Attaining the Eagle rank is often the end goal of a scout and their parents. It looks good on a resume and shows commitment to a program over an extended span of time. But, just like each rank advancement before it, the Eagle rank is a major advancement milestone, but not the culmination of scouting.
After reaching Eagle, a scout can continue to earn merit badges and be rewarded with an Eagle Palm for each 5 additional merit badges.
They can also continue to lead and guide the troop or they can change their focus to helping Cub Scouts become Boy Scouts. They may become a Junior Assistant Scoutmaster, helping the Scoutmaster with projects to improve the troop. Or, they can look for worthwhile endeavors outside of scouting to which they can apply their scouting background.
There are many ways an Eagle Scout can continue to contribute to and receive from the Scouting program.
