Measuring Elementary Student Reading Gain in the Context of School-Implemented Multitiered Systems of Support

There is limited research with mixed results about student reading gains in Grades 1 to 5 within typical school-implemented Response to Intervention (RTI). As part of a larger study, we used school-administered screening data on a widely used computer-adaptive test (Measures of Academic Progress) to describe reading gains across one academic year. We observed relatively faster growth in the first grade than in the later grades. We found stronger growth for students not identified with a disability relative to students with low or high-incidence disabilities or a 504 plan. We explored moderation of gains for students receiving tiered interventions based on administrators’ interviews about RTI implementation. We observed that better ratings of administrators’ articulation about using the evidence-aligned RTI components of progress monitoring, data-based decision-making, and Tier 2 interventions were related to greater gains for students receiving Tier 2 or 3 intervention. We discuss implications, limitations, and directions for future research.
