After an organization drive that began in 1905, the Southwest Texas Baptist Conference established the school in 1907 by matching $25,000 raised by citizens of San Marcos. James Milton Carroll, a leader of the founding campaign, served the Academy as its first president. The school enrolled an entering class of 200 students on September 24, 1908. Carroll resigned in 1911; the Academy's original building, granted a state historical marker in 1970, became known as Carroll Hall. Thomas Green Harris succeeded Carroll, and the Christian Education Program of the Baptist General Convention of Texas began administrative oversight in 1911. After the United States entered World War I in 1917, the federal government granted the Academy a junior unit of the Reserve Officer Training Corps. For a time all male students were require to have served in the corps of cadets, and all those in grades nine through twelve are formally enrolled in the army Junior ROTC program, but it is no longer required. Girls have also participated in military training on an optional basis since 1973 when two students, Mary Shepard and Karen Stubbs led the development of the first female platoon. By 1936 the Academy's physical plant had increased to twelve buildings on a fifty-six-acre site valued at $400,000. Students in grades one through twelve studied general academic courses as well as fine arts and business subjects. In 1968 more than 500 students in grades three through twelve attended the Academy; in 1986 the enrollment was 240 boys in grades six through twelve and 120 girls in grades nine through twelve. Also in January 1982, under the administration of Jack E. Byrom the Academy moved from its location at the current Texas State University campus, to a more spacious lot on Ranch Road 12. The Academy has had students from a number of other states and foreign nations. Most Academy students reside in dormitories on campus and attend mandatory chapel services on Wednesdays, and devotionals on Mondays. Chapel services are currently optional for both boarding and day students, taking place at First Baptist Church on Sunday. Since the school's beginning, the Academy has accepted students from all religious faiths. Students of both sexes have competed in athletic events against other private schools. The academy is a member of the Texas Christian Athletic League and is accredited by the Independent Schools Association of the Southwest, the Southern Association of Colleges and Schools, the Texas Education Agency, and the accrediting commission of the Texas Association of Baptist Schools. A fifteen-member board of trustees selected by the Baptist General Convention of Texas continues to govern the Academy. Thirty-five full-time and twelve part-time teachers composed the faculty in 1993; three administrators supervised Academy operations. That year the endowment of the academy exceeded $3 million, and the institution's assets exceeded $15 million. After selling its original site and buildings to Southwest Texas State University in 1979, the Academy moved to its present site.
