On a U.S. job application, “security clearance” usually means the position may require a government determination that you are eligible to access classified national security information or perform designated national security-sensitive duties. The employer—not the applicant—decides whether the role needs clearance processing and initiates it. Having eligibility does not guarantee a job or give you unrestricted access to information.
What a security clearance means
The Defense Counterintelligence and Security Agency (DCSA) defines a security clearance as a personnel-vetting determination that a person is eligible for access to national security information and/or assignment to duties designated as national security-sensitive. It is tied to the position and its requirements, not something an individual obtains independently. DCSA’s adjudications FAQ explains the job-based nature of the requirement.
A clearance is an eligibility decision, not a certificate you can buy or apply for on your own. The organization determines whether the role requires processing and initiates the request. DCSA describes the contractor applicant process on its Processing Applicants page.
Eligibility is not the same as access
Even when a person is eligible at a particular level, that alone does not authorize access to every classified record at that level. Access also requires authorization for the specific information and a need to know it for assigned duties. Some information has additional controls, including Sensitive Compartmented Information (SCI) and Special Access Programs (SAP), which may require special approval. SCI and SAP are not simply additional levels above Top Secret. DCSA’s Facility Security Officer FAQ describes the principal levels and additional access restrictions.

What the job listing’s wording may mean
Employers use phrases such as “clearance required,” “active clearance,” “eligible,” and “sponsorship available” differently. The wording alone may not tell you whether you must already have eligibility before starting, whether the employer will sponsor processing, or which level and special access the position needs. Ask the recruiter or security contact directly:
- What clearance level and any additional access are required?
- Must I already be eligible before I start, or will the employer initiate processing?
- Does the employer sponsor candidates for this specific role?
- At what point in the hiring process must eligibility be in place?
A clearance requirement is not a promise of employment. DCSA says hiring selection is separate from clearance processing. For contractors, its FAQ describes a specific circumstance in which processing may begin before the start date: after the candidate accepts a written employment commitment specifying commencement within 30 days of eligibility. That contractor guidance should not be assumed to apply to every employer or government agency. See DCSA’s Facility Security Officer FAQ.
The three main clearance levels
DCSA identifies Confidential, Secret, and Top Secret as the three principal levels. The level reflects the potential damage to national security that unauthorized disclosure could cause; the duties of a particular job determine which level is needed. Top Secret is the highest of these three, but it does not by itself grant access to every kind of classified information.
| Level | What it indicates | What it does not mean |
|---|---|---|
| Confidential | Eligibility for access at the Confidential level, if the job requires it and access is authorized. | It does not provide blanket access to all Confidential information. |
| Secret | Eligibility for access at the Secret level, if the job requires it and access is authorized. | It does not provide blanket access to all Secret information. |
| Top Secret | Eligibility for access at the highest of the three principal levels, if the job requires it and access is authorized. | It does not automatically include SCI, SAP, or access to all Top Secret information. |
For each level, access remains limited by authorization and need to know. Specially protected information may have additional approval requirements. DCSA’s FAQ provides its overview of levels and additional access controls.

What happens after the employer initiates processing
For contractor applicants, DCSA describes an employer determination of need, an electronic application and fingerprints for initial requests, agency review, and investigation processing. The exact process depends on the case and organization. Completing an investigation is not itself a clearance grant; an adjudicator must make an eligibility decision.
Investigation and adjudication are different steps
The investigation gathers information relevant to the decision. Adjudicators consider the applicant’s information, investigative findings, and other reliable information under national security adjudicative guidelines, weighing favorable and unfavorable information. DCSA outlines this distinction in its adjudications FAQ.

Interim eligibility is possible, not guaranteed
In some cases, interim eligibility may be considered while the investigation is underway. DCSA says it is issued only when the facts and circumstances support access as consistent with national security interests, and it generally lasts until the investigation is complete and a final determination is made. An applicant should not assume an interim decision will be granted or rely on a standard processing timeline. Details are on DCSA’s Interim Clearances page.

“Background check” and “security clearance” are related but not interchangeable. A background investigation may support a clearance decision, but investigations can also be required for suitability even when a job does not involve classified access. Depending on the position, an agency may consider suitability, fitness, or security eligibility. DCSA describes these distinctions in its Investigations & Clearance Process overview.
