Bible is taught at every grade level at Ontario Christian School

Biblically-Based Curriculum

Students learn to discover and appreciate God-inspired wisdom and beauty in all subject areas. With a firm Biblical foundation, students build vibrant and intimate relationships with the Triune God. Our goal is to prepare students to be distinctive types of leaders wherever God calls them.

Each subject is taught with the assumption that God is in control of every square inch of creation. So, whether it’s English, History, Science, Physical Education, or Math – students are learning about the subject matter and their God.
