Cub Scouting happens in the den. The National Den Award creates an incentive for a year-round, fun, quality program in the den. The National Den Award may be earned only once in any 12-month period. (charter year or calendar year, as determined by the pack committee).

Once completed, hand it into your Council for processing.  And congratulations on having a Quality Den Program that lasts year round that Cub Scouts want to come back to again and again.
