Key findings:

To analyze the impact of Zearn Math on Texas student achievement, researchers used a quasi-experimental research method to measure 2023 STAAR math performance growth differences between students who used Zearn Math consistently and a matched comparison group that did not use Zearn. Drawing from a sample of 4,400 Texas students, matched students had similar 2022 STAAR math and reading language arts scores and have similar student characteristics across academic and demographic factors.

Researchers found that consistent Zearn usage increases STAAR math scale scores by 53 points on average, with gains across subgroups. Further, Zearn usage increased STAAR performance level; 62% of the lowest scoring students moved up at least one level when using the platform consistently.
