The Wisconsin Compensation Rating Bureau (WCRB) is a licensed rate service organization created by Wisconsin statute. We are responsible for the classification of employers, the rates and rating plans used, all policy forms and endorsements, and the collection and analysis of all statistical and other data needed to meet our responsibilities which includes the calculation and distribution of experience modifiers. The WCRB also administers the Wisconsin Worker's Compensation Insurance Pool. While not a state agency, WCRB is regulated by the State of Wisconsin Office of the Commissioner of Insurance (OCI) and works very closely with the Worker's Compensation Division of the Wisconsin Department of Workforce Development (DWD). WCRB assists DWD in its enforcement activities. By law, the WCRB receives required information on every worker's compensation policy issued to every employer with operations in Wisconsin and every termination thereof, and electronically transmits this information to the Worker's Compensation Division. The WCRB is an unincorporated association of insurers who, by law, must be members of the WCRB. Management Committees WCRB By-Laws
