Ratio studies are often used for oversight purposes, but they can also be used for internal ________ in an effective assessment system.

• A. quality control
• B. process improvement
• C. data validation
• D. compliance monitoring

Answer: (A)

Ratio studies compare assessed values to market values to gauge valuation accuracy across property types and areas. While they’re often used to satisfy oversight, they also provide internal quality control by highlighting where valuations are consistently off, where biases exist, or where the model and procedures aren’t performing as intended. This makes it possible to calibrate methods, target training, and adjust processes so the system maintains accurate and consistent valuations over time. Data validation, compliance monitoring, and broader process improvements are related ideas, but the core internal function tied to ratio studies is quality control—ensuring the valuation process produces reliable results.
