The school offers programs that support English Language Learners and some Special Needs students.  The school has a history of successfully differentiating for a diverse group of learners.  The educational philosophy and practice with English language learners and Special Needs learners is to immerse them in mainstream classes whenever possible and support them there in order to assure their success.

The school offers religious education courses and also integrates a Christian worldview within the entire curriculum.  The school does not seek to force students into religious choice, but to offer religious education to increase understanding between students and cultures in the school, to motivate advantage students to help the disadvantage, and to create highly virtuous students.
