Response to Intervention (RTI) is the process of meeting the academic and behavioral needs of all students through a 3-tier approach. Its goal is to identify struggling students early and provide appropriate interventions. Providing early intervention increases the chances of student success.
Tier I consists of high quality instruction in the student’s regular classroom. This meets the needs of most students (approximately 80 - 90%).
Tier II combines the high quality instruction in the classroom with an evidence-based intervention targeted to meet the specific needs of the student and provided in a small-group setting. Assessments aligned to the specific intervention are administered, data is collected, and the student’s performance is monitored. Tier II support is needed by approximately 5-15% of the student population.
Tier III interventions are provided to the students who do not make progress at Tier II. Tier III interventions are more intensive, evidenced in both the frequency of the intervention sessions and the smaller-group setting (less than 4 students). Student performance data is collected more frequently and analyzed to identify successes and failures in the intervention process. Tier III represents a very small portion of the student population (1-5%).
