The Center for Research and Reform in Education (CRRE) at Johns Hopkins University (JHU) conducted a research study to examine the impact of i-Ready Personalized Instruction (i.e., i‑Ready) on the reading achievement of students from five school districts across Massachusetts as measured by their performance on the end-of-year state summative assessment, the Massachusetts Comprehensive Assessment System (MCAS). CRRE researchers found that students who used i‑Ready with fidelity outperformed students who did not use i‑Ready on the MCAS for English Language Arts.
