General Handbook Information
CARO has two distinct areas of competition - the Original area, which includes Novice, Advanced, Excellent and two levels of Versatility, and Working. The latter is further split into two areas.
Each level of competition has its own rules and regulations, although the Master General Handbook which relates to the original area of competition, also has some control over the other two levels.
You may find the Handbooks for all levels here.
