How frequently should classified information be reviewed for declassification?

Classified information should be reviewed for declassification at least every five years as part of maintaining compliance with declassification policies. This requirement is established to ensure that information that no longer requires protection due to the passage of time or changes in circumstances is identified and made available to the public. Regular reviews help to uphold the principles of transparency and accountability while still protecting national security. By conducting these reviews at this interval, agencies can effectively manage their classified information systems, ensuring that only necessary information remains classified, preventing over-classification, and facilitating the proper declassification of outdated or unnecessary information. This process supports informed decision-making and provides an opportunity to reassess the sensitivity and relevance of the information classified.
