ISO collects data for more than 47,000 communities and fire districts throughout the country. The data is then analyzed using a proprietary Fire Suppression Rating Schedule. The Schedule then assigns a PPC score between 1 and 10 to the department, with Class 1 representing "superior property fire protection" and Class 10 indicating that an area doesn't meet the minimum criteria set by the ISO. On July 1, 2013, the revised FSRS was released, adding an emphasis on a community's effort to limit loss before an incident occurs. In developing a PPC, the following major categories are evaluated:
Fire Prevention: programs that contain plan review; certificate of occupancy inspections; compliance follow-up; inspection of fire protection equipment; and fire prevention regulations related to fire lanes on area roads, hazardous material routes, fireworks, barbecue grills, and wildland-urban interface areas.
Public Fire Safety Education Programs: fire safety education training and programs for schools, private homes and buildings with large loss potential or hazardous conditions and a juvenile fire setter intervention program.
