The FCI has published Judging Guidelines which will be valid as of 1 January 2018.

These “Judging Guidelines” are meant to help judges in FCI member countries to come to the same understanding/interpretation of the rules. The Guidelines do not intend to change existing rules or to be in contradiction with them, but they should help to clarify the gaps in interpretation left by the wording and/or drawings in the rules. The application of these Guidelines is compulsory at FCI events such as the World Championships, the European Open, the Junior Agility European Open and CACIAg competitions. It is recommended by the FCI that FCI member countries apply the Judging guidelines and implement these recommendations in national agility events.
