MTSS vs RTI and PBIS- what’s the difference?
RTI, or Response to Intervention, is a tiered system of academic instruction and support PBIS, or Positive Behavior Interventions and Supports, is a system that promotes positive behavior in schools MTSS is a tiered system of academic, behavioral, and social emotional instruction and support MTSS and RTI are two different educational models that look very similar. People sometimes use the terms interchangeably.
However, RTI only looks at academic needs, while MTSS interventions cover academic, social emotional, and behavioral needs. Before MTSS, many states used RTI alongside PBIS to address academic and behavioral issues separately.
The MTSS umbrella combines elements of RTI and PBIS to address the whole student.
