Response to Instruction and Intervention (RtII) is a multi-step framework of providing educational support and instruction to all students in the area of reading. Individual student’s progress is monitored and results are used to make decisions about further instruction and intervention.
The RtII process typically has three tiers. Each tier provides differing levels of support.
- In Tier I, all students receive high quality curriculum and instruction in the regular education classroom. The teacher assists all learners.
- In Tier II, the school provides interventions to students who need more support than they are receiving from the general curriculum.
- In Tier III, students are given more intensive instruction and intervention.
