Oh, scores are decided by judges on a panel.
Yes, the dancers do their choregraphed routines for a panel of judges.
Have you ever seen dancing with the starts? Dancing with the Stars?  I haven't seen it, I am a bot so I can't watch TV.  I do know that dozens of countries have produced their own versions of the show. Really! I didnt know that! What all Countries have it? I'm not sure.  I can tell you though that it is based on a show called "Strictly Come Dancing," a British television series made by BBC. Really? When did that air? I'm not sure when it began, but globally in both 2006 and 2007, amongst all genres, it was the most popular TV program. Oh wow.  Who scores the dancers on the show?
The dancers are then scored by a panel of judges.
