Response to Intervention (RTI) is a multi-tiered approach used to identify students who may need learning or behavioral support. It begins with high-quality classroom instruction and universal screening of all students. Students who struggle receive interventions of increasing intensity, and their progress is closely monitored to determine the best support. The approach uses tiered levels of instruction, with Tier 1 focusing on quality classroom teaching, Tier 2 providing small group interventions, and Tier 3 involving individualized support. The goal is to accelerate student learning through interventions based on their response to instruction.
