Dual Language Program (TWBI)


About the Program
In its strategic goals, Oceanside Unified School District (OUSD) promotes the preparation of students for full participation and success in a global society that is multilingual and multicultural.

The OUSD multi-site Two-Way Bilingual Immersion program nurtures a vibrant K-12 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.

90/10 Immersion Model in K-5 The first number refers to the percentage of time spent in the target language (Spanish) and the second number to the percentage of time in English. In the 90/10 model, the amount of English-language instruction increases as the students progress through the grades.

Two-Way Immersion

The program includes fairly equal numbers of English speakers and English language learners (native speakers of Spanish). Two-way immersion is a unique kind of language education because it involves two languages used for instruction and two groups of students. The programs are integrated.

TWBI Master Plan

OUSD's Two-Way Bilingual Immersion Master Plan guides the development of the program and a K-12 pathway that affords students the opportunity to develop literacy in two languages.
