Approximately 1-5% of students will continue to experience difficulty after participation in ongoing Tier I support and inclusion in a Tier II intervention. In many cases these students have school histories of significant academic and behavioral difficulties over an extended period of time. Because their needs may be more intense and chronic, Tier III support systems are individualized. Just as with the Tier III level, schools must build on the established schoolwide system to accurately identify these students, and data-based decision making is essential.
Students with chronic and/or intense problem behaviors require specially designed and individualized interventions that match the function of the problem behavior. A simple functional behavioral assessment (FBA) is conducted to create a summary statement that forms the basis for a student’s behavior intervention plan (BIP). Expertise in the science of behavioral assessment is necessary for the development and implementation of individualized support plans.
