Response to Intervention (RTI): The Three Tiers of RTI instruction

Aug 8, 2025

Overview

This lecture discusses Response to Intervention (RTI), focusing on its three-tiered model and how it differs from traditional methods of providing student support.

RTI Tiers of Services

  • Tier One: All students receive core classroom instruction based on state standards.
  • Tier Two: Targeted supplementary support is given to students needing extra help, typically 20–30% of the school population.
  • Tier Three: Intensive services are provided to a small group, sometimes including special education.

Comparison with Traditional Service Models

  • Traditional model includes classroom placement, remedial services, and special education as separate steps.
  • Traditional services require students to "qualify," often meaning students must fall behind before help is provided ("wait to fail" model).
  • Remedial services like Title One and special education are only accessible after significant academic decline.

Key Differences in RTI Approach

  • RTI uses ongoing assessments to identify student needs early.
  • Students receive interventions immediately once a need is identified, not after significant failure.
  • RTI aims to provide timely support, preventing students from falling too far behind.

Key Terms & Definitions

  • RTI (Response to Intervention) — a multi-tiered approach to early identification and support of students with learning or behavior needs.
  • Tier One — universal classroom instruction for all students.
  • Tier Two — targeted interventions for students needing additional support.
  • Tier Three — intensive interventions, sometimes including special education.
  • Wait to Fail — traditional approach requiring students to fall significantly behind before receiving help.

Action Items / Next Steps

  • Review the differences and similarities between RTI and traditional remedial models.
  • Be prepared to discuss how early assessment and intervention benefit student outcomes.
