This study illuminated the perspectives of school psychologists who have developed behavior intervention plans (BIPs) that support successful change in student outcomes. A total of 15 school psychologists from two different school districts were interviewed using the critical incident method; participants shared their perceptions of effectively implemented behavior intervention plans. The participants emphasized the need for consistent communication among the team members, collaboration with key stakeholders, making modifications as needed during the implementation period, and adequate time to for school psychologists to provide training to teachers. The findings of this study emphasized the importance for school teams and other school stakeholders to understand the factors that are needed when they are addressing student behavior.
