Curriculum
The International School of Orange County offers a bilingual French–English curriculum for preschool through 6th grade. Maternelle (preschool, pre-kindergarten and kindergarten) adapts the French Ministry of Education program to a bicultural context, with a bilingual hour where French and English teachers co-teach and a three-center approach (Direct Instruction, Guided Instruction, Autonomous Learning).

Elémentaire (1st–6th grade) continues the dual-language approach: French remains the language of instruction in many subjects, English exposure increases from about 20% in early grades to 40% by 5th grade, and by the end of Cycle 1 (Kindergarten) students read in English, by the end of Cycle 2 (3rd grade) they read in both languages, and by the end of Cycle 3 (6th grade) they read and write in both languages. The school offers the DELF language exams at the ends of 2nd and 5th grades.
