As scoutmaster, it is my experience that once a scout gets to high school, it gets harder and harder to make time for scouting. I believe that if a scout wants to make Eagle, they should shoot to make it by age 16. I have seen it done by 14, which is amazing. I have seen scouts wait till the day before their 18th birthday, which is nerve racking!   The chart below shows different paces to make Eagle.  I encourage scouts to look this over, and see how they are doing.   I also encourage parents to discuss with scouts their progress, and help them keep on track.
