How Long Is a TS/SCI Clearance Good For? Continuous Vetting Rules

A TS/SCI clearance has traditionally been considered good for five years, the interval between periodic reinvestigations of the underlying Top Secret eligibility, but that answer is being overtaken by continuous vetting, which replaces the five-year checkup with ongoing automated monitoring.¹ Your eligibility stays valid as long as you hold a cleared position and nothing in the automated checks or your reporting raises a disqualifying concern. If you leave a cleared job, the eligibility goes inactive but can generally be reactivated within 24 months before a fresh investigation is needed.²

The Old Five-Year Rule

For decades, Top Secret clearance holders were subject to a periodic reinvestigation every five years, while Secret clearance holders were reinvestigated every ten.¹ That reinvestigation was a fresh background check covering financial records, criminal history, foreign contacts, and personal conduct since the last review.

SCI is not a separate clearance level. It is a control system that restricts access to intelligence sources and methods, granted on top of a Top Secret clearance by the sponsoring agency for specific compartments. When people ask how long a TS/SCI clearance is good for, they are asking about the Top Secret eligibility underneath, and the five-year figure is attached to that portion.

Continuous Vetting Has Replaced the Five-Year Cycle

Under the Trusted Workforce 2.0 initiative, continuous vetting now replaces those periodic reinvestigations with ongoing, automated monitoring.³ Instead of a full review every five years, the system pulls data from criminal, terrorism, financial, and public records databases on a rolling basis.⁴

As of early 2026, the entire national security population is enrolled in continuous vetting, and requests for old-style periodic reinvestigations have dropped by 99%. The reinvestigations that still occur are used mainly to resolve significant issues flagged by continuous vetting, not as routine five-year checkups. Full enrollment of the entire vetted federal workforce, including non-sensitive public trust positions, is targeted for September 2028.⁵

Practically, this changes what “good for” means. Your eligibility no longer sits untouched for five years. It stays valid indefinitely as long as continuous vetting shows nothing disqualifying and you continue to meet the standards. A concerning record hit can trigger a review at any time. Minor issues surfaced early are usually easier to mitigate than ones that build up and appear during a full reinvestigation, but there is no longer a quiet stretch where problems go unnoticed.

What Happens When You Leave a Cleared Job

Once you leave a position that requires a clearance, your TS/SCI eligibility goes inactive. You lose the ability to access classified information because you no longer have a need to know, but the underlying eligibility determination stays on file. If you return to a cleared position within 24 months, the clearance can generally be reactivated without starting from scratch.² The gaining agency reviews an updated security questionnaire and applicable records, but a full reinvestigation is not required unless that review raises concerns.⁶

After 24 months of continuous break, the clearance lapses. At that point a new employer would need to sponsor you for a fresh investigation. The new investigation will not necessarily run as long as your first one because you have a prior record of eligibility, but there is no guaranteed timeline. If you are transitioning out of a cleared role and expect to return, that 24-month window is worth tracking.

What Can End Your Eligibility Before Then

Duration assumes nothing changes. Your TS/SCI eligibility can be challenged at any time, and continuous vetting makes early challenges more likely than they used to be. Adjudicative guidelines under Security Executive Agent Directive 4 lay out the categories of concern that can lead to suspension or revocation.⁷ Suspension temporarily removes access while an issue is investigated; revocation is a final determination that you no longer meet the standards.

Financial problems are among the most common triggers. The concern is not being bad with money but that financial distress can make people vulnerable to coercion or bribery. A pattern of unpaid debts, unexplained wealth, or financial problems tied to gambling or substance abuse can all draw a review.⁷ There is no specific dollar amount or debt-to-income ratio that automatically triggers action; adjudicators look at the overall pattern.

Criminal activity, including arrests and allegations rather than only convictions, creates doubt about judgment and reliability.⁶ Under continuous vetting an arrest is likely to appear in automated checks quickly, so prompt self-reporting matters. Close ties to foreign nationals, foreign financial interests, and undisclosed foreign contacts are scrutinized heavily for SCI holders. Dual citizenship alone is not automatically disqualifying, but acquiring foreign citizenship, holding an undisclosed foreign passport, or failing to use your U.S. passport at the border can all raise concerns.

Reporting Requirements That Keep You in Good Standing

Holding a TS/SCI clearance carries ongoing reporting duties that do not stop between reviews. Security Executive Agent Directive 3 sets the baseline, and your agency may layer more on top.⁸ Failing to report a required event is itself a security concern, separate from the underlying event.

Planned unofficial foreign travel must be reported before departure, with destinations, dates, and itinerary.
Continuing associations with foreign nationals involving personal bonds, obligations, or intimate contact must be reported within three business days.
Applying for or receiving a foreign passport, foreign citizenship, foreign residency, or foreign employment must be reported within three business days.
Arrests, charges, and convictions must be reported as soon as possible.
Bankruptcy filings and other serious financial problems must be reported.
Changes in marital status, cohabitation, and legal name require reporting.

Specific deadlines vary by agency; some require reporting within five calendar days, while SEAD 3’s baseline for foreign contacts and activities is three business days.⁸ When in doubt, report sooner.

Moving Between Agencies Without Restarting the Clock

Federal policy requires agencies to accept each other’s clearance determinations under reciprocity, so cleared personnel can move between agencies and contractors without a fresh investigation.⁹ The gaining organization’s security office verifies your existing clearance and SCI access in a centralized database. For the Intelligence Community, that database is Scattered Castles.¹⁰ For Department of Defense positions, clearances are tracked through the Defense Information System for Security.

Reciprocity is not always seamless. If the new position requires access to a different SCI compartment than you previously held, additional vetting for that compartment may be needed. If the new agency requires a polygraph and your previous one did not, you will need to complete that step. Interim clearances are treated differently from final adjudications. An interim Top Secret is a provisional determination based on a favorable review of your security questionnaire and fingerprints while the full investigation is still pending, and interim eligibility does not grant SCI access.¹¹ In those cases the clock has not really started on a final clearance yet.
