About the company
Castlewood School District 28-1 (doing business as Castlewood Elementary School – 02), a U.S. local government entity and public school district located in Castlewood, South Dakota, operates as a federal grant recipient in K–12 education programs, receiving funding from the Department of Education's Office of Elementary and Secondary Education and the Department of Agriculture's Food and Nutrition Service. The district does not hold federal contracts or IDVs; its federal footprint consists entirely of direct and pass-through grant awards to support rural school operations.
As a grant recipient, Castlewood School District holds direct prime awards under the Small, Rural School Achievement Program formula grant, which runs on a consistent annual schedule through the Office of Elementary and Secondary Education. The district received prime awards on July 1 in each of 2022, 2023, 2024, 2025, and 2026, with ultimate completion dates typically falling in late September of the following year. Recent sub-recipient awards flow through the South Dakota Department of Education and include allocations under Title I Basic, Title IIA REAP (Rural Education Achievement Program), Title IV, and National School Lunch Program (NSLP) block grant claims. The district also receives direct sub-awards under Title I Basic A Grant Allocation and NSLP block grant funding.
Castlewood's federal customer base remains concentrated and narrow. The Department of Education's Office of Elementary and Secondary Education accounts for 26 of 32 awards (97% coverage by count), while the Department of Agriculture's Food and Nutrition Service carries the remaining six awards—all related to school meal program administration and reimbursement. Combined obligations across all federal awards total $1.1 million as of the source snapshot. Activity has fluctuated modestly over the past five years, ranging from one award in 2022 to six in 2025, with two awards recorded in 2026. One award faces ultimate completion within the next twenty-four months, indicating minimal recompete exposure in that window. The district functions as a sub-recipient in the majority of its non-prime work, receiving pass-through funding from South Dakota Department of Education intermediaries rather than direct federal awards. Prime grant work (61% of awards) centers on rural education achievement programming; sub-recipient work (39%) focuses on Title I, Title IIA, Title IV, and school lunch program implementation and reporting.
