Dual Language Immersion & Transitional Bilingual Programs

San Lorenzo Unified Language Programs

The Transitional Bilingual Program began in 1992 at Colonial Acres Elementary and expanded to Hesperian Elementary in 1999. Colonial Acres continues to provide a transitional bilingual program, while Hesperian Elementary began transitioning into a Dual Language Immersion program in 2019. The Dual Language Program currently serves grades K-5 and will be continuing into 6th grade for the 2025-2026 school year at Edendale Middle School.

How Our Programs Work

Our district provides two models:

  • The Two-Way DLI model is designed for both English-speaking and non-English-speaking students, with both groups learning in both languages. Available at both elementary and middle school levels
  • Developmental Bilingual programs build on a student’s first language, Spanish. They establish a strong foundation while incrementally building language transfer to English, supporting bilingualism as the end goal.

Starting in kindergarten, students are taught in English for 20% of the day and in Spanish for 80% of the day. The amount of English taught throughout the day gradually increases each year until 4th grade, when students are taught 50% in English and 50% in Spanish. Interactive lessons encourage students from both language groups to help each other understand, speak, read, and write each other’s home language. Through this enriched educational environment, all students gain a second language.

By the end of our program, students will achieve the following goals: 

  • Acquire high levels of oral language proficiency and academic literacy in both English and their second language
  • Gain academic achievement in the content areas in both English and their second language
  • Build positive self-esteem and cultural awareness
  • Earn the California Seal of Biliteracy

About Dual Language Immersion (DLI)

As defined by the California Department of Education, Dual Language Immersion (DLI) is a "language acquisition program that provides integrated language learning and academic instruction for native speakers of English and native speakers of another language, with the goals of high academic achievement, first and second language proficiency, and cross-cultural understanding." 

The following three pillars of DLI work together to build a strong pedagogical foundation for success both inside and outside the classroom:

  • High Academic Achievement – Students will achieve high academic standards in all subjects, regardless of the language of instruction.
  • Bilingualism and Biliteracy – Students will develop high proficiency in both languages, including reading, writing, and speaking fluently in both languages.
  • Sociocultural Competence – Students will build an understanding and appreciation of different cultures and perspectives, fostering intercultural communication and understanding.

About Transitional Bilingual

According to the California Department of Education, "Transitional Bilingual is a language acquisition program for English learners (EL) students that provides instruction to pupils that utilizes English and a pupil’s native language for literacy and academic instruction and enables an EL student to achieve English proficiency and academic mastery of subject matter content and higher-order skills, including critical thinking, in order to meet state-adopted academic content standards."

 

Transitional Bilingual classrooms provide academic instruction in a child’s native language (Spanish) with targeted amounts of English instruction that increase each year.
