Our high school program is an extension of the grade school program and housed on the same campus. However, our secondary students are on a separate time schedule, use a different portion of the building, and have a separate teaching faculty. We teach the Ontario curriculum content and offer Ontario credit courses while maintaining a Christian perspective. Our primary goal as a Christian school is to shape a Biblical worldview in our students that is founded on unwavering principles of truth.

We are presently permitted to grant Ontario credits toward the Ontario Secondary School Diploma, which is a privilege received by successfully meeting periodic inspections by the Ontario Ministry of Education. Secondary students at JCS are also provided with a variety of academic opportunities, including inter-school competitions, specialized field excursions, and a well-established co-operative program with many businesses and organizations in the larger community. In addition, our secondary students have access to personal laptops in class for various purposes such as note-taking, online research, and presentations.
