The ACI series relating to St. Philip’s School is primarily the ACI director’s correspondence (1921-1937), which details the reasons that St. Philip’s was never made an official ACI school. St. Philip’s publications providing historical background include a brochure (c.1920s) and Opportunity (1923-1924, 1929). Documents relating to ACI’s financial appropriations to the school (1921, 1923, 1931, n.d.), correspondence of the Bishop of West Texas (1921-1922), and a report of an evaluative visit to the school (1926) complete this set of records.
