Insurance Services Office (ISO) Rating

ISO stands for Insurance Services Office. A rating schedule was developed by the Insurance Services Office (ISO). This rating schedule serves insurance companies that cover property and casualty benefits for their clients. ISO representatives use the rating schedule when surveying a community's fire protection capabilities. The ISO scores fire departments on how they are doing against its organization standards to determine property insurance costs. Most home and business insurers use PPC scores to determine insurance premiums. Businesses and individuals in a community with a good PPC score typically pay less for fire insurance. ISO rating system is from 1 (the best) to 10 (the worst).
