Federal Prison Security Levels Explained

The Five Levels, and Why the Fifth Is Different

The Bureau of Prisons classifies its institutions as minimum, low, medium and high security, plus a fifth category called administrative. The first four are a ladder. The fifth is not on the ladder at all: administrative facilities are defined by mission, and BOP states they are capable of holding inmates from all security categories. That single fact explains most of the confusion families run into, because a person can be held at an administrative facility for months before ever seeing the security level they were actually designated to.

The names track the levels, and the acronyms are worth learning because BOP uses them everywhere: FPC is a Federal Prison Camp, FCI is a Federal Correctional Institution, USP is a United States Penitentiary, and FCC is a Federal Correctional Complex. Every quotation below is from BOP's own facilities page.

Minimum Security: the Federal Prison Camp

BOP: "Minimum security institutions, also known as Federal Prison Camps (FPCs), have dormitory housing, a relatively low staff-to-inmate ratio, and limited or no perimeter fencing. These institutions are work- and program-oriented."

The operative phrase is "limited or no perimeter fencing." At most camps nothing physical stops a person walking to the road. What holds a camp together is consequence rather than perimeter: leaving is an escape, it is prosecuted, and it converts a short sentence at the easiest place in the system into a long one somewhere much harder. Many camps are satellites attached to a larger institution rather than standalone sites, which BOP calls Satellite Prison Camps. The full roster, with populations and the scoring that decides who is designated there, is in the complete list of federal prison camps. Prisonpedia indexes them individually under minimum-security federal prison camps, 56 entries with conditions, visiting and programs at each.

Low Security: the FCI

BOP: "Low security Federal Correctional Institutions (FCIs) have double-fenced perimeters, mostly dormitory or cubicle housing, and strong work and program components. The staff-to-inmate ratio in these institutions is higher than in minimum security facilities."

On paper the gap between a camp and a low FCI is small. For men, a security point total of 0 to 11 is minimum and 12 to 15 is low. For women, 0 to 15 is minimum and 16 to 30 is low. Three points can be the entire difference, and voluntary surrender is worth three points on its own. That is why the work that decides this happens before sentencing rather than after. A handful of institutions also operate a Federal Satellite Low, a separate low-security unit attached to or affiliated with a main facility. Prisonpedia lists the low-security Federal Correctional Institutions individually, 32 of them.

Medium Security

BOP: "Medium security FCIs (and USPs designated to house medium security inmates) have strengthened perimeters (often double fences with electronic detection systems), mostly cell-type housing, a wide variety of work and treatment programs, an even higher staff-to-inmate ratio than low security FCIs, and even greater internal controls."

The change families notice most is housing. Dormitory or cubicle living gives way to cells. The parenthetical in BOP's own sentence matters too: a facility named as a penitentiary can be designated to hold medium-security people, so the name on the sign does not reliably tell you the level inside. The medium-security Federal Correctional Institutions are indexed separately, 29 entries.

High Security: the United States Penitentiary

BOP: "High security institutions, also known as United States Penitentiaries (USPs), have highly secured perimeters (featuring walls or reinforced fences), multiple- and single-occupant cell housing, the highest staff-to-inmate ratio, and close control of inmate movement."

This is the level people picture when they hear the word prison, and it is not where a first-time non-violent defendant is designated absent something specific driving it there. When a white-collar case does land above low security, a Public Safety Factor is usually the reason rather than the point total. There are only eight high-security United States Penitentiaries indexed, which is a smaller set than most people assume.

Administrative Facilities: a Mission, Not a Level

Administrative facilities have special missions: holding people awaiting trial or sentencing, treating serious medical conditions, and containing the most dangerous or escape-prone people in the system. The category covers Metropolitan Detention Centers and Metropolitan Correctional Centers, Federal Detention Centers, Federal Medical Centers, the Federal Transfer Center in Oklahoma City, and the Administrative Maximum facility at Florence.

Because the category is defined by mission, these institutions hold people of every security classification at once. For most families this is the first federal facility they deal with, long before designation is decided, and it is also frequently the place someone passes through in transit. The transit itself has its own vocabulary, covered in what diesel therapy actually is. The medical side of this category has its own index: Federal Medical Centers.

Federal Correctional Complexes

BOP: "At Federal Correctional Complexes (FCCs), institutions with different missions and security levels are located in close proximity to one another. FCCs increase efficiency through the sharing of services, enable staff to gain experience at institutions of many security levels, and enhance emergency preparedness by having additional resources within close proximity."

This is why a place name alone tells you very little. A complex can contain a penitentiary, a medium or low FCI, and a satellite camp on the same grounds. Two people "sent to" the same named location can be living in conditions that have almost nothing in common.

What Decides the Level

Designation runs on a score. Form BP-337, under Program Statement 5100.08, scores voluntary surrender status, severity of the current offense, criminal history, history of violence, history of escape, type of detainer, age, education, and drug or alcohol history. Public Safety Factors sit on top of the score and frequently override it: certain factors move a person out of minimum security at a perfect point total.

Under 18 U.S.C. 3621(b), BOP places a person as close as practicable to their primary residence and, to the extent practicable, within 500 driving miles, subject to bed availability, security designation, programmatic and medical needs, the recommendation of the sentencing court, and other security concerns. Nobody outside the Bureau designates. What can be done is build the record that supports a designation and advocate for it, which is the facility designation work, and most of it happens before sentencing.

Going Deeper

Each level above links through to Prisonpedia's index for that category, where every institution has its own entry covering conditions, visiting and programs. Its overview of federal prison security levels and of the Bureau of Prisons sit above those. For women, the designation picture is different in ways the general guidance rarely covers: there is no medium-security designation for women at all, and the point thresholds differ at every level. Women's Federal Prison catalogs every federal facility that houses women.

If the practical question underneath all of this is what the first days look like wherever a person lands, your first day in federal prison covers intake step by step.

Why This Distinction Is Worth Getting Right

Sam Mangel served his own federal sentence before he did this work, and the single most common thing he hears from families in the weeks after sentencing is a version of the same question: is it going to be the place they saw on television. Usually it is not. But the answer depends on a point total, a set of factors, and a bed-availability decision that most people never see the inside of, and knowing which of the five levels is actually in play changes what a family should be doing with the time before the report date.
