The scoring was altered for the "all-star" season 15, during which judges could give scores at 1/2-point intervals from 0.5 to 10, for a total score of 1.5 to 30.
When multiple performances are scored, only the cumulative total counts.
It is the US version of the UK series Strictly Come Dancing.
The show is hosted by Tom Bergeron, alongside Erin Andrews, who became co-host in season eighteen.
Several former contestants appeared as judges in episode 200 (in season 11), including Hélio Castroneves, Mel B, Drew Lachey, Gilles Marini, Kelly Osbourne, and Emmitt Smith.
Other celebrities, most often those who are associated with the world of dancing, former professional dancers, and past contestants have appeared as the fourth judge or in absence of one of the main judges, including Paula Abdul, Donnie Burns, Nick Carter, Cher, Maksim Chmerkovskiy, Michael Flatley, Kevin Hart, Jessie J, Rashad Jennings, Baz Luhrmann, Ricky Martin, Idina Menzel, Abby Lee Miller, Mandy Moore, Olivia Newton-John, Kenny Ortega, Donny Osmond, Pitbull, Redfoo, Alfonso Ribeiro, Robin Roberts, David Ross, Shania Twain, and Zendaya.
In several cases where ESPN coverage of Monday Night Football airs instead on an ABC affiliate in an NFL team's home market, the program is delayed to air immediately after that station's local news, Jimmy Kimmel Live, and Nightline, and a voting window confined only to the area codes of the pre-empted market is opened up to allow affected viewers to still put their votes in for the competition, though this is on a market-by-market basis (in some markets, an alternate sister station or digital subchannel carries the program live as scheduled).
Seasons 1 and 3 featured only two couples in the final week instead of three.
The couple receiving the lowest combined total of judges' points and audience votes is eliminated each week until only the champion dance pair remains.
