In the report released Thursday, the inspector general concludes that the cemetery has been transformed into a premier institution. The report in particular cites the implementation of geospatial technology to track cemetery operations.
It also cites progress in an ongoing effort to verify the names and dates on all of the headstones and grave markers at Arlington. More than 400,000 people are buried there.
Congress mandated the inspector general audits in 2010 after reports of misplaced remains.
Sen. Claire McCaskill, a Missouri Democrat who has held oversight hearings on the issue, said she is pleased by the turnaround.
