OK, looks like this has been discussed in the past but I do not see a direct answer to my question, so I ask the wisdom of the group:
We all agree (at least I do!)that scout POR for Star and above require satisfactory performance by the scout in the POR. However, our troop in the past established specific guidelines intended to remove subjectivity. These include rather specific requirements to attend high percentages (75-90% depending on POR) of meetings, campouts etc. If the scout attends less, does not turn in self evaluations, does not attend troop leadership training etc. partial cred
