The Houston Independent School District (HISD) offers two primary bilingual programs for Spanish-speaking English learners (ELs). EL students in the district's two main bilingual programs (Transitional and Dual Language) are instructed in both English and Spanish. The relative amount of instruction in each language depends on both program and grade level. Students in the Transitional Bilingual Program have the option of entering a "pre-exit phase or strand" in grades 3 through 5 as long as certain criteria are met. In this phase, English instruction is emphasized while introduction and reinforcement of new concepts are done in the primary language. This report summarizes data from ELs who are in the pre-exit phase of the district's Transitional Bilingual Program (grades 3 through 5) during the 2018-2019 school year.
