Events only qualify if there was at least a semi-final danced.
As always, points are awarded to both members of the couple, and couples must always dance to the higher level of the two competitors. Also note that these are national policies and all competitions are not required to follow these. However, if a competition states that they are following YCN proficiency points, then this is what shall be used. Unfortunately, I didn't keep the program which had this system outlined, so I don't know what they called the system. So anyway, they're different manifestations of the same principle.
