In 1972 all ten corps from the Midwest Combine and the Alliance—plus the Anaheim Kingsmen, Argonne Rebels, and De La Salle Oaklands—were founding members of Drum Corps International, which remains the sanctioning body for junior corps in North America. At the first DCI World Championships in Whitewater, Wisconsin, the Scouts finished in fourteenth in a competition that featured thirty-nine corps from the East, the South, the West Coast, the Midwest and Great Plains, and Canada. In 1973, the Scouts rose all the way up to fourth place. The following year they were DCI runners-up, and in Philadelphia in 1975, the Madison Scouts became the third corps to win the DCI World Championship. Throughout the 1970s the Scouts became regulars in CYO Nationals as well, making Finals in 1973 through 1979 and winning in 1974 and 1975.
