Response to Intervention



…an assessment and intervention process for systematically monitoring student progress and making decision about the need for instructional modifications or increasingly intensified services using progress monitoring data.

RTI is a general education approach that aligns resources from general remedial and special education through a multi-tiered service delivery model in order to provide scientific, research-based interventions to struggling students.


Multi-Tiered Model

  • Each tier represents increasingly intense level of services associated with increasing levels of learner needs.
  • All students, including those with disabilities, are found at Tiers I, II, and III.
  • The nature of the academic or behavioral intervention changes at each tier, becoming more rigorous as the student moves through the tiers.
  • Students move up and down the tiers depending on need.
