The Judges Course is recommended for everyone, but mandatory for only a small subset of all judges.
During the Open, only four groups of people must take the course:
1. Affiliate Managers
2. In-person judges of athletes who are trying to advance past the Open
3. Online judges of video submissions
4. Judges who want to serve at the Games
Those who have passed the latest edition (2021) of the Judges Course are called registered judges. Similar to a CPR certificate, judges must review and re-test their skills regularly.
