Ontario Christian Schools - The Original Schoolhouse

Ontario Christian Schools – The Original Schoolhouse


In 1944, a group of men and women from 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.


To provide and promote a Biblically-based, quality education that nurtures the children of Christian parents to grow in God-centered discipleship, equipped with vision, understanding, discernment, and service in order to renew all relationships and culture to be under the authority of Jesus Christ.

About Ontario Christian

Ontario Christian is non-profit and independent, owned and directed by parents and friends of Christian education.

Academic excellence is a non-negotiable at Ontario Christian. More than 95 percent of our students go on to attend four-year colleges, including UCLA, USC, Cal Poly Pomona, Biola, Westmont, and California Baptist University (click here for more info). The school is accredited by the Western Association of Schools and Colleges (WASC) and Christian Schools International (CSI), and our courses are approved by the University of California and California State University systems.

We believe it takes the home, the church, and the school to provide the best Christian education for our children. For that reason, we encourage parents, grandparents, and extended family to be part of the Ontario Christian community.
