The Association of Colleges and Secondary Schools of the Southern States was organized in 1895. Each year a formal report is required of all secondary schools seeking accreditment. At the Charleston, South Carolina, meeting, December, 1925, the association authorized the commission on secondary schools to prepare a detailed statistical report of the secondary schools from the data gathered in its next annual blank, similar to the ones issued each five years by the North Central Association, known generally as the Quinquennial Report. As a result of this authorization the annual blank sent out in the fall of 1926 to all secondary schools of the Southern Association was very materially enlarged. This report is compiled from the data taken from that blank. Since every secondary school has to file an annual blank to obtain accreditation, the report embraces data on all of the 844 schools accredited by the association for the year 1926-27.
