This presentation outlines the function and importance of the FamilySearch Data Quality Score, an automated diagnostic tool designed to evaluate the logical consistency and structural soundness of profiles within the collaborative family tree. By addressing formatting issues, explicitly tagging source records, and reconciling duplicate entries, users can methodically improve profiles from a low or medium score to a high rating. Ultimately, maintaining a high data quality score creates a protective layer of verifiable evidence that safeguards genealogical research against future careless edits or incorrect merges.
