Personnel Security Clearance

A Personnel Security Clearance (PCL) is the government's formal determination that a specific individual is trustworthy and eligible to access classified national security information up to a designated level. PCLs are not issued to companies; they attach to individual employees and follow those employees across employment, subject to continuous eligibility and proper transfer procedures. Without cleared personnel, a contractor cannot perform work on classified contracts regardless of the company's own facility authorization.

What is Personnel Security Clearance?

PCLs are governed by Executive Order 12968 (Access to Classified Information) and adjudicated under the 13 Adjudicative Guidelines established in Security Executive Agent Directive 4 (SEAD 4). The Defense Counterintelligence and Security Agency (DCSA) conducts background investigations and adjudications for most DoD and many non-DoD contractors; certain intelligence community agencies sponsor and adjudicate their own clearances.

The three primary clearance levels are Confidential, Secret, and Top Secret. Above those levels, access to Sensitive Compartmented Information (SCI) and Special Access Programs (SAPs) requires additional eligibility determinations beyond the base clearance level.

A contractor employee cannot self-sponsor a clearance. The employer's Facility Security Officer (FSO) must submit the request through the Defense Information System for Security (DISS), the system that replaced the Joint Personnel Adjudication System (JPAS). The investigation scope scales with the clearance level: a Confidential or Secret clearance requires a Tier 3 investigation covering the prior seven years, while a Top Secret clearance requires a Tier 5 investigation covering the prior ten years. Investigations are conducted by DCSA's background investigation service.

Clearances are not automatically transferable between employers, but an individual who changes employers can have an existing clearance transferred to the new facility if it remains in scope and the individual has maintained continuous eligibility. The new FSO initiates the transfer through DISS.

Why it matters for contractors

Cleared work requires time and planning that uncleared work does not. The background investigation process for a new Secret clearance typically takes several months; Top Secret clearances can take six months to a year or longer depending on investigation complexity and agency workload. Contractors who win classified contracts must have cleared personnel in place or accept that key personnel will not have access to classified performance work statements, systems, or facilities until investigations complete.

This timeline affects proposal strategy. Contractors should identify cleared incumbents among their staff or potential hires during the bidding phase and disclose clearance status in key personnel sections. Proposal evaluators routinely view uncleared key personnel as program risk, particularly for contracts that begin performance immediately after award.

Maintaining clearances also requires continuous reporting obligations. FSOs must report adverse information, foreign contacts, foreign travel, and other reportable events on cleared employees. Failure to report is itself an adjudicative concern that can result in clearance suspension or revocation.

Example

A defense contractor wins a Secret-level software development contract for the Army. Before employees can access classified systems or receive the classified performance work statement, the company's FSO submits clearance requests for each assigned employee through DISS. Employees who already hold active Secret clearances are added to the contract's access roster and can begin classified work promptly. New hires without existing clearances must complete a Tier 3 background investigation before receiving access, which delays their productive start on the classified portions of the contract by several months.
