The general rules and basic procedures for classifying a business are contained in Part 3 of the California Workers' Compensation Uniform Statistical Reporting Plan—1995 (Uniform Statistical Reporting Plan). The Uniform Statistical Reporting Plan is part of the California Code of Regulations and is approved by the Insurance Commissioner. In summary, any business specifically described by a classification must be assigned to that classification. Any business not specifically described by a classification must be assigned to the most analogous (most similar) classification. Classifications assigned to a business are used by its insurer to submit payroll and loss data to the WCIRB. The WCIRB, in turn, uses this data by classification for experience rating purposes and development of pure premium rates.
