A district-wide study in Arizona reveals that students with high Zearn Math usage were twice as likely to improve scores on the AzMERIT Test, Arizona’s state-wide achievement assessment.

An analysis of outcome data of nearly 10,000 students, spanning 131 schools across five states, found that grades with high Zearn Math usage outperformed state averages across all achievement levels on the Smarter Balanced Assessments, with the highest gains in 5th grade.

A survey of 345,000 students found students who completed more Zearn Math lessons were more likely to report a love of math. Across all grades, as high-struggling students spent more time learning with Zearn Math, they increasingly reported that they believe they can get better at math.
