Proven Impact of Consistent Zearn Usage

State and district impact studies examine the effect of consistent Zearn Math usage on state and interim assessment scores. Quasi-experimental research shows that students who consistently complete 3 or more grade-level Zearn Math lessons per week (with each lesson taking around 30 minutes) outperform matched peers who do not engage with the platform.
