The Insurance Services Office (ISO) is best described as which of the following?

• A. A government regulator
• B. A consumer protection agency
• C. An insurance advisory organization
• D. A direct writing insurer

Answer: (C)

ISO is best described as an insurance advisory organization. It serves the industry by developing standardized policy forms, rating and underwriting guidelines, and providing statistical data and risk-management information that insurers use to price, underwrite, and administer claims. This role helps create consistency across policies and simplifies comparisons for insureds, while giving insurers a reliable source of data and forms.

It’s not a government regulator, since state departments of insurance handle regulatory duties. It’s not a consumer protection agency, because its purpose is to support insurers rather than advocate for consumers. And it’s not a direct writing insurer, since it does not issue or sell policies to the public.
