The Core Knowledge Foundation is an independent, nonprofit, nonpartisan organization based in Charlottesville, Virginia, founded in 1986 by E. D. Hirsch, Jr., a professor emeritus at the University of Virginia and a noted author on education. It develops curricula, publishes educational books and materials, and provides professional development for educators, while supporting a growing network of Core Knowledge schools. The organization operates within the nonprofit education sector and aims to expand access to knowledge-based curricula. Its products and services are targeted at educators and schools implementing Core Knowledge frameworks, offering structured teaching resources and ongoing professional learning to improve classroom instruction. In May 2026, the foundation announced a partnership with Six Red Marbles to develop two new free K-8 arts curricula, Core Knowledge Visual Arts and Core Knowledge Music, as part of a broader effort to enrich cross-curricular learning.
