Impact of Time and Lesson Pass Rates on Student Learning Gains

This study, conducted by Curriculum Associates, examined fall-to-spring score gains on the i‑Ready Diagnostic for groups of students with differing levels of exposure to i‑Ready and differing Lesson Quiz pass rates. Students who used i‑Ready as recommended—for an average of 30–49 minutes of i‑Ready per week who passed at least 70% of their Lesson Quizzes—made greater gains than students who did not use i‑Ready as recommended—for an average of less than 30 minutes of i‑Ready per week who passed less than 70% of their Lesson Quizzes. The difference was positive and statistically significant for all Grades K–8 in reading and mathematics. 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.
