What is the order of ranks in boy scouts?

The highest rank a Scout can earn is Eagle Scout. After the Eagle Scout is earned the Scout can continue to earn an Eagle Palm for each 5 merit badges. These are considered "devices" that can enhance the rank, but are not new ranks in themselves (a Scout with several Eagle Palms will still refer to his rank as Eagle Scout). The palms are awarded in the order of bronze, gold and silver after the military tradition of using silver for the highest honors.

The head of the national organization is the Chief Scout.

The highest award that an adult leader be earn is the Silver Buffalo for national level "extrodinary" service to youth. The service does not need to be in association with the BSA.
