This study examined students’ fall-to-spring score gains on the i‑Ready Diagnostic based on how often they used i‑Ready Personalized Instruction (“i-Ready”) and their Lesson Quiz pass rates. This study provides evidence that students in Grades K–8 who use i‑Ready as recommended make greater improvements in reading and mathematics than students who do not use i‑Ready as recommended.
