The more responsibility the Scoutmaster gives his patrol leaders, the more they will respond.
-- Robert Baden-Powell, Founder of Scouting
At every level in Scouting, youth have an opportunity to develop leadership skills. The patrol system teaches youth how to behave as part of a team and how to be a good leader and a good follower.
Of course, troop leaders are there to guide and set an example, but youth feel best about themselves when they have input into decisions and take action to reach their goals. It is also important to review what's been done to learn and do better the next time.
Youth leadership comes in many forms, whether it is setting an example for younger members or issuing instructions to one's patrol to prepare for the next hike. Being in a supportive environment helps build confidence and respect, both of which will help as they grow into young adults.
