Thank you all for your comments and suggestions. I understand the policy breach and will no longer retest in that setting. I will, however, find a way to maintain quality checks throughout the rest of the program. As I wrote before, the scouts do teach each other scoutcraft and have many opportunities to practice or demonstrate their skills either at troop meetings or on monthly campouts. Some specific responses follow:
to scoutldr: the scouts in my troop truly have fun. the knot board is an excellent example. the boys will vie for position in line to have a turn at being timed for the king knot. they cheer each other on and will most definitely point out an erroneously tied knot. since I provide scenarios rather than rot testing, they don't realize that it is skill testing.
to wingnut: I have a bond with all of my scouts from the first day the visit as a Webelos scout. I have chats with the boys at any opportunity. I see it my duty to understand what is going on. For instance, one boy who many of the adults in the troop had written off as trouble, was having difficulty dealing with divorce. He talked to me in his own time and fashion because I treated him with respect and understanding. Afterward, the discipline problems disappeared.
to eammon: recently, there was a headline about an eagle who have been accused of murder in a small town. The openning sentence read something akin to honor student, star athelete, etc. is accued of murder. The headline, in bold enlarged print, had another purpose; shock value. Why do you suppose that the writer chose that headline? In my opinion, he knew that the accolade "Eagle Scout" has the connotation of honor and excellence. Why is it that the US military academy applications have a single question about scouting, namely: Are you an Eagle scout? I don't demand excellence. I don't even ask for it. I trust the scouts, and anybody else for that matter, to demand excellence of themselves.
to mk9750: I trust my SAs to ensure quality when signing requirements and have no need to remove them from the process. However, I do think that one of the improvements I can implement is a more rigoruous review program with them. (Thank you for observance of the 5th scout law!)
to scoutingagain: your description of the BOR smacks slightly of retesting when you ask for a demonstration of skills. My understanding of the mechanics of the BOR is that the board should ask open-ended questions that give the scout an opprotunity to discuss his accomplishments that lead to this rank. also, a BOR may determine that a scout is not ready for rank. If the board is not unanimous, they must detail the issues and corrective actions in a written report. This report is then reviewed with the scout and scoutmaster. This is not a failure per se, but the scout would not advance until the next BOR. The only other condition for "failure" would be due to poor bookkeeping, especially when up for eagle.
to all: I reiterate that I will no longer be re-testing the scouts in conference. I will continue to "lead by example" by requiring excellence in my actions. I will implement a program of quality checks in my SAs and scout instructors holding them to the highest standard. Again, thank you for your comments and suggestions.
