Colonel Carroll Andrew Edson was an influential leader in the Boy Scouts of America movement. He helped to found the Order of the Arrow (OA) along with E. Urner Goodman. The OA is an official program of the Boy Scouts of America designed to recognize Scouts and Scouters for their service, and to aid in the retention of older boys in the Scouting program.

The Order of the Arrow (OA), previously known as Wimachtendienk Wingolauchsik Witahemui (WWW) is the honor society of the Boy Scouts of America (BSA), composed of Scouts and Scouters who best exemplify the Scout Oath and Law in their daily lives as elected by their peers. Started as a Camp Fraternity by E. Urner Goodman, with the assistance of Carroll A. Edson, in 1915, its goal was to reinforce the Scout Oath and the Scout Law. Started without approval of Boy Scouts of America (BSA), it became an "Official Experiment" of the scouting organization. In 1948, following an extensive review, it officially became a program of Boy Scouts of America.
