7.0.4.5 Earning Eagle-Required Merit Badges for Star or Life Rank
Candidates for Star or Life, in the selection of “any four” or “any three,” respectively, of the merit badges required for Eagle, may choose from all those listed, including where alternatives are available: Emergency Preparedness OR Lifesaving; Cycling OR Hiking OR Swimming; and Environmental Science OR Sustainability. For example, if a Scout earns Cycling, Hiking, and Swimming, all three of them count as Eagle-required for Life rank. Only one, however, would serve toward the required merit badges for the Eagle Scout rank. The other two would count toward the optional merit badges required to make up the total of 21 merit badges.
Note that Star and Life requirements each allow two non-Eagle-required merit badges. It is the Scout’s decision, however, to earn more—or all—of the merit badges for the Star and Life ranks from the Eagle-required list.
