During the 2016-2017 school year, the Vision Partnership program provided vision services to approximately 3,353 students enrolled in the Houston Independent School District. This evaluation brief describes HISD students' participation in campus-based screenings and the Vision Partnership, and the academic achievement of students served by the program in the 2015-2016 school year. Students' academic achievement was measured on the 2016 and 2017 spring 3-8 STAAR [State of Texas Assessments of Academic Readiness] reading and mathematics assessments. Results indicate that a higher proportion of students enrolled in grade levels not required by the Texas Department of State Health Services to be screened failed their campus-based vision screen when compared to the results of peers enrolled in mandatory grade levels. Academic achievement data indicated that higher percentages of fourth- and seventh- grade students met the Approaches Grade Level Standard on the 2017 STAAR reading and mathematics assessments when compared to their performance on the 2016 STAAR assessments.
