Two-Way Immersion

Two-way immersion programs integrate native English speakers and speakers of another language, providing instruction in both languages for all students. Two-way immersion programs promote bilingualism and biliteracy, grade-level academic achievement, and positive cross-cultural attitudes and behaviors in all students.

CAL is exploring ways to expand its activities around Bilingual, Dual Language, and Two-Way Immersion Education. Watch our website for updates.
