Essential Features of Intensive, Individualized (Tier 3) Interventions

Tiered systems may hold particular benefit for students with intensive intervention needs, as this continuum of supports is ideally comprised of evidence-based practices. In this chapter, we explore three intensive interventions: functional assessment-based interventions (FABI), First Step to Success, and Read 180 as they feature a range of practices and programs to meet students' academic, behavioral, and social needs. We define and describe each intervention, including information on essential features necessary for drawing valid inferences: treatment integrity, social validity, as well as student performance. We also provide examples of supporting evidence, featuring treatment-outcome studies documenting intervention effectiveness. We close with clarifications and considerations for meeting the multiple needs of students requiring intensive intervention efforts.
