i-Ready Classroom Mathematics and California Assessment Performance

To understand the relationship between the use of i-Ready Classroom Mathematics (iRCL) core curriculum and performance on the Smarter Balanced Assessment (SBA) in mathematics, Curriculum Associates evaluated 2021–2022 SBA Mathematics scores and proficiency levels for students with access to iRCL compared to students without access to iRCL. The study is based on more than 9,000 California students in Grades 3–5. 

The research findings demonstrate positive differences between SBA scores and rates of proficiency for students attending schools with iRCL compared to similar students attending schools that do not leverage iRCL.
