An active security clearance means two things are true at the same time: the federal government has found you eligible to access classified national security information, and you currently occupy a position that requires that access. Eligibility alone is not enough. The “active” label depends on the need-to-know piece, which is tied to your job. Take away the position, and the eligibility can survive for a while, but the clearance stops being active in the sense that matters day to day.
Active, Current, and Inactive
Federal law defines an access determination as a two-part finding: that you are eligible for classified information and that you have a current need to know it in your role.1Office of the Law Revision Counsel. 50 USC 3341 – Security Clearances An active clearance satisfies both parts. You have been investigated, adjudicated favorably, and placed in a position where access to classified material is necessary.
When you leave a cleared position, your eligibility does not expire immediately. It typically remains “current” for up to two years, which means another agency or cleared contractor can bring you on without restarting the investigation.2United States Department of State. Security Clearances – FAQ Updates During that window, the clearance is often called “inactive” or “current but not active.” You cannot see classified material during that stretch because the need-to-know piece is gone. If two years pass without you entering a new cleared position, the eligibility lapses and a fresh investigation is required.
Clearance Levels and Add-On Access
Three classification levels sit under an active clearance, each tied to how much harm a leak could cause. Confidential covers information whose unauthorized release could damage national security. Secret applies when the damage would be serious. Top Secret is reserved for information whose disclosure could cause exceptionally grave damage.3The White House. Executive Order 13526 – Classified National Security Information Your level sets the ceiling of what you can see, and even then you only get material relevant to your duties.
Two additional access categories sit on top. Sensitive Compartmented Information, or SCI, controls access to intelligence from particularly sensitive sources or methods and requires a Top Secret clearance as a baseline plus a separate approval. Special Access Programs, or SAPs, narrow access further to a small, specifically approved group. You can hold a Top Secret clearance and still be locked out of an SAP unless you have been individually read into that program.
Public Trust Positions Are Different
A public trust position requires a background investigation, but that investigation uses the SF-85P rather than the SF-86 and evaluates suitability for a federal role rather than eligibility for classified information.4National Institutes of Health Office of Management. Understanding U.S. Government Background Investigations and Reinvestigations It does not grant access to classified material. If a role mentions a public trust determination, it is not a security clearance.
Keeping an Active Clearance Active
Holding a clearance is not a one-time event. The government watches cleared people continuously to make sure they still meet the standards.
Continuous Vetting
The old model required a full reinvestigation every five years for Top Secret holders and every ten years for Secret holders. Under the Trusted Workforce 2.0 initiative, the entire national security workforce was transitioned to continuous vetting by the end of 2022.5Performance.gov. Trusted Workforce 2.0 Transition Report Continuous vetting runs automated checks against financial records, criminal databases, and other government records on an ongoing basis rather than waiting for a scheduled reinvestigation. Enrollment now satisfies what used to be the periodic reinvestigation requirement.
The change matters for you as a holder. Potentially adverse information is flagged an average of three years sooner for Top Secret holders and seven years sooner for Secret holders compared to the old system.5Performance.gov. Trusted Workforce 2.0 Transition Report Assume relevant records are being checked regularly.
Reporting Obligations
Clearance holders must self-report certain life changes to their security office. These include foreign travel, new or deepened relationships with foreign nationals, significant financial problems like large debts or bankruptcy filings, arrests or criminal charges, and changes in marital status. Most cleared facilities and agencies have specific reporting forms and timelines. Failing to report something that later surfaces through continuous vetting looks far worse than proactively disclosing it.
What Can Cost You Your Clearance
Adjudicators evaluate eligibility against guidelines covering thirteen broad areas of concern, laid out in Security Executive Agent Directive 4.6Defense Counterintelligence and Security Agency. SEAD 4 Adjudicative Guidelines The categories most likely to surface for someone already cleared include:
- Financial problems: unmanaged debt, failure to file taxes, and spending beyond your means. No specific dollar threshold triggers a denial, but adjudicators look at whether debts are under control and whether behavior suggests poor judgment or vulnerability to coercion. Financial issues are widely regarded as the single most common reason clearances are denied or revoked.
- Foreign contacts and influence: close relationships with foreign nationals, especially those connected to foreign governments, raise questions about divided loyalties or susceptibility to pressure.
- Foreign preference: exercising rights of dual citizenship or using a foreign passport can raise concerns, though these can be mitigated by circumstances like citizenship acquired through birth rather than by choice.7eCFR. 32 CFR Part 147 – Adjudicative Guidelines for Determining Eligibility for Access to Classified Information
- Drug involvement: past drug use is evaluated on recency, frequency, and evidence of changed behavior. Current illegal drug use is disqualifying.
- Criminal conduct: arrests, charges, and convictions are all relevant, with seriousness and recency carrying the most weight.
- Personal conduct: dishonesty during the investigation process, patterns of rule-breaking, or conduct showing questionable judgment.
Other guideline categories cover alcohol consumption, psychological conditions, mishandling of classified information, misuse of information technology, and allegiance to the United States, among others. Adjudicators use a “whole person” analysis: the nature and seriousness of the concern, how long ago it occurred, what you were doing at the time, whether you have taken steps to address it, and how likely it is to recur. A 22-year-old’s marijuana use five years ago lands very differently than a 40-year-old’s ongoing prescription fraud.
Moving Between Agencies
Federal policy requires agencies to accept another agency’s clearance determination rather than start over. This is called reciprocity, and it is governed by Security Executive Agent Directive 7.8National Counterintelligence and Security Center. SEAD 7 – Reciprocity of Background Investigations and National Security Adjudicative Determinations If you hold an active clearance at one agency and move to a position at another agency at the same or lower clearance level, the new agency is generally required to accept your existing clearance without demanding a new SF-86 or fresh investigative checks.
For interagency visits, coordination, or information exchange, the rules are stricter. The receiving agency must accept your active clearance regardless of how old the underlying investigation is and cannot request updated security paperwork just for those purposes.8National Counterintelligence and Security Center. SEAD 7 – Reciprocity of Background Investigations and National Security Adjudicative Determinations
Reciprocity has limits. Agencies can refuse to accept your clearance if new derogatory information has surfaced since your last investigation, if the underlying investigation is more than seven years old, if your clearance was granted on an interim or temporary basis, or if your eligibility is currently suspended or revoked. Reciprocity usually works, but some agencies have historically been slow to honor it. If you meet pushback, the directive gives you ground to stand on.
Leaving a Cleared Position
When employment in a cleared position ends, whether you resign, retire, or transfer to an uncleared role, you go through a security debriefing. In that debriefing you acknowledge that you have returned all classified materials, that you will not disclose classified information you learned on the job, and that you will report any attempts by others to solicit that information from you.9Center for Development of Security Excellence. Termination Briefing Short The debriefing also reminds you that anything you plan to publish, including books, articles, and speeches, must be submitted for pre-publication review. These obligations survive employment indefinitely, and the criminal penalties for unauthorized disclosure remain in force for the rest of your life.
After debriefing, your eligibility typically stays current for up to two years.2United States Department of State. Security Clearances – FAQ Updates During that window a new employer can pick up your eligibility and activate it without a new investigation, assuming nothing disqualifying has emerged. If you may return to cleared work, that clock matters. Once it runs out, the whole process starts over, and given typical investigation times, the gap can be long and painful.
If Your Clearance Is Denied or Revoked
When the adjudicating agency reaches a preliminary decision against granting or continuing your clearance, it issues a Statement of Reasons, or SOR. The SOR spells out which adjudicative guidelines you triggered and the specific facts behind the unfavorable decision. It works as both a charge sheet and a roadmap for your response.
For defense contractor personnel, the appeal goes through the Defense Office of Hearings and Appeals. You can respond in writing to the SOR and request a hearing before an administrative judge. If neither side requests a hearing, the judge decides on the written record alone. A loss can be appealed to the DOHA Appeal Board within 15 days. The Appeal Board reviews the judge’s decision for legal errors and does not accept new evidence, so anything you want considered needs to be in the record at the hearing stage.10Defense Office of Hearings and Appeals. Overview of DOHA’s Industrial Security Mission
Federal employees face a different process depending on their agency, and some agencies provide fewer procedural protections than DOHA. Whatever the process, the responses that work best address each listed concern directly with documentary evidence showing the problem has been mitigated. The appeal window is short and unforgiving toward vague responses and missed deadlines.
