Prior to the new requirements, when the majority, but not all, of the scouts were able to complete they rank awards by Blue and Gold; we held a themed ceremony that matched the Blue and gold theme.
When we had a pirate theme, they walked a plank - jumping off into the unknown,
When we had a Lego theme, they each took a (quatro - oversized lego) brick and built up a sturdy wall as they crossed the stage.
When we had a spy theme, the scouts were all graduating spy school and received a dossier (that also included their ranks).
Under the new program, we are planning to hold more of a court of honor, since ranks would not be done at the B&G.
This does not, have to be a dry affair. Choose a theme, and then build a fun ceremony the Scouts will remember around that theme.
There are a lot of on-line resources available for "meaningful ceremonies" as well, in fact, I'm taking that class this weekend at our University of Scouting. (never too old to learn new ideas)
The real key is to individually recognize each Scout's achievement, call out their names. If you are smart, you also plan for the Scouts' parents to take a photo as their child receives the award.
Do not confuse this plan with making the Scouts wait for award ceremony to get the ranks. If they complete early, they get the award early, at a separately themed (to match the pack meeting) ceremony. They will then be re-recognized at the larger awards ceremony. Likewise scouts who do not complete, still got to do the march, and instead received an "almost there, good job and keep it up" type award.
And welcome to the forum, thank you for what you do for our Scouts.
