Security clearance background-check guide
How far back does a security clearance background check go?
There is no single “7-year background check” or “10-year background check” rule for a security clearance. The current SF-86 mixes question-specific 7-year and 10-year periods with questions that ask whether something has ever happened. The investigation itself depends on the position and can include verification and follow-up beyond simply reading the form.
Reviewed July 13, 2026. Form details come from the current public OPM SF-86 and DCSA applicant guidance; job counts update from approved direct-employer listings.
The short answer
Prepare at least 10 years of address, school, and work history, but answer every SF-86 question using its own wording. Some sections use seven years, some use 10 years, some require older degrees or a minimum amount of history, and some say “ever.” Do not choose a timeframe based only on whether a job says Secret or Top Secret.
Three clocks people often confuse
The form's reporting period
The investigation's coverage
Ongoing vetting
What commonly goes back 10 years on the SF-86?
| History | Current form instruction | Important exception |
|---|---|---|
| Residences | Account for the last 10 years without breaks. | Do not list a residence before age 18 unless needed to provide at least two years of residence history. |
| Employment | List employment, unemployment, and self-employment from the present back 10 years without breaks. | Do not list employment before age 18 unless needed to provide two years of history. |
| Education | Report schools attended in the last 10 years. | The form separately asks about a degree or diploma received more than 10 years ago. |
| Civil court actions | Section 28 asks about covered public-record civil court actions in the last 10 years. | Use the section's definition and do not substitute criminal or financial-section instructions. |
DCSA summarizes the preparation rule this way: most sections require information going back 10 years, but applicants must read every question because different instructions control. The age-18 rule is not permission to leave a gap when the form requires a minimum two-year history.

Examples on the current form include foreign contacts and foreign travel, many police-record questions, illegal drug use, numerous financial events, and unauthorized information-technology activity. Those examples do not create one seven-year rule for the entire questionnaire.
Foreign travel
Police record
Drug activity
Financial record
“Ever” means the shorter window does not control that question
The SF-86 includes lifetime questions. Section 22, for example, separately asks whether an applicant has ever been charged with a felony, a firearms or explosives offense, or an alcohol- or drug-related offense. Other sections also contain “ever” branches. An event does not disappear from an “ever” question merely because it happened more than seven or 10 years ago.
Does the form's lookback limit what investigators can ask?
Do not treat a form date range as a promise that every other fact is invisible. DCSA says the extent of an investigation depends on the type of job and the harm the position could cause. During an investigation, it may search law-enforcement, court, employment, education, creditor, and other record sources; contact people who know the applicant; and interview the applicant to verify, expand upon, or clarify questionnaire information.
That does not mean an applicant should invent a broader disclosure rule. Answer the current form exactly, respond truthfully to authorized follow-up, and ask the sponsoring security or HR office when an instruction is unclear. Cleared Colorado cannot decide whether an individual fact is reportable.

The SF-86 is the questionnaire for national security positions; its question wording does not turn into a simple “Secret checks seven years, Top Secret checks 10” formula. The sponsoring agency designates the position and appropriate investigation. Access level, investigation coverage, form reporting periods, adjudication, and program-specific requirements are related but distinct.
Compare clearance levels, SCI, and need-to-know →Public Trust is not the same background-check question
This page addresses the SF-86 used for national security positions. A Public Trust position is not a security clearance and may use a different personnel-vetting questionnaire and investigation based on the position's risk and sensitivity. Do not carry SF-86 timeframes into an SF-85P or a private commercial background check.

Build a private 10-year timeline
Collect addresses, schools, work locations, employers, unemployment, supervisors, travel, and other records before opening eApp.
Read the instruction above each question
Use its seven-year, 10-year, current, age-based, minimum-history, or ever wording—not a rule remembered from another section.
Check for gaps and branch questions
Make sure continuous-history sections are complete and review every follow-up opened by a yes answer.
Use estimates honestly
The form allows estimated dates where identified. Do not manufacture exact dates or omit an answer simply because a record is difficult to find.
Protect the working record
Keep SF-86 data in a secure location and submit only through the sponsor's authorized system. Never send it to a job board or unverified recruiter.
Current Colorado jobs that allow obtainable clearance timing
Cleared Colorado currently has 518 direct-employer listings across 14 employerswhose source language explicitly allows the required clearance to be obtainable. This filter says nothing about an investigation's lookback, sponsorship terms, eligibility, interim access, or the employer's final hiring decision.

Search the job language, not a rumored lookback rule
Monitor Colorado postings that explicitly allow obtainable clearance timing. The sponsor and government process determine the investigation; Cleared Colorado never collects SF-86 answers or vetting records.
