excerpt from the New Parent Orientation Guide on the official scouting website:
Uniform—Like most sports teams, Boy Scouts wear a uniform. Like most sports teams, we expect our Scouts to wear the uniform when they are doing Scouting, and to wear it properly. It is a symbol of who we are and what we do.
...I guess 'expect' doesn't necessarily imply 'require'.
Quote from FAQ on Uniforms and Insignia for CubScouts:
At minimum, each boy in Cub Scouting will need a uniform and a handbook. Each year, the handbook changes, as does the cap and neckerchief, but other uniform parts remain the same for at least the first three years. When a boy enters a Webelos den, he may need to obtain a new uniform if the parents in the den opt for the khaki-and-olive uniform.
AS one might expect, my advancement procedures book is not available to consult, and the link I have for the official BSA BOR training module is no longer valid (?) so I'll just have to take your word WV that if I'm challenged on this I'll have to back down...
WHY would the BSA not require the uniform at a BOR when they 'expect' it at scouting functions. Perhaps I should just communicate that word to the boys too - "I EXPECT you here in full dress Class A uniform for your BOR."
...and we'll EXPECT them to comply.
