About Dual Language Immersion
About
The Dual Language Immersion program differs greatly from earlier bilingual programs offered in many California districts. Unlike those programs, Dual Language Immersion provides both native English speakers and Spanish speaking Academic English Learners the opportunity to learn to read, write, and communicate effectively in English and in Spanish while achieving high levels of academic achievement. This is an “additive bilingual” program, meaning that a child’s first language continues to be strengthened and augmented while he/she is gaining a second language.
In addition, students have the opportunity to develop an understanding of and an appreciation for other cultures, develop a high self-esteem and experience positive interactions with people from other cultures and countries. Participation in this program begins in TK/K and students remain in the program through fifth grade and into secondary in order to reach and maintain high levels of proficiency in two languages.
Both Spanish dominant and English dominant speakers are placed in the same classroom. Ideally, 50% of the students should be dominant speakers of Spanish, and the other 50%, dominant speakers of English. Bilingual students may also be included in the program. However, in any classroom configuration, dominant Spanish speakers should make up not less than 35% of the class, as they serve as strong models for the target language.
