The problem addressed in this study is the disproportionality in office discipline referrals (ODRs) for Black students at a Northeast Florida Middle School despite the implementation of School-wide Positive Behavioral Interventions and Supports (SWPBIS). The purpose of this qualitative case study was to understand middle school teachers' perceptions of SWPBIS as a strategy to reduce ODRs for Black students at a Northeast Florida Middle School so that the disproportionality numbers decrease. Using purposive sampling, the researcher selected eight teachers from a Northeast Florida Middle School to achieve saturation. The criteria for participation required educators to possess at least three years of teaching experience and at least one year of SWPBIS implementation. A focus group comprising two teachers explored the efficacy of SWPBIS in reducing ODRs for Black students. NVivo software facilitated the coding of participant responses to the two research questions: What are the Northeast Florida Middle School teachers' perceptions regarding the implementation of SWPBIS? What are the Northeast Florida Middle School teachers' perceptions about the impact of SWPBIS on reducing disproportionality in ODRs? The study identified: varying perceptions of SWPBIS effectiveness, reducing problem behaviors for Black students, limitations of SWPBIS, concerns surrounding committee transparency, and reduction in ODRs disproportionality. Training in restorative justice and cultural competency is recommended for educators, alongside the establishment of transparent data systems to foster community and student engagement, which are vital for the effective implementation of SWPBIS. Develop a behavioral management framework to address racial imbalances. Future research should integrate responsive practices into SWPBIS.
