"Ranks. There shall be the following ranks in Boy Scouting: Tenderfoot, Second Class, First Class, Star, Life, and Eagle. The requirements shall be those authorized by the Executive Board and set forth in official Scouting publications. Eagle Palms may also be awarded on the basis of requirements authorized by the Executive Board and set forth in official Scouting publications."
