The Houston Independent School District offers two different English as a Second Language (ESL) programs for language minority students. One of these is a Content-Based ESL (CBESL) program where ESL methodology is used to deliver English instruction across a variety of subject areas. The second is a Pullout ESL program (PO-ESL) where students attend special intensive language classes for part of the day, separate from their regular all-English classes. Content-Based ESL is mainly used in the elementary grades, while Pullout-ESL is primarily a secondary-level program. This report summarizes the performance of students who were in these two ESL programs during the 2019-2020 school year. Included in the report are findings from district interim assessments of academic achievement, specifically the district-level assessments (DLAs) and the Renaissance 360 (R360).
