ISO wanted fire departments to conduct 20 hours of training per man, each month, in order to maximize points for every training aid. Historically, very few cities ever received a "Class 1" rating. There have been times where only one city, out of the nation, would receive a "1". Presently there may be as many as 40+ cities with a "1" rating in the U.S. This is still a small percentage when one considers the thousands of communities nationwide.
