An even or odd number of judges may be used for callbacks in preliminary and semifinal rounds. Half the judges selects leaders and half selects followers.
An odd number of judges will be used in all final rounds to minimize the possibility of ties. A minimum of 5 judges is required; 7 or 9 judges are even better.
Preliminary and Semifinal Rounds
In the preliminary and semifinal rounds, a callback system is used. In this system, each judge selects individuals for callback to the next round but does not rank them in any particular order.
The Scorer converts each judge’s selections into points. 10 points for all selected individual, 5 thru 1 points for any alternates 1 thru 5, and 0 points for all not selected. Contestants are then ranked according to the total points sum.
After the judges’ scores have been tallied, the Chief Judge determines how many individuals, or couples will be promoted to the next round.
The Chief Judge’s scores are used only to break ties.
Tallying the Final Placements
In the finals, each judge must place every couple in rank or order (1st place, 2nd place, 3rd place, etc.). In a final with a large field of couples, the judges will concentrate on placing the top twelve couples.
Duplicate placements are not permitted. If a judge mistakenly provides duplicate placements, the Chief Judge will request that the judge provide unique placements for each couple.
A couple must have a majority of judges’ votes to be awarded a final placement.
If no couple has a majority of votes, then the next placement is added to the previous placements (1st through 2nd, 1st through 3rd, etc.) until a majority is reached.
If there is a tie, a larger majority beats a lower majority (for example, 5 votes beat 4 votes).
If two or more couples have an equal majority (such as 4 votes each), then the next placement is added to the previous placements for those tied couples only.
If two couples remain tied through all placements, then each judge’s placements for only those two couples are compared. The couple with a majority of higher placements wins.
The Chief Judge’s scores are used only to break any remaining ties.
