Multi-Tiered Systems of Support (MTSS) - Response to Instruction and Intervention (RtII)

Multi-Tiered Systems of Support (MTSS) - Response to Instruction and Intervention (RtII)


Multi-tiered Systems of Support (MTSS) is a prevention framework that organizes building-level resources to address each individual student's academic and/or behavioral needs within intervention tiers that vary in intensity. MTSS allows for the early identification for students who are at risk for poor learning outcomes. The increasingly intense tiers (e.g. Tier 1, Tier 2, and Tier 3), sometimes referred to as levels of prevention represent a continuum of supports. Response to Intervention (RtI) and Positive Behavioral Interventions and Supports (PBIS) are examples  of MTSS.

Response to Instruction and Intervention (RtII) is an early intervening support process where the goal is to improve student achievement using research based interventions matched to the instructional need and level of the student. The core of RtII is the premise that ALL children can learn. In Pennsylvania, RtII carries dual meaning: first, it is a comprehensive, multi-­‐tiered, standards aligned strategy to enable early identification and intervention for students at academic or behavioral risk. Second, RtII is an alternative to the aptitude achievement discrepancy model for the identification of students. This strategy allows education professionals to identify and address academic and behavioral difficulties prior to student failure. Monitoring student response to a series of increasingly intense interventions assists in guiding instruction to prevent academic failure and provides data that may guide eligibility decisions for learning disabilities. In brief, RtII is: 

  • A data-­‐driven model to enable early identification and strategic interventions for students at academic or behavioral risk
  • A multi-­‐level instructional framework aimed at improving instruction for ALL students 
  • A shared, collaborative, decision-­‐making process among professional educators
