Welcome to the 2025-2026 school year!
I am grateful for the start of the 2025-2026 school year and the excitement, hope, and maybe even a bit of nerves that a new school year brings. OCSI is excited and ready to partner with your family to equip our students to walk with Jesus and impact the world for Him. Our hope and prayer is that your child’s time at OCSI this school year provides rich opportunities to live out this mission each and every day.
Mr. Dan Pallmann
High School Principal
High School (Grades 9-12)
Our graduates are world influencers
Our classes are taught in English, and we use an American-style program that addresses the whole person, is Biblically based, recognizes that all truth is God’s truth, emphasizes sharing the Gospel and discipleship, and encourages Biblical thinking and living.
The OCSI high school program is designed for students in grades 9 through 12. The program provides a college preparatory curriculum that is both collaborative and challenging, culminating in a variety of AP course offerings and honors courses (English, Math). Core classes include English, Social Studies, Science, Math, and Bible. Elective courses include Physical Education, Japanese, Digital Tools, Music, Art, and Woodshop. In addition, each student receives a Chromebook as part of our 1:1 laptop program.
