Interim Clearance

Also known as: Interim Eligibility, Interim Security Clearance
Simply put

An interim clearance is a temporary grant of access to classified information that allows an individual to begin cleared work before their full background investigation is completed. It is issued after minimum investigative requirements are met and no adverse information is found in the initial review. It is not the same as a fully adjudicated, or final, clearance and generally remains in effect only until the investigation is completed and a final determination is made.

Formal definition

Interim clearance, also referred to as interim eligibility, is a temporary eligibility determination granted on the basis of completion of minimum investigative requirements and the absence of adverse information during the initial phase of a background investigation. According to the evidence, the interim eligibility determination is generally made concurrently with the initiation of the investigation and remains in effect until the investigation is completed and a final eligibility determination is made. Note that authority to grant interim eligibility rests with the responsible adjudicative or vetting authority, not with the employer; the evidence clarifies that interim clearance is not granted by the employer. Practitioners should treat interim eligibility as provisional and distinct from final adjudicated clearance status. This entry does not address specific investigative tiers, timelines, adjudicative criteria, or reciprocity rules, and readers should verify current requirements against the applicable governing authority (such as DCSA guidance).

Why it matters

Interim clearances serve a practical staffing function: they allow individuals to begin performing cleared work before a full background investigation is completed, provided minimum investigative requirements have been met and no adverse information surfaces during the initial review. For government contractors and program offices facing personnel demands, this mechanism can reduce the delay between hiring and productive cleared work. However, the interim status is provisional, and treating it as equivalent to a final adjudicated clearance is a common and consequential mistake.

A frequent point of confusion an expert would insist on correcting is the belief that an employer grants the interim clearance. The evidence is explicit that interim clearance is NOT granted by the employer; the authority to grant interim eligibility rests with the responsible adjudicative or vetting authority. Misattributing this authority can lead to compliance and access-control errors, including allowing access on the assumption that an internal approval suffices. Similarly, an interim eligibility determination should not be assumed to be permanent: it generally remains in effect only until the investigation is completed and a final determination is made.

Because an interim determination is based on an initial review rather than a completed investigation, it can be superseded by the final adjudication. Practitioners should treat interim eligibility as distinct from final clearance status and should not build long-term access assumptions around it. Specific investigative tiers, timelines, adjudicative criteria, and reciprocity rules are outside the scope of this entry, and readers should confirm current requirements against the applicable governing authority, such as DCSA guidance.

Who it's relevant to

Facility Security Officers and cleared contractors
FSOs and contractor personnel security staff rely on interim eligibility to onboard individuals into cleared roles before final adjudication, but they must recognize that the interim grant comes from the responsible vetting authority rather than the employer, and that it is temporary pending completion of the investigation.
Program managers and hiring officials
Program offices and hiring officials use interim eligibility to reduce delays in placing personnel on cleared work. They should plan for the possibility that a final adjudication may differ from the interim determination and should not treat interim status as a settled, permanent clearance.
Personnel security and adjudication practitioners
Adjudicative and vetting personnel make the interim eligibility determination based on completion of minimum investigative requirements and the absence of adverse information, and are responsible for the final eligibility determination that follows completion of the investigation.
Individuals awaiting a clearance determination
Applicants granted interim eligibility should understand that it is a temporary, provisional grant of access that is distinct from a final adjudicated clearance and remains subject to the outcome of the completed investigation. Individuals should verify the specifics of their status through the governing authority rather than assuming interim equals final.

Inside Interim Clearance

Interim Eligibility Determination
A temporary personnel security determination that allows an individual to access classified information before a final adjudication of their background investigation is complete, generally granted based on a favorable review of preliminary investigative steps.
Granting Authority
The designated authority responsible for making the interim determination, which within the defense context is typically the DoD Consolidated Adjudications Facility or another authorized adjudicative body; readers should verify the current responsible authority against applicable DoD policy.
Preliminary Screening Basis
The set of preliminary checks and forms, such as a completed security questionnaire and initial record checks, that generally must be favorably reviewed before an interim clearance can be granted.
Classification Level Scope
The level of classified access (for example, Confidential, Secret, or Top Secret) authorized under the interim determination, which may be limited relative to what the final clearance would permit.
Conditional and Time-Bound Nature
The interim status is provisional, remains in effect pending completion of the full investigation and final adjudication, and may be withdrawn if subsequent investigative results raise security concerns.

Common questions

Answers to the questions practitioners most commonly ask about Interim Clearance.

Does an interim clearance give me the same access as a final clearance?
No. An interim clearance is a temporary, provisional determination that generally permits access pending completion of the full investigation and adjudication. It is not equivalent to a final clearance and typically carries limitations on the scope of access. Interim access can be withdrawn if adverse information surfaces during the ongoing investigation. Confirm the specific access limitations against your facility security officer and current adjudicative guidance, as interpretations may vary by agency and by classification level.
Once I have an interim clearance, is my final clearance basically guaranteed?
No. Granting an interim clearance does not guarantee that a final clearance will be adjudicated favorably. The interim determination is made on preliminary information before the full investigation and adjudication are complete. Adverse information developed later in the process can result in denial or revocation. The interim and final determinations are separate decisions, and readers should verify the governing adjudicative process with the responsible authority rather than assume continuity.
Who has the authority to grant an interim clearance?
Interim clearance eligibility is generally granted by the designated adjudicative or security authority responsible for the individual, which may differ across agencies and between industry and government personnel. In the industrial security context, procedures are typically tied to processes described in the governing security policy framework. Because specific authorities and thresholds are subject to change and agency-specific interpretation, confirm the current process and the responsible official against official sources applicable to your program.
What conditions can cause an interim clearance to be withdrawn?
An interim clearance is provisional and may be withdrawn if information developed during the ongoing investigation or from other sources raises concerns under the applicable adjudicative guidelines. Because it precedes final adjudication, it is inherently more susceptible to withdrawal than a final determination. This entry does not cover the specific procedural steps, appeal rights, or timelines, which vary by agency; verify these against current authoritative guidance.
How should a security officer document and track individuals holding interim clearances?
As a general practice, security officers track interim-cleared individuals distinctly from fully cleared personnel so that access limitations and the pending status of the underlying investigation are visible and monitored. The precise recordkeeping systems and required data elements depend on the applicable program and agency policy. This entry does not prescribe a specific system or format; confirm requirements against the governing security policy and your organization's procedures.
Does an interim clearance affect what access controls must be applied to a person's activity?
In most implementations, an interim clearance is accompanied by access limitations that should be reflected in the physical and information system access controls applied to the individual. Because interim access is provisional, organizations generally maintain the ability to restrict or remove access promptly if the status changes. The specific controls, their tailoring, and any system-level enforcement are implementation details that should be verified against current authoritative guidance and program policy.

Common misconceptions

An interim clearance is the same as a final clearance and carries the same standing.
An interim clearance is a provisional determination based on preliminary review, not a completed adjudication. It remains subject to withdrawal and is superseded once the full investigation is finalized and a final eligibility determination is made.
Once granted, an interim clearance stays in effect indefinitely.
An interim clearance is time-bound and conditional, existing only pending completion of the underlying investigation and final adjudication. It can be revoked if new information develops, and readers should confirm current duration and revocation rules against applicable DoD guidance.
Holding a personnel clearance, including an interim one, means an individual is automatically authorized to access any classified system or information.
A clearance addresses eligibility for access, but actual access also requires a validated need-to-know and, for information systems, appropriate system authorization. Personnel eligibility and system authorization are distinct and should not be conflated.

Best practices

Treat interim clearances as provisional and track them separately from final determinations, documenting the pending investigation status and any access limitations tied to the interim grant.
Verify the current granting authority, eligibility criteria, and permissible access levels against applicable DoD personnel security policy before relying on an interim determination, since these can change across revisions.
Enforce need-to-know in addition to the clearance itself, ensuring interim-cleared personnel receive only the access their role requires.
Establish a monitoring process so that interim clearances are promptly reviewed, reissued, or withdrawn when final adjudication concludes or when adverse information emerges.
Maintain audit-ready records of the preliminary screening basis and interim decisions to support later assessment and continuous evaluation activities.
Confirm any contractual or agency-specific interpretation with current authoritative sources, since interim clearance handling may differ across DoD components and does not by itself address system authorization requirements.
