An active security clearance means you currently hold government-verified eligibility to access classified information and you are working in a position that requires that access. Two things have to be true at once: the government’s favorable trustworthiness determination on you is in force, and your employer has formally established a need for you to handle classified material. Drop either half and your status changes. Leave the cleared job and your clearance becomes “current” rather than active. Let the eligibility itself lapse and you have nothing to reactivate.
That distinction, drawn sharply by the Defense Counterintelligence and Security Agency (DCSA), governs almost every practical question people ask about their clearance: whether they can start a new cleared job quickly, whether their old investigation still counts, what they have to report while they hold access, and what they owe the government after they walk away.
Active, Current, and Expired
An active clearance lets you walk into a classified space and do your job. Your background investigation is up to date, the adjudication is favorable, and your employer has verified the need-to-know.
A current clearance means you passed the investigation and the government still considers you trustworthy, but you are not sitting in a position that uses that access. The trustworthiness determination is on the books; it just is not being exercised. Uniform standards for making those determinations come from Security Executive Agent Directive 4, which sets one set of adjudicative criteria across every department and agency.1Office of the Director of National Intelligence. Security Executive Agent Directive 4 – National Security Adjudicative Guidelines
An expired clearance is one that has aged out of the current window with no cleared employment to keep it alive. At that point you are starting over with a new investigation if you want back in.
The Level Your Active Clearance Sits At
Every active clearance is pegged to one of three levels, and the level determines what classified information the access actually covers:
- Confidential covers information whose unauthorized release could cause damage to national security. The background check looks back seven years and is largely administrative.
- Secret covers information whose release could cause serious damage. Most Secret investigations rely heavily on automated records checks.
- Top Secret covers information whose release could cause exceptionally grave damage. It requires a Single Scope Background Investigation with interviews of references, neighbors, and coworkers.
Sensitive Compartmented Information (SCI) and Special Access Programs (SAPs) are not separate levels. They are additional access gates layered on top of Top Secret, each with its own adjudication and often its own database.
What Keeps a Clearance Active Day to Day
Holding an active clearance is not a one-time event. The government expects you to self-report life changes that could affect your trustworthiness, and it is running automated checks on you in the background.
Self-Reporting Under SEAD 3
Security Executive Agent Directive 3 spells out what cleared personnel have to report and when.2Office of the Director of National Intelligence. Security Executive Agent Directive 3 – Reporting Requirements for Personnel with Access to Classified Information or Who Hold a Sensitive Position You must tell your security office about:
- Foreign travel, contacts, financial interests, or employment
- Changes in marital status, cohabitation, or name
- Criminal activity or arrests
- Significant financial changes
- Treatment for substance abuse or certain psychological conditions
- Known or suspected unauthorized disclosures of classified information
Reports go through your Facility Security Officer (FSO) or cognizant security office. DCSA publishes a desktop aid summarizing the categories and deadlines.3Defense Counterintelligence and Security Agency. SEAD 3 Reporting Desktop Aid for Cleared Industry The failure to report is itself a security concern. People lose active clearances not because they had a financial problem or a foreign contact, but because they hid it.
Continuous Vetting Under Trusted Workforce 2.0
The old model of a Secret investigation every ten years and a Top Secret investigation every five is being retired. The Trusted Workforce 2.0 initiative is replacing periodic reinvestigations with Continuous Vetting (CV), which runs automated checks against government and commercial data on an ongoing basis.4Center for Development of Security Excellence. Continuous Vetting Methodology This is a shift from the earlier Continuous Evaluation program under SEAD 6, which supplemented periodic reviews rather than replacing them.5Office of the Director of National Intelligence. Security Executive Agent Directive 6 – Continuous Evaluation
CV scans seven categories of automated data: eligibility records, terrorism databases, criminal activity, suspicious financial activity, public records, credit bureau data, and foreign travel records. When an alert comes in, DCSA decides whether it warrants further investigation and adjudication.
Agencies were required to enroll their full non-sensitive public trust populations into continuous vetting by September 30, 2025, and are now working toward complete enrollment of sensitive and national security populations.6Office of Personnel Management. Streamlining Vetting Processes in Support of the Merit Hiring Plan Traditional periodic reinvestigation cycles are being eliminated in favor of this near-real-time approach.
What Can Cost You an Active Clearance
SEAD 4 identifies 13 categories of concern that adjudicators weigh when deciding whether to grant, continue, or revoke a clearance:1Office of the Director of National Intelligence. Security Executive Agent Directive 4 – National Security Adjudicative Guidelines
- Allegiance to the United States
- Foreign Influence
- Foreign Preference
- Sexual Behavior
- Personal Conduct
- Financial Considerations
- Alcohol Consumption
- Drug Involvement and Substance Misuse
- Psychological Conditions
- Criminal Conduct
- Handling Protected Information
- Outside Activities
- Use of Information Technology Systems
Financial problems and personal conduct do most of the work in clearance denials and revocations. Unresolved debt, bankruptcies, tax issues, and unexplained wealth raise flags under Guideline F. Dishonesty on the SF-86 triggers Guideline E concerns that are among the hardest to mitigate, because they go directly to trustworthiness. Drug use, particularly recent use or use while holding a clearance, is treated seriously under Guideline H.
None of these is an automatic disqualifier. Adjudicators apply a “whole person” analysis, weighing the seriousness of the concern against evidence of rehabilitation, the passage of time, and the surrounding circumstances. A DUI from a decade ago that you disclosed honestly is far less damaging than a DUI from last year that you tried to conceal.
What Happens When You Leave a Cleared Job
The most common way an active clearance stops being active is that you leave the position. Your employer removes the access authorization, and your status shifts from active to current. As part of the transition you go through a security debriefing acknowledging that your obligation to protect classified information continues after you walk out the door.
The Standard Form 312, the nondisclosure agreement you signed when you were first granted access, makes clear that all conditions and obligations apply at all times, including after separation, unless you are released in writing by an authorized government representative.7General Services Administration. Standard Form 312 – Classified Information Nondisclosure Agreement You return all classified materials, and you agree to promptly report any unauthorized attempts to solicit classified information from you.
The 24-Month Window
Once you leave, eligibility doesn’t vanish overnight. A clearance generally remains current for up to 24 months after you separate from a cleared role. Resume cleared work inside that window and a new employer can typically reactivate your access without a new investigation. Go beyond 24 months without cleared employment and you need a fresh background investigation to get back in.8U.S. Army. Army Security Clearance Fact Sheet
Even inside the window, the underlying investigation carries its own shelf life that affects whether a new agency has to accept your prior work or can require something new.
Loss of Jurisdiction
A trickier situation arises when you leave a cleared position while an investigation or adjudication is still open. This creates a “loss of jurisdiction,” meaning the adjudicating agency no longer has authority to complete or decide your case. It is an administrative pause, not a denial or revocation, and it does not mean you failed. It does mean your clearance is frozen. You cannot access classified information until a new sponsor picks up the case, jurisdiction is restored, and any outstanding issues are resolved.
If you are considering leaving and you know you have an open investigation or an unresolved security concern, talk to your FSO first. Separating before the process concludes can create complications that take far longer to untangle than simply seeing the adjudication through.
Getting an Active Clearance Back
Reinstating from current to active is usually straightforward when the investigation is still valid. Your new employer submits an access request, and the adjudicating authority confirms no new disqualifying information has appeared. If your file carries a flag from a prior employer, such as an incident report filed at separation, your new employer will need to work with you to address it before access is restored.
Reciprocity Between Agencies
Federal policy requires agencies to accept each other’s clearance determinations rather than running duplicate investigations. Executive Order 13467 established that background investigations and adjudications must be mutually and reciprocally accepted, and that no agency may impose additional investigative requirements without approval from the Security Executive Agent.9GovInfo. Executive Order 13467 – Reforming Processes Related to Suitability for Government Employment, Fitness for Contractor Employees, and Eligibility for Access to Classified National Security Information Security Executive Agent Directive 7 implements this by requiring agencies to check existing databases before initiating new investigations.10Office of the Director of National Intelligence. Security Executive Agent Directive 7 – Reciprocity of Background Investigations and National Security Adjudicative Determinations
Reciprocity has limits. Under SEAD 7, an agency is not required to accept your existing clearance if:
- New derogatory information has surfaced since your last investigation.
- Your most recent background investigation is more than seven years old.
- Your clearance was originally granted with an exception under SEAD 4.
- The new position requires a polygraph you haven’t taken.
- You need a higher clearance level than you currently hold.
- A Bond Amendment disqualifier applies.
SCI and SAP access often require separate adjudication and may not transfer even when the underlying Top Secret clearance does. Reciprocity works smoothly for straightforward lateral moves. It gets complicated when agencies have different risk tolerances or incompatible database systems.
If Your Clearance Is Denied or Revoked
If the government decides your record raises unresolved security concerns, you receive a Statement of Reasons (SOR), a formal notice identifying the specific adjudicative guidelines and factual allegations blocking a favorable determination. The SOR marks the point where the burden shifts to you: you have to show the concerns can be mitigated.
Your response addresses each allegation individually, admitting or denying it, and provides supporting evidence of mitigation. For DoD industry cases, if you choose not to request a hearing, the case proceeds on written submissions alone, and you have 30 days to respond to the government’s File of Relevant Material.11Defense Office of Hearings and Appeals. Overview of DOHAs Industrial Security Mission
If the case goes to a hearing, the Defense Office of Hearings and Appeals assigns an Administrative Judge. Opening statements, evidence and witnesses, closing arguments, and then a written decision. If the outcome is unfavorable, you have 15 days from the date on the decision to file a notice of appeal to the DOHA Appeal Board.11Defense Office of Hearings and Appeals. Overview of DOHAs Industrial Security Mission The Appeal Board does not re-hear the case; it reviews only whether the judge made a legal error, exhibited bias, or committed procedural irregularities. Attorneys who specialize in clearance cases generally charge between $162 and $392 per hour.
Keeping an active clearance is less about a single event and more about a set of habits: reporting what SEAD 3 tells you to report, treating financial and personal changes as security events rather than private matters, and moving carefully when you change jobs so the status you worked months to earn doesn’t quietly slip out of your hands.
