Note that Eagle Palms are NOT considered "Ranks" by BSA.  
The Charter and Bylaws in Article X, Section 1, Clause 6, states:

"Ranks. There shall be the following ranks in Boy Scouting: Tenderfoot, Second Class, First
Class, Star, Life, and Eagle. The requirements shall be those authorized by the Executive
Board and set forth in official Scouting publications. Eagle Palms may also be awarded on
the basis of requirements authorized by the Executive Board and set forth in official Scouting
publications."

After becoming an Eagle Scout, you may earn Palms by completing the following
requirements:

1. Be active in your troop and patrol for at least 3 months after becoming an
Eagle Scout or after the award of your last Palm*.

2. Demonstrate Scout spirit by living the Scout Oath (Promise) and Scout Law in
your everyday life.

3. Make a satisfactory effort to develop and demonstrate leadership ability.

4. Earn five additional merit badges beyond those required for Eagle or last
Palm.**

5. Take Part in a Scoutmaster conference.

6. Complete your board of review.

You may wear only the proper combination of Palms for the number of merit
badges you earned beyond the rank of Eagle. The Bronze Palm represents 5
merit badges, the Gold Palm 10, and the Silver Palm 15.

* Eagle Palms must be earned in sequence, and the three-month tenure
requirement must be observed for each Palm

**Merit Badges earned any time since becoming a Boy Scout may be used to
meet this requirement.

NOTE: Scouts who earn three Palms may continue to earn additional Palms in
the same order - bronze, gold, and silver. All requirements for Eagle Palms
(except Requirement 6) must be completed before a candidate's 18th birthday.

Requirement 6 - (Complete your board of review)
MAY be done AFTER the
Scout has reached age 18.
