Confidential Clearance
Confidential is the lowest level of security clearance granted by the U.S. government for access to classified national security information.
Quick Facts
| Level | Lowest standard clearance |
| Damage if disclosed | Damage to national security |
| Investigation | Tier 1 or Tier 3 (National Agency Check) |
| Reinvestigation | Every 15 years |
| Typical timeline | 1-3 months |
What It Means
A Confidential clearance allows access to information that, if disclosed without authorization, could reasonably be expected to cause damage to national security[1]. This is distinct from Secret (serious damage) and Top Secret (exceptionally grave damage).
Investigation Requirements
Confidential clearances typically require a Tier 1 or Tier 3 background investigation, depending on the position. The investigation includes:
- National agency database checks
- Credit history review
- Criminal records check
- Verification of citizenship and identity
The process is less extensive than investigations for higher clearance levels[2].
Common Positions
Confidential clearances are often required for:
- Entry-level military personnel
- Some administrative government positions
- Contractors with limited access to classified materials
- Support staff at cleared facilities
Upgrade Path
Many positions that start with Confidential access may later require a Secret or Top Secret clearance. If you already hold a Confidential clearance, upgrading typically requires a new investigation appropriate to the higher level.
