This Data Quality Assessment (DQA) Checklist is provided as a recommended tool that an operating unit (OU) may use to complete its DQAs. If the OU prefers or has successfully used a different tool for conducting and documenting its DQAs in the past, they are free to continue the use of that tool instead. The checklist below is intended to assist in assessing each of the five aspects of data quality and provide a convenient manner in which to document the OU’s DQA findings.
