The Response to Intervention KnowledgeBase is an online resource supporting educators in understanding and implementing the response to intervention (RTI) model. The National Implementation Research Network (NIRN) has identified four stages in the implementation of evidence-based strategies such as RTI. The first stage is Exploration, and it involves consideration of the essential components of RTI models and the district or school's readiness to implement an RTI model with fidelity. During the second stage, Installation, a district or school selects an RTI model and works actively to put in place all of the supports necessary for implementing the essential components. These supports can include staff member training, policies, implementation guides, forms, assessments, instructional programs, and software. The third stage is Initial Implementation, and it involves implementing the essential components. Initial Implementation can involve just a few components or teachers, and then implementation expands over time. When the majority of teachers are implementing all components of RTI with fidelity, the district or school is in the fourth stage, called Full Implementation. This KnowledgeBase is geared primarily toward those in the Exploration and Installation stages, with some resources for those in the Initial Implementation stage.

Task 1: Determine Decision Rules for Movement Between Tiers

Guideline: Screening and progress monitoring data inform decisions related to instruction and movement between tiers within the RTI model. Establishing rules for student movement between tiers is necessary before making such decisions.




Intervention Criteria Chart

As noted at the Center on Instruction (COI) website, "this tool was collected during school site visits conducted in 2007 for the project described in COI's report Implementing Response to Intervention: Practices and Perspectives from Five Schools - Frequently Asked Questions." This particular chart was used to identify students needing intervention. It is offered in this KnowledgeBase for example purposes only.
