WADF 1D
A detailed description of this judging system can be found in the World Artistic Dance Federation regulations.
Elimination round
In elimination rounds, judges evaluate each performance and decide which performances should advance to the next round by giving crosses (X). The number of crosses to give is automatically calculated based on the number of performances in the round or set by the scrutineer or chairman.
Later on, performances with largest number crosses are qualified for the next round.
Final round
In the final round, judges simply rank each performance by assigning unique place from 1 to the number of performances in the round.
Later on, the final rank is calculated using skating system.
