Wisconsin Workers Compensation Class Codes

Wisconsin Workers Compensation Classification CodesLooking for a list of Wisconsin workers compensation class codes? Wisconsin is not under the jurisdiction of the NCCI classification system.

If you have a classification question or believe you have been incorrectly classified, please see The Employer’s Workers Compensation Classification Guide.

As an “independent” WC state, the Wisconsin Rating Bureau (WCRB) determines classification codes, premiums, experience modifiers, and workers comp rates.

NCCI (National Council on Compensation Insurance) does collect policy data for the purpose of calculating experience modifiers for employers doing business in other states.

About the Wisconsin Rating Bureau (WCRB)

  • WCRB is an unincorporated & independent rate service association created by Wisconsin statute.
  • WCRB is responsible for the classification, rates and rating plans used by all employers in the state of Wisconsin.
  • WCRB regulates workers compensation policy forms and endorsements, as well as the collection and analysis of all statistical data necessary for calculating and distributing experience modifiers for local state businesses.
  • The Wisconsin Rating Bureau also manages the Wisconsin Worker’s Compensation Insurance Pool.
  • While the WCRB is not a state agency, they are regulated by the State of Wisconsin Office of the Commissioner of Insurance (OCI). The Wisconsin Rating Bureau also 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.
