ISO Ratings
Your ISO score, explained, and improved.
An ISO score (Public Protection Classification) is a 1-to-10 rating of how well a fire department can protect its community, Class 1 is best, and it directly influences what residents and businesses pay for property insurance. The rating weighs your department (50%), water supply (40%), emergency communications (10%), and community risk reduction (up to 5.5 bonus points). This series covers how the score works, what evaluators look for, and how departments use documentation to defend every point.
Why does an ISO score matter to your community?
Insurers use your Public Protection Classification to set property premiums: a better class means measurably lower insurance costs for the homes and businesses you protect. Inside the department, the rating doubles as a benchmark: state and federal entities may weigh it in funding decisions, and a documented improvement plan is budget-request ammunition. The common thread across every ISO point category is proof: training hours logged, hydrants flow-tested, apparatus maintained, all of it documented in a form an evaluator can verify.

Common questions
What is a good ISO score for a fire department?
Lower is better: Class 1 is the best rating and Class 10 means the area doesn't meet minimum criteria. The national average is roughly Class 5.5, so anything at Class 4 or better puts a department ahead of most peers, and each class improvement can translate to insurance savings for the community.
How does a fire department improve its ISO score?
Target the categories with the most available points: department operations (50%: staffing, apparatus, training hours), water supply (40%: hydrant testing and records), communications (10%), and community risk reduction (up to 5.5 bonus points). Because evaluators only credit what's documented, complete training logs, truck checks, and hydrant records are often the fastest points a department can reclaim.
How does RedAlert help with ISO evaluations?
RedAlert keeps the records ISO evaluators ask for (training hours by member, apparatus maintenance, hydrant testing, incident history) in one system with custom reporting that produces evaluation-ready documentation instead of a pre-visit scramble.
