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

Jul 29, 2025

Overview

This lecture explains the three-tier model of Response to Intervention (RTI) and contrasts it with traditional methods of providing academic support in schools.

RTI Tiers of Service

  • Tier One: All students receive general classroom instruction targeting state standards.
  • Tier Two: Targeted supplementary support is given to students needing extra help, often 20–30% of a school.
  • Tier Three: Intensive, individualized interventions, sometimes associated with special education.

RTI vs. Traditional Support Systems

  • Traditional model includes classroom instruction, remedial programs (like Title One), and special education.
  • Students traditionally must "qualify" by showing significant failure before receiving extra help.
  • Traditional approach often described as "wait to fail," requiring students to fall far behind before intervention.

Key Differences with RTI

  • RTI provides immediate support based on early identification of student needs.
  • Ongoing assessments are used proactively to find and assist struggling students.
  • RTI aims to deliver help before students experience significant failure, reversing the traditional order.

Key Terms & Definitions

  • RTI (Response to Intervention) — A multi-tiered system for providing early, systematic academic support to all students.
  • Tier One — General education classroom instruction for all students.
  • Tier Two — Targeted, supplemental support for students at risk.
  • Tier Three — Intensive, individualized interventions for students with significant needs.
  • Wait to Fail — Traditional approach where students receive help only after demonstrating substantial academic difficulties.

Action Items / Next Steps

  • Review the differences between RTI tiers and traditional support models.
  • Understand the proactive use of assessments within RTI.
