Curriculum Associates' i-Ready Classroom Mathematics Recognized with ESSA Tier 2 Rating for Driving Measurable Student Outcomes

NORTH BILLERICA, Mass., Sept. 9, 2025 /PRNewswire/ -- Evidence for ESSA has awarded i-Ready Classroom Mathematics an ESSA Tier 2 rating. A Tier 2 rating means that a program meets ESSA's definition of a well-designed and implemented study that shows positive effects on student outcomes. This recognition follows Evidence for ESSA's review of a recent multistate efficacy study of the program conducted by the Curriculum Associates internal research team, which demonstrated its positive impact on student mathematics achievement.

"This recognition from Evidence for ESSA affirms the measurable impact i-Ready Classroom Mathematics is making in classrooms across the country," said Katie Nicholson, chief product officer at Curriculum Associates. "As a company deeply committed to research-driven, effective instruction, we are proud to see this program validated by rigorous, independent third-party review. It is a testament to the strength of our curriculum and dedication of educators using it every day to support student success."

Evidence for ESSA, based at Johns Hopkins University, provides educators with reliable, easy-to-use information on programs and practices that align with the rigorous standards of evidence as defined by the Every Student Succeeds Act (ESSA). The multistate efficacy study demonstrated its positive impact on student mathematics achievement. The study examined the impact of i-Ready Classroom Mathematics across multiple states and grades. Researchers found that students using the program achieved statistically significant gains in mathematics compared to similar students who did not use the program. Based on these results, Evidence for ESSA rated i-Ready Classroom Mathematics as meeting ESSA Tier 2 standards.
