school as partners in helping students to grow spiritually academically, and socially.

Ontario Christian School began as a one-room schoolhouse based in a converted garage.
