Evaluation of Istation's Early Reading Assessment Efficacy

This technical report presents the findings of a mixed-methods evaluation study conducted by the Center for Research and Reform in Education at Johns Hopkins University, focusing on the efficacy of Istation's Early Reading Assessment and Curriculum in a South Carolina school district. The study compares the MAP reading growth of students using Istation's assessments with a matched control group of students who did not use the program. The report outlines the research design, methodology, and participant demographics, detailing the analytical approach and results from quantitative analyses. Key findings indicate that students using Istation significantly outperformed their peers on the MAP reading assessment over a two-year period, particularly in younger cohorts. The report also discusses the impact of adherence to recommended usage guidelines on reading gains. The evaluation aims to address specific research questions regarding achievement growth and predictive scores, contributing to the understanding of Istation's effectiveness in enhancing student reading outcomes.
