If you are hiring for a cleared defense role in 2026, the clearance timeline is the part of the plan most founders get wrong, and it is the part most likely to leave a funded seat empty for months. A new Secret clearance runs roughly 1 to 6 months. Top Secret runs 4 to 12. TS/SCI runs 6 to 18, and if the role needs a full-scope polygraph, the elapsed time can stretch to 14 to 22 months. The single most expensive mistake is assuming a "clearable" candidate is almost as good as a cleared one. They are not close, and the gap is measured in quarters, not weeks.
This is not a paperwork problem you can speed up by trying harder. It is a planning problem. The companies that staff cleared roles well are the ones that treat the clearance timeline as a fixed input they design around, not a surprise they discover after the offer.
The Numbers to Plan Against, and the Numbers Not To
Two different sets of clearance numbers circulate, and confusing them is how hiring plans break. Use the planning ranges below to build a schedule. Do not build a schedule on the official published averages, for reasons this guide covers in detail in the next section.
PLAN AGAINST THESE RANGES. Secret (Tier 3): roughly 1 to 6 months, with straightforward cases now closing in about 55 to 90 days. Top Secret (Tier 5): roughly 4 to 12 months, with DCSA's published end-to-end range for FY2026 running about 180 to 365 days from submission to final eligibility. TS/SCI: roughly 6 to 18 months, since SCI adjudication adds about 60 to 180 days on top of the Top Secret investigation. TS/SCI with full-scope polygraph: can reach 14 to 22 months elapsed at agencies like NSA and CIA, where the polygraph waitlist is now the main bottleneck. (Sources: ClearedJobs.Net 2026 clearance timelines; ClearedJobs.net Security Clearance Guide 2026; CCS Global Tech / iQuasar 2026.)
DO NOT PLAN AGAINST THESE. DCSA publishes Top Secret processing at 227 days and Secret at 156 days for the fastest 90 percent of cases in Q1 FY2026, and an overall end-to-end average of about 243 days as of Q3 FY2025. Those are real, official figures and they are useful for understanding direction of travel. They are not planning numbers. They are stale on arrival, they describe the fastest 90 percent rather than your candidate, and they blend case types that behave nothing alike. The rest of this section explains why.
This guide breaks down the real clearance processing landscape in 2026, why the official numbers understate the problem, and how defense tech companies plan around it without losing ground to competitors who started the process earlier. For context on what is driving the surge in cleared hiring demand, see our coverage of the Golden Dome program and defense tech hiring.
What DCSA Actually Publishes and What It Means
The Defense Counterintelligence and Security Agency publishes quarterly clearance processing data through the National Industrial Security Program Policy Advisory Committee, known as NISPPAC.
The most recent published data shows Top Secret clearance processing at 227 days and Secret clearance processing at 156 days for the fastest 90 percent of cases in Q1 FY2026.
Those numbers have two problems that make them operationally misleading for hiring managers.
The data is 4 to 6 months stale at publication. Q1 FY2026 covers October through December 2025. The figures published in March 2026 reflect a processing environment that existed months before you read them. Adjudication staffing levels, application volumes, and continuous vetting implementation all affect timelines and all change quarter to quarter. By the time you are building your hiring plan around the published number, you are planning around historical data.
The published figure is the fastest 90 percent, not the average. The 227-day figure means 90 percent of Top Secret cases processed in that quarter completed within 227 days. It says nothing about the remaining 10 percent. And within that 90 percent, the distribution is wide. Some candidates clear in 90 days. Others take 300. The published figure gives you no visibility into which outcome you should expect for a specific candidate.
What defense tech hiring managers need for operational planning is not DCSA's published average. It is a realistic range that accounts for the variability the published figure obscures.
That range for TS in 2026 is 6 to 12 months. For TS/SCI it runs longer. For TS/SCI with polygraph, plan for 12 to 18 months for candidates who do not already hold that level.
Why Clearance Timelines Are Longer Than They Appear
Several factors compound to make real-world clearance timelines longer than the DCSA average suggests.
Adjudication timelines increased even as investigation timelines improved. DCSA's Q1 FY2026 data shows investigation processing improving year over year. In the same period, adjudication timelines increased. A faster investigation that sits in an adjudication queue for months produces no net improvement for the hiring manager waiting on a start date.
Trusted Workforce 2.0 implementation is uneven. Trusted Workforce 2.0 was designed to modernize and accelerate the clearance process through continuous vetting and reciprocity improvements. In practice, adoption has been inconsistent across agencies and program offices. A 2026 employer whitepaper from ClearanceJobs found that 52 percent of contractors struggle to obtain information on ongoing investigations and 35 percent report problems with continuous vetting alerts. For defense tech startups without a dedicated Facility Security Officer, these friction points add invisible time to every clearance action.
Individual case complexity varies widely. A candidate with a clean record, no foreign contacts, no financial issues, and prior cleared employment clears faster than a candidate with any of those factors in their background. DCSA's published average blends all of these cases together. The candidates most likely to clear quickly are also the ones most aggressively recruited, which means the candidates available in the market may skew toward the slower end of the distribution.
Polygraph requirements create separate bottlenecks. TS/SCI with full-scope polygraph is required for many signals intelligence, counterintelligence, and intelligence community programs. The polygraph pipeline is separate from the investigation and adjudication pipeline and has its own scheduling constraints. Candidates requiring a polygraph face wait times that can add months beyond the TS/SCI adjudication timeline.
The Three Clearance Scenarios and How to Plan for Each
Not every hire at a defense tech startup requires the same clearance path. Understanding the three common scenarios changes how you build your hiring plan.
Scenario 1: Candidate holds an active clearance at the required level
This is the fastest path and the most competitive market. Candidates with active TS/SCI clearances are the most sought-after profiles in the defense tech talent market. They command premium compensation, have multiple options, and make decisions quickly.
If your candidate holds an active clearance at the required level, your clearance timeline is measured in weeks, not months. The primary variable is reciprocity: whether your program office will accept the candidate's existing clearance or require a reinvestigation.
The hiring implication: move fast. A candidate with an active TS/SCI who is in your pipeline is also in three other companies' pipelines. Slow interview processes lose these candidates to companies that make decisions in two weeks instead of two months.
Scenario 2: Candidate holds a clearance but needs an upgrade
A candidate with an active Secret clearance who needs TS/SCI for your program needs an upgrade investigation and adjudication. The existing clearance history accelerates the process relative to a first-time clearance but does not eliminate the wait.
Realistic planning timeline for a Secret to TS/SCI upgrade in 2026: 4 to 8 months from sponsorship initiation to adjudication. The range is wide because prior clearance history, personal circumstances, and current adjudication queue depth all affect the outcome.
The hiring implication: you can hire this candidate into a role with interim duties that do not require TS/SCI access while the upgrade processes, or you can accept a program gap. Neither is ideal. The companies that plan around this scenario build their interim work scope before the offer is extended.
Scenario 3: Candidate requires an initial clearance
A candidate with no prior clearance history requires the full investigation and adjudication process from scratch. For a TS/SCI, the realistic planning timeline is 9 to 15 months in 2026. For TS/SCI with polygraph, 12 to 18 months.
The hiring implication: this scenario is only viable if you have a genuine 12-month runway before the role requires full classified access, or if the candidate can contribute meaningfully at lower classification levels during the processing period. Defense tech startups that hire uncleared candidates into roles requiring immediate TS/SCI access create program risk they often do not account for until it is too late.
How Fast-Moving Defense Tech Companies Plan Around Clearance Timelines
The defense tech companies that never miss a program milestone because of clearance-driven hiring delays share a common approach.
They start the clearance process before the formal hire. The fastest path to a cleared hire is finding candidates who are already in process or whose prior clearance history makes the timeline predictable. The second fastest path is initiating sponsorship as early in the hiring process as possible. Companies that wait until a candidate accepts an offer before initiating clearance sponsorship add months to their timeline unnecessarily.
They maintain a pipeline of cleared candidates separate from active reqs. The best defense tech recruiting operations treat cleared candidate pipeline as infrastructure. They identify and stay in contact with cleared professionals who are not actively looking but whose profile matches upcoming program needs. When a req opens, they have somewhere to start instead of starting from zero.
They build clearance timeline assumptions into program planning. A program plan that assumes a key hire will be cleared and on-seat in 90 days when the realistic timeline is 9 months is not a program plan. It is a risk that will surface at the worst possible moment. The defense tech companies with the most predictable execution build clearance processing timelines into their program schedules the same way they build hardware lead times into their procurement plans.
They use SkillBridge to access transitioning military talent with active clearances. Transitioning service members represent one of the most reliable pipelines of recently adjudicated cleared talent available to pre-IPO companies. A SkillBridge participant separating from service with an active TS/SCI brings a clearance that typically transfers within weeks rather than months. Defense tech startups with active SkillBridge programs have a structural advantage in cleared talent access.
They work with specialized cleared recruiting partners. A recruiter who operates exclusively in the cleared talent market has visibility into candidates whose clearance status, eligibility, and timeline are already known. The difference between starting a cleared search with a warm pipeline versus starting from a job posting is often the difference between a 45-day fill and a 6-month search.
Why "Clearable" Does Not Mean Quick
This is the mistake I see most often. A founder finds a strong candidate who "can obtain" a clearance, treats that as roughly equivalent to a cleared hire, and builds the plan around a start date that assumes the clearance is a formality. It is not a formality. It is the longest pole in the tent.
A clearable candidate is not a few weeks behind a cleared one. Depending on the level and whether a polygraph is involved, they are months to well over a year behind, and during that entire stretch the funded role sits open, the program runs understaffed, and the candidate is either waiting on interim status or doing unclassified work if you have any to give them. Nobody did anything wrong. The timeline alone creates the cost.
An already-cleared candidate starts contributing now. That is why, priced honestly against the cost of a seat sitting empty for two or three quarters, the cleared candidate is often the cheaper hire even at a higher salary. The clearance is the asset. Treat it that way in your planning and your budget, and see our 2026 cleared-talent compensation report for what that premium actually costs.
Reciprocity Helps, But Do Not Build the Plan On It
The stated goal of Trusted Workforce 2.0 is "clear once, trusted everywhere," and continuous vetting has genuinely reduced reinvestigation workload. Moving an already-cleared person between employers should be fast.
In practice it depends heavily on the agencies involved. A transfer that should take 30 to 75 days often runs 90 to 150 because of document transfer and security-file review between agencies. It is still far better than a fresh investigation, and it is a real advantage of hiring already-cleared talent. But it is not the instant handover the policy promised, and a hiring plan that assumes clean, fast reciprocity across agencies will sometimes be wrong. Plan for the better case, budget for the slower one.
The Real Bottleneck Is Starting Too Late
Most clearance pain does not come from DCSA. It comes from the search starting too late. A company waits until the program is funded and the need is urgent, then begins looking for cleared talent, and only then runs into a timeline that was always going to take months. The clearance did not fail. The planning did.
The fix is unglamorous: start the cleared search earlier than feels necessary, and treat the clearance timeline as a fixed input you design the hiring plan around. That means sponsoring early where you can, using interim clearances to bridge when the role allows, prioritizing already-cleared candidates for anything time-sensitive, and budgeting for the vacancy the timeline will create rather than being surprised by it. None of that speeds up DCSA. All of it keeps the timeline from wrecking your program schedule.
What to Plan For, By Situation
Time-sensitive role you cannot wait on: prioritize already-cleared candidates, and factor reciprocity at the slower end, up to about 150 days, not the promised 30 to 75.
Role you can plan ahead for: sponsor a strong clearable candidate early, and use interim clearance or unclassified work to bridge the investigation window.
TS/SCI with polygraph: assume the polygraph waitlist is the bottleneck and plan on the long end. This is the category where "clearable" costs the most.
Any cleared role: start the search before the seat is funded and urgent, not after. The earlier you start, the less the timeline controls you.
Continuous Vetting and What It Means for Retention
Trusted Workforce 2.0 introduced continuous vetting as a replacement for periodic reinvestigation. Instead of a five-year reinvestigation cycle, cleared personnel are now subject to ongoing automated record checks across financial, criminal, and other databases.
For hiring managers, continuous vetting has two practical implications.
First, it creates ongoing visibility into cleared employees' eligibility status. Issues that previously would have gone undetected until a reinvestigation now surface in real time. This is good for security. It also means that cleared employees may receive alerts or flags that require adjudication action mid-employment, creating temporary access interruptions that hiring managers need to plan around.
Second, the implementation is uneven. The 35 percent of contractors who report problems with continuous vetting alerts are largely dealing with false positives and administrative friction that requires FSO intervention to resolve. For defense tech startups without dedicated FSO infrastructure, this friction adds overhead that compounds with every cleared hire.
The operational implication is that cleared workforce management in 2026 requires more active administration than it did under the periodic reinvestigation model. Companies scaling their cleared workforce need to account for this overhead in their operations planning.
Where Clearance Requirements Concentrate
Clearance timelines bite hardest in the markets where cleared work concentrates. The corridor with the deepest cleared demand is Northern Virginia, where TS/SCI with polygraph is common. Colorado Springs runs roughly 14-month TS/SCI-with-poly timelines against on-site SCIF requirements, while Huntsville spans Secret through TS/SCI across its missile and space programs. On the coasts, San Diego and El Segundo and Los Angeles carry naval and military-space clearance requirements respectively, and Florida's Space Coast splits between uncleared commercial launch work and cleared defense-systems roles.

How ALAC Works Cleared Searches
We treat the clearance timeline as part of the search design, not an afterthought, because on a cleared role it is usually the thing that decides whether the seat gets filled on schedule. That means being honest with a client early about what the clearance reality does to the timeline, prioritizing already-cleared candidates when the role cannot wait, and planning the search around the constraint instead of pretending it is not there. On a recent set of nine RF and EE searches for a venture-backed defense company, every role was filled in under 45 days, because the search was built around the clearance reality from the start rather than colliding with it at the offer stage. Different, not better. If you are scoping a cleared role, book a call and we will tell you what the clearance timeline actually does to your plan. Most of this work runs through embedded recruiting.
Frequently Asked Questions
What is the fastest way to get an employee cleared to TS/SCI in 2026?
The fastest path is hiring a candidate who already holds an active TS/SCI clearance and whose clearance can be transferred to your facility through reciprocity. The second fastest is hiring a candidate with a prior Secret clearance and initiating the upgrade sponsorship as early as possible in the hiring process, ideally before the offer is extended. There is no fast path for an initial TS/SCI clearance. Plan for 9 to 15 months.
Can we hire someone uncleared and start the process after they join?
Yes, and many defense tech startups do this. The candidate works in unclassified environments while their clearance processes. This only works if you have genuine unclassified work they can contribute to during the processing period. Hiring an uncleared candidate into a role that requires immediate classified access is a program risk.
What happens to a veteran's clearance when they separate from the military?
An active clearance remains valid for a period after separation from military service, typically two years before it becomes inactive. A veteran separating with an active TS/SCI can transfer that clearance to a cleared defense contractor relatively quickly, subject to the new employer obtaining appropriate facility clearance. Veterans within the two-year window represent the most accessible cleared talent pipeline in the market.
What is the difference between a TS clearance and TS/SCI?
A Top Secret clearance grants access to information that could cause serious damage to national security if disclosed. TS/SCI, or Top Secret with Sensitive Compartmented Information access, grants access to classified information organized into compartments. SCI access requires a separate adjudication and, for some programs, a polygraph examination. Most defense tech startup roles that require classified access require TS/SCI rather than TS alone.
Does DOGE-related workforce reduction at DCSA affect clearance processing times?
Workforce reductions at federal agencies that affect adjudication staffing have historically correlated with longer processing times. Published data from DCSA has not yet reflected any impact from recent federal workforce changes, but the data lag means that effects from 2025 changes would appear in published figures months later. This is an open question that defense tech hiring managers should monitor through cleared industry resources like ClearanceJobs.com.
Conclusion
The clearance timeline is the most underestimated variable in defense tech hiring.
It is not 227 days. It is 6 to 12 months for TS, longer for TS/SCI with poly, and it starts from the moment you initiate sponsorship, not from the moment you extend an offer.
The defense tech companies that execute without clearance-driven program delays are the ones that plan for real timelines, build cleared candidate pipelines before they need them, and work with hiring cleared engineers partners who have existing relationships with candidates whose clearance status is already known.
