$32 million in new grants; Overdeck family’s giving tops $500 million in education-focused philanthropy

In the second quarter of 2025, the Overdeck Family Foundation awarded more than $32 million through 52 grants aimed at accelerating improvements in academic and socioemotional outcomes for children across the United States.
The funding underscores their long-standing commitment to advancing data-driven, cost-effective educational solutions that scale impact while promoting equity and excellence.
The latest round of funding reflects the foundation’s dual focus: providing direct support to high-impact organizations and investing in research and field-building initiatives that unlock innovation, strengthen evidence, and enable sustainable growth.
Since its founding in 2011, the Overdeck Family Foundation has granted over $500 million to educational organizations and research initiatives, consistently targeting programs that combine rigorous evidence with scalable potential.
Among the new grantees this quarter are OpenSciEd, awarded $300,000 to develop an evaluation strategy for its widely used middle school science curriculum; Boys & Girls Clubs of America, receiving $250,000 to launch a STEM improvement cohort at 30 club sites; and AppleTree Institute, which received $200,000 to evaluate a low-cost version of its comprehensive early learning model.
Ensemble Learning was also added to the foundation’s portfolio, with a $200,000 grant to enhance professional development for educators serving multilingual learners.
Renewed and expanded commitments further strengthen the foundation’s investment in proven interventions.
Zearn received $6 million to increase usage of its math platform among elementary students, while LENA was awarded $5 million to scale its “talk pedometer” language development program to 115,000 children.
Arizona State University’s Next Education Workforce initiative received $4 million to expand strategic staffing models that improve student outcomes and teacher satisfaction.
Other major grants include $2.25 million to Collaborative Classroom to scale its early literacy program SEEDS of Learning; $1.67 million to the Robin Hood Learning + Tech Fund to drive blended literacy adoption in NYC schools; and $1.5 million each to ASSISTments and OnYourMark to expand evidence-based math and literacy tools.
Additional investments supported Tools of the Mind, the Museum of Science in Boston, Achievement Network, Modern Classrooms Project, and the Center for Outcomes-Based Contracting, among others.
In parallel, the Overdecks continue to fund rigorous research that underpins evidence-based decision-making in the education sector.
Accelerate was awarded $4 million to support randomized controlled trials of tutoring models and AI-driven learning innovations.
Evaluation partners, including Mathematica, Johns Hopkins Institute for Education Policy, the University of Michigan, and Stanford’s National Student Support Accelerator, received grants to study the efficacy of professional development, curriculum tools, and staffing models.
These efforts are guided by the Overdecks’ belief in applying the principles of innovation, experimentation, and metrics-based performance—core tenets of John Overdeck’s professional career—to social impact.
