What is TS/SCI? Top Secret eligibility, SCI access, and job requirements

TS/SCI is common job-posting shorthand, but it does not name a fourth clearance level above Top Secret. It combines a Top Secret requirement with eligibility or access for Sensitive Compartmented Information. The actual record, position, information owner, need-to-know, and any additional program conditions still matter.

Reviewed July 13, 2026. Definitions come from current National Archives, DCSA, and ODNI sources; Colorado job counts update from approved direct-employer listings.

The short answer

TS means Top Secret, the highest of the three classification levels. SCI means Sensitive Compartmented Information, which DCSA describes as information requiring special controls inside formally established intelligence compartments. A person can retain collateral Top Secret eligibility even when SCI eligibility is separately denied or revoked, so “Top Secret” and “TS/SCI” are not interchangeable status claims.

These counts come only from current eligible direct-employer postings that explicitly state TS/SCI. They describe job requirements, not the status of any applicant.

Current openings

461

Explicitly require TS/SCI at a named Colorado workplace.

Hiring employers

14

Direct employers with at least one current matching posting.

Active required

295

State that the requirement must already be active.

May be obtainable

166

Explicitly allow obtainable timing without promising sponsorship or eligibility.

64 current TS/SCI postings also explicitly name a CI or full-scope polygraph. TS/SCI alone is not evidence that a polygraph is required.

Decode TS/SCI one part at a time

Top Secret classification

Executive Order 13526 reserves Top Secret for information whose unauthorized disclosure could reasonably cause exceptionally grave damage to national security.

Top Secret eligibility

A competent authority determines whether a person is eligible for access at the required level. Eligibility by itself does not authorize access to every Top Secret record.

SCI eligibility and access

SCI uses formal access-control systems for intelligence sources, methods, or analytic processes. The responsible organization must approve the person under the applicable SCI standards.

Position and need-to-know

The job must require the information, and an authorized holder must determine that the person needs the specific information for an authorized government function.

Is TS/SCI the highest security clearance?

Top Secret is the highest classification level. SCI is not a rung above it; it is specially controlled intelligence that adds its own eligibility, access, and handling requirements. Job sites often display “TS/SCI” beside Secret and Top Secret because candidates need a practical filter, but that presentation should not turn SCI into a fourth classification level.

Special Access Programs are another distinct controlled-access concept. A TS/SCI record does not automatically grant SAP access, and SAP wording in a posting should be confirmed with the employer's authorized security office.

What does “read into SCI” mean?

Hiring shorthand can compress several steps. A favorable Top Secret or SCI eligibility record does not mean a person may enter every compartment. The responsible organization still controls assignment, verifies the record, determines need-to-know, grants the relevant access, and provides the required security briefing or indoctrination before access begins.

That is also why prior SCI access should not be presented as proof of current access at a new employer. The receiving security office evaluates the authoritative record and the new position's exact requirements.

Does TS/SCI always require a polygraph?

No universal rule makes every TS/SCI position a polygraph position. ODNI's SCI personnel-security directive says Intelligence Community elements with polygraph programs may require examinations when the head of the element considers one necessary in the national-security interest. DCSA separately lists polygraphs among possible special requirements for SCI or other controlled programs.

Read the employer source for an explicit CI, full-scope, expanded-scope, or other examination requirement. Cleared Colorado records CI and full-scope labels separately and does not infer either one from TS/SCI, the employer, the workplace, or the job title.

What is a SCIF?

A Sensitive Compartmented Information Facility is an accredited physical area where SCI may be processed, stored, used, or discussed. It is a facility standard, not a personnel clearance. A posting can therefore name TS/SCI, a SCIF worksite, onsite attendance, and a polygraph as separate facts.

Do not assume that every TS/SCI role is fully onsite or that “hybrid” permits classified work at home. The employer source and security procedures control where each duty can be performed.

How do you get TS/SCI for a job?

  1. A position creates the requirement

    An individual cannot initiate TS or SCI processing independently. The employing organization identifies a job-based need.

  2. The sponsor starts personnel vetting

    The authorized organization initiates the appropriate process and gives the applicant secure instructions for the required forms and records.

  3. The government makes eligibility determinations

    Investigative and adjudicative authorities apply the governing standards. Employment, interim action, final eligibility, and access are separate decisions.

  4. The responsible organization grants specific access

    After verifying eligibility, the information owner or authorized component applies need-to-know, program conditions, briefings, and any separately required polygraph.

Never pay a person who claims they can sell, transfer, or independently issue TS/SCI. Verify the employer, recruiter, and application domain before providing personal information.

How to read TS/SCI wording in a job posting

Required status

Does the employer require current TS/SCI, state that it must be active, or explicitly say the requirement may be obtainable?

SCI wording

Does the posting require SCI eligibility, current access, the ability to obtain SCI, or work supporting a program? Do not treat those phrases as identical.

Polygraph

Look for a separately stated CI, full-scope, expanded-scope, or agency-specific requirement and confirm its currency rules.

Workplace

Check the named Colorado workplace and work setting. SCIF duties and unclassified duties may have different location constraints.

Additional programs

SCI, SAP, special-program, caveat, and customer-specific access can create different approval paths beyond collateral Top Secret.

Verification

Use the employer security office—not a résumé, badge, screenshot, or public lookup—to verify how the authoritative record maps to the position.
