Remember, there are no performance requirements for a boy. Simply participating and doing one's best in an activity constitutes completion of the task.
The highest rank in Cub Scouting is the Arrow of Light Award (see above). Earning this rank prepares a Webelos Scout to become a Boy Scout. Webelos Scouts who have earned the Arrow of Light Award have also completed all requirements for the Boy Scout badge.
This award is the only Cub Scout badge that can be worn on the Boy Scout uniform when a boy graduates into a troop. Adult leaders who earned the Arrow of Light Award when they were young may also show their achievement by wearing a special square knot on their adult uniform.
Learn about the Arrow of Light requirements, or refer to your Webelos book.
