Washington Retrospective Rating Enrollment Decisions are decisions made by the Washington State Department of Labor and Industries regarding the amount of premium each employer must pay for workers' compensation insurance. The decision is based on an employer's actual losses compared to the expected losses for their industry. Washington Retrospective Rating Enrollment Decisions can be made for two different types of employers: those in the Retrospective Rating Program and those in the Standard Premium Program. For employers in the Retrospective Rating Program, the Department of Labor and Industries will determine the amount of premium they must pay based on the employer's actual losses compared to the expected losses for their industry. The employer's premium rate is then adjusted at the end of the policy period based on the actual losses, which creates a "retrospective" approach to insurance premiums. For employers in the Standard Premium Program, the Department of Labor and Industries sets a fixed premium rate for workers' compensation insurance, regardless of the employer's actual losses. Both types of Washington Retrospective Rating Enrollment Decisions are made by the Department of Labor and Industries to ensure employers are paying a fair amount for workers' compensation insurance.
