An analysis of 2018-19 California SBAC results shows that students learning with Zearn Math were over 50% more likely to reach proficiency. The impact of Zearn Math was even higher in schools with large populations of English Language Learners.

Students with high Zearn Math usage were more likely to reach proficiency on the 2018-19 New York State Assessment. The impact was particularly pronounced in schools with large populations of English Language Learners and students eligible for free or reduced-price lunch, which saw up to 3X growth in proficiency rates.

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.
