Research Snapshot

Landmark study of over 800 schools and 100K+ students

At a Glance


A new landmark study in terms of breadth of schools and years of usage shows new evidence of Zearn Math effectiveness.  Findings include:

  • 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 relative to schools that used other high-quality instructional materials alone.
  • 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.
