In my troop, when a scout earns a rank or merit badge, we recognize them (announce what they earned, congratulate them, give them some applause) at the next troop meeting so that the accomplishment gets immediate positive recognition for the scout. We award them the physical items at our quarterly CoH.
For Eagles, after their Board of Review and once we have been given word that they passed, we recognize them (like above) but maybe with a little more fuss at the next troop meeting because it’s a big deal to earn Eagle.
Scouts in our troop that earn Eagle hold their own Eagle COH, separate from our regular ones. It’s a much more formal ceremony and usually a catered event that’s put on by the Scout and his family. Nothing fancy or overly expensive - it’s often held at our Town Hall Community Room - but it’s treated as the special occasion that it is.
If there is a quarterly COH before the Eagle COH, we’ll recognize the scout there as well, because again, it’s a big milestone to earn Eagle, but the Eagle Rank ceremony is not performed here nor do we present the medal/patch/certificate.
Of course, if the Scout preferred that we did his Eagle ceremony at our regular COH, we would certainly do that and turn it into an Eagle CoH. It’s not a troop requirement that scouts plan and host their own Eagle CoH. That’s just what the scouts in our troop have historically done.
Covid obviously throws a monkey wrench into all of this due to restrictions on indoor venues, but we also haven’t had a scout need an Eagle CoH since last summer. I have two scouts currently working on their Eagle requirements but they still have enough to finish that they likely won’t have to worry about planning an Eagle CoH while our county is a covid hotspot.
