By 1925, the interest in the organization had become so great that it needed to be split into six divisions. These divisions included the Eastern Ski Association, Central Ski Association, Western Ski Association, Arrowhead Ski Association, California Ski Association, and the Pacific Northwestern Ski Association. All six of these divisions were governed by the National Ski Association. Outside of this organization, the national organization had affiliations with the International Federation De Ski, and various other ski, Olympic, and recreation organizations.
