Response to Instruction and Intervention, or RTI2, is a teaching system that uses a data to identify students' specific needs and match those needs with appropriate instructional strategies.
The RTI2 Framework has three tiers. Each tier provides differing levels of support.
- In Tier l, all students receive research-based, high quality, general education instruction that incorporates ongoing universal screening and ongoing assessment to inform instruction.
- In Tier ll, intervention is implemented when assessment indicates that a student is not making adequate gains from Tier I instruction alone. In addition to Tier I instruction, students are provided small group interventions designed to meet their specific needs. These students are progress monitored weekly or every other week using a tool that is sensitive to measuring changes in the student’s individual skills.
- In Tier III, more intensive interventions are provided to students who have not made significant progress in Tier II, who are more than 1.5 grade levels behind, or who are below the 10th percentile. These students are progress monitored weekly or every other week using a tool that is sensitive to measuring changes in the student’s individual skills.
