The National Board of Evaluators is made up of Interpreters, Education Officers and Evaluators from each Province.

The Provincial Association represents each Province on the Board as an appointee, while some others are selected by the Chairman of the National Board. The object of the Board is to insure consistency in mechanics and rule interpretations for National and other high profile Championships. Many of the Provinces have adopted the CABO mechanics for consistency across the country. The National Board meets to review and endorse specific mechanics and other aspects as they relate to the Canadian game.

Any Province wishing the services of a National Evaluator at any High Profile Provincial Tournament can apply to the Board Chairman and CABO will appoint a member of the Board to attend the tournament. Verbal and written evaluations are provided for each Official seen.
