An approach consisting of schoolwide strategies and/or procedures designed to provide intensive individualized interventions to individual students with challenging behaviors. Once identified, students are organized into one of three categories in order to receive support. The first category includes support for all students and emphasizes expectations of appropriate student behavior and social skills. The second category provides extra support for students who aren’t successful in just the first category. Within this category students are focused on working on their social skills and self-management on top of their academic skills. The third and final category provides more intensive and individual support for students who have not been successful in just the first two categories (though, they still have access to these supports). The number of students serviced in this category is much smaller and is limited to those behaviors that are deemed highly disruptive. Students that have been identified within this category include those on the autism spectrum, and those with emotional and behavior disorders. This was previously known as Positive Behavior Support (PBS).
