Table of Contents
Most RTI frameworks organize interventions according to intensity of intervention and frequency of data collection. Typically, interventions are organized into a pyramid. This Action Tool focuses on developing a three-tiered system. [Note: Some RTI proponents advocate for more than three tiers, in which case developers would still use the principle of organizing interventions by intensity and frequency of progress monitoring.]
The purpose of organizing resources and supports into a tiered system is to assist the RTI Intervention Team in identifying interventions and instructional strategies and materials that may be effective in meeting the needs of struggling learners. The structure allows the team to see how well the student is responding before recommending a new intervention; for example, one that is more intense. Because staff members do not always know what supports and services are available, the tiered model provides a means for showcasing them. The tiered structure also enables staff members to note where there are gaps in service.
