Processing figures move quarterly and vary by agency, contract, and case complexity. The numbers here are the most recent published data and should be treated as planning ranges, not promises. Your facility security officer or agency security office has the figures that actually apply to your case.
I What an interim actually is
An interim — formally a temporary eligibility determination — permits access to classified information before the background investigation closes. It is granted on the strength of preliminary record checks: the SF-86, automated database checks, credit, criminal history. No subject interview, no field work, no reference contacts.
That construction explains everything else about it. Because the basis is thin, the decision is fast. Because the basis is thin, the decision is provisional. Employers lean on interims constantly, since they let a new hire begin sensitive work weeks or months before an investigation completes.
It is not a final clearance and does not carry everything one does. Access may be narrower, some programmes will not accept it, and withdrawal does not follow the procedural process that denial or revocation of a final clearance requires. Do not describe yourself as “cleared” on the strength of an interim.
II The one-year cap
Under the NISPOM rule at 32 CFR 117.10, a temporary eligibility determination cannot exceed one year without approval from the applicable authority.
Read that carefully. It is one year of validity, not one year of active work. The clock runs from the grant, through every pause in the investigation, through every week you spend waiting on an investigator's schedule. If the investigation has not closed when the year runs out, the applicable authority must approve an extension or your access lapses.
Where the year goes
Interim granted in March. Work begins immediately. In August an investigator requests documentation of a foreign contact and a clarifying interview.
III What stops an interim cold
Three issue categories account for most interim denials.
| Issue | Effect on the interim | Why |
|---|---|---|
| Recent illegal drug use | Near-automatic denial | How recent is too recent depends on substance and agency |
| Foreign contacts or influence | Usually deferred to full investigation | Especially ties in countries of concern |
| Incomplete or inconsistent SF-86 | Stops it outright | Omissions and contradictions are exactly what preliminary checks catch |
| Significant unresolved debt | Commonly held or denied | Guideline F is the most frequent basis for adverse action |
| Undisclosed arrest | Stops it | The omission is worse than the underlying fact |
A disclosed issue is a fact the adjudicator weighs. An undisclosed issue found in the records is a candour problem layered on top of the original one, and candour concerns are far harder to mitigate. Your SF-86 accuracy is the single variable you fully control, and it is what keeps a temporary grant from being withdrawn before it becomes final. Financial issues specifically are covered in Guideline F.
IV An interim denial is not a final denial
This is the most misunderstood point in the whole process, and the misunderstanding costs people jobs they would have kept.
An interim denial means the preliminary checks flagged something an adjudicator is unwilling to resolve without a completed investigation. It means no early access. It is not an adverse determination on your eligibility, it does not carry the procedural consequences of one, and the full investigation continues normally.
Many people denied an interim receive a favourable final determination once the record is complete. Formal denial of a final clearance remains uncommon — on the order of one to two percent of cases — though a larger number are withdrawn, delayed, or abandoned before decision.
Some employers pause or withdraw offers on interim results alone, because a funded seat sitting empty for eight months is expensive. That is a business decision, not a security determination. If an offer is at risk, it is worth telling the employer plainly that an interim denial is a timing outcome rather than an eligibility outcome — many hiring managers do not know the difference.
V How an interim gets pulled
An interim can be withdrawn mid-investigation. The field work reaches sources the preliminary checks never touch — references, neighbours, former supervisors, the subject interview itself — and anything surfacing there can end the temporary grant.
Common triggers: an old issue emerging in interview testimony, a newly reported debt or arrest, an undisclosed foreign contact, or a discrepancy between what you wrote and what investigators find.
Withdrawal of an interim does not follow the process that revoking a final clearance requires. There is no Statement of Reasons, no hearing right, no DOHA appeal attached to the withdrawal itself. That asymmetry is why an interim is genuinely provisional and why the accuracy of your submission matters more during this window than at any other point.
Separately, once you hold eligibility, continuous vetting monitors it on an ongoing basis, and that machinery has its own alert and review process.
VI Interim Prospects Estimator
Enter what your SF-86 discloses. The estimator gives a read on interim prospects and a planning range for the full investigation.
What Are My Interim Prospects?
Planning estimates only. Adjudication is individualised under the whole-person concept, and nothing here predicts an adjudicator's decision on your file.
VII What the full investigation takes now
Materially better than the backlog years, and still long enough to plan around.
| Measure | Secret — Tier 3 | Top Secret — Tier 5 |
|---|---|---|
| DCSA published end-to-end average | 90–120 days | 180–365 days |
| Fastest 90% of cases, FY2026 Q1 | ~156 days | ~227 days |
| Investigation phase alone | ~60–150 days | ~120–240 days |
For context on how far this has moved: during the 2017–2019 crisis, Top Secret cases routinely ran past 400 days and the queue at the legacy National Background Investigations Bureau peaked around 725,000 cases. The investigations inventory has fallen roughly 65 percent since the start of 2025.
GAO has noted that average times for initial Top Secret cases drifted longer across fiscal 2022 through 2025. The recent quarterly improvement therefore sits on top of a multi-year climb rather than representing a clean decline. Plan for the upper end of the range, not the average.
VIII Reciprocity and transfers
If you already hold eligibility, moving it is faster than starting over — but slower than the policy promises. The stated aim of Trusted Workforce 2.0 is “clear once, trusted everywhere.” In practice a transfer that should take 30 to 75 days commonly runs 90 to 150, because files move between agencies and each receiving security office conducts its own review.
A GAO survey of contractors in 2025 found 40 percent seeing at least some improvement in requesting clearances and 45 percent reporting quicker interim determinations — while 52 percent still struggled to get information about investigations already under way. That last figure is the one that shapes the experience: the process is faster than it was, and it is still opaque while you are inside it.
IX The playbook
| Situation | What to do |
|---|---|
| Filling out the SF-86 | Disclose everything. An omission found later is worse than the fact omitted. |
| Uncertain about a date or address | Say so on the form rather than guessing. Gaps you flag are not the same as gaps they find. |
| Interim granted | Note the date. The one-year cap runs from the grant, not from your start date. |
| Investigator requests documents | Respond immediately. Your response speed is the part of the timeline you control. |
| Interim denied | Not a final denial. The investigation continues. Say so to your employer. |
| Employer wavering on the offer | Explain that an interim outcome is about timing, not eligibility. Many managers do not know. |
| Interim withdrawn mid-case | Ask what surfaced. Withdrawal does not carry SOR or hearing rights, but you can still respond to the underlying issue. |
| Recent drug use | Expect no interim. Plan for the full timeline and disclose completely. |
| Transferring an existing clearance | Plan for 90–150 days, not the 30–75 the policy implies. |
| Approaching the one-year mark | Ask your security office about extension approval before it lapses, not after. |
While the investigation runs
- Record the date your interim was granted and calendar the one-year mark.
- Keep a copy of your submitted SF-86 so you can answer consistently later.
- Respond to any investigator request within days, not weeks.
- Report anything newly reportable rather than waiting to be asked.
- Resolve or document a repayment plan for any outstanding debt.
- Track foreign contacts and travel as they happen.
- Ask your security office where the case stands before the year is up.
- Do not describe an interim as a clearance on a resume or profile.
- If the interim is denied, confirm in writing that the investigation continues.
- If it is withdrawn, ask what changed and keep the answer.
Frequently asked questions
It is a temporary eligibility determination that lets you begin classified work before the full background investigation finishes. It rests on preliminary record checks rather than a completed investigation, which is why it can be granted quickly and why it can be withdrawn quickly. Under the NISPOM rule at 32 CFR 117.10 a temporary eligibility determination cannot exceed one year without approval from the applicable authority. Treat it as a bridge onto the work, not as the finished credential.
When the preliminary checks turn up nothing adverse, an interim determination for Secret or Top Secret eligibility often arrives within roughly one to two weeks of submitting the SF-86. That depends on the agency, its current volume, and whether your application is straightforward. Anything requiring a second look, such as a prior arrest, foreign contacts, or credit problems, will either slow the interim or result in its denial while the full investigation continues in the background.
Three things dominate. Recent illegal drug use disclosed on the SF-86 is close to an automatic interim denial, with how recent is too recent depending on the substance and the agency. Close ties to foreign nationals, particularly in countries of concern, usually cause adjudicators to wait for the full investigation rather than grant early access. And an incomplete or inconsistent SF-86 stops an interim outright, because omissions, unexplained gaps, and answers contradicted by the records checks are exactly what the preliminary review is designed to catch.
No, and this is the most important thing to understand about it. An interim denial means the quick checks flagged something the adjudicator is unwilling to resolve without a completed investigation. It means no early access, not a final adverse determination. The full investigation continues, and a substantial share of people denied an interim receive a favourable final determination once the record is complete. What it does mean in practice is a delay, and some employers pause or withdraw offers on interim results alone, which is a commercial reality rather than a security one.
Yes. An interim is a temporary grant resting on incomplete information, so it can be withdrawn the moment the field investigation surfaces something the preliminary checks missed. An old issue appearing in interview testimony, a newly reported debt, an arrest, or a discrepancy between your SF-86 and what investigators find can all pull it. Withdrawal of an interim is not the same as revocation of a final clearance and does not carry the same procedural process, which is one reason it can happen quickly.
Meaningfully faster than during the backlog years, but not fast. DCSA data for early fiscal year 2026 showed end-to-end processing at the fastest 90 percent of cases of roughly 156 days for Secret and 227 days for Top Secret, and the agency's published end-to-end averages run about 90 to 120 days for Secret Tier 3 cases and 180 to 365 days for Top Secret Tier 5. The investigations inventory has fallen sharply since the start of 2025. Note the caution GAO has raised: average times for initial Top Secret cases drifted longer across fiscal 2022 through 2025, so recent improvement sits on top of a multi-year climb rather than a clean decline.
The one-year cap under 32 CFR 117.10 is on the validity of the temporary determination, not on your active work time. If the investigation has not closed by then, the applicable authority must approve an extension or your access lapses. Delays you cause make this worse: when investigators request interviews, documents, or clarification and you are slow to respond, the investigation stretches and your interim can expire while it is still open. Responding promptly is the part of the timeline you actually control.
Partly. The stated aim of Trusted Workforce 2.0 is clear once, trusted everywhere, and transferring an existing eligibility is faster than a fresh investigation. In practice a transfer that policy suggests should take 30 to 75 days often runs 90 to 150 because of file transfers and security reviews between agencies. Plan for the longer figure. A GAO survey of contractors in 2025 found improvement in requesting clearances and in interim determinations, but a majority still reported difficulty getting information about investigations already under way.
