First Class
First Class is the fourth rank in Scouts BSA. A Scout can complete requirements for any other rank in virtually any order, but the ranks must be earned in sequence (Scout, Tenderfoot, Second Class, First Class, Star, Life, and Eagle). To earn the First Class rank, a Scout must complete requirements dealing with orienteering, camping, cooking, constitutional rights, plants, knots, lashings, swimming, recruitment, and the Internet.
Star
Star is the fifth rank in Scouts BSA. The requirements for the Star rank are much different than the previous ranks. To earn the Star rank, a Scout must be active in their Troop and Patrol for at least 4 months after earning First Class, earn 6 merit badges, including 4 from those required for Eagle, complete service projects totaling at least 6 hours of work, and serve in a leadership position in the Troop for at least 4 months.
Life
Life is the sixth rank in Scouts BSA. The requirements for the Life rank are similar to those of the Star rank. To earn the Life rank, a Scout must be active in their Troop and Patrol for at least 6 months after earning Star, earn 5 additional merit badges beyond those earned for Star (total of 11), including 3 more from those required for Eagle, complete service projects totaling at least 6 hours of work, and serve in a leadership position in the Troop for at least 6 months.
