RTI       Response To Intervention



    The reauthorization of the Individual with Disabilities Education Act (IDEA 2004) changed the way students are evaluated for special services by encouraging schools to use research-based interventions to address diverse students’ needs early on.

    What is RTI?

    Response to Intervention (RTI) is not a particular program, curriculum, or model. Rather, it is a framework for allocating instructional services that are aligned to students’ individual needs. It aims to prevent unnecessary assignments to special education through the provision of tiers of intervention and continuous progress monitoring.

    RTI includes:

    Providing tiers of increasingly intensive, research-based intervention matched to students needs Measuring and continually monitoring students’ progress over time

    Using resulting data to drive educational decision-making

    The purpose of RTI is: 

    To focus on prevention and early identification of students in need of special services

    To better integrate services between the general and special education population

    The Multitiered Intervention Model

    RTI uses a multitiered model of service delivery to promote efficient response to students’ needs.  Each tier provides increasingly intense support structures to ensure that students succeed.

    Tier 1: Core Instructional Interventions

    General curricula for all students

    Proactive interventions based on instructional variables within whole-group instruction

    Tier 2:Targeted Group Interventions

    Supplemental instruction for students who are not successful in Tier 1

    Targeted interventions oriented towards small-group instruction

    Explicit instruction, rapid response

    Tier 3: Intensive, Individual Interventions

    Individualized instruction for students who are not successful in Tier 2

    Intensive interventions oriented towards individual students

    Diagnostic assessments to determine student need

    Higher intensity, longer duration
