According to 2016-2017 school enrollment data, 31.6% of K-5 students were English Learners (ELs) in the San Francisco Unified School District (SFUSD). Of the many languages spoken at home by students, the most popular languages other than English are Spanish (19.14%) and Cantonese (15.88%). To respond to their needs, SFUSD offers programming that allows students to develop English fluency and content mastery through the use of their native language. According to their "Vision 2025" public education plan, San Francisco Unified School District (SFUSD) made a commitment to expand Dual-Language Immersion (DLI) and Biliteracy (BL) language pathway programs to better serve English Learners' (EL) needs. However, before the district fully expands the availability of language pathways, it should continually assess and evaluate the effectiveness of the existing models. This report aims to provide the Multilingual Pathways Department (MPD) a general overview of the current implementation of Spanish Biliteracy (BL) and Dual-Language Immersion (DLI) pathways at the school site level. It identifies trends that exists within and across school sites as it relates to the key components of bilingual programming. More specifically, it focuses on the ratio of ELs to total students in classrooms, the distribution of the language of instruction, and English Language Development (ELD) instructional practices. Furthermore, it provides key recommendations that will strengthen their Spanish pathways options, and consequently, improve EL success.
