The school was sold and reorganized in 1915, becoming the National Training School; it was supported by Margaret Olivia Slocum Sage, a philanthropist of New York who was particularly concerned about education. (She founded the Russell Sage Foundation and made generous bequests to several schools.) The National Training School supported Black teacher development in the Jim Crow era, a time when Black education was underfunded by southern states at both the lower and upper levels.
