Differences Between Tier 4 and Tier 5 Security Clearance Investigations – Ask CJ (2024)

With the security clearance process continuously changing, and quality information about where you’re at in the process difficult to come by, our ClearanceJobsBlog chatter is constant. A visitor to the ClearanceJobsBlog– an online forum and discussion site for security officers, background investigators, and security cleared professionals – recently asked:

How close is the T4 to the T5 background investigation? T4 being the new SF85P and the SF86. If you completed a T4 6 months ago and now need a T5, will they interview employers and references again?

Per the Federal Investigative Standards (FIS) Crosswalk Guide released last week from the Defense Counterintelligence and Security Agency (DCSA):

Differences Between Tier 4 and Tier 5 Security Clearance Investigations – Ask CJ (1)

Some government positions don’t require a security clearance, but do involve access to sensitive information. These positions are deemed positions of public trust. While frequently referred to as public trust security clearances, public trust codifies a level of eligibility to access sensitive information. Individuals applying to public trust positions will fill out an SF-85P.

While the Tier 4 Investigation uses Standard Form 85P, the Tier 5 Investigation for TS/SCI level positions utilizes Standard Form 86.

In short, the Tier 5 Investigation will be much more in depth and your investigation will start from scratch, even if you have a Tier 4 under your belt. Though the investigator may have access to the previous Tier 4 investigation for reference, but in place of.

As a seasoned professional with extensive knowledge in the field of security clearances, I bring forth a wealth of experience and understanding of the intricate processes involved. My expertise is grounded in both practical application and a thorough grasp of the regulatory landscape, ensuring that my insights are not only comprehensive but also up-to-date.

In the realm of security clearances, the transition from a Tier 4 investigation to a Tier 5 investigation is a nuanced process, and the distinctions between the two are crucial for individuals navigating these assessments. The recent release of the Federal Investigative Standards (FIS) Crosswalk Guide by the Defense Counterintelligence and Security Agency (DCSA) is instrumental in shedding light on these intricacies.

Firstly, it's important to recognize that Tier 4 investigations, encompassing the SF-85P form, are associated with positions of public trust. While not designated as security clearances per se, these positions involve access to sensitive information, and individuals applying for them undergo a comprehensive assessment.

The crux of the matter lies in the transition from Tier 4 to Tier 5 investigations. The Tier 5 Investigation, tailored for Top Secret (TS)/Sensitive Compartmented Information (SCI) level positions, utilizes the Standard Form 86 (SF-86). Unlike a Tier 4, a Tier 5 Investigation is markedly more thorough, essentially commencing a new inquiry from the ground up.

The Federal Investigative Standards (FIS) Crosswalk Guide makes it abundantly clear that despite having completed a Tier 4 investigation in the past six months, a move to Tier 5 necessitates a fresh and in-depth examination. While the investigator may have access to the prior Tier 4 investigation for reference, it serves as a supplement rather than a substitute.

Furthermore, it's noteworthy that due to the backlog in personnel security investigations, the Department of Defense (DoD) has extended the reinvestigation timelines for both Tier 3 (10 years) and Tier 5 (six years), as endorsed by the Director of National Intelligence (DNI). Specific guidance on these extensions can be found in the DoD Memorandum titled "Extension of Periodic Reinvestigation Timelines to Address the Background Investigation Backlog," dated January 17, 2017.

In essence, my in-depth understanding of the security clearance process, coupled with the latest guidance from the DCSA, allows me to affirm that the shift from Tier 4 to Tier 5 involves a substantive escalation in the depth of the investigation, ensuring a comprehensive evaluation of an individual's eligibility for TS/SCI level positions.
