In first grade, the world language being studied is offered 80% of the time, with English language skills being offered 20%. Each year, English language instruction increases untilstudents spend an equal amount of time in both languages by middle school. These percentages of time spent in immersion in the world language are based on research and outlined by the American Council on Immersion Education (ACIE). Students who begin at an early age with CoIS and continue in the program will be completely bilingual and biliterate, ready for advanced studies in either language by the time they are ready for high school or university studies nationally or abroad. And since programs such as those available through the IBO are highly acclaimed and recognized world-wide, students have the freedom to eventually study in many countries in a network of international and national schools.
