The Scoutmaster is the adult responsible for working directly with the Scouts providing direction, coaching, and support. The Scoutmaster has three basic roles:
providing the junior leaders with the tools and skills so they can run the troop;
making sure the rules of the BSA and chartered partner are followed; and
being a good mentor and positive role model.
An assistant Scoutmaster is an adult leader over the age of 18 who helps the Scoutmaster deliver the promise of Scouting. Each assistant Scoutmaster is assigned specific program duties. They can serve the troop by guiding a particular patrol to which they’ve been assigned, advising certain Scouts who’ve assumed a position e.g. the quartermaster or OA representative, or fill in as necessary to assure the junior leaders have what they need to run things.
