Hello, There are three adult leaders in our son's troop. One of the scout is one of the troop leader's son. Since the new troop leader joined the group, most of his son rank's requirement have been signed by him. One of the leaders also has a son in the troop but his son's rank requirements have always been signed by the other leader. We parents wouldn't notice or be curious if the new troop leader's son didn't advance two ranks in the same amount other scouts advanced to one. And we know that his son is not lazy but not extremely motivated either. Is there a rule or restriction on unit leader sign off on his/her own son's rank requirements.
