How often should classified information be reviewed for potential declassification?

The frequency of reviewing classified information for potential declassification is governed by specific guidelines which suggest that such reviews should occur every five years or as determined by the classification authority. This allows for a systematic evaluation of classified materials to ensure that information is only kept classified as long as necessary.

The rationale behind this five-year cycle is rooted in the understanding that the sensitivity of information can change over time. Factors such as the passage of time, changes in national security interests, or developments in related fields can all affect whether certain classified information still warrants protection. By reviewing classified data periodically, agencies can lighten their burden of classification and promote transparency whenever possible.

While an annual review might seem thorough, it could lead to inefficiencies and unnecessary strain on resources. Conversely, a ten-year review would be too infrequent and potentially allow sensitive information to remain classified longer than necessary. Finally, only reviewing classified information upon request from external authorities would not establish a proactive approach to evaluating declassification, thereby missing opportunities for timely reassessment.
