thanks for the link the advancement guide. this is also in the guide concerning cub scouts.
~~4.1.0.4 “Do Your Bestâ€Â
Cub Scoutsâ€â€even those of the same ageâ€â€may have
very different developmental timetables. For this reason,
advancement performance in Cub Scouting is centered
on its motto: “Do Your Best.†When a boy has done
thisâ€â€his very bestâ€â€then regardless of the requirements
for any rank or award, it is enough; accomplishment is
noted. This is why den leaders, assistants, and parents
or guardians are involved in approvals. Generally they
know if effort put forth is really the Cub Scout’s best.
As far as B&G being used to award all ranks their patches, I completely agree they should be separate. However, this is how our pack has always done it and I'm not likely to change that tradition quickly.
