Under the traditional schedule, security clearances are reinvestigated every 5 years for Top Secret, every 10 years for Secret, and every 15 years for Confidential. Those fixed cycles are being phased out. The federal government is replacing periodic reinvestigations with Continuous Vetting, an automated system that checks clearance holders against criminal, financial, terrorism, and other databases on a rolling basis. If you’re enrolled in Continuous Vetting, there is no calendar-driven reinvestigation at all. Whether you still fall under the old schedule depends on your agency and where the rollout stands.
The Traditional 5, 10, and 15-Year Cycles
For decades the timelines were straightforward. Top Secret required a fresh investigation every 5 years, Secret every 10 years, and Confidential every 15 years. The logic tracked the damage that unauthorized disclosure could cause. Top Secret information could cause “exceptionally grave damage” to national security, so the government looked more often at the people who had access to it.
These intervals still apply to anyone not yet enrolled in Continuous Vetting. If your agency hasn’t transitioned you, your next reinvestigation will follow the traditional schedule for your clearance level.
Continuous Vetting Replaces the Calendar
Continuous Vetting is the centerpiece of Trusted Workforce 2.0, a government-wide reform that changes how the federal government decides whether someone should keep a clearance. Instead of waiting 5 or 10 years to take another look, the system pulls data from criminal databases, terrorism watchlists, financial records, and other public records on an ongoing basis. If something concerning surfaces, it triggers a review right away rather than sitting undetected until the next scheduled reinvestigation.
Under Continuous Vetting, periodic reinvestigations are no longer required. Clearance holders still periodically update their personal information through vetting questionnaires, and additional investigations can still be triggered by what the system finds, but the old calendar-driven cycle goes away entirely for enrolled individuals.1Center for Development of Security Excellence.

The rollout is not yet complete. The national security population has largely been enrolled, and non-sensitive public trust workers are currently being onboarded. The government’s target for enrolling the full federal workforce is September 2028.2Performance.gov.

How to Tell Which System You’re On
If you hold a clearance and aren’t sure whether you’ve been enrolled in Continuous Vetting, ask your facility security officer. They can tell you whether your agency has transitioned and what your current vetting cycle looks like. Most of the national security workforce is already enrolled, so for a large share of clearance holders the honest answer to “how often” is: not on a schedule anymore, but potentially at any moment if monitoring flags something.
Events That Trigger a Review at Any Time
Even under the traditional schedule, the government never had to wait for the clock to run out. Certain life events can prompt a review at any time, and under Continuous Vetting many of these triggers are detected automatically instead of relying on self-reporting.
Financial problems are the single most common issue that surfaces during reinvestigations and ongoing monitoring. Bankruptcy, delinquent debts, tax liens, wage garnishments, and unexplained financial windfalls can all prompt closer scrutiny. The concern is that severe financial pressure can make someone vulnerable to bribery or coercion, not that debt itself makes someone a bad person.4Nuclear Regulatory Commission. Required Reporting for Clearance Holders
Other common triggers include arrests, charges, or criminal conduct whether or not they lead to a conviction; close or continuing relationships with foreign nationals and travel to sensitive countries outside official duties; a move into a role requiring higher-level access; and any new adverse information suggesting the holder may no longer meet eligibility standards, from substance abuse to security violations.
All of this is evaluated under 13 adjudicative guidelines covering areas like allegiance, foreign influence, financial considerations, criminal conduct, drug involvement, and personal conduct.5eCFR. Title 32 Part 147 – Adjudicative Guidelines for Determining Eligibility for Access to Classified Information No single issue is automatically disqualifying. Adjudicators weigh the seriousness, recency, and frequency of a concern against the person’s overall record under what the government calls the “whole person” concept.6Defense Counterintelligence and Security Agency.

Clearance holders are also required to report certain events on their own, without waiting to be asked. This obligation exists under Security Executive Agent Directive 3 and applies whether or not you’re enrolled in Continuous Vetting.7Office 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 Foreign travel must be reported in advance, and unplanned trips reported within five business days of return. Bankruptcy, foreclosure, tax liens, garnishment, debts more than 120 days delinquent, and any unusual influx of $10,000 or more must also be reported. So must arrests and changes in personal status such as marriage, divorce, cohabitation, or citizenship. Unreported issues that surface later look far worse than reported issues addressed honestly up front.
What a Reinvestigation Actually Involves
When a reinvestigation kicks off, whether triggered by the traditional schedule or flagged through Continuous Vetting, it starts with updated personal information. You’ll complete the Standard Form 86, a detailed questionnaire covering employment history, residences, foreign contacts, financial records, and other background information.8Office of Personnel Management. Standard Form 86 Questionnaire for National Security Positions The form is submitted electronically and builds on information already on file if you’ve filled one out before.
Investigators then verify what you reported. For Secret-level reinvestigations, this may involve automated record checks against criminal, credit, and other databases. Top Secret reinvestigations are more hands-on and typically include personal interviews with you and people who know you, such as coworkers, neighbors, and former supervisors. An adjudicator reviews the full picture, weighing favorable and unfavorable information under the adjudicative guidelines and whole-person framework.6Defense Counterintelligence and Security Agency.

Your sponsoring agency or the Defense Counterintelligence and Security Agency pays for the investigation. You don’t pay out of pocket, and you generally retain your clearance and access while the reinvestigation is pending, unless something has specifically triggered a suspension.
Breaks in Service and the 24-Month Limit
Eligibility doesn’t expire the moment you leave a cleared job, but it doesn’t last forever either. A break in service of 24 months or more means your old clearance can no longer be reinstated, and at that point you’ll need a completely new investigation to regain eligibility.9Center for Development of Security Excellence. Customer Service Requests and Incident Report Management Return within that window and your agency can request recertification of your existing eligibility without starting over. Separately, agencies are required to accept another agency’s properly adjudicated clearance at the same or higher level under reciprocity rules, but that reciprocity has its own limits: it does not apply if the most recent investigation is more than seven years old, if new adverse information has surfaced, or if the clearance is interim, suspended, denied, or revoked.10Office of the Director of National Intelligence.
