Texas Randomized Controlled Trial (2022–2024) | RAND
A large-scale randomized controlled trial, conducted across 10,000 students in grades 3–5 in 64 schools in a large urban Texas district, found causal evidence of positive, statistically significant impacts of Zearn on student math achievement, as measured by the nationally normed NWEA MAP Growth assessment.
- Zearn had a positive and statistically significant impact of +0.11 standard deviations (SD) on students’ NWEA MAP scores. That impact was slightly larger — +0.13 SDs — for students who began below proficiency. These impacts are equivalent to a four-percentile increase in math achievement over two years. These statistically significant MAP findings were designated as exploratory outcomes.
- On the Texas STAAR exam — the study’s confirmatory measure designed to assess on-grade proficiency — students in Zearn schools scored +0.07 standard deviations higher than peers not using Zearn, rising to +0.10 SD for students who began below proficiency. While positive, these gains did not reach statistical significance.
- Effects for English learners, while positive, were smaller than for other subgroups. In response, Zearn is launching a multi-year rollout of Spanish-translated digital lessons beginning in the 2025–26 school year.

Louisiana Quasi-Experimental Design Study (2023–2024) | JOHNS HOPKINS UNIVERSITY
A Johns Hopkins University quasi-experimental study (2023–2024) of over 7,000 students in three suburban and rural Louisiana districts found districts using Zearn with dedicated implementation support (e.g, school coaching, educator training, usage monitoring) significantly outperformed peers on the state math assessment.
- Zearn had a positive and statistically significant impact of +0.20 standard deviations (SD) on students' math LEAP scores, Louisiana's state assessment.
- Gains were consistent across student subgroups, including English learners, economically disadvantaged students, and students with disabilities.
- Study authors note that this effect size represents a large practical impact of Zearn on LEAP scores, based on widely accepted benchmarks for interpreting educational interventions (Kraft, 2020).
