School-Wide Positive Behavior Support (SWPBS) can help schools by reducing problem behaviors, suspensions, and increasing time spent on teaching with a common language for behavior issues. However, implementing SWPBS faces resistance to change due to fears of the unknown, mistrust, peer pressure, and personality conflicts. To manage this resistance, it is important to identify all stakeholders, maintain focus and context for the change, use opposition as an opportunity, respect stakeholders, avoid ignoring resistance, define clear goals, measure progress, understand the school culture, and manage significant barriers through an evaluation plan with data collection and workshops.
