Analysis of consistent Zearn Math users and a comparable group of low- or non-users, across 6 districts in Nebraska, shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. For this analysis, 784 students who completed an average of 3+ Zearn Math lessons per week, during the 2021-2022 school year, were matched to similar students who completed fewer than one lesson per week using the quasi-experimental method Coarsened Exact Match (CEM). Consistent users were matched to low- or non-users on pre-Nebraska Student Centered Assessment System (NSCAS) scores in English and Math, grade, and seven academic or demographic factors. In comparison to matched low- or non-users, consistent Zearn Math users gained an additional 25 scale score points on the NSCAS (effect size=0.40) and were more likely to increase their proficiency level. Results were consistent across historically marginalized subgroups. [This report was published by Zearn.]
