Response to Intervention Key Components


  • Research-based materials and instruction aligned to core academic standards is provided universally to all students and typically meets the needs of approximately 80% of students as determined by using school wide screening data (
  • Evidence-based interventions refer to those interventions that are derived from rigorous research and have demonstrated a record of success; there is reliable, trustworthy and valid evidence to suggest the program is effective (
  • Universal screenings should be implemented to ensure core instruction is meeting the needs of the majority of students. This is typically done three times a year (fall, winter, and spring).
  • Progress Monitoring is intended to determine the effectiveness of interventions at Tiers 2 and 3. Progress monitoring is typically used with students in Tier 2 and Tier 3 and should be done on a weekly to bi-weekly basis to determine the effectiveness of the interventions. Best practice is to monitor progress with instruments with established reliability and validity.
  • Data-Based Decision Making is based on information obtained from assessment including universal screening, diagnostic assessment, and ongoing progress monitoring and supports effective instructional decision-making. It should involve defining the problem, employing an assessment plan, analyzing the assessment results, and developing and revising an intervention plan based on the results.
  • Multi-tiered Intervention Model refers to a model in which the intensity of interventions and frequency of progress monitoring increases as
    students participate in tiered intervention. Movement across tiers should be fluid and change based on results of progress monitoring and decisions made by data-based decision-making teams.
  • Implementation Fidelity is implementing core instruction, tiered interventions, assessments, and data-based decision-making in accordance with the three-tiered RTI process. Additionally, implementation fidelity involves implementing the core curriculum, interventions, and assessments with adherence to their research-based design. To ensure fidelity of implementation, fidelity checks should be in place such as
    observations, walk-throughs and checklists.
