| Sumario: | Background: The Spot Vision Screener has become widely deployed for school-age vision screenings. This study analyzes the associations between Spot screening outcomes and academic performance among third-grade students. Methods: Objective school screening data using the Spot Vision Screener were collected in the state of Oregon. Spot screening results were compared to the publicly available standardized state test scores in English and Math for third-graders across all participating schools. Individual student test scores were compared to Spot screening results in a large school district to further analyze the specific vision conditions most associated with test performance. Results: In 2016-2017, a statewide trend was observed: Schools with a greater percent of thirdgraders failing vision screening (n=27,792) had more students not meeting state standards on the English (r^²=0.12) and math (r^²=0.10) exams. Individual data from a large school district were analyzed in 2017-2018 (n=2801) and 2018-2019 (n=2244) to compare third-grade standardized test performance between children who passed and failed vision screening. Children who failed the vision screening for any condition showed at least a 13% lower median percentile rank on both state tests compared to students who passed vision screening (mean difference -10.87% English and -11.29% for math). Hyperopia, astigmatism, and strabismus were associated with the lowest test scores, while myopia was associated with average test scores. Conclusions: This study demonstrates that vision conditions detected by the Spot Vision Screener, specifically hyperopia, astigmatism, and strabismus, are associated with significantly lower standardized test scores in third-grade students. The data provide insights for further modifying Spot screening vision criteria to capture the most at-risk students.
