Carrollton High School was the oldest school in the Carrollton-Farmers Branch ISD. Land for the school was donated by DeWitt Clinton Perry and his sister Harriet Perry Warner. Construction began in December 1935, and the school opened on September 14, 1936. Although "DeWitt Perry High School" was carved in stone over the entrance, it was known as Carrollton High School, and diplomas were issued under that name. The DeWitt Perry name was officially recognized in 1962, when Turner High School opened and the building became a junior high school. The site had also been home to the first Carrollton High School building, "Old Red," which opened on January 19, 1916. That two-story building with a basement was built of red brick from the Carrollton Brick Company. Before that, students attended an unpainted clapboard school at the corner of what is now Belt Line and Erie. "Old Red" was razed in 1966 for additions to DeWitt Perry Junior High and the Harriet Perry Warner Gymnasium. The original cornerstone for "Old Red" remains adjacent to the site.
