I have never encountered anyone who has asked a group of young men whom among them was an Eagle Scout and then follow-up by asking about Palms.
I don't know anyone who was not involved in Scouts who knows there is something called an Eagle Palm.
I have rarely met an Eagle Scout who talked about how many Palms they earned after getting their Eagle Scout award. Those that do, tend to have more than three and what they're really bragging about is the number of merit badges they earned.
Eagle Palms are a bit of a throwback to the old Star, Life and Eagle ranks - for those unfamiliar with the history, Star, Life and Eagle were not originally ranks like Tenderfoot, Second Class and First Class. First Class was the highest rank you could get. Star, Life and Eagle were awards for getting Merit Badges. The Life badge came first and was awarded to First Class Scouts who earned First Aid, Athletics, Lifesaving, Personal Health and Public Health merit badges. Star was next just for earning another 5 merit badges. Eagle Scout was awarded when 21 merit badges were earned (and now you know why Eagle Scouts have to earn 21 merit badges).
When Star, Life and Eagle Scout were made ranks, Palms were developed as the new merit badge awards.
I'm really not all that opposed to any of these changes. Lets remember what the Merit Badge program is really for. Other than the 13 required for Eagle badges, this part of the program is really designed for Scouts to explore vocations and avocations that they might carry over in to adulthood, or the learn more about subjects that they might be interested in. While earning them all might sound impressive, I question whether the Scouts that earned them all really learned anything from them. The idea behind palms was to encourage Scouts to keep earning Merit Badges which continues to contribute to a Scouts personal growth. If a Scout has earned 20 merit badges beyond what they need at Eagle, what motivation do they have to earn more if they can just hang out exhibiting leadership in 3 months increments and earn 4 palms in a year.
I'd be much more impressed if instead of banking on merit badges they already earned, they earned the merit badges for palms while they were Eagle Scouts. To that end, how about creating a second set of "palms" - maybe an Oak Leaf - to differentiate additional merit badges earned before Eagle Scout and those earned After. If you earned 15 additional merit badges before Eagle Scout, you get a Bronze, a Gold and a Silver Oak Leaf (or maple, or elm, or cottonwood) award and those earned after Eagle Scout earn Palms?
I agree with eliminating the BOR - for most units, it's hard enough to schedule a BOR for regular ranks, let alone Palms. Lets remember the main purpose of a BOR - it's not to test Scouts, its to see how the Scout is doing, what they like about the Troop, what they like about the Program. While all that can be learned in a good Scoutmaster Conference, the BOR is the committees opportunity to hear it first hand. By the time a Scout is an Eagle Scout, the committee is already going to have a pretty good idea of what a particular Scout enjoys and doesn't enjoy, and how a particular Scout thinks. Is there really any more value to hearing from them every three months thereafter? A Scoutmaster Conference should be more than sufficient for Palms.
Frankly, I'd have no problems just eliminating the time in service requirements altogether. Unless you're dealing with a super-scout, I suspect most Scouts will take about 3 months to earn 5 more merit badges anyway.
I recognize that change is something that is never accepted readily but after the initial "they've done it again" eye-rolls and complaints, I suspect that things will settle in and in a couple of years, most of us will have forgotten how it was once done until a parent or a new leader comes on to the board and asks why some Scoutmaster or Advancement Chair is insisting on using the old rules for Palms.
