Security Clearances: Levels, Requirements, and How to Get Approved

Written by USFCR | Feb 21, 2025 1:00:00 PM

What Is a Security Clearance?

A security clearance is required for individuals working with classified information in federal agencies, defense contracting, or intelligence-related positions. Whether you're a government contractor, military personnel, or federal employee, holding a clearance confirms you can be trusted with sensitive data.

Clearances are granted after a comprehensive background investigation, including a criminal history review, financial background check, and foreign contact screening. Agencies such as the Defense Counterintelligence and Security Agency (DCSA) handle investigations to protect national security.

Failure to comply with clearance requirements can lead to revocation, job loss, fines, or even imprisonment. Understanding the clearance process—and how to maintain eligibility—can help you secure long-term federal contracting opportunities.

Types of Security Clearance

Confidential

The lowest level of clearance covers information that could cause damage to national security if disclosed.
Reinvestigation is required every 15 years.
Common for administrative and support roles.

Secret

Covers information that could cause serious damage if leaked.
Requires a deeper background check than Confidential.
Reinvestigation is required every 10 years.
Common among military personnel, intelligence officers, and defense contractors.

Top Secret (TS)

Grants access to data that could cause grave damage to national security.
Requires a comprehensive investigation and reinvestigation every five years.
Held by high-ranking government officials, intelligence professionals, and national security personnel.

Sensitive Compartmented Information (SCI) & Special Access Programs (SAP)

SCI: Grants access to intelligence-related data and may require polygraph testing.
SAP: Used for covert operations and classified defense projects.
Requires extra approvals, strict monitoring, and ongoing security training.

Mishandling SCI or SAP information can lead to criminal charges under the Espionage Act (18 U.S.C. § 793–798).

How to Get a Security Clearance

1. Find a Sponsoring Employer

Individuals cannot apply for clearance independently.
A federal agency or approved contractor must sponsor the application.
Sponsorship is based on job duties requiring classified access.

2. Undergo a Background Investigation
Conducted by the DCSA, this includes:

Criminal history review
Financial background check (credit score, bankruptcy, debt history)
Foreign contacts and travel history
Drug use history
Employment and education verification
Interviews with associates and former employers

Candidates with substantial debt, foreign ties, or past drug use may face delays or disqualification.

3. Clearance Adjudication & Approval

Officials review findings under 13 adjudicative guidelines, including loyalty, financial responsibility, and personal conduct.
If concerns arise, applicants may need to provide additional documentation.
Clearance is not guaranteed and can be denied or revoked based on investigative results.
Appeals are possible—candidates can present mitigating evidence to contest denials.

4. Maintaining Clearance Eligibility
Security clearance holders must follow strict reporting requirements, including:

Foreign travel and interactions with foreign nationals
Major financial changes (bankruptcy, large debts, unpaid taxes)
Legal issues that could impact trustworthiness

Continuous Evaluation (CE) allows agencies to monitor real-time security risks, ensuring immediate updates to clearance status.

Handling Classified Information: Your Responsibilities

A security clearance is a privilege, not a right. Mishandling classified documents can lead to criminal charges, job loss, and fines.

Common security violations include:

Discussing classified details in unsecured locations
Failing to store sensitive documents properly
Using personal devices for classified communication

With cybersecurity threats on the rise, clearance holders must follow IT security policies, including:

Using government-approved communication channels
Avoiding unsecured networks
Completing routine security training

Failure to comply with security protocols can result in suspension or revocation of clearance.

Security Clearance Transfers & Reciprocity

If you change jobs within the government or switch federal contractors, clearance reciprocity allows approved clearances to transfer without restarting the investigation.

However, different agencies may have additional screening requirements, which could cause delays.

Understanding reciprocity policies can help minimize processing times and job transition issues.
