i-Ready Instruction accelerates student growth
New research based on data from over four million students who took the i-Ready Diagnostic during the 2016–2017 school year finds that students who used i-Ready Instruction experienced greater learning gains than those who did not use the program. This research meets the criteria for ESSA Level 3.
Strong Learning Gains for Students using i-Ready Instruction
Students who used i-Ready Instruction experienced substantial learning gains compared to students who did not. Students receiving recommended levels of i-Ready Instruction experienced 39% greater gains for English language arts (ELA) and 38% greater gains for mathematics. These results were supported by strong effect sizes and statistically significant gains.

The study showed significant score gains across key student groups. Effect sizes were large for non-Caucasian students, students with disabilities, economically disadvantaged students, and English learners. Based on these results, educators can conclude with confidence that i-Ready Instruction is an effective intervention solution for all students.
