Since Arthur Eldrod became the first Eagle scout in 1912, the rank has represented a milestone of accomplishment, perhaps without equal, that is recognized throughout the country and even the world. Men who have earned the Eagle scout rank count it among their most treasured possessions. "Eagle Scout" is not just an award; its a state of being. Those who earned it as boys continue to earn it everyday as men. This is why an Eagle scout IS an eagle scout- not was.  

Attaining the Eagle rank is often the end goal of a scout and his 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.

He can also continue to lead and guide the troop or he can change his focus to helping Cub Scouts become Boy Scouts. He may become a Junior Assistant Scoutmaster, helping the Scoutmaster with projects to improve the troop. Or, he can look for worthwhile endeavors outside of scouting to which he can apply his scouting background. 
There are many ways an Eagle Scout can continue to contribute to and receive from the Scouting program.
