What Is Response to Intervention?
According to the RTI Action Network, "Response to Intervention (RTI) is a multi-tiered approach to help struggling learners. Students' progress is closely monitored at each stage of intervention to determine the need for further research-based instruction and/or intervention in general education, in special education, or both."
Resources on this page are organized around the three tiers associated with RTI:
Tier 1: Whole-Class Materials

Tier 2: Materials for Targeted Groups

Tier 3: Materials for Students with Special Needs
