  • Our History, Educating Servant Leaders Since 1893

    Established as "West Texas School for Boys" in 1893 by the Right Reverend James Steptoe Johnston, D.D., the second bishop of the Episcopal Diocese of West Texas. The school's name was soon changed to "West Texas Military Academy" (WTMA), and graduates referred to their Alma Mater as simply "West Texas" for decades.

    General Douglas MacArthur graduated from WTMA in 1897 as valedictorian. He wrote in his Reminiscences (1964) that his Alma Mater is where he developed "a desire to know, a seeking for the reason why, a search for the truth..." MacArthur gained an appointment to the United States Military Academy in 1898, and the rest is an important part of American and world history.
  • Becoming Texas Military Institute

    In 1911, WTMA moved from the the Government Hill section of San Antonio to a new campus in Alamo Heights. In 1926, the upper school of San Antonio Academy and WTMA were merged, the name was changed to "Texas Military Institute," and Dr. W.W. Bondurant, one of the great educators of Texas history, became head of school.

    Women were admitted to TMI for the first time in 1972. One of the first female graduates of TMI was Connie McCombs '74, daughter of South Texas entrepreneur B.J. "Red" McCombs.

    In 1974, the JROTC become optional, and TMI has been a mixed school of civilians and cadets ever since.

    After a one-year hiatus when TMI served grades 9-12 only, an eighth grade was restored in 1954, a seventh was added in 1967 and a sixth in 1973.
  • The Evolution of TMI Episcopal

    In 2004, TMI adopted the DBA name "TMI – The Episcopal School of Texas" to identify the school's historical roots and connection with the Episcopal Church.

    Recognizing the need for a shorter, more pronounced identity, in 2017 the school adopted its common name as “TMI Episcopal.”

    Today, the school educates over 470 students in grades 6-12. Our Corps of Cadets has maintained a long tradition of being designated an Honor Unit with Distinction and the five- and- seven-day residential life programs provide a home away from home for nearly 50 students.

    100% of our graduates go on to college after they have been prepared in a demanding program designed to develop the whole person spiritually, intellectually, physically, aesthetically, and morally.
