Records of the Voorhees School's Board of Trustees include its by-laws (1926), meeting minutes (1939, 1941, 1949-1952), and the school president's annual reports (1947-1955). Financial documentation includes records relating to building construction (1947-1948). The ACI director's correspondence (1923-1954) addresses a wide variety of issues. Background information about the school can be found in historical summaries (c.1925, 1940). This series includes a survey report of the school by the George Peabody College for Teachers (1941).

The DFMS archive on the American Church Institute (ACI) is largely focused on the years 1906 through 1967, although documentation on individual schools dates from 1867 (see AO-00-R0061-02-12). The collection represents a reasonably comprehensive record of ACI during its lifetime and, in most cases, a much briefer synopsis of the life of each of the individual schools, although student rosters and academic records are not present. The overall ACI administrative records consist of minutes, reports, legal and financial documents, correspondence, historical summaries, building plans, studies, surveys, publications, photographs, and ACIN's corporate seal. Records of the individual schools include copies of minutes of the boards of trustees, reports, correspondence, financial documents, institutional histories, personnel records, and publicity materials.
