Security clearances dominate the conversation in government contracting circles, but the majority of federal contractor positions don’t require a security clearance at all. They require something different: a Public Trust suitability determination. And yet, for many contractors, Public Trust positions are the most poorly understood and most poorly planned element of their entire workforce model. That misunderstanding has real consequences: start-date delays, compliance findings, and staff who can’t access the systems they need to do their jobs.
In this blog, we break down the complexities of Public Trust hiring to help prime contractors accelerate onboarding and protect their next federal award.
The Top 5 Critical Success Factors for Public Trust Staffing
Getting Public Trust candidates cleared and billable requires a process tailored to OPM suitability. Here are the five key steps to streamline your federal civilian onboarding:
1. Public Trust Is Not a Clearance, But It’s Not Nothing Either
- Security clearances grant access to classified national security information under Executive Order 13526
- Public Trust determinations grant access to sensitive federal systems, PII, and positions of public trust under OPM suitability regulations (5 CFR Part 731)
A candidate can hold an active DoD Secret clearance and still require a separate Public Trust determination for a federal civilian agency role. The two processes are conducted under different legal authorities, by different adjudicating entities, and using different evaluation criteria. Never assume one substitutes for the other without explicit agency confirmation.
The Key Takeaway: Public Trust is the baseline vetting requirement for most of the federal contractor workforce. Its timelines, adjudicative standards, and compliance requirements deserve the same strategic attention you give to your cleared workforce.
2. Public Trust Risk Tiers
- Low Risk (Tier 1): NACI; for non-sensitive roles with limited system access; typically completes in 4–8 weeks
- Moderate Risk (Tier 2): MBI; required for access to sensitive systems, PII, or financial data; typically completes in 3–6 months
- High Risk (Tier 4): BI; required for positions with significant system authority or large-scale sensitive data access; typically completes in 6–12 months
The position risk designation is set by the agency, not the contractor. Review the Position Designation System (PDS) documentation for each role. Misidentifying risk tier leads to either over-vetting (wasting time and money) or under-vetting (creating compliance exposure).
Reference OPM’s Suitability Executive Agent guidance for position designation and adjudication standards.
3. What OPM Is Actually Evaluating
Public Trust adjudications evaluate candidate suitability against 9 OPM suitability criteria under 5 CFR § 731.202: misconduct or negligence in employment; criminal or dishonest conduct; material false statements; alcohol abuse; illegal use of drugs; known or suspected foreign agent activity; abuse of authority; knowing violation of national security laws; and patterns of behavior indicating poor judgment, untrustworthiness, or unreliability.
Many HR professionals familiar with clearance adjudication are not fluent in OPM suitability standards. This creates silent compliance risks when vetting is handled by staff with clearance experience but no Public Trust adjudication background, a gap that cleared recruitment specialists are well positioned to address.
4. The SF-85 and SF-85P: Getting It Right the First Time
Incomplete, inaccurate, or inconsistent SF-85/SF-85P submissions are one of the leading causes of Public Trust investigation delays. Contractors should invest in candidate preparation materials that explain how to complete these forms accurately, particularly regarding employment history gaps, foreign contacts, financial disclosures, and prior legal issues.
Reminder: Material false statements on SF-85 or SF-85P are themselves a disqualifying suitability factor. Candidates who omit unfavorable information create a more serious problem than the underlying issue itself. Candid pre-screening and candidate education prevents this.

5. Managing Your Public Trust Pipeline in Practice
- Initiate investigations at offer acceptance: not at contract start; every day of delay extends your onboarding timeline by a day
- Maintain Interim Access protocols: where the agency permits, many agencies allow contractors to begin work under interim access while full investigations are being completed
- Track investigation status actively: through e-QIP or the agency’s HR security system; don’t assume investigations are progressing
- Build attrition assumptions into your plan: model 5–15% attrition depending on role sensitivity and candidate pool
- Re-investigate on schedule: track reinvestigation dates as compliance obligations, not optional renewals

The Bottom Line: Public Trust positions are the backbone of the federal contractor workforce and the most frequently misunderstood hiring requirement in government contracting. Contractors who invest in understanding suitability tiers, OPM adjudicative criteria, SF-85 completion quality, and pipeline management best practices will build a faster, more compliant, and more competitive workforce across every federal agency they support.
Public Trust hiring is often underestimated, yet it underpins the majority of the federal contractor workforce. Unlike traditional security clearances, it requires a distinct understanding of OPM suitability standards, risk tiers, and investigation processes that directly impact onboarding timelines and compliance outcomes. Contractors that treat Public Trust staffing with the same strategic rigor as cleared hiring, through accurate role designation, thorough pre-screening, and proactive pipeline management, are far better positioned to avoid delays, reduce attrition, and maintain uninterrupted contract performance.
