Tier Interventions

  • What is an intervention?
    • An intervention is targeted instruction to meet student skill deficit.
    • A strategy designed to help a student improve performance relative to a specific goal.

    Academic Intervention Critical Components Checklist developed by Jim Wright at www.interventioncentral.org. The checklist summarizes essential components in academic interventions.

    What's the difference between interventions at different tiers?
    Many interventions can be delivered in multiple tiers - what determines the tier is the size of the student group and the frequency of progress monitoring.
    • Tier 1 Interventions: Tier 1 Interventions are delivered as classwide interventions when a deficit is identified in more than 20-25% of the class.
    • Tier 2 Interventions: Tier 2 interventions are small group interventions (typically 3-5 students) that target an identified deficit.  Progress monitoring is done at least bi-weekly to determine effectiveness.
    • Tier 3 Interventions: Tier 3 interventions are individualized intensive interventions targeting an identified deficit.  Interventions are typically delivered in a one on one setting and progress monitoring is done weekly. 
    Helpful Links for Response to Intervention
    • What Works Clearinghouse - The What Works Clearinghouse (WWC) reviews the existing research on different programs, products, practices, and policies in education. The goal is to provide educators with the information they need to make evidence-based decisions. 
    • Intervention Central - Intervention Central provides teachers, schools and districts with free resources to help struggling learners and implement Response to Intervention.
    • National Center on Intensive Intervention - NCII builds the capacity of state and local education agencies, universities, practitioners, and other stakeholders to support implementation of intensive intervention in literacy, mathematics, and behavior for students with severe and persistent learning and/or behavioral needs, often in the context of their multi-tiered system of support (MTSS) or special education services. 
    • Evidence-Based Intervention Network- University of Missouri - To support the use of evidence based interventions (EBI) in schools, the Evidence Based Intervention Network (EBIN) was developed to provide guidance in the selection and implementation of EBI in the classroom setting. The EBIN has an extensive resource base including evidence based intervention briefs, video modeling of EBIs, information on selecting and using EBI
