District Snapshot

Students who consistently used Zearn grew 2.7 grade levels in 2 years of pandemic learning

A district-wide study of the impact of consistent Zearn usage on student math achievement in a large urban district in the South provides evidence that Zearn Math helps accelerate math learning for all students.

Researchers analyzed state assessment scores from spring 2019 and spring 2021 to compare achievement growth on the state assessment for students who consistently completed three or more Zearn digital lessons each week during the 2020–2021 school year to students who did not consistently use Zearn. While this research study does not have a randomized control and differences between student groups cannot be fully ruled out, demographics were similar across all available measures. Researchers found:

  • Consistent Zearn usage resulted in 2–3x growth in scores across all starting levels of proficiency.
  • Across all levels of proficiency, students who consistently used Zearn grew more than two grade levels in two years of pandemic learning.

Consistent Zearn usage resulted in 2–3 times the growth in scores across all starting levels of proficiency.

Zearn was particularly effective for students below standard; these students had three times the growth compared to students who used a high quality curriculum alone.

Across all levels of proficiency, students who consistently used Zearn grew more than two grade levels in two years of pandemic learning.

While students who used a high quality curriculum alone fell short of state benchmarks for expected two-year growth on the state assessment, students across proficiency levels who used Zearn exceeded expected two-year growth. Students who scored below standard in 2019 grew 2.7 grade levels in two years of pandemic learning—an additional 0.7 years of learning beyond the expected two-year growth.
