History
Zearn was co-founded in 2012 by CEO Shalinee Sharma[8] and Evan Rudall, former CEO of Uncommon Schools.[9] It received $4.4 million in funding from the Bill & Melinda Gates Foundation,[8] part of the foundation's $1 billion investment into math education.[10] The company launched a K–5 online curriculum in 2017, and a K–8 curriculum in 2022.[11] Much of its content handles topics like adaptive mathematics skills, conceptual understanding, and procedural fluency.[12]
In 2025, the platform received a "strong" rating from Evidence for ESSA, which found that Zearn Math had an average effect size of +0.09 on student outcomes based on 3 studies. This included a large-scale randomized controlled trial conducted by RAND Corporation, which found statistically significant gains on the NWEA MAP assessment.[4]
