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 Regional-caliber athletes
3. Online judges of video submissions
4. Judges who want to serve at the Regionals or the Games
Those who have passed the latest edition of the Judges Course are called registered judges. Similar to a CPR certificate, judges must review and re-test their skills regularly. CrossFit requires that judges take and pass the course each year.
