The Tier 3 Investigation Is Designated For The Following Positions

Understanding Tier 3 Investigations: Positions Requiring a Moderate Risk Public Trust Clearance

A Tier 3 investigation, formally known as a Moderate Risk Public Trust investigation, is a critical component of the U.S. federal government's personnel security program. It is a background check more rigorous than a Tier 1 (Low Risk Public Trust) but less extensive than a Tier 5 (Top Secret/Sensitive Compartmented Information) investigation. Its primary purpose is to assess an individual's trustworthiness, reliability, and loyalty for positions that involve access to sensitive, but not classified, government information and facilities. These positions are designated as having the potential to cause a moderate level of damage to the national security, the efficiency of government services, or the integrity of federal programs if filled by an untrustworthy person. Understanding which roles fall under this designation is essential for both hiring officials and prospective federal employees.

The Foundation: What Defines a "Public Trust" Position?

Before detailing the specific positions, it's crucial to understand the framework. Public Trust positions are not classified positions in the traditional sense (like Secret or Top Secret). Instead, they involve access to sensitive but unclassified (SBU) information. This includes law enforcement sensitive data, critical infrastructure details, certain financial records, proprietary government data, and information protected by statutes like the Privacy Act. The risk level—Low, Moderate, or High—is determined by the potential impact an individual's misconduct or negligence could have on the mission. A Moderate Risk designation means the position's duties could, if compromised, cause a serious adverse effect on agency operations or national interests.

Positions Designated for a Tier 3 (Moderate Risk) Investigation

The designation is tied to the position's sensitivity, not the agency. Therefore, similar roles across different federal departments and agencies may require a Tier 3. The following categories represent the most common types of positions requiring this level of scrutiny.

1. Law Enforcement, Security, and Protective Service Roles

This is a primary category for Tier 3 investigations. The inherent authority and access to sensitive operations necessitate a higher trust standard.

• Federal Law Enforcement Officers (non-Special Agent): Positions like U.S. Park Police officers, Federal Air Marshals (in certain non-tactical roles), and other uniformed officers who carry firearms and make arrests.
• Customs and Border Protection (CBP) Officers: These officers have direct authority to inspect, search, and detain individuals and goods at ports of entry, handling vast amounts of sensitive data.
• Federal Protective Service (FPS) Officers: Responsible for securing federal buildings and property.
• Security Specialists and Advisors: Individuals who develop, implement, and oversee physical security programs, access control systems, and security protocols for federal facilities.
• Detention and Transportation Officers: Roles within the Bureau of Prisons or U.S. Marshals Service involving the custody and movement of inmates.

2. Financial Management and Acquisition Positions

Positions with significant authority over government funds, contracts, or procurement processes are high-priority for Moderate Risk clearance due to fraud and conflict-of-interest concerns.

• Contracting Officers and Specialists: Individuals with the authority to obligate the United States to a financial commitment, make contract awards, and administer contracts. Their decisions directly impact billions in federal spending.
• Financial Managers and Budget Analysts: Those with programmatic or certifying authority over large budgets, grants, or cooperative agreements.
• Auditors and Inspectors General (IG) Staff: Particularly those conducting audits of sensitive programs or investigations into fraud, waste, and abuse. Their access to confidential financial and operational data is extensive.
• Loan Officers and Underwriters: For agencies like the Small Business Administration (SBA) or the Department of Veterans Affairs (VA), where decisions involve significant public funds and sensitive applicant information.

3. Information Technology (IT) and Cybersecurity Roles

With the critical nature of federal IT infrastructure, many technical roles require a Moderate Risk Public Trust to access sensitive systems and data.

• System Administrators and Network Engineers: Especially those with privileged access (root, administrator) to agency networks, servers, and core infrastructure. Their position allows them to view, alter, or delete vast amounts of sensitive data.
• Cybersecurity Analysts and Incident Responders: These professionals monitor networks for threats, have access to security event logs containing sensitive information, and are involved in responding to breaches.
• IT Security Specialists: Responsible for configuring security tools, managing firewalls, and implementing access controls.
• Database Administrators: With administrative rights to databases containing sensitive personal, financial, or operational information.

4. Human Resources and Personnel Management

Roles that handle highly sensitive personal information about federal employees, applicants, and sometimes even members of the public.

• Human Resources Specialists (Senior/Managerial): Those with authority to make hiring decisions, process security clearances, or manage sensitive employee relations issues.
• Employee and Labor Relations Specialists: Handle confidential grievances, disciplinary actions, and medical information.
• Retirement and Benefits Specialists: Process complex cases involving sensitive medical and financial data for federal retirees and employees.

5. Health Care and Clinical Positions

Within federal health systems (VA, Department of Defense Military Treatment Facilities, NIH Clinical Center), the standard is often elevated due to the sensitivity of medical records.

• Physicians, Nurses, and Allied Health Professionals: In many federal facilities, access to patient medical records under the Health Insurance Portability and Accountability Act (HIPAA) requires at least a Moderate Risk Public Trust.
• Health Services Administrators and Managers: Overseeing clinical

5. Health Care and Clinical Positions (Continued)

• Health Services Administrators and Managers: Overseeing clinical operations, budgets, and personnel within federal health facilities. They access sensitive patient aggregate data, financial records, and staffing information.
• Medical Records and Health Information Technicians: Handle protected health information (PHI) directly, requiring access to comprehensive electronic health records (EHRs) for patient care, billing, and research purposes.
• Pharmacists and Pharmacy Technicians: Dispense medications and manage prescription databases containing sensitive patient health information.

6. Procurement, Contracting, and Acquisition Roles

Positions managing the spending of federal funds and overseeing contractors, often involving confidential procurement strategies and sensitive bid information.

• Procurement Analysts and Contracting Officers: Especially those negotiating major contracts, handling proprietary contractor data, or managing critical supply chains. They access financial systems, contractor performance data, and sensitive acquisition planning documents.
• Grant Specialists (in agencies like HHS or NSF): Manage applications, awards, and financial reporting for federal grants, accessing sensitive applicant and recipient information.

7. Legal and Compliance Positions

Roles involved in interpreting laws, regulations, and internal policies, often requiring access to confidential case files, investigative reports, or privileged communications.

• Attorneys (Agency Counsel): Provide legal advice, represent the agency in disputes, and access privileged communications and sensitive case materials.
• Paralegals and Legal Assistants: Support attorneys by researching case law, managing discovery, and handling confidential legal documents and evidence.
• Compliance Officers and Inspectors: Conduct audits and investigations into agency adherence to laws and regulations, accessing internal reports, financial records, and operational data.

8. Scientific and Technical Research Roles

In agencies like the Department of Energy (DOE), National Institutes of Health (NIH), or National Aeronautics and Space Administration (NASA), protecting sensitive research data and technologies is paramount.

• Scientists and Researchers: Accessing sensitive unpublished research data, classified materials (if applicable), intellectual property, or controlled technologies.
• Laboratory Managers and Technicians: Managing secure facilities and handling potentially hazardous or sensitive materials, including biological agents, controlled chemicals, or proprietary research samples.

9. Senior Administrative and Program Management Roles

Positions with broad oversight responsibilities that require access to high-level strategic information, sensitive interagency communications, and program performance data.

• Program Managers (Senior Levels): Overseeing large-scale federal programs, accessing detailed budgetary information, performance metrics, sensitive stakeholder communications, and strategic plans.
• Executive Assistants and Senior Staff: Supporting high-level officials (SES/Flag Officers) with access to sensitive correspondence, meeting minutes, policy drafts, and confidential personnel matters.
• Public Affairs Officers (Senior): Crafting responses to sensitive inquiries, managing communications during crises, and accessing internal deliberations and sensitive public information.

Conclusion

The Moderate Risk Public Trust designation serves as a critical safeguard within the federal government, ensuring that individuals entrusted with significant responsibility and access to sensitive information are thoroughly vetted. As outlined across diverse functional areas—from law enforcement and finance to IT, healthcare, procurement, law, research, and senior administration—these roles are fundamental to national security, the efficient use of taxpayer dollars, the protection of individual privacy, and the integrity of federal programs. The rigorous background investigation and continuous monitoring associated with this level of trust are not bureaucratic hurdles; they are essential measures to maintain public confidence and protect the sensitive data and systems vital to the functioning of the government. Ultimately, the MRPT framework balances the operational necessity of access with the paramount need for accountability and security, upholding the principle that those serving in such positions must be demonstrably worthy of the public trust they hold.
