Learning gains equivalent to 1.5 months of additional instruction: schools whose students consistently used Zearn Math digital lessons saw outsized gains in state math test scores.

Positive effects compound over time: students who used Zearn Math for multiple years demonstrated even greater increases in achievement.

Evidence of impact across hundreds of schools: the study was conducted across more than 800 Louisiana schools and over 100,000 students over 5 years, showing the transformative impact of Zearn across implementations.

Sustainable impact, at scale

Put simply, the impressive effects observed in this study are an exciting indication of the scalable impact of Zearn Math across different school contexts, especially as we collectively look to accelerate learning.
