Security clearance adjudication usually takes somewhere between nine and twenty days once the completed investigation reaches an adjudicator. During the second quarter of Fiscal Year 2024, the Defense Counterintelligence and Security Agency (DCSA) reported Top Secret adjudication averaging roughly 20 days, and by the third quarter of Fiscal Year 2025 overall adjudication was averaging around nine days in some categories. Complex cases run longer, sometimes months, but adjudication itself is almost always the shortest phase of getting a clearance. The long wait most applicants experience happens earlier, during the background investigation.
What Adjudicators Are Doing
Once federal investigators finish gathering information, your file goes to trained adjudicators at a Central Adjudications Facility. DCSA handles the bulk of Department of Defense personnel vetting. The adjudicator weighs the file against national guidelines set out in Security Executive Agent Directive 4 (SEAD 4), which lists 13 categories ranging from allegiance and foreign influence to financial considerations, drug involvement, and personal conduct.
Adjudicators use a “whole person” approach. They don’t treat any single red flag as automatically disqualifying, and they weigh favorable information against unfavorable information from across your life to decide whether granting access to classified material is consistent with national security.1Defense Counterintelligence and Security Agency. Trust Decision (Adjudications) A clean file moves quickly. A file with questions attached to it takes longer because those questions have to be worked through.
Where Adjudication Fits in the Total Wait
If you’re counting the days since you submitted your SF-86, most of that time is investigation, not adjudication. The federal government tracks end-to-end timing that combines initiation, investigation, and adjudication into a single figure. By the fourth quarter of Fiscal Year 2024, the average end-to-end time for Top Secret clearances was 249 days. For Secret clearances it was 138 days. Those figures cover the fastest 90% of applications.2Performance.gov. Trusted Workforce 2.0 Quarterly Progress Report
More recent data shows investigation timeliness continuing to improve, reaching 109 days for high-risk cases and 59 days for moderate-risk cases by early FY2026.3Performance.gov. Trusted Workforce 2.0 Quarterly Progress Report – FY26 Q1 Under the Trusted Workforce 2.0 targets, adjudication is supposed to take 10 days for moderate-risk positions and 15 days for high-risk positions. The government acknowledges it remains behind those targets overall, though the direction has been improving. DCSA’s investigation backlog peaked at roughly 290,000 cases in September 2024 and had fallen to about 222,000 by May 2025, a 24% reduction that has helped push adjudication averages down.
What Can Slow Adjudication Down
A clean file with no complications can be adjudicated in under two weeks. Cases with complications can sit for months. A few things tend to be responsible.
Foreign Contacts and Travel
Extensive foreign travel, close relationships with foreign nationals, and immediate family living abroad trigger heightened scrutiny under SEAD 4’s Foreign Influence and Foreign Preference guidelines.4DNI.gov. Security Executive Agent Directive 4 – National Security Adjudicative Guidelines Adjudicators may need to verify the nature of each relationship and assess whether a foreign government could use those connections as leverage. A file with dozens of foreign contacts takes longer than one with none.
Financial Problems
Financial issues are one of the most common reasons adjudication stalls. Significant debt, bankruptcy filings, tax liens, and patterns of missed payments raise concerns about reliability and vulnerability to coercion. The adjudicator isn’t just checking whether you’ve had financial trouble. They’re evaluating whether you’ve taken steps to resolve it and whether the pattern suggests irresponsibility or bad luck.
Drug Use, Including Marijuana
Past use of illegal drugs falls under Guideline H. Marijuana deserves specific attention because many applicants assume state legalization changes the federal calculation. It does not. Marijuana remains a controlled substance under federal law, and the adjudicative guidelines follow federal law exclusively.5CDSE. Adjudicative Guideline H – Drug Involvement and Substance Misuse Short Student Guide That treatment extends to CBD products and hemp derivatives containing more than 0.3% THC. Past recreational use isn’t an automatic bar, but frequency, recency, and credible evidence you’ve stopped all factor in. Lying about it on the SF-86 is far more damaging than disclosing it.
SF-86 Discrepancies
When what you wrote on the SF-86 doesn’t match what investigators find, the adjudicator has to figure out why. Some gaps are innocent, like a forgotten short-term employer from years ago. Others look like deliberate omissions and create serious problems. Either way, the adjudicator may request clarification from you or send the case back for additional investigation, both of which add weeks or months. Filling out the SF-86 thoroughly and honestly the first time is the single best thing you can do to keep adjudication moving.
Agency Workload
Even a straightforward case can sit in a queue if the adjudicating agency is overwhelmed. Investigations drive most of the backlog, but periods of high volume affect every phase of the pipeline, and adjudication averages fluctuate quarter to quarter as a result.
Interim Clearances While You Wait
Because the full process takes months, many applicants receive an interim clearance that lets them start work on classified projects before final adjudication is complete. DCSA routinely considers all contractor applicants for interim eligibility as part of the normal process.
An interim is based on a quick review of a few early data points rather than the full investigation: a favorable review of the SF-86, a favorable fingerprint check, proof of U.S. citizenship, and where applicable a favorable local records review. If all four come back clean, an interim clearance can be granted within days of submission.6Defense Counterintelligence and Security Agency. Interim Clearances An interim isn’t a guarantee the final adjudication will go the same way. If the full investigation later turns up disqualifying information, the interim can be revoked and the final clearance denied.
How to Check Where Your Case Stands
You cannot call DCSA directly and ask about your case. DCSA will only discuss clearance and adjudication status with authorized security contacts at your sponsoring organization. Active-duty military should contact the security officer at their duty station. Federal civilians and contractors should contact the facility security officer (FSO) at their employer or the security office at their hiring agency.7Defense Counterintelligence and Security Agency. Check Your Status Your FSO has access to the Defense Information System for Security and can tell you whether your case is in investigation, in adjudication, or complete.
If the adjudicator sends you a request for additional information, respond promptly. Delays caused by slow applicant responses are among the most avoidable reasons a case stalls.
If Adjudication Doesn’t Go Your Way
The vast majority of applications end in a favorable decision. Exact denial rates aren’t officially published, but available data suggests roughly 2% to 5% of applications end in denial or revocation. If the adjudicator identifies security concerns that aren’t adequately mitigated by information already in your file, you’ll receive a Statement of Reasons (SOR). This formal letter spells out the specific concerns under the relevant SEAD 4 guidelines and explains why the government intends to deny or revoke your clearance.8Central Intelligence Agency. Statement of Reasons
An SOR is not a final denial. You have 20 days from receipt to submit a detailed written response under oath addressing each specific allegation, and you can request a hearing before a Defense Office of Hearings and Appeals administrative judge in that same response.9eCFR. 32 CFR Part 155 – Defense Industrial Personnel Security Clearance Program Failing to respond within 20 days can result in the case being discontinued and the clearance denied. If you receive an SOR, treat the 20-day clock as the most important date in your file.
