Security Clearance Levels Explained
In the U.S., security clearances come in three main levels, each granting access to different types of classified information. Knowing these levels can help you navigate the application process and understand which roles you may qualify for.
The primary distinction between clearance levels lies in the sensitivity of the information and the potential harm its exposure could cause to national security. Higher clearances involve more thorough investigations, stricter reinvestigation schedules, and access to highly specialized roles.
| Clearance Level | Reinvestigation Period | Average Processing Time | Typical Access |
|---|---|---|---|
| Confidential | Every 15 years [2] | Varies by tier | Information that could damage national security if disclosed |
| Secret | Every 10 years [2][4] | 73 days (investigation phase) | Information that could cause serious damage to national security if disclosed |
| Top Secret | Every 5-6 years [2][4] | 215 days (investigation phase) | Information that could cause exceptionally grave damage to national security if disclosed |
All clearance holders are monitored under Continuous Evaluation (CE), which uses automated checks to flag issues like arrests, financial problems, foreign travel, or unusual transactions between scheduled reinvestigations [2].
Below is a closer look at each clearance level.
Confidential Clearance
Confidential clearance is the most basic level and grants access to information that could harm national security if disclosed. The investigation process is relatively straightforward, making it the least demanding clearance to obtain. Reinvestigation is required every 15 years [2].
Jobs requiring Confidential clearance include administrative support roles in defense agencies, technical positions with government contractors, and entry-level military intelligence roles. These positions often involve handling classified documents or attending meetings with restricted information.
Secret Clearance
Secret clearance, the mid-level tier, permits access to information that could seriously harm national security if disclosed. The investigation for this clearance is more thorough than for Confidential clearance, covering references, financial history, foreign contacts, and travel records. For cases completed through April 2025, the timeline averages 18 days to initiate, 73 days for investigation, and 47 days for adjudication [5].
Roles requiring Secret clearance include intelligence analysts, cybersecurity specialists working with classified systems, defense contractors developing sensitive technologies, and specialized military personnel. Reinvestigation is required every 10 years [2][4].
Top Secret Clearance
Top Secret clearance is the highest level, reserved for access to information that could cause exceptionally grave harm to national security if disclosed. The investigation process is the most rigorous, involving an in-depth review of financial records, foreign connections, travel habits, and personal conduct. On average, the investigation phase takes 215 days [5].
Positions requiring Top Secret clearance include senior intelligence officers, special operations forces, high-level policy advisors, and contractors involved in the most sensitive defense projects. Reinvestigation is now required every 6 years [2][4], a change aimed at improving national security by allowing for quicker vetting and better oversight of personnel behavior [3].
A security clearance stays active for up to 24 months after leaving a cleared position. After that, a new investigation is needed to regain access. However, Continuous Evaluation continues during this period to monitor for issues like significant debt, criminal charges, or foreign marriages, which could trigger earlier reviews [2][4].
How to Apply for a Security Clearance
Applying for a security clearance isn’t something you can tackle on your own – it requires sponsorship from an employer and involves several structured steps. Knowing what to expect can help you navigate the process more smoothly.
Sponsorship and Eligibility Requirements
To start, you’ll need sponsorship from a federal agency or an approved contractor. Typically, this happens after you’ve received a conditional job offer for a position that requires a security clearance.
Once you’re on board, your employer or a designated clearance coordinator will guide you through the initial steps and provide access to the application system.
Completing the SF-86 Form
The SF-86, or Questionnaire for National Security Positions, is a detailed document that plays a key role in the clearance process. This form, which runs over 100 pages, is usually completed online through the Electronic Questionnaires for Investigations Processing (e-QIP) system [7][2]. It’s required for roles involving Tier 3 and Tier 5 background investigations [6].
After your sponsorship is confirmed, your employer will grant you access to e-QIP and help you get started. The SF-86 demands an extensive amount of personal information, including:
- Employment history
- Education details
- Past residences
- Foreign contacts and travel
- Financial records
- Criminal history
- Personal references
The depth of information required depends on the clearance level you’re pursuing. To avoid delays, gather necessary documents – like old addresses, references, travel itineraries, credit reports, and academic transcripts – before starting. This preparation might take several days or even weeks.
Accuracy is critical here. Mistakes, omissions, or inconsistencies are the leading causes of delays and even denials [8]. Complete honesty is essential. As the National Security Law Firm emphasizes:
"Omitting a past incident (e.g. drug experimentation or an old arrest) is viewed the same as lying – and both can destroy your chances. In fact, providing false information on a security clearance form is a federal crime that can lead to fines or imprisonment." [7]
Set aside about 4–6 hours to carefully fill out and review the form. Double-check every detail for accuracy [2]. Once submitted, your security team will review the form, and they might reach out for clarification or additional details [1]. After this review, the process transitions into the background investigation phase.
Background Investigation and Adjudication
Following the submission of your SF-86, investigators will verify and expand on the information you’ve provided. They may contact you directly, as well as your listed references, to gather additional insights [7]. Once the investigation is complete, the findings are reviewed to determine whether you’re eligible for a security clearance.

Career Advantages of Security Clearances
Holding a security clearance can open doors to a range of career opportunities, particularly in the defense and intelligence sectors. Beyond the rigorous process required to obtain one, a clearance can significantly shape your professional trajectory.
Access to High-Demand Jobs
Having a security clearance gives you access to roles that are both specialized and in high demand. Federal agencies like the Department of Defense, National Security Agency, Central Intelligence Agency, and Department of Homeland Security rely heavily on cleared professionals to carry out their missions. Likewise, defense contractors actively recruit individuals with clearances to meet the requirements of government contracts.
The cybersecurity sector is especially keen on hiring cleared personnel. As cyber threats grow more sophisticated, organizations need experts who can handle classified networks and safeguard sensitive infrastructure. Because the pool of eligible candidates is relatively small, cleared professionals have a distinct advantage in securing these roles. This demand not only ensures job availability but also supports career growth and financial stability.
Higher Salaries for Cleared Professionals
Jobs requiring security clearances often come with higher pay. This compensation reflects the trust and reliability expected of cleared individuals, as well as the effort involved in obtaining and maintaining the clearance. Many cleared roles also include bonuses and additional incentives, providing a boost to overall earnings.
As you gain experience in cleared positions, your earning potential tends to grow more quickly compared to similar roles that don’t require a clearance. Contract and consulting opportunities for cleared professionals often offer competitive hourly rates, further enhancing the financial rewards.
Long-Term Career Advancement
An active security clearance can be a stepping stone to long-term career success. Maintaining your clearance over time helps you build a strong reputation within the cleared community, where trust and a proven track record are highly valued.
Leadership roles in the defense and intelligence sectors frequently require a security clearance. Whether your goal is to oversee classified projects as a program manager or to rise to executive positions within defense contracting firms, a clearance can be a key credential. Pairing clearance eligibility with specialized technical skills can also lead to sought-after roles like counterintelligence analyst, signals intelligence specialist, or classified systems architect – positions that often come with greater job security and responsibilities.
Careers in defense and intelligence are often more stable than those in other industries. Federal funding for national security priorities ensures a steady demand for cleared professionals, creating a resilient job market. Additionally, a clearance remains valuable even if you shift between government positions, contractor roles, or sensitive jobs in the private sector. This flexibility ensures that your skills and trustworthiness are recognized throughout your career.
The periodic evaluations and reinvestigations required to maintain a clearance not only confirm your eligibility but also highlight your reliability and dedication. These qualities can help you stand out for promotions and new opportunities, making an active clearance a powerful asset for long-term career growth.
Maintaining and Renewing Your Clearance
Keeping a security clearance in good standing involves ongoing monitoring, periodic reviews, and a commitment to meeting strict standards.
Continuous Evaluation Requirements
The Trusted Workforce 2.0 initiative has introduced a more proactive approach to monitoring clearance holders. Instead of relying solely on periodic reinvestigations, the Continuous Evaluation (CE) program actively reviews databases and records to identify potential security concerns in real time. This ensures that clearance holders maintain their trustworthiness over time. By addressing issues as they emerge, continuous vetting not only reduces backlogs but also enhances the overall efficiency of the process [9].
This system uses a risk-based approach, focusing resources on high-risk cases while streamlining low-risk ones. Clearance holders are evaluated against the 13 Adjudicative Criteria outlined in Security Executive Agent Directive 4 (SEAD 4). These criteria cover areas such as allegiance to the United States, foreign influence, financial responsibility, and personal conduct.
Reinvestigation Schedules
Even with continuous evaluation, periodic reinvestigations remain essential. Under Trusted Workforce 2.0, those holding Top Secret clearances now undergo reinvestigation every six years, a change from the previous five-year interval [2][4]. Additionally, Congress is considering extending clearance eligibility after separation from service or employment. For instance, the Senate Armed Services Committee’s fiscal 2026 defense authorization bill proposes extending this eligibility to up to five years for military members and Department of Defense employees [9].
When it’s time for a reinvestigation, you’ll need to update your paperwork to reflect any changes in your circumstances. This includes details about your employment, residence history, foreign contacts, and financial records. Staying prepared for these reviews is an integral part of maintaining your clearance.
How to Stay Eligible
Beyond formal reviews, your personal conduct plays a key role in keeping your clearance intact. Areas to prioritize include:
- Financial Responsibility: Avoid excessive debt, unpaid bills, or tax issues that could raise concerns.
- Legal Compliance: Address any legal matters promptly to demonstrate good judgment.
- Reporting Changes: Notify your security officer about significant life changes, such as foreign travel, foreign contacts, marriage, divorce, or financial challenges.
- Substance Use: Seek help for issues related to illegal drugs, prescription misuse, or alcohol problems instead of trying to hide them.
Maintaining your clearance is about consistently proving your reliability, trustworthiness, and loyalty. By managing your personal responsibilities and maintaining open communication with security officials, you can uphold your clearance and ensure a smooth career path.
