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

In Kansas, across Grades 3–7 in reading and all grades in 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 Kansas Assessment Program (KAP), Curriculum Associates evaluated KAP scores and proficiency levels for 18,320 students in Grades 3–8 across 15 school districts. These analyses examined the difference in state 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.
