The skating system consists of 11 rules, 10 of which determine the scoring of the final round.judges must mark the number of dance couples specified by the Chairman of Adjudicators whom they decide to advance to the next round. A score of a couple is the number of all "pass" marks over all judges and dances. The couples with the highest score advance to the next round. Usually the number of the couples to enter the next round is known in advance. However in the cases of ties the Chairman decides the number of dancers for the next round
The remaining rules are for the calculation of the final placement of the couples. They involve a formal tie-breaking process. Rules 5-8 are for tallying the final places for each dance separately, rules 9-11 compile the final overall placement of couples in a dance category.
