Response to Intervention (RtI) is one example of the different multi-tiered systems of support (MTSS) that are described as early intervening services (EIS) under the Individuals with Disabilities Education Improvement Act (IDEA, 2004). When a similar multi-tiered approach is applied to behavioral interventions, it is usually referred to as positive behavioral supports (PBS) or positive behavioral intervention supports (PBIS). RtI is a multi-tiered approach to service delivery that encompasses general and special education. It is a result of the growing evidence on how to identify and address the needs of students with and at risk for learning disorders. AOTA has developed a collection of RtI resources (e.g., consumer brochure, practice advisory, FAQ) to advocate for and articulate the OT role within this approach.
