This study looks at a group of Hispanic English Learners from a region in deep South Texas that is situated along the U.S.-Mexico border, and how their sense of belonging, acculturation, and their perception of the teacher-student relationship impacts academic achievement on the STAAR End-of-Course state assessments for English I and English II. There are limited studies on this population of students and these independent variables. Results from this study would help educators and school leaders assess student needs to improve student learning and close academic achievement gaps.
