Dancing with the Stars (American season 20)

Ten professional partners were revealed on February 11, 2015, on Good Morning America.[4] Joining Lindsay Arnold, Sasha Farber, Henry Byalikov and Jenna Johnson in the troupe this season were Brittany Cherry and Alan Bersten (from the tenth season of So You Think You Can Dance). Eleven of the celebrity competitors and their professional partners were revealed on Good Morning America on February 24, 2015.[3] Witney Carson's celebrity partner was reported to be Chris Soules from The Bachelor on March 4, 2015; Soules later confirmed to be on the show on March 10, nearly 12 hours after that show's finale.[5][6] At the age of 14, Willow Shields was at this point the youngest contestant ever to compete on the show[7]

Tom Bergeron returned as host alongside Erin Andrews. Len Goodman, Carrie Ann Inaba, Julianne Hough, and Bruno Tonioli returned as judges.[7]

The best and worst performances in each dance according to the judges' 40-point scale are as follows:

Scores are based upon a potential 40-point maximum.

Couples performed the cha-cha-cha, foxtrot or jive. Couples are listed in the order they performed.

Couples performed one unlearned dance representing a different historical era.[23] The couple with the highest score earned immunity from elimination, while the rest of the couples participated in dance-offs for extra points. For each dance-off, the couple with the highest score picked the opponent against whom they wanted to dance; the chosen opponent was allowed to pick the dance style (from cha-cha-cha, foxtrot, or salsa). The winner of each dance-off earned two points. For winning immunity, Nastia & Sasha received a three-point bonus. The Charleston was introduced. Couples are listed in the order they performed.

Couples performed a routine featuring an unlearned dance and song that was chosen by the public, as well as a trio dance involving an eliminated pro or a member of the dance troupe. Couples are listed in the order they performed. Two couples were eliminated at the end of the night.

Couples performed one unlearned dance, and as a routine coached and styled by one of the four judges. To avoid favoritism, the judges did not score the couple they coached, so the second round dances received a total score out of 30 instead of 40.[26][27] Couples are listed in the order they performed.

On the first night, couples performed a dance they previously performed, as well as a freestyle routine. On the second night, the couples danced a fusion dance of two previously learned dance styles. Couples are listed in the order they performed.
