You saw "TS/SCI with poly" on a posting and want a straight answer. Here is who takes one, which kind, and how anyone gets one in the first place.
You saw it on a posting. The line said "TS/SCI with poly," or maybe "CI poly required." So here is the question. Do I need a polygraph for a security clearance? For most cleared jobs, no. Here is the whole picture, including the parts nobody writes down.
Most cleared jobs need no polygraph. That includes most Top Secret jobs. A polygraph isn't a clearance level, and it isn't a higher grade of clearance. It's a separate thing some agencies attach to some jobs. Almost all of those jobs sit in the Intelligence Community, the IC, or in a handful of special programs at the Defense Department.
You get one the same way you get a clearance. You don't apply for it. A job that needs a polygraph puts you in for it. The agency behind that job runs the exam, not the company that hired you. There's no window, no fee, and no form you can file on your own.
So the useful question is never "do I need a polygraph." It's "does the job I want require one." Those are two different questions, and only the second one has an answer.
Job postings smash these together. Pull them apart and the language stops being confusing.
A clearance. Permission from the U.S. government to work with classified information. The levels are Confidential, Secret, and Top Secret. The job that sponsors you sets the level, not you.
SCI. Short for Sensitive Compartmented Information. It sits on top of a Top Secret. It covers specific compartments you're read in on for a need to know. You usually don't learn what a compartment is until your first day.
A polygraph. An exam. It measures physical responses while you answer specific questions. It's a screening step, not a level, and holding one isn't a clearance.
One more difference matters. Eligibility is the government deciding you can be trusted at a level. Access is being read on for a particular job. A polygraph is a condition on access. That's why two people can both hold a Top Secret when only one has ever sat for an exam.
Now the posting language makes sense. "TS/SCI" is Top Secret eligibility plus compartmented access. "TS/SCI with poly" is that plus a passed polygraph on file. Nothing about the clearance level tells you whether an exam is involved. Only the job tells you.
There are three types. The short forms land on postings with nothing to explain them.
Counterintelligence, or CI. The most common type by far. It covers foreign contacts, mishandling of sensitive information, and espionage-related risks. It's used across the IC, at agencies like DIA, NGA, and NRO, and some Defense Department special access programs use it too.
Lifestyle, or LS. The least common, and rarely taken by itself. It covers personal conduct: drug use, criminal activity, and anything that could leave you open to pressure. How past marijuana use is weighed is the same question here as it is on the form.
Full scope, often written FSP. CI and lifestyle combined into one exam. It's the most valuable one to hold, employers often pay more for it, and only a handful of agencies give it at all. NSA and CIA are the two that routinely require it before they'll give you access.
That last point is the one almost nobody spells out. People talk about full scope like it's the next rung on a ladder anyone can climb. It isn't. It's the entry condition at a very short list of agencies, and if you're not applying to one of them, it rarely comes up at all.
Reading a posting. When a job says "with poly" and stops there, it usually means CI, because CI is the common one. A job that wants full scope normally says so outright, as "full scope poly" or "FSP." And you often aren't told which exam you'll sit for, so the date can arrive before the details do.
The center of it is the IC and the contractors who support it. Nearly every IC job comes with clearance sponsorship attached, and many of them come with a polygraph too. Outside the IC, some Defense Department special access programs ask for a CI polygraph.
Everywhere else it rarely comes up. Confidential and Secret jobs hardly ever need one. Most Defense Department Top Secret jobs don't either, as long as they sit outside SCI and special programs. That covers a huge share of the cleared job market.
There's no master list to look up, and the rules change from contract to contract. The posting is the only reliable source. Read its clearance line first, before the duties and before the pay. That one line decides whether the rest of the posting applies to you.

The rule that governs clearances governs polygraphs too. You can't get one on your own. An employer sponsors you, and you get sponsored by landing a job that needs it.
Who runs the exam. The agency does, not your employer. When a contractor lists a polygraph, it's passing along what its government customer wants. The company isn't setting a bar of its own, which also means it can't schedule, waive, or speed up your exam. Anyone offering to sell you a polygraph for a clearance is selling something that can't be sold.
Where it falls in the process. After your SF-86, the questionnaire you fill out online once an employer submits you. The IC's own careers site puts the polygraph at step three of seven. That's after the questionnaire and before any medical or psychological exam. The rest of the investigation runs around it on the agency's schedule. The IC also says its full process averages nine to twelve months, and that holding a clearance already may not speed it up.
Are you a step earlier than this, with no clearance and no sponsor? Start with how clearance sponsorship actually works. Getting the job is the part you control.
This is the question I get most from people who are already cleared. You can't add one yourself, and you can't call an agency to book an exam. A polygraph gets added the same way the clearance itself arrived. A job needs it, and that employer puts you in for it.
What to apply to. Postings that say a polygraph is required. Also postings that say the employer will process you for one. On the contractor side those exist, and recruiters know which of their contracts can sponsor an exam. On the IC side, sponsorship comes standard with nearly every job.
What happens next. The sponsoring agency schedules the exam, and you keep working at the level you already hold for as long as it runs. Every clearance upgrade works this way: Secret to Top Secret, Top Secret to SCI, or a polygraph added. You're not sitting at home waiting.
A shortcut worth asking about. Some contracts let someone who already holds a CI polygraph start work on temporary access while the full-scope exam is scheduled. It varies contract by contract, so ask the recruiter or the facility security officer directly. Nobody volunteers this one.
If you're in uniform. Service members rarely get a full scope while on active duty. The CI polygraph is far more common on that side, and a full scope usually comes later, through an agency or a cleared contract.
What your Top Secret is doing meanwhile. Working for you. A Top Secret is in demand on its own, and it keeps opening doors while you go after more. What a polygraph changes is which recruiters can see you. In the IC market, the poly is the filter recruiters search on, and a posting that asks for one screens out everyone who doesn't hold it. That's about how those searches are built, not about your clearance.
Start with published survey numbers, then I'll give you my own read.
The 2026 ClearanceJobs compensation survey measured this directly. Cleared professionals with no polygraph averaged $118,680 in total compensation. With a CI polygraph the average was $148,128, and with a lifestyle or full-scope polygraph it came in at $149,875. Roughly thirty thousand dollars a year separates a poly from no poly in that data.
The same survey broke it out by clearance too. DoD Secret averaged $107,439, DoD Top Secret $126,839, and DoD TS/SCI $139,261. Work supporting an intelligence agency like CIA, FBI, or NSA averaged $165,063. The survey said it plainly. The gap between a Secret clearance and intelligence agency work is nearly $60,000 a year.
My read. In my experience in this market, AWS has paid around $45,000 extra for cleared roles with a poly. Microsoft has paid around 25% more for TS/SCI with a polygraph. Those are my own observations, not published rates. The cleared premium is open to negotiation, and the polygraph is the piece with the most room. Ask about the cleared pay bump every time you talk money.
Full scope is where the most money is. It is also where the fewest agencies are.
Plan on a few hours in one session. Some people get called back for a second session, and that's normal, not a bad sign.
The topics are published. The IC lists them:
Nothing on that list should be a surprise by the time you sit down.
The exam isn't reading your mind. It records physical responses while you answer specific questions. If the examiner starts asking follow-ups, it's because your body reacted and they want to know why. A strong response doesn't decide anything on its own, and often it just points to a subject that needs a few more minutes of conversation.
Inconclusive isn't a rejection. It usually means another session, and plenty of people pass the second one without trouble. How many attempts you get depends on the contract. Some set a limit, so ask your security officer if that matters in your case.
My tips, and they're short on purpose:
And the one people need most. Nerves don't fail polygraphs. Examiners expect anxious people, because almost everyone who walks in is one, and the exam isn't scoring how nervous you feel.
People chase them for three reasons, and all three are good ones. The pay, which the numbers above cover. The work itself, which you can't see from the outside, because some roles live behind secure networks only cleared people can reach. And the Intelligence Community as a career, if that's where you want to work.
One rule I give people. Once you hold a polygraph, it's a career asset, so use it as one.
One practical note on timing. A polygraph adds calendar time to a process that's already long, and IC timelines are the longest of any route into cleared work. Plan around that instead of being surprised by it. How long a security clearance takes has the rest of the schedule.
If the polygraph is what brought you here, it's rarely the obstacle people expect. Getting sponsored is. The roles on my results page include ones that required a Top Secret with a polygraph.
