Pursuant to a congressional request, GAO provided responses to a questionnaire sent to 54 federal agencies handling classified information to determine whether they implemented classified information nondisclosure agreements.

GAO provided: (1) actual figures, as well as estimates where actual data were not available, from the 48 agencies that responded to the questionnaire; (2) a list of federal agencies that responded to the questionnaire; and (3) detailed information on what federal agencies reported on their classified information nondisclosure agreement and prepublication review activities.
