    About Limestone Charter Association

    Limestone Charter Association’s recent grantmaking is built around charter school authorization and pass-through funding for South Carolina schools. The largest grants on file are substantial, with Horse Creek Academy receiving $15,782,278 in 2025 after a $13,113,671 grant in 2024, showing a continuing funding relationship rather than a one-time award. Another major recipient, Orangeburg High School for Health, received $6,360,261 in 2025, while Orangeburg Consolidated School D5 received $5,737,308 in 2024. Those awards reflect the association’s role as a conduit for school funding tied to its charter-school mission. The foundation’s grantmaking also reaches multiple charter operators across the state, including Coastal High School in Myrtle Beach, Global Academy of South Carolina in Spartanburg, East Link Academy in Greenville, Atlantic Collegiate Academy in Myrtle Beach, and Goucher Charter Academy in Gaffney. Across these grants, the organization appears to support schools through non-programmatic, pass-through funding connected to school operations and oversight within South Carolina.

    What Limestone Charter Association Funds

    Charter school authorization is central to the association’s work, and that focus is visible in the grants list. Horse Creek Academy in Aiken received $15,782,278 in 2025 for passthrough funding, aligning with the group’s charter-school mission and support role. In the Orangeburg area, funding also followed a school-systems pattern: Orangeburg High School for Health received $6,360,261 in 2025, while Orangeburg Consolidated School D5 received $5,737,308 in 2024, both labeled passthrough funding. The association also backs K-12 charter schools in other parts of the state, including Coastal High School in Myrtle Beach, Global Academy of South Carolina in Spartanburg, and East Link Academy in Greenville. The repeated passthrough designation suggests the foundation acts as an intermediary for school funding rather than a conventional competitive grantmaker.

    How Limestone Charter Association Gives

    Typical grants are large: the distribution shows a p25 of $2,810,814, a median of $2,988,387, and a p75 of $6,204,523. The recent record also shows recurring support, not just one-off awards; Horse Creek Academy appears in both 2024 and 2025, and the Orangeburg school system appears across two years as well. Limestone Charter Association operates as an intermediary with pass-through funding and fiscal-sponsorship style grantmaking rather than individual giving. All recent grants listed go to South Carolina recipients, matching its local geographic scope.
