Student voice is essential for PBIS, but a tool for gathering students' perspectives of PBIS is not available in the literature. The purpose of this study was to develop and validate a universal-level PBIS survey for students, the Student Perceptions of Behavior and Discipline (StPBD). This survey was designed to mobilize student engagement and guide implementation with cultural and contextual fit. Survey development was informed by literature review, feedback from users and researchers, pilot tests, and exploratory and confirmatory factor analysis. Analyses of items designed to measure aspects of school climate, student-staff relationships, and family connections confirmed these three distinct factors. Linear mixed-effect analyses revealed significant relationships between the survey, student perceptions of PBIS practices in the school, school level, discipline, and gender identity.
