What can eight years of student voice tell us about academic success? Glendale Unified School District analyzed longitudinal Social-Emotional Learning (SEL) survey data from more than 15,000 students alongside CAASPP, CAST, and ELPAC outcomes to investigate how growth mindset, self-efficacy, and social awareness relate to achievement. This session shares the district's research approach, key findings, and practical implications for educators seeking to translate evidence into action.
