Public Safety Factors in the federal Bureau of Prisons are mandatory classification overrides that force a higher security placement regardless of your point score. When the BOP designates you to a facility, it first runs a point calculation covering criminal history, offense severity, time remaining, age, education, and other variables. A PSF sits on top of that score and sets a hard floor: even if your points qualify you for a camp, a qualifying PSF can require Low, Medium, or High security instead. Only the Administrator of the Designation and Sentence Computation Center can waive one.
What a PSF Actually Does
Think of a PSF as a one-way ratchet. It can push your security level up. It cannot pull it down. If your points already put you at Medium and you carry a PSF that requires Low, nothing changes because you are already above the floor. If your points put you at Minimum and you carry a Sex Offender PSF, the factor overrides the score and places you at Low security or higher.
All PSFs share one baseline consequence: they block placement in a minimum-security Federal Prison Camp, the setting with the least physical security and the most freedom of movement. Several go further, mandating Medium or High security, and two of the female-specific factors route the person to a designated administrative unit rather than a generic security level.
The point score does not disappear once a PSF attaches. It continues to matter for reclassification and later transfers. But until the PSF is waived, resolved, or aged out, it controls the floor.
The Full List of Public Safety Factors
Program Statement 5100.08 defines each PSF, the trigger, and the floor it sets. Some apply only to men, some only to women, and several apply to both.
Factors That Apply to Males
Greatest Severity Offense (Code C) applies when the current conviction sits in the highest tier of the BOP’s Offense Severity Scale. Qualifying offenses include homicide, robbery, carjacking, kidnapping, espionage, and large-scale drug trafficking above specified weight thresholds. Floor: Low security.
Disruptive Group (Code B) applies to validated members of gangs or disruptive groups tracked in the BOP’s Central Inmate Monitoring System. This is the most restrictive male PSF. Floor: High security, meaning a United States Penitentiary.
Sentence Length (Code I) is tiered and shifts automatically as time is served. More than ten years remaining sets a Low floor. More than twenty years remaining sets a Medium floor. More than thirty years, including non-parolable life sentences, sets a High floor. Someone who arrives with twenty-five years remaining starts at Medium; when the remaining time drops under twenty years, the floor drops to Low; under ten years, the PSF drops off entirely if nothing else is attached.
One structural note for men: there is no standalone PSF for a violent history. Violence generates points inside the scoring system, up to seven points for serious violence in the last five years, and those points flow into the security level through the normal calculation. The Disruptive Group and Greatest Severity factors capture some of that risk, but a male prisoner whose violent background does not fit either of those categories has his violence accounted for only through points, not through an override.
Factors That Apply to Females
Violent Behavior (Code K) applies when a female prisoner has two or more convictions or disciplinary findings for serious violence within the past five years. Floor: Low security.
Serious Escape (Code L) applies to involvement in a serious escape within the last ten years. Placement: the Carswell Administrative Unit.
Prison Disturbance (Code M) applies to involvement in a significant institutional disturbance. Placement: the Carswell Administrative Unit.
Factors That Apply to Both
Sex Offender (Code F) applies when the current conviction or prior history involves a qualifying sexual offense. It also captures conduct documented in the pre-sentence report even where the person ultimately pleaded to a different charge. Floor: Low security.
Threat to Government Officials (Code G) applies when the offense involved threatening or targeting officials such as judges, prosecutors, or law enforcement. Floor: Low security.
Deportable Alien (Code H) applies to any prisoner who is not a U.S. citizen, not only those with an active immigration detainer. Lawful permanent residents are included unless ICE has determined that deportation proceedings are unwarranted or has issued a final decision not to deport. Floor: Low security. This one catches people off guard because there is no criminal-immigration prerequisite; non-citizen status alone triggers it, and the rationale is elevated flight incentive.
Juvenile Violence (Code N) applies to a prisoner currently of juvenile age with any documented instance of violent behavior resulting in a conviction or delinquency adjudication.
Serious Telephone Abuse (Code O) applies to documented abuse of telephone privileges for serious misconduct.
How PSFs Affect Programs and Early Release
Placement is only part of the impact. A PSF can also close off the programs that most affect release date.
Residential Drug Abuse Program
The Residential Drug Abuse Program can earn a successful participant up to a twelve-month sentence reduction. Admission to the program itself is a clinical decision made by the Drug Abuse Program Coordinator. The early release benefit, however, has its own exclusion list. Prisoners with current or prior convictions for sexual abuse offenses committed against minors are ineligible for the early release benefit even if they complete the program. In practice that means someone carrying a Sex Offender PSF based on that kind of offense can still go through treatment but will not get the sentence reduction that draws most people to RDAP.
First Step Act Earned Time Credits
Under the First Step Act, eligible prisoners earn ten days of credit for every thirty days of successful participation in programs and productive activities, with an additional five days for those who maintain a minimum or low recidivism risk score across two consecutive PATTERN assessments. Only prisoners classified as minimum or low risk under PATTERN can actually apply the credits toward an earlier release date.
PSFs do not directly disqualify someone from earning credits, but the overlap with the statutory disqualifying-offense list is heavy. Crimes involving violence, sexual abuse, terrorism, espionage, and drug offenses involving firearms are on the list. A Greatest Severity PSF triggered by qualifying drug trafficking may correspond to the same conviction that appears on the First Step Act exclusion list. The Deportable Alien PSF creates a separate problem: non-citizens subject to a final order of removal can earn credits but cannot apply them toward release.
How a PSF Gets Attached
PSFs are derived from sentencing documents, primarily the pre-sentence investigation report prepared by U.S. Probation. Staff at the Designation and Sentence Computation Center review the PSR, the judgment and commitment order, and other central file documentation to determine which factors apply. The initial designation usually happens before you ever arrive at a facility.
This is where most classification disputes start. The PSR is not always accurate. It may describe conduct that was alleged but never proven, or characterize prior offenses in a way that triggers a PSF you do not believe fits. The Sex Offender PSF is a common example: the BOP can apply it based on behavior described in the PSR even when the person was ultimately convicted of a non-sexual offense as part of a plea. The BOP’s own notification policy acknowledges that a PSF based on behavior that did not result in a sexual offense conviction does not trigger sex offender registration requirements, but the PSF itself can still attach for classification purposes and affect security level for years.
The BOP also relies on the court’s Statement of Reasons, which documents findings on contested issues at sentencing. If your defense disputed facts in the PSR and the court resolved those disputes, the BOP is supposed to defer to the court’s findings in the Statement of Reasons rather than the contested portions of the PSR. Staff specifically look for findings that differ from the PSR on prior sexual misconduct, escapes, violence, immigration status, and threats against government officials, each of which maps directly to a PSF.
Getting a PSF Waived, Removed, or Aged Out
Only the DSCC Administrator can waive a PSF. Waiver requests are submitted on BOP Form 409, with specific sections documenting why the security floor is no longer necessary. In practice, institutional staff prepare and submit the request after concluding that behavior and circumstances support a lower security level. The DSCC then makes the final call.
There is no fixed clock. Program Statement 5100.08 does not set a minimum clear-conduct period before a waiver becomes available, though the policy does require eighteen consecutive months of clear conduct in general population before someone can be considered for a nearer-release transfer. Requests filed with less than a year of clean institutional history rarely succeed. Longer clean time and more time served improve the odds.
Some factors resolve without a waiver. The Sentence Length PSF drops automatically as remaining time crosses each threshold. The Deportable Alien PSF can be removed if ICE or an immigration judge determines deportation proceedings are unwarranted or a final decision not to deport is issued. Factors tied to lookback windows, such as the female Violent Behavior PSF’s five-year window or the Serious Escape PSF’s ten-year window, can lose their basis as time passes.
Challenging an Incorrect PSF
If a PSF is attached based on wrong information, there are two routes.
The first targets the underlying documentation. If the PSR contains factual errors that led to the PSF, a motion filed with the sentencing court can ask for an order to amend the report. Courts have the authority to direct changes to a PSR to reflect findings on contested issues, and probation officers can revise the relevant sections and label the report as amended by order of the court. Because the BOP relies on the PSR, correcting it can remove the factual basis for the PSF.
The second route is the BOP’s Administrative Remedy Program. Start with a BP-9 filed with the Warden within twenty calendar days of the classification decision. If that does not resolve it, appeal on a BP-10 to the Regional Director within twenty calendar days. A final BP-11 goes to the General Counsel within thirty calendar days of the Regional Director’s response. Filings should identify the specific factual or legal error: a misinterpreted prior conviction, reliance on unresolved allegations, or a failure to account for the Statement of Reasons.
Exhausting the Administrative Remedy Program is generally required before a federal court will consider a habeas petition challenging a BOP classification decision. Missed deadlines or skipped steps can close off judicial review entirely, so the paperwork discipline matters as much as the argument.
