What is MTSS/RtI?
Response to Intervention (RtI) is defined as “the change in behavior or performance as a function of an intervention (Gresham, 1991). RtI is implemented as a leveled or tiered approach to instructional delivery that includes interventions of increasingly higher intensity, based on a student’s need; that is, a Multi-Tiered System of Supports (MTSS). Assessment data provides the evidence of student learning, and based on this information, decisions are made about the most appropriate instruction, including interventions, that will help a student learn. Likewise, behavior management is addressed in a leveled or tiered approach, and decisions are made about the best behavioral interventions to employ based on assessment and data. A problem-solving method of decision-making is employed and results of efforts are documented. The process is intended to result in better learning opportunities (academic and behavioral) and higher achievement for all students.
