Scouts work on their rank advancements individually, but with the full support of the Troop scouts, adult leadership, and their parents/guardians.
Scouts primarily work through their Scoutbook during their Scout, Tenderfoot, Second Class, and First Class ranks. As a scout learns and then masters each new skill, they can have any First Class, Star, Life, or Eagle Scout test mastery and sign-off the completion of the skill development.
Once a scout completes all the requirements for their current rank advancement, they will need to request a Scoutmaster Conference, and then a Board of Review.
