Response to Intervention or RTI is an intervention program that aims to identify students who are struggling in 1 or more areas in their grade level content. It uses targeted and research-based interventions in addition to their regular grade-level instruction, to help them close those gaps in their foundational skills. An important part of RTI is measuring progress and providing more support to students who need it.
The goal of RTI is for the school to intervene and support the learner until they reach grade-level proficiency.
