The Christian-based curriculum is comparable to most private, college- preparatory schools with the objective to develop in each student a maximum proficiency in language arts, an active proficiency in the Spanish language, and a sound understanding in the areas of math, science, and social studies. In addition to the strong academic program, the school offers an elective program in the following: art, typing, computer, guitar, SAT math/verbal, Writers Workshop, newspaper, yearbook etc. Physical Education and Bible are required.

International Christian School is a private, coeducational school, which offers an educational program from pre-kinder through twelfth grade for students of all nationalities. The school was founded in September 1977 because of a need for an English- speaking Christian school in San José. The school follows a stateside schedule: classes are in session from mid-August until mid-December and from mid - January until the end of May.
