Earning Eagle Palms
After successfully completing your Eagle Scout board of review and being validated as an Eagle Scout by the National Service Center, you will be entitled to receive an Eagle Palm for each additional 5 merit badges you have completed before your Eagle Scout board of review.
A Scout can be recognized with an Eagle Palm(s) for the extra work he has put into earning merit badges prior to earning the rank of Eagle Scout.
The right way to wear a combination of palms
The Bronze Palm represents the first five merit badges beyond the 21 required for Eagle. The Gold Palm represents the next five (10 total), and the Silver Palm the third five (15 total).
After that, you’ll combine multiple Palms. While qualifying Eagle Scouts can wear multiple Silver Palms, they should never wear more than 1 Bronze or 1 Gold Palm. You’ll see why in this handy chart that shows the proper Palm combinations.
