• About the Two-Way Bilingual Immersion Program

    The Foussat Two-Way Bilingual Immersion (TWBI) program nurtures a vibrant learning community in which students from diverse backgrounds speak, read and write in Spanish and English and participate in multicultural studies and experiences as part of their education. Highly qualified teachers use a curriculum based on state standards. Students acquire biliteracy, exemplifying language and academic proficiency.


    Students enter the program in Kindergarten and can continue through 8th grade and then follow a pathway in high school. In high school, they will have opportunities to expand their Spanish skills or learn a third language. Students can potentially earn the distinctive State Seal of Biliteracy on their HS diploma, certifying attainment of a high level of literacy and fluency in two or more languages.
