On July 3, a teaser video was released, revealing the show's title to be World Klass.[4] The 20 trainees were introduced starting on July 10.[5] The show premiered on October 4.

On December 6, the top 10 winners were announced through the live finale.[6] Two days later, n.CH announced that Han Jun, who made it to the final lineup after placing third, would not be joining the group due to partaking in an unauthorized leave and disreputable scandal when he was a trainee. He was replaced by Jae Yun, who had the next highest number of votes on the show.[7]
