In November 2019, the Legislative Budget Board published a management and performance review of the Houston Independent School District. Among its recommendations was one that concerned professional development for teachers of English learners (ELs). Specifically, the report recommended: "[S]urveying teachers of ELs to determine where they perceive their own instructional challenges to better tailor professional development focused on instruction for ELs." In accordance with this recommendation, the district administered an online survey to all content teachers in the district, specifically targeting those who worked with ELs in the following core areas: reading, language arts, English language arts, mathematics, science, social studies, and career & technical education. The survey was designed to collect data on teachers' opinions concerning the effectiveness of professional development (PD) opportunities they may have had, their knowledge and interest in various topics related to teaching of ELs, and what they believe would be useful to offer in the future. This report represents a summary of the findings from this survey.
