DATA Act: Quality of Data Submissions Has Improved but Further Action is Needed to Disclose Known Data Limitations, Report to Congressional Addressees [open pdf - 5MB]
From What GAO [Government Accountability Office] Found: "The Digital Accountability and Transparency Act of 2014 (DATA Act) requires federal agencies to report spending data to USAspending.gov, a public-facing website. A total of 96 federal agencies submitted required spending data for quarter four of fiscal year 2018 (Q4 FY2018). GAO examined the quality of these data and compared the results with the results of its prior review of quarter two of fiscal year 2017 (Q2 FY2017) data, as appropriate. GAO identified improvements in overall data quality, but challenges remain for completeness, accuracy, use of data standards, disclosure of data limitations, and overall data governance."
