Frequently Asked Questions and Common Misperceptions
ResearchPublished Jun 17, 2026
There is often confusion about how personnel vetting works. Policies and procedures evolve, and details can be misunderstood or misinterpreted. This reference sheet is designed to clarify the personnel vetting process as of 2026 and address common misperceptions about the process. The information is organized as follows:
Each section answers frequently asked questions to help applicants, employees, and clearance holders understand the rationale behind the process, what adjudicators consider, and how to navigate the process responsibly and confidently.
This reference sheet addresses frequently asked questions and common misperceptions about the personnel vetting process. It was developed by RAND researchers for the U.S. government (USG) and reported in Insights and Tools to Improve the Applicant Experience in the Personnel Vetting and Security Clearance Process.[1] If you have additional questions regarding personnel vetting, security clearances, or your specific case, contact your organization’s security office for guidance.
In no way should the information contained in this document be substituted for the U.S. National Security Adjudicative Guidelines or U.S. government laws and policies, nor should this document be considered any form of legal advice.
Personnel vetting is defined by the U.S. Office of Personnel Management (OPM) as “the process the government uses to make sure people working for or on behalf of the government can be trusted to protect our nation’s people, property, information, and critical missions, both when they’re hired and throughout their federal service.”[2] Specifically, it is the process used by USG agencies to determine whether someone is (1) suitable or fit for employment, (2) eligible for a position of public trust, and (3) eligible for a security clearance or to hold a sensitive position.
No, all USG employees, contractors, and members of the armed forces go through personnel vetting. Because some employers informally refer to personnel vetting as a fitness check or background check or use another unofficial term, people sometimes go through personnel vetting without realizing that is what the process is officially called.
Personnel vetting is used by USG agencies for
When hiring employees or contractors, USG agencies evaluate applicants’ character, conduct, and reliability to ensure that they meet the standards required to work for or on behalf of the federal government.
In both cases, agencies evaluate whether a person’s character and conduct meet the standards required to work in federal or contractor positions. Although some USG agencies use the term suitability to describe their vetting processes for these roles, such decisions for noncompetitive service, excepted service, and contractor personnel are fitness determinations.
A suitability determination or a fitness determination assesses whether a person’s character and conduct support the integrity, efficiency, and effectiveness of government service. Such a determination is required for all USG competitive service employees (suitability) and excepted service and noncompetitive service employees, contractors, and military personnel (fitness).
A security clearance, on the other hand, determines whether a person can be trusted in a national security position with access to classified information.
Although both processes evaluate trustworthiness, suitability determinations and fitness determinations focus on whether someone is appropriate for employment working in or on behalf of the federal government, and a clearance focuses on protecting national security information.
A position designated as public trust is one in which an individual’s actions can affect how effectively and efficiently the USG operates and maintains the public’s confidence. These positions do not require access to classified information, but they do carry a level of responsibility in which poor judgment or misconduct could negatively affect government operations or public confidence. To serve in a designated public trust position, personnel vetting standards require that USG hiring agencies decide whether the individual is eligible for a public trust position as part of their suitability or fitness determination.
A security clearance allows an individual to access classified national security information. You only need a security clearance if your job requires such access. To qualify, you must be a U.S. citizen and you must be sponsored by a government agency because the position you are filling requires classified access.
A security clearance investigation reviews your loyalty, character, trustworthiness, and reliability to ensure that you can be trusted with national security information. After the vetting process, your sponsoring agency reviews the results and decides whether to grant you security clearance eligibility.
Security clearance eligibility means that, based on information collected as part of your background investigation, an adjudicator determines that you meet the standards to hold a security clearance. However, eligibility alone does not guarantee that you will receive a security clearance or that you will have access to classified information.
You can receive a security clearance—and then have access to classified information—when
Depending on the level of vetting required for a position, there are up to six major steps in the personnel vetting process:
Each step is described in more detail in Personnel Vetting 101 Applicant Toolkit, Annex I: The Personnel Vetting Process. For some steps, the applicant needs to take action; for others, personnel vetting or agency staff take action.
No. There are USG-wide requirements that depend on the type of position or clearance being sought. Some steps in the process, such as completing a vetting questionnaire, are required of everyone, but other steps, such as fingerprinting, are not. So, for example, being vetted for suitability requires fewer steps than being vetted for eligibility for a security clearance. Some agencies have additional requirements for certain positions, such as completing a polygraph, medical examination, or psychological evaluation.
The vetting questionnaire is a key part of the vetting process. It collects information about your background so investigators and adjudicators can determine your suitability or eligibility for a clearance or sensitive position.
No. Answer every question to the best of your ability; do not submit the questionnaire with unanswered questions. If you are unsure how to respond, contact your employer’s security office or another official source. When information is truly unknown or cannot be obtained, state that clearly in your answer and include a brief explanation wherever the form provides a space to do so.
No. You should answer every question completely and truthfully. Omitting or mispresenting information is considered a serious breach of trust and can lead to denial or revocation of your suitability or security clearance eligibility. If you have unusual circumstances or mitigating factors that the form does not fully capture, use the comment sections to provide context. For those applying for public trust or security clearance eligibility, the Personnel Vetting 101 Applicant Toolkit, Annex III: Security Clearance Guidelines in Brief includes a summary of mitigating conditions adjudicators may consider when evaluating potential security concerns.
No. The questionnaire asks for specific information that helps determine your overall trustworthiness and not just what relates to your job duties. Answer all the questions as written, even if something seems unrelated or minor.
The government expects applicants to use their own words when completing the questionnaire. If you are unsure how to answer a question, contact your employer’s security office or the sponsoring agency for guidance rather than relying on artificial intelligence or automated tools.
If you are completing the form online, you can usually save your progress and return to it later. Check the instructions provided to you or ask your employer’s security office or the sponsoring agency for details.
If you experience issues accessing, navigating, saving, or submitting the form, reach out to your employer’s security office first. They can help resolve the problem or direct you to the appropriate information technology support. If the Defense Counterintelligence and Security Agency (DCSA) is handling your case, you can contact the DCSA Applicant Knowledge Center support line at (878) 274-5091.
A background investigation is a review of your history and conduct to help determine whether you are suitable or fit to work for or on behalf of the federal government and/or whether you are eligible to hold a position of public trust or national security. Investigators collect information from a variety of sources—such as your questionnaire, interviews, and records—to verify your honesty, reliability, and overall suitability. The goal is not to find faults but to build a complete and accurate picture of your background.
No. Investigators follow established federal investigative standards that outline the information they must gather and the types of sources they can use. Their goal is to verify the information you provide in the vetting questionnaire and get a complete picture of you as a whole person. If there are concerns raised in the background investigation, they will document those concerns, as well as any mitigating factors, for the adjudicator to consider in their determination of whether you are eligible to hold a position of trust.
If an interview is required, your investigator will work with you to find a time and place that fits your schedule. Interviews may be conducted in person or virtually. For in-person meetings, the investigator may suggest your workplace or another private location. Delays in having the interview can slow the vetting process, so it is best to respond promptly when contacted to arrange your interview.
The length of the interview depends on several factors, including the type of background investigation and the information that needs to be discussed. When scheduling, you can ask your investigator how long they expect it to take.
Yes. Investigators can grant reasonable requests. For example, when scheduling, you may ask for a language interpreter, an investigator of a different gender (e.g., for religious reasons, personal comfort, or other reasons), or a location that is private and accessible. During an interview, you can also request breaks or ask to move to a quieter or more comfortable setting, if needed.
The interview is not something you pass or fail, and investigators do not make adjudicative decisions. Their role is to collect and provide information to the adjudicators who will review all materials and make the final determination about your suitability or clearance eligibility.
After completing the interview, the investigator adds the information they gathered to your case file and submits it to the adjudicator. The investigator may contact you again if additional details are needed. Once the investigation is complete, you will wait for the adjudicators at your sponsoring agency to make an eligibility determination. If you have questions or want to check on your case status, contact your employer’s security office or the sponsoring agency. If DCSA is conducting your investigation, you can also reach out to the DCSA Applicant Knowledge Center support line at (878) 274-5091.
Polygraph examinations are not part of most agency vetting or security clearance processes. However, certain intelligence and law enforcement agencies may require a polygraph—and potentially a medical and/or psychological evaluation—as part of their vetting assessments for specific positions. If you are asked to take a polygraph, focus on being truthful and answering questions directly rather than trying to “pass.”
Federal regulations (5 CFR 731) list the following factors agencies must consider when making suitability determinations.[3] These factors are also applied to fitness determinations. These include
Agencies may also consider mitigating factors listed in 5 CFR 731, such as
There are USG-wide standards that apply to all federal employees and contractors. In addition, each agency may establish supplementary requirements based on its mission and the sensitivity of its positions. The final suitability determination or fitness determination is made by an adjudicator with the hiring agency, who applies both the government-wide standards and any agency-specific criteria. Because agencies have different missions and risk profiles, individuals with similar backgrounds may receive different determinations from different agencies.
No. The process follows USG-wide standards that are designed to ensure fairness and consistency. Security clearance decisions are based on the publicly available U.S. National Security Adjudicative Guidelines outlined in Security Executive Agent Directive 4 (SEAD 4).[4] The guidelines define the information and mitigating factors adjudicators must consider when they evaluate an individual’s loyalty, reliability, and trustworthiness.
There are government-wide standards for determining eligibility to hold a national security position and/or a security clearance, which apply uniformly across all USG agencies. These standards are established in SEAD 4. The Personnel Vetting 101 Applicant Toolkit, Annex III: Security Clearance Guidelines in Brief summarizes the key factors adjudicators consider when evaluating eligibility for a national security position and a security clearance.
In addition to the USG standards, each sponsoring agency may have supplemental requirements based on its mission and the sensitivity of its positions. For example, some agencies may require a polygraph, medical examination, psychological evaluation, or other assessments as part of their specific vetting processes.
The final eligibility determination is made by an adjudicator within the sponsoring agency, who applies the USG-wide SEAD 4 guidelines plus any agency-specific requirements.
Under SEAD 4, adjudicators review all information related to an individual’s loyalty, character, honesty, judgment, reliability, discretion, and overall trustworthiness. SEAD 4 outlines 13 specific guidelines that adjudicators must consider, and each guideline is accompanied by a description of the concern, circumstances that may cause security concerns, and conditions that may mitigate those concerns. The guidelines are as follows:
Each SEAD 4 guideline includes examples of behaviors or circumstances that could raise concerns, such as
Adjudicators evaluate past conduct using the whole person concept, which means they consider all reliable information—both positive and negative—about an individual’s life to make a balanced determination. Rather than focusing on a single event, adjudicators look at patterns of behavior, context, and evidence of change over time to assess whether someone can be trusted with national security information.
In general, adjudicators consider factors such as
For each SEAD 4 guideline, there are specific factors adjudicators can consider that may lessen or resolve concerns, such as
With very few exceptions, which are outlined in the SEAD 4,[5] potentially negative events in your past are not automatic disqualifiers. Adjudicators apply the whole person concept, meaning they evaluate your entire personal history and not just isolated incidents. They consider context, recency, seriousness, and evidence of rehabilitation or positive change before making a determination about your eligibility.
During the first few steps of the vetting process, it is usually clear where you are. If you are unsure, ask your employer’s security office or the agency that requested you undergo the personnel vetting process (your sponsoring agency).
Each step has different requirements and deadlines. Official communications from your employer or sponsor will include the deadline for completing the vetting questionnaire and other actions. If you receive an unfavorable adjudicative decision and want to appeal, reach out to your employer’s security office or sponsoring agency to inquire about the appeals process, including any deadlines or time limits.
Yes. Contact your employer’s security office, the sponsoring agency, or your investigator. They will try to work with you, although deadlines cannot be extended indefinitely.
If you need any accommodations or adjustments, let your investigator, your security office, or the sponsoring agency know as early as possible. Making requests early helps ensure that they can be arranged in time—for interviews, that typically means mentioning any requests when scheduling. For example, you may ask for a language interpreter, an investigator of a different gender (e.g., for religious reasons, personal comfort, or other reasons), or a location that is accessible. During the interview, you can also ask for short breaks or a change of location if the setting is uncomfortable or distracting.
Processing times vary. Low-risk positions may take a month or two; security clearances can take several months or longer. Delays are common and do not necessarily indicate a problem with your application.
Yes. You can help avoid delays by
Keep in mind that some factors that may affect processing time—such as the complexity of your background, investigator workload, and case processing backlogs—are outside your control.
These factors help adjudicators evaluate issues related to an applicant’s allegiance to the United States, foreign influence, and foreign preference under SEAD 4. The goal is to determine whether any foreign relationships or activities could create divided loyalties or make an individual vulnerable to manipulation or coercion by a foreign government or entity. Accurate reporting of all foreign ties and travel is needed for a fair and complete assessment.
The foreign contacts section of the vetting questionnaire is intended to identify any non-U.S. citizens with whom you have relationships, so that potential national security risks can be evaluated. When deciding who to list, review the questionnaire’s instructions closely and consider how they apply to foreign family members and contacts. Some key questions to evaluate include the following:
If you do not have all the requested details about a foreign contact, include whatever information you can and use the comment section to describe the relationship and provide helpful context. This gives the investigator a clearer picture and may speed up the review process. In most cases, you should not reach out to the person to obtain the missing information. If you are unsure, contact your employer’s security office or the sponsoring agency.
No. There is no country blacklist. Each case is evaluated individually and in context using the whole person concept.
No. However, substantial business, financial, or property interests in a foreign country or in any foreign-owned or foreign-operated business may raise concerns if those interests could expose you to foreign influence, exploitation, or a personal conflict of interest. Adjudicators review these connections under SEAD 4, Guideline B (Foreign Influence), and consider such mitigating factors as the nature of the interest, the country involved, and your ability to exercise independent judgment.
No. SEAD 4 explicitly states that being a dual citizen is not disqualifying for obtaining a security clearance, regardless of the country or countries involved. However, your sponsoring agency may have additional standards or requirements based on its mission and the sensitivity of its positions. Agencies may consider the USG’s relationship with the country, your connections there, and any specific risks relevant to their work. For more information, see SEAD 4, Guideline C (Foreign Preference).
No. The SEAD 4 guidelines do not require dual citizens to renounce foreign citizenship or destroy or surrender foreign passports. Before 2017, some departments and agencies, including the U.S. Department of War, had such requirements, but they are no longer part of the government-wide standards. That said, a willingness to renounce foreign citizenship can be considered a mitigating factor if foreign preference concerns arise. For more information, see SEAD 4, Guideline C (Foreign Preference).
For additional answers to common vetting questions related to dual citizenship, see Addressing Common Questions and Concerns from Dual or Naturalized Citizens Regarding the Security Clearance Process.[6]
Yes. Even if marijuana use is legal under your state’s law, it remains illegal under federal law, and federal laws govern all security clearance decisions. You must report the use of any illegal drugs or controlled substances, including marijuana, on your vetting questionnaire. Federal agencies evaluate this information under SEAD 4, Guideline H (Drug Involvement And Substance Misuse), and Appendix B (Bond Amendment). Failing to disclose drug use can raise more serious concerns than the use itself because honesty and integrity are central to clearance eligibility.
Use of cannabidiol (CBD) and medical marijuana products can also pose risks when it comes to getting a security clearance. Many CBD products are not federally regulated and may contain tetrahydrocannabinol (THC), which could appear on a drug test and be disqualifying. Even if medical marijuana is prescribed under state law, its use is still illegal under federal law and must be disclosed. If you have used these products, report them accurately and provide context in your questionnaire. Transparency helps adjudicators evaluate your case fairly.
Not necessarily. Adjudicators apply the whole person concept when reviewing past drug use. They consider such factors as
Yes, current or ongoing use of illegal drugs, including marijuana, is generally incompatible with holding a security clearance. The adjudicative guidelines emphasize a person’s willingness to comply with the law, and using a schedule 1 controlled substance under federal law conflicts with those standards. However, if you have stopped using, acknowledged the issue, and demonstrated that you do not intend to use again, you may still be eligible to hold a security clearance. Some agencies may require a longer period of abstinence before granting or reinstating a clearance, especially for higher-level positions.
No. Failure to be truthful is a significant concern. Honesty and integrity are among the most important traits evaluated in the clearance process. You should report any illegal drug use on your vetting questionnaire, as required. There is space to provide context—such as limited use or unique circumstances—which helps adjudicators understand your situation. You may also be asked about drug use during your security interview. Be honest and forthright; investigators are trained to identify discrepancies and credibility matters.
No. Seeking mental health treatment does not harm your clearance eligibility. In fact, it demonstrates responsibility, good judgment, and self-awareness—qualities that are viewed positively in the clearance process. Ignoring or hiding problems can raise more concern than addressing them. The government encourages individuals to seek appropriate care when needed and does not penalize those who do.
No. Mental health conditions are not automatically disqualifying. Emotional, mental, and personality conditions only raise concerns if they cast doubt on judgment, stability, reliability, or trustworthiness. For more information, see SEAD 4, Guideline I (Psychological Conditions).
No. Investigators do not have unrestricted access to your medical records. If mental health information is relevant, investigators may request limited verification from a provider—typically confirmation that you are stable, reliable, and not a security risk. Only information that is necessary to make a security clearance determination is considered; there are rules in place to protect privacy.
No. An arrest or conviction does not automatically disqualify you from government employment or a security clearance. Adjudicators review each case using the whole person concept. They consider such factors as the nature of the offense, how long ago it occurred, the circumstances, and evidence of rehabilitation or positive change. Honesty about your history is important—failure to disclose required information can raise concerns about your trustworthiness that may be more serious than the offense itself.
Possibly. Being charged with a crime does not automatically prevent you from obtaining a security clearance. Adjudicators consider the circumstances surrounding the charge and whether the underlying conduct raises concerns about judgment, reliability, and trustworthiness and any information that demonstrates your current reliability and good judgment.
It depends. Appendix B of SEAD 4 states that individuals may be automatically disqualified if they are convicted of a crime in a U.S. court, although waivers are available under some conditions. However, any criminal history that raises questions about an individual’s judgment, stability, reliability, or trustworthiness may be a concern. For more information about how criminal activity may raise concerns—and how those concerns can be mitigated—see SEAD 4, Guideline J (Criminal Conduct), and Appendix B (Bond Amendment).
Possibly. The vetting questionnaire requires you to report certain types of arrests, charges, or citations, even if they were later dismissed or expunged. Read the questions in this section carefully to determine what you need to report.
Financial hardship can make individuals more susceptible to outside influence or risky decisions. Adjudicators review financial history to assess whether an applicant manages obligations responsibly and can be trusted to act with integrity under pressure. If you have debt, the focus is on behavior and recovery and not on the presence of debt itself.
No. Debt or bankruptcy alone do not automatically disqualify you. Financial issues are evaluated under SEAD 4, Guideline F (Financial Considerations). The government’s concern is not whether someone has ever had debt or struggled financially but whether unresolved debt or poor financial management could reflect questionable judgment or create vulnerability to pressure, coercion, or exploitation. Adjudicators look for responsibility, honesty, and stability and not perfect credit. They consider such factors as the reasons for the debt, how you handled it, and whether the situation is under control.
No. A single overdue account or unexpected expense that ends up in collections is unlikely to be disqualifying on its own. Concerns arise when there is a pattern of unresolved debt, ignored creditor contact, or no effort to address the problem. Current or ongoing financial distress is more concerning than older issues that have been resolved.
Yes. Adjudicators consider the circumstances that led to the financial issues. Student loans, mortgages, and other long-term debts that are being paid as agreed and responsibly managed are not generally viewed as security risks. Debt resulting from uncontrollable events—such as job loss, medical emergencies, or family hardship—can often be mitigated if you have taken steps to recover. Debt that stems from reckless spending, gambling, or ongoing mismanagement may raise greater concerns. However, using the whole person concept, adjudicators will consider the actions you have taken to address the problem, such as changing your financial habits, seeking financial counseling, and regaining control of your finances.
Possibly. Your spouse’s or partner’s conduct can influence your clearance if it raises concerns about judgment, reliability, or vulnerability to coercion:
Adjudicators apply the whole person concept when making eligibility determinations, and they consider both context and mitigating factors. Showing that you act responsibly, address issues within your control, and take reasonable steps to separate yourself from problematic behavior or circumstances can help mitigate concerns.
Your information may be seen by your organization’s security office and the investigator and adjudicator for your case. The USG uses strong privacy and security protocols to protect personal data.
Yes. During personnel vetting, you are enrolled in continuous vetting. That means while you remain a government employee, contractor, or member of the armed services, the USG will regularly conduct record checks, and you must meet ongoing reporting requirements. Also, if there are changes to your position or responsibilities within an agency or you change agencies, additional vetting may be required.
If anyone advises you to omit required information, avoid mental health treatment, hide foreign contacts, or destroy documents, that guidance is incorrect, and following it could harm your case. If you receive bad advice, disregard it—providing complete and honest information is always the right approach. If you already submitted incorrect or incomplete information,
Adjudicators assess your honesty, trustworthiness, and overall character. Correcting misinformation and being open about mistakes demonstrates good judgment and reinforces your reliability.
