Although our students are non-native speakers of English, the school considers English a first language and teaches it as it is taught to native speakers as of the formative years of a student at I.S. In twelve years of formal schooling (and two years in pre-school) all courses are taught in English with the exception of Arabic language instruction and Social Studies (in the Lebanese Program) which are taught in Arabic. Therefore, I.S. graduates are fluent in oral and written English. We also prepare our students to sit for and meet TOEFL and SAT scores requirements.
