Quality Assurance Report
A reporter can run a quality assurance report that identifies possible data entry errors. We suggest reporters run a draft summary and a quality assurance report before submitting data. If the reporter submits the data and then finds an error, please call DNR to reset ARS. Learn more about quality assurance messages.
