Managing Sensitive Information: Actions Needed to Ensure Recent Changes in DOE Oversight Do Not Weaken an Effective Classification System, Report to the Chairman, Subcommittee on National Security, Emerging Threats and International Relations, Committee on Government Reform, House of Representatives [open pdf - 685KB]
"DOE's Office of Classification's systematic training, comprehensive guidance, and rigorous oversight programs had a largely successful history of ensuring that information was classified and declassified according to established criteria. However, an October 2005 shift in responsibility for classification oversight to the Office of Security Evaluations has created uncertainty about whether a high level of performance in oversight will be sustained. […]GAO was asked to assess the extent to which (1) DOE's training, guidance, and oversight ensure that information is classified and declassified according to established criteria and (2) DOE has found documents to be misclassified."
