Which Part explains that premium is determined using classification codes contained in the insurer's manuals, with the Scopes Manual being commonly used for class codes?

• A. Part Five
• B. Part Four
• C. Part One
• D. Part Six

Answer: (A)

This item tests where premium determination is explained, specifically that premium is set by applying rates tied to classification codes found in the insurer’s manuals, with the Scopes Manual commonly used to define those class codes. In workers’ compensation practice, codes categorize the insured’s operations and exposures, and each code has an associated rate. The premium is calculated by applying the appropriate rate to the insured’s exposure base (often payroll), adjusted for any modifiers or endorsements. The Scopes Manual provides the standard definitions used to classify different lines of work, helping ensure consistent coding across insurers and states. Part Five is the section that lays out how rating and premium are determined, including the use of those classification codes from the insurer’s manuals. The other parts cover different policy aspects like coverage provisions, duties, or claims handling, not how premium is computed.
