State Impact Research for California

How is using i-Ready Personalized Instruction with fidelity associated with state test performance?

In California, across all grades in both reading and mathematics, students who used i-Ready Personalized Instruction with fidelity demonstrated higher state test scores and were more likely to be proficient than students who did not use i-Ready Personalized Instruction with fidelity.

To understand the association between the use of i-Ready Personalized Instruction and performance on the California Assessment of Student Performance and Progress (CAASPP), Curriculum Associates evaluated CAASPP scores and proficiency levels for 150,089 students in Grades 3–8 across 49 school districts. These analyses examined the difference in CAASPP scores and proficiency rates between students who used i-Ready Personalized Instruction with fidelity and students using the program less consistently, accounting for fall performance.

This study was designed to meet the criteria for ESSA Tier 3 evidence.
