Porter-Gaud traces its history to October 1867, when the Reverend Dr. Anthony Toomer Porter founded the Holy Communion Church Institute to educate children orphaned or experiencing poverty in Charleston. The school later became the Porter Military Academy and moved in 1879 to the grounds of the old Federal Arsenal in downtown Charleston. In 1964, the PMA trustees merged with the Gaud School and the Watt School to create the current Porter-Gaud School, which then sold its campus and moved to its present location on the banks of the Ashley River. The school integrated in the 1967-68 school year and welcomed its first female students in 1972-73. In 2008, it expanded through the acquisition of the O'Quinn School. The school's founding principle is the acronym WATCH - Words, Actions, Thoughts, Character, and Habits - and its mission is to inspire lives of purpose, learning, and service through cultivating each student's God-given potential.
