• What is RTI?

    RTI Components


    Response to Intervention (RTI) is a comprehensive assessment and intervention process that uses learning rate over time and level of performance to inform educational decisions while core instruction, with differentiation, is occurring.  RTI provides a framework by which students are provided high-quality instruction and interventions matched to their individual instructional needs in order to ensure academic growth.Through a team-based approach, multiple sources of data are used to develop prevention-based efforts and respond to student needs using evidence-based interventions.  Efforts are evaluated through progress monitoring and summative assessments.There are four essential components of a research-based framework for RTI are: universal screening, continuing progress monitoring, multi-level prevention system, and data-based decision making. These components, together with culturally responsive and evidence-based instruction, support both a RTI process and a RTI framework focused on improving student outcomes.

      RTI Tiers 

    Tier 1 is differentiated core instruction provided to all students.

    Tier 2 is targeted intervention provided to few students in need of additional support.

    Tier 3 is intensive intervention provided to very few students in need of more individualized support.

    *Both Tier 2 and Tier 3 are provided in addition to Tier 1 core instruction.*
