How Does the Inmate Classification Process Work?

The federal inmate classification process is how the Bureau of Prisons decides where a sentenced person will be housed, how closely they’ll be supervised, and what programs they can join. Staff score each person on a set of weighted factors, match the total to one of five security levels, and assign a separate custody level that governs day-to-day supervision. Classification is not a one-time event: federal regulations require a review at least every 180 days, and the result affects everything from visiting conditions to First Step Act time credits.

What Goes Into Your Security Point Score

When someone is sentenced to federal prison, the BOP pulls information from the sentencing court, the U.S. Marshals Service, the U.S. Attorney’s Office, and the U.S. Probation Office and enters it into the agency’s classification system.¹ Weighted scores across several categories are added together to produce a security point total.

The categories that generate that total are:

Severity of the current offense, scored from 0 to 7.
Criminal history score, from 0 for a minimal record up to 10 for a score of 13 or higher.
History of violence, weighted by seriousness and how recent it is, up to 7 points for serious violence within the last five years.
History of escapes or attempts, with more recent and more serious incidents scoring higher.
Outstanding detainers, scored by the severity of the pending charge or warrant.
Age. Someone 24 or younger gets 8 points; someone 55 or older gets 0.
Education. A verified high school diploma or GED scores 0; lacking one and not enrolling in a GED program adds 2 points.
Drug or alcohol abuse within the past five years adds 1 point.
Voluntary surrender authorized by the sentencing judge subtracts 3 points.

The raw number is not always the final word.² The BOP also applies Public Safety Factors and Management Variables, which can push someone to a higher or lower facility than the score alone would indicate. A Public Safety Factor might flag a history of sex offenses or significant gang involvement. A Management Variable might account for a need for specialized medical care or a judicial recommendation.

Security Level and Custody Level Are Not the Same Thing

Two separate systems run in parallel, and confusing them is the most common reason people misread their paperwork.

Security level describes the physical facility: its perimeter barriers, housing type, staffing ratio, and detection devices. The BOP classifies institutions into Minimum, Low, Medium, High, and Administrative.¹

Custody level describes how much supervision an individual person requires within whatever facility they are assigned to. There are four:

Community, the least restrictive, which can include housing outside the perimeter and outside work with minimal supervision.
Out, which allows less secure housing and outside work details but requires staff to check on the person at least every two hours.
In, which means regular housing and regular work assignments under normal supervision, but no leaving the secure perimeter for work or programs.
Maximum, the highest level of control, reserved for people identified as seriously assaultive, predatory, escape-prone, or highly disruptive.

Two people at the same Low-security facility can hold different custody levels, meaning one qualifies for outside work details while the other does not.³

The Five Federal Security Levels

Each security level corresponds to a range of point scores and a set of physical characteristics. For men, the ranges are:

Minimum (0–11 points). Federal Prison Camps, typically with no perimeter fencing, the most relaxed movement, and the broadest program access. Visiting may take place beyond the security perimeter under staff supervision.
Low (12–15 points). Double-fenced perimeters and higher staffing than camps. Out or In custody.
Medium (16–23 points). Strengthened perimeters, electronic detection, and more controlled internal movement. Out or In custody only.
High (24+ points). The most secure standard facilities, with reinforced perimeters and the highest staffing ratios. In or Maximum custody.
Administrative (all point totals). Facilities with a special mission, such as medical centers, pretrial detention, or the high-security facility at ADX Florence. Inmates of all security levels are housed here.

Women are classified into Minimum (0–15 points), Low (16–30 points), High (31+ points), and Administrative. There is no separate Medium level for women in the federal system.¹

What Else Drives Placement

Federal law requires the BOP to consider more than security points when picking a specific facility. Under 18 U.S.C. § 3621(b), the BOP must weigh the resources at the facility, the nature and circumstances of the offense, the person’s history and characteristics, any statement from the sentencing judge, and relevant Sentencing Commission policy statements.⁴ The statute also directs the BOP to place someone as close as practicable to their primary residence, ideally within 500 driving miles.

Medical Care Level

Health needs can shape placement as much as security concerns. Each inmate is assigned a medical care level from 1 to 4. Level 1 covers generally healthy people who need only routine preventive care. Level 2 includes stable chronic conditions requiring regular monitoring. Levels 3 and 4 cover serious or unstable conditions, including advanced cancers, severe cardiac or neurological disorders, and complex psychiatric needs. Someone classified at Level 4 may be placed in a specialized federal medical center regardless of where their security points would otherwise send them.⁵

Central Inmate Monitoring

Some inmates carry a Central Inmate Monitoring designation, which adds oversight to every placement decision. CIM categories include people in witness protection, those who have made threats against government officials, inmates who received widespread media attention, members of disruptive prison groups, and inmates who must be physically separated from specific other people in federal custody.⁶ A CIM designation does not automatically change security level, but it restricts which specific facilities are available and requires the regional or national office to approve any transfer.

The Initial Classification Timeline

Once you arrive at your designated facility, staff must complete your initial classification within 28 calendar days. You get at least 48 hours’ notice before your classification hearing and are expected to attend in person. A unit team reviews your background, identifies program needs, and produces a Program Review Report with a correctional plan for your situation. You and the Unit Manager both sign it, and you receive a copy.⁷ Every sentenced person who is physically and mentally able is also assigned to a work program at this initial classification.

Why Classification Affects Your Release Date

Classification does not just decide where you sleep. It shapes how quickly you can earn your way out.

First Step Act Time Credits

Eligible inmates earn 10 days of time credits for every 30-day period of successful participation in recommended programs or productive activities. If your PATTERN risk assessment classifies you as minimum or low risk for recidivism, and you have held that rating for at least two consecutive assessments, you earn 15 days instead.⁸ Over a multi-year sentence, the difference between 10 and 15 days a month adds up to months of earlier release, which makes your risk classification one of the most consequential numbers in the federal system.

Residential Drug Abuse Program

The Residential Drug Abuse Treatment Program offers up to 12 months of early release for people who complete it and were sentenced for a nonviolent offense. A long list of current and prior convictions disqualifies applicants. If your current offense involved a firearm, physical force, or a serious risk of violence, you are ineligible. The same applies if you have a prior conviction within the past 10 years for crimes like robbery, arson, kidnapping, or aggravated assault.⁹ Classification matters here because your security designation and custody level affect whether you can be placed at a facility that runs RDAP and whether you qualify for the community-based component that completes the program.

Visiting

Every inmate is entitled to at least four hours of visiting per month, regardless of security level. The real difference is location. Minimum and low-security facilities can allow visiting outside the secure perimeter; medium and high-security institutions keep all visiting inside it.¹⁰ Handshakes, embraces, and a brief kiss at the start and end of visits are generally permitted unless there is specific evidence that contact would create a security risk. Inmates approved for placement at ADX Florence may be limited to non-contact visits behind glass.

Ongoing Reviews

Reviews happen at least every 180 days. Within 12 months of your projected release date, that tightens to every 90 days.⁷ A review can also be triggered off-schedule by a disciplinary incident, a change in medical or mental health status, or the completion of a significant program.

At each review, the unit team reassesses your security point total and custody level. Points can go down as your offense ages, as you earn a GED, or as substance abuse history moves beyond the five-year window. A clean disciplinary record and consistent program participation can support reclassification to a lower security level or transfer to a less restrictive facility. The reverse is also true. A serious disciplinary infraction can trigger immediate reclassification and transfer to a higher-security institution.

For inmates with a CIM designation, the warden must ensure CIM status is reviewed at every program review. If staff believe the assignment should be modified or removed, they must notify the reviewing authority, who makes the final decision.¹¹

Challenging a Classification Decision

If you believe your security designation or custody classification is wrong, the BOP’s Administrative Remedy Program provides a formal grievance process on a strict timeline:

Informal resolution with staff first.
BP-9 filed with the Warden within 20 calendar days of the event.¹²
BP-10 appeal to the Regional Director within 20 calendar days of the Warden’s response.
BP-11 final appeal to the General Counsel within 30 calendar days.¹³

The appeal to the General Counsel is the final step within the BOP. Certain specialized placements, like Control Unit assignments, skip the lower levels and go directly to the General Counsel.

Even after exhausting administrative remedies, judicial relief is narrow. The Supreme Court held in Meachum v. Fano that the Due Process Clause does not give an incarcerated person a constitutional right to any particular facility or classification level. Courts will rarely second-guess a BOP classification decision unless there is evidence of an equal protection violation, such as race-based assignment, or a violation of the BOP’s own published policies.

A Note on State Prisons

Everything above applies to the federal Bureau of Prisons. State prison systems use broadly similar frameworks, with risk assessment tools, security levels, and periodic reclassification reviews, but the scoring instruments, level names, point ranges, and review schedules vary significantly. Some states use three security tiers; others use six. If you or a family member is in a state facility, the state department of corrections typically publishes its classification procedures online or makes them available through the institution’s law library.
