The Verdict
Saint Thomas Academy is Minnesota's only all-male Catholic military school. Founded by Archbishop John Ireland in 1885, STA operates on four pillars—Catholic faith, academic excellence, military leadership, and an all-male environment.
The result: a 100% college acceptance rate, an average ACT score of 28, and alumni who include a Medal of Honor recipient, a Supreme Allied Commander, an SEC chairman, and Minnesota Supreme Court justices. Daily formation, the Fleming Saber tradition, and 25,000 annual hours of community service define a culture where boys become men of character.
