• Provide clear, constructive feedback or corrections to help maintain overall data quality 

• Track recurring error patterns and report them to the project team 

• Ensure Trainer output meets the project's quality bar before final sign-off 

• Escalate unclear cases (e.g., illegible images, ambiguous questions) to the project team for resolution
