When Fort Clark's Seminole-Negro Indian Scout Detachment was disbanded by the U.S. Army on September 30, 1914, the Seminoles were required to relocate to Brackettville. They held school in their church until new grounds were purchased by the Brackett Independent School District in March 1919 from J.F. Maddux for the purpose of providing a site for a "colored school" for Brackettville's Seminole-Negro community. The old Maddux homestead, a two-story limestone structure built in 1870, served as the building for the school, which was named George Washington Carver School. The first floor was used for classrooms while the second floor was leased to the Black Masonic Lodge until 1923. In 1930, the structure was condemned as unfit and unsafe for school purposes. The second story of the building was thus removed in 1944 and first floor was remodeled inside and stuccoed on the outside. The building was again used as classrooms for the primary and elementary grades while high school classes were conducted in a new building completed in early 1944 by the 162nd Engineer Squadron of the 2nd Cavalry Division then stationed at Fort Clark.
At the time, Carver School was the only accredited Black school between San Antonio and El Paso. The Seminole Indian Scout Cemetery Association was deeded the school grounds by the Bracket I.S.D. in November 1965. The original stone schoolhouse has since served as a meeting hall and cultural center for the Brackettville Seminole Community, including local Juneteenth celebrations and Seminole Day each September.
