ISO Rating


The Insurance Services Office (ISO) surveys communities on a regular basis to determine the Public Protection Classification for the fire protection services protecting the community. The Public Protection Classification is used to gauge the ability of a local fire department to respond to fires. A community's fire protection information is collected and analyzed by ISO using its Fire Suppression Rating Schedule.

A classification of 1 to 10 is then assigned based upon the results of the survey. Class 1 is the best rating, and Class 10 is basically an indication of no fire protection. The ISO Public Protection Classification is used by the insurance industry in determining insurance premiums for many properties within the community.

Target Areas

A variety of areas are examined when ISO conducts their survey. They look at the community's water supply, dispatch (communications) center and fire department. Each entity receives a rating, and in the end those ratings are considered together to determine the final Public Protection Classification.

As a result of the ISO Survey conducted in 2013, the Town of Normal has maintained a Class 2 rating. ISO has collected information from approximately 46,700 jurisdictions across the nation. On the ISO website, 453 jurisdictions are rated as Class 2, and only 48 communities are rated as Class 1. This puts Normal in the top 1% nationwide.


The Normal Fire Department is proud to have maintained a Class 2 ISO rating, and is grateful for the cooperation received from the Town of Normal Water Department and Metcom (McLean County Metro 9-1-1 Communications Center). As a result of the collaboration and inter-agency cooperation, we were able to maintain overall classification.
