The purpose of this study was to determine the effectiveness of a large, suburban school district’s RTI interventions services in raising student achievement on i-Ready Reading exams over a three-year period. This study determined the effectiveness of RTI services on the i-Ready reading scores of a selection of 135 students at a large, suburban high school. In order to qualify for the study, the students must have received RTI services and sat for the i-Ready exam in each of the three years included in the study. The study analyzed the participants’ i-Ready scores over a three-year period from the 2017-2018 school year to the 2019-2020 school year. The results provide researchers, school administrators, and other school personnel insight into what RTI model would best support student-reading achievement.
