Criteria for selection for ISU championships
Ice Dance
For Europeans: at the end of National Championships, the ranking is computed by summing the score of Nationals and the average of the two best scores achieved in international competitions (theoretically it also says national competition but no relevant couple is doing national competitions).
For Worlds and Junior Worlds: at the end of Egna Dance Trophy, the ranking is computed by summing the score of Nationals, the average of the two best scores achieved in international competitions (excluding Egna Dance Trophy) and the score of Egna Dance Trophy
If a couple can't attend Nationals, they can use another score (national or international).
Guignard/Fabbri (top 5 in an ISU Championship last season) can skip Egna and use another international score.
Single and Pairs
well, that's a bit confusing. Italian Federation outdid ISU and published a document with various cut and paste not properly edited making some sections quite confusing.
For Europeans: at the end of National Championships, the ranking is computed by summing the score of Nationals and the top 2 international (or in national competitions approved by the federation council) scores
For Worlds and Junior Worlds: at the end of European Championships, the ranking is computed by summing the score of Nationals and the top 3 international (or in national competitions approved by the federation council) scores. One score must be from an event taking place after Nationals.
And now the not so clear part.....I gather that scores from Nationals; ISU events and Challenger Series count fully while others count 90%. Not so clear because it refers to point 1 (which have some cut and paste issues). It seems international B events count 90%.
