The Insurance Services Office Public Protection Classification (PPC) Program plays an important role in the underwriting process for insurance companies. Most U.S. insurers, including the largest ones, use PPC information as part of their decision making process when deciding what insurance to write, coverage to offer, or price to charge for personal and commercial property insurance. Communities whose PPC improves may receive lower insurance prices. A PPC rating of 1 is the best possible rating and recommends the lowest insurance rates. The PPC also provides fire departments with common benchmarks or performance indicators and is used by many departments as a valuable tool when planning, budgeting, and justifying fire protection improvements. ISO is the leading supplier of data and analytics for the property/casualty insurance industry and collects and evaluates information from communities in the United States on their structural fire suppression capabilities. ISO analyzes the data using the Fire Suppression Rating Schedule, and assigns a Public Protection Classification number to the community. ISO’s PPC program evaluates communities according to a uniform set of criteria, incorporating nationally recognized standards developed by the National Fire Protection Association and the American Water Works Association.
