11 year old Scouts should be in their own program. They will focus on becoming First Class/Star in their first year. They are not allowed to do campouts with the older boys, along with other major activities.
Boy Scouts of America run them slightly different than LDS BSA units (mostly age differences, and non-LDS Venture Crews are co-ed).
12-13 Scouts should be focusing on earning their Eagle Scout.
14-15 Varsity Team can work on merit badges and advancement, but focus on team building. They set up a program for each 3 month period, in which they learn things that culminate in a major activity (often sports).
16-17 Venture Crew usually does little in regards to advancement. They focus on life skills, leadership, etc. They will often plan programs regarding different careers, college, etc., preparing them for adulthood.
Varsity and Ventures will have more high adventure activities.
We're finding that older boys are less interested in regular Scouting. If they don't have their Eagle (or most requirements) by the time they are 14, chances are they won't reach it. We are trying to provide older boys activities that are of more value to them at this point. You will often see that if you try a regular troop for all of them, your older boys will stop attending and find high school or other activities to do instead.
