First Step Act Risk and Needs Assessment: PATTERN Levels and Credits

The PATTERN risk assessment is the scoring tool the federal Bureau of Prisons uses to rate every person in federal custody on their likelihood of reoffending. It produces two scores — one for general recidivism and one for violent recidivism — and slots each inmate into one of four tiers: Minimum, Low, Medium, or High. That tier controls how fast you earn First Step Act time credits, whether you can spend those credits on a halfway house or home confinement, and how soon you can move to supervised release.1Federal Bureau of Prisons. PATTERN Risk Assessment

PATTERN (Prisoner Assessment Tool Targeting Estimated Risk and Needs) was built to satisfy 18 U.S.C. § 3632, which required the Attorney General to develop a risk and needs system for the federal prison population. The current version is 1.3.

What the Tool Actually Scores

PATTERN uses 15 scored items divided into two groups. Static items reflect your history and don’t change. Dynamic items reflect what you’re doing now and can change with every reassessment.2Office of Justice Programs. First Step Act of 2018 Risk and Needs Assessment System The higher of your two scores — general or violent — is what determines your classification.

Static Factors

These are set by your record. You cannot lower them.

  • Age at assessment. Younger inmates score substantially higher; someone under 26 carries far more points than someone over 60.
  • Whether the current offense was violent. A violent instant offense adds points to both scales.
  • Sex offense history, current or prior, on the general scale.
  • Criminal history score. This is the single largest static contributor. A criminal history score above 12 alone adds 40 points to the general scale.
  • Escape history, scored by severity and how recently it happened.
  • History of violence separate from the instant offense, weighted by severity and recency.

Dynamic Factors

These are where behavior during a sentence moves the number. Every one of them is scored again at each review.

  • Disciplinary infractions. Total count, severity, and how recently the last one occurred are all scored. Twelve months clean earns the best score on these items.
  • Programs completed. Completing more than 10 programs earns the maximum reduction on the general scale (negative 8 points). Even one completed program starts moving the score down.
  • Work programming. Participation subtracts points from both scales.
  • Drug treatment. Residential drug treatment earns a larger reduction than non-residential. Having no substance abuse need identified earns the best score on this item.
  • Education. A verified high school diploma or GED subtracts points. Being enrolled in and progressing through a GED program earns a partial reduction.
  • Financial responsibility. Noncompliance with court-ordered financial obligations adds points.

The point is straightforward: you can’t rewrite your criminal history, but you can pull your overall score down enough to cross into a lower tier by staying out of trouble, completing programs, and finishing education.

The Four Risk Levels

PATTERN assigns every inmate to Minimum, Low, Medium, or High.3Office of the Law Revision Counsel. 18 USC 3632 – Development of Risk and Needs Assessment System Cutoffs differ by gender, and the general and violent scales use different ranges. Your final classification is whichever tier is higher across the two scales.

For men on the general recidivism scale, the ranges work out roughly like this: Minimum sits below 6, Low runs from about 6 through 39, Medium covers 40 through 54, and High applies at 55 and above. The violent scale uses a narrower range. Women are scored on separate cutoffs calibrated to the female prison population, with generally lower thresholds at each tier.

Two things flow from the tier. First, your credit-earning rate. Second, whether you can actually apply earned credits to leave prison earlier. Minimum and Low have advantages on both fronts.

How the Score Drives Time Credits

Eligible inmates earn 10 days of First Step Act time credits for every 30 days of successful participation in approved recidivism reduction programs or productive activities. The rate rises to 15 days per 30-day period for inmates classified as Minimum or Low risk who have not increased their risk level across two consecutive assessments.3Office of the Law Revision Counsel. 18 USC 3632 – Development of Risk and Needs Assessment System Over a multi-year sentence, that 50% bump compounds.

Something that catches people off guard: credits are not automatic. You have to opt in by completing needs assessment surveys through the TRULINCS system. Declining recommended programming that matches an identified need places you in opt-out status, and you earn nothing until you reverse it and re-engage.4Federal Bureau of Prisons. First Step Act Approved Programs Guide

Medium and High risk inmates can still earn credits at the base 10-day rate. What they generally cannot do is apply them to an earlier release without first moving down to Minimum or Low. Earning credits and applying credits are two separate gates.

Applying credits is governed by 18 U.S.C. § 3624(g). Once accumulated credits equal the time remaining on the sentence, the BOP may transfer the inmate to prerelease custody — a Residential Reentry Center or home confinement — or to an early start of supervised release.5Office of the Law Revision Counsel. 18 USC 3624 – Release of a Prisoner For prerelease custody, the inmate needs Minimum or Low on the last two reassessments; alternatively, a warden may approve transfer after finding the inmate is not a danger, has genuinely worked to reduce risk, and is unlikely to reoffend. For early transfer to supervised release, the inmate needs Minimum or Low on the most recent reassessment. That early transfer is capped at 12 months and shortens time in prison, not the supervised release term itself.

Home confinement under these provisions comes with 24-hour electronic monitoring, and the inmate can leave only for approved activities like work, programming, medical care, religious services, and family-related reentry activities.

Who the System Locks Out

A long list of offenses permanently disqualifies an inmate from earning any First Step Act time credits, no matter how low their PATTERN score goes. The categories include terrorism, sexual abuse and child exploitation offenses, most federal homicides, kidnapping, firearms offenses under 18 U.S.C. § 924(c), espionage and treason, biological, chemical, and nuclear weapons offenses, certain fentanyl, heroin, or methamphetamine offenses involving a leadership role or resulting in death or serious injury, arson, carjacking, destruction of aircraft or vehicles, and assaults on federal officials involving deadly weapons or bodily injury.6Office of the Law Revision Counsel. 18 USC 3632 – Development of Risk and Needs Assessment System The BOP publishes the full list of disqualifying statutes.7Federal Bureau of Prisons. First Step Act Time Credits Disqualifying Offenses

A separate rule targets application, not earning. Anyone subject to a final order of removal under federal immigration law cannot apply earned credits toward prerelease custody or early transfer to supervised release, even if they are otherwise eligible.8eCFR. 28 CFR Part 523 Subpart E – First Step Act Time Credits Credits can still be earned; they just don’t move the release date.

How Often the Score Updates

The BOP conducts a program review at least once every 180 calendar days.9Federal Bureau of Prisons. Program Statement 5322.13 – Inmate Classification and Program Review At each review, the Case Manager updates the dynamic factors: new infractions, programs completed since the last review, education changes, drug treatment progress. The score is recalculated and the classification adjusted. Reviews may come more frequently as an inmate approaches release.

The 180-day rhythm is what gives the “two consecutive assessments” requirements their teeth. The accelerated 15-day earning rate needs Minimum or Low on two back-to-back reviews with no risk-level increase. Prerelease custody transfer needs Minimum or Low on the last two reassessments. A single bad review can push eligibility out by six months to a year.

It also cuts the other way. Someone who arrives at Medium can drop into Low by completing programs, staying discipline-free, and finishing a GED. The next review is the door.

Challenging a Score You Think Is Wrong

If your PATTERN score reflects something incorrect — an infraction that was later expunged, a completed program that wasn’t recorded, a miscoded criminal history item — the BOP’s Administrative Remedy Program is the formal route to fix it. The same process covers disputes over time credit calculations and denials of credit application.10eCFR. 28 CFR Part 542 – Administrative Remedy Program

There are four steps:

  • Informal resolution with staff. Required before anything formal.
  • Institutional level. File form BP-9 with the Warden within 20 calendar days of the event you’re challenging.
  • Regional appeal. File form BP-10 with the Regional Director within 20 calendar days of the Warden’s response.
  • National appeal. File form BP-11 with the General Counsel within 30 calendar days of the Regional Director’s response.

If the BOP misses a response deadline at any level, you can treat the silence as a denial and move up. Exhausting this process is also a prerequisite before taking any challenge into federal court, so missing a step or a deadline can matter well beyond the immediate dispute.
