## Definition

not having a secret level or a specific category. You use this to describe information that is safe for everyone to see or things that have not been sorted into a group.

For teachers: not assigned to a specific security level or category; not restricted by confidentiality rules. Often used in administrative or governmental contexts to indicate that data is publicly accessible.

## Examples

- The report contains only unclassified information.
- After the investigation was completed, the government released the unclassified version of the report to the public.
- While the core data remains under strict security, the unclassified summary provides enough detail for researchers to understand the general findings without compromising national interests.
