National research study results from two years of math learning data offer evidence that learning acceleration works at scale

Catching Up and Moving Forward: Accelerating Math Learning for Every Student

A new, national study powered by two years of math learning data for 600,000 students offers promising evidence that learning acceleration works at scale. When a struggling student experienced learning acceleration, they completed twice as many grade-level lessons and struggled less than when they were remediated.

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. Learn more about the methodology of each treatment-on-the-treated study.
