Evidence for i‑Ready’s Efficacy

i-Ready’s Impact on Students’ Reading and Mathematics Achievement

i-Ready is backed by practical, rigorous research. i-Ready Personalized Instruction—the system of personalized lessons designed to fill students’ knowledge gaps and help every student reach grade-level proficiency—has been studied by numerous third-party and independent organizations as well as Curriculum Associates’ own Research team, in partnership with educators throughout the country.

Key Findings

Research has demonstrated the effectiveness of i-Ready Personalized Instruction across multiple dimensions:

Research Meeting the Every Student Succeeds Act (ESSA) Level 2 (Moderate) Evidence Requirements

• Many rigorous research studies meeting ESSA Level 2 (Moderate) evidence standards demonstrated positive and statistically significant gains for students receiving i-Ready Personalized Instruction above that of their control group counterparts in both reading and mathematics on internal and external outcome measures.

Studies Demonstrating Improvement on State Assessments

• Several independent studies (i.e., those conducted without guidance or funding by Curriculum Associates) found that i-Ready Personalized Instruction students outperformed their peers, making positive and statistically significant gains on state test measures such as the Florida Standards Assessments, Smarter Balanced Assessments, and Utah’s Student Assessment of Growth and Excellence.

Evidence of Efficacy with Special Populations

• Multiple small- and large-scale studies, including those conducted by independent and third-party researchers, have shown i-Ready has a positive impact in both reading and mathematics on students who are striving learners, English Learners, students with disabilities, and students with socioeconomic disadvantages as well as disaggregated results for students who are Black and Latino
