Every year, students in grades 1 through 10 receive standardized testing in the Spring to see how they are doing individually and to see how the school is faring in preparing students for the future. The tenth-eleventh grades take the PSAT and eleventh and twelfth-grade students take the SAT tests.

OCS offers advanced placement courses to 11th and 12th graders dependent upon teacher availability and student interest. Courses that may be offered: English Language, English Literature, Calculus AB, Spanish Language and Culture, and Spanish Literature.
