Alternative education (AE) settings support students with significant social–emotional and behavioral needs. Such settings often implement individualized programming; however, this presents challenges with staffing resources and training. Application of systems to address behavior on a schoolwide level could simplify training, increase staffing flexibility, and decrease use of crisis response procedures. This 2-year, descriptive case study provides an implementation example of universal behavioral supports based on a Positive Behavioral Interventions and Supports (PBIS) framework within an AE setting. Over the course of the study, a reduction in staff use of restraint and seclusion procedures was observed. Additionally, staff perceived the framework favorably. Implementation steps are described, along with differentiation of the framework to meet the needs of a heterogeneous student population within the context of the COVID-19 pandemic.
