Tuition and Fees

We strive to be an intentionally diverse community, where all are not only welcomed, but also belong.

Our tuition model is an expression of our values and is intended to make the OCS experience accessible to learners of all socioeconomic backgrounds.

In determining tuition, we carefully consider the financial circumstances of each family. We recognize that no matter your income range, the cost of an OCS education is a significant financial investment. Your contribution to tuition enables us to offer an unparalleled experience with all the qualities that make OCS an exceptional place for students to grow, the best and brightest educators, inspiring teaching spaces, and meaningful learning opportunities outside the classroom.

Tuition Payment Options

In order to accommodate families, we have three different options for paying tuition for the 2026–27 school year. Each enrolled family can view and manage their payments in their FACTS account:

  • One payment due in June (Full Tuition Payment Discount–5%)

  • Two payments due on June 1st and November 1st (Bi-Annual Tuition Payment Discount –3%)

  • 10-month payment plan June – March
