We have a 14 yo Eagle Scout in our troop and he is every bit worthy of what he has done. I look for our son to make it at about 16....
First, congratulations and good luck to your son. Second, as I said above, there are some exceptions to my general observations about 14 year-old Eagle Scouts.
Your point is well-taken about the young man in your son's Troop.
As a Scoutmaster, I might argue that it's very often not a matter of whether a Scout is worthy of the rank of Eagle at 14. Presumably, any young man who advances through the ranks of Scouting, earns the required merit badges, serves in the required leadership roles, meets the tenure requirements, demonstrates Scout Spirit at each level to the satisfaction of his Scoutmaster, and undertakes and carries out an Eagle Project that is approved by his unit committee and the council committee is worthy of the rank of Eagle; that is, unless his parent(s) actually plan and supervise the project.
My point was simply that among even the best 14 year-old Eagle Scouts, a significant percentage of them would have learned more from their Eagle Project had they undertaken it when they were more mature, in my opinion and observation. Some are mature enough at 14 so that the incremental amount more they would have learned from waiting two or three years is not worth the wait for them to earn the rank.
Again, good luck to your son. You may already know that support from parents appears to be the key factor in young men earning the rank of Eagle Scout; that speaks highly of you (and Mr. or Mrs. MarMema). So thanks to you for supporting your son and Scouting as well.
Many are. Good luck in the days ahead.
