Research suggests that school climate can have a great impact on student, teacher, and school outcomes. However, it is often assessed as a summary measure, without taking into account multiple perspectives (student, teacher, parent) or examining subdimensions within the broader construct. In this study, we assessed school climate from the perspective of students, staff, and parents within a large, urban school district using multilevel modeling techniques to examine within- and between-school variance. After adjusting for school-level demographic characteristics, students reported worse perceptions of "safety" and "connectedness" compared to both parent and staff ratings (all p < 0.05). Parents gave the lowest ratings of "parental involvement," and staff gave the lowest ratings of "academic emphasis" (ps < 0.05). Findings demonstrate the importance of considering the type of informant when evaluating climate ratings within a school. Understanding how perceptions differ between informants can inform interventions to improve perceptions and prevent adverse outcomes.
