RtI is a multi-tiered framework used in Thompson School District to provide academic and behavioral support to all students. It uses high quality instruction and increasingly intensive interventions matched to student needs. Students move between the three tiers - classroom, supplemental, and explicit instruction - based on their response to interventions as measured by progress monitoring. The problem-solving process and data-driven assessments are essential to the RtI model. Parent and community engagement is also important for student success.
