The River Falls State Teachers College joined the American Association of Teacher Colleges in 1924. The organization began nationwide accrediting in 1927, and continued in the role until superseded by the American Association of Colleges for Teacher Education in 1948. (See UWRF Series 14) The purpose of the American Association of Teachers Colleges was to make more effective the administration of teacher-training institutions and to disseminate information. Included among the materials in the series are a 1929 inspection report of the River Falls State Normal School with related courses; annual reports from the school to the Accrediting Committee, 1930-1949; bulletins and correspondence, including AATC membership lists; and miscellaneous questionnaires including a variety of interesting materials, among them student cost, library and curriculum surveys.
