Open auditions for this season were expanded to the following six cities:
For the first time, New York City was not a stop on the audition tour. To be able to audition, contestants had to be between the ages of 18 and 30 and able to be legally employed in the United States. Partner auditions were allowed.
Because of the inclusion of performer Will Wingfield into the top 20 dancers, Debbie Allen was ruled ineligible to perform duties as a Guest Judge during the Finals phase, as long as Wingfield remained in the competition. Wingfield is a Contemporary dancer from Nashville, Tennessee who trained under Allen at the Debbie Allen Dance Academy. He was voted off the competition on July 24, 2008. Because of Wingfield being eliminated, Debbie Allen was technically able to guest judge for the top six episode, but Adam Shankman was the guest judge instead.
†There was no bottom 4 this week
‡Katee Shean was awarded $50,000 for being America's favorite female dancer.
