I've often heard it mentioned here about "passing" and "failing" ranks. At the same time, I've heard that the "Scoutmaster Conference" is just a conference -- and it "has" to be signed off when they meet and have the conference, and no SM can ever refuse (or should refuse) a conference.
The Scoutmaster Conference is a "participate in" requirement.
Participate in a Scoutmaster conference.
Other requirements are different.
Demonstrate how to display, raise, lower, and fold the American flag.
Earn 6 merit badges, including 4 from the required list for Eagle.
These type of requirements require the Scout to "do" something. The Scoutmaster Conference is nothing but a chat with the Scoutmaster and once that happens, requirement complete.
