RtI is the practice of meeting the academic and behavioral needs of all students through a problem-solving process with three key elements:

1. High quality instruction and research based tiered interventions aligned with individual student needs.
2. Frequent monitoring of student progress to enable results-based academic and/or behavioral decision.
3. Use of student response data in making important education decisions (such as those regarding placement,intervention, curriculum, and instructional goals and methodologies).
