Which statement best describes the purpose of documenting data sources for each domain rating?

• A. Transparency, auditability, resolving discrepancies, and validity.
• B. To keep data sources out of sight.
• C. To fulfill unrelated compliance.
• D. Documenting data sources supports transparency, auditability, resolving discrepancies, and validity.

Answer: (D)

Documenting data sources for each domain rating is about making the rating process transparent and traceable. When you record where the data came from, what data was used, and how it informed the domain rating, the trail from the rating back to its inputs is clear. This transparency lets others see exactly what supports the rating, which is essential for trust. It also makes the process auditable—an evaluator can follow the data back to its sources and verify calculations and methods. If discrepancies arise, having documented sources makes it possible to compare conflicting inputs and justify or correct the rating. Finally, the credibility or validity of the rating improves because you can assess whether the chosen data sources are appropriate, current, and reliable. In short, documenting data sources directly enables transparency, auditability, resolving discrepancies, and validity, which is why this statement best describes the purpose.
