TIME & CREDITS — PATTERN RISK SCORE

The PATTERN Score, Explained: The Number Behind the Credits

One number quietly governs the entire First Step Act system: the PATTERN recidivism risk level. It sets the credit earning rate, gates whether credits apply toward release, and shapes program assignments. Most families have never seen it. This guide explains what PATTERN measures, when it changes, and how to read an assessment like an auditor.

What it is	Prisoner Assessment Tool Targeting Estimated Risk and Needs — the BOP’s recidivism risk instrument, mandated by the First Step Act
Risk levels	Minimum, Low, Medium, High — computed separately for general and violent recidivism, with distinct male and female scoring
Why it matters	Two consecutive Min/Low assessments unlock the 15-days-per-30 earning rate; Min/Low status gates applying credits toward early release

Where PATTERN came from

The First Step Act ordered the Department of Justice to build a risk and needs assessment system, and PATTERN — the Prisoner Assessment Tool Targeting Estimated Risk and Needs — is the result, first released in 2019 and revised several times since. It is a statistical instrument: it scores factors correlated with reoffending and sorts people into minimum, low, medium, or high risk categories, separately for general recidivism and violent recidivism, with different scoring for men and women.

PATTERN is not a judgment about character and it is not a sentence — but under the FSA’s architecture it has sentence-like consequences, which is why it deserves the same auditing attention as the credit math itself. The Department of Justice publishes review reports on the tool, and its scoring instruments are public documents; families are allowed to understand exactly how the number is built.

What goes into the score

PATTERN combines static factors — the ones history fixed, like age at assessment, criminal history score, and the nature of the offense — with dynamic factors the person can influence: infraction history and recency, program completions, work assignments, education progress, and drug treatment participation. Each factor carries points; the total maps to a risk level through published cut points.

The design has a hopeful implication that families should hear clearly: the score is built to fall over time. Aging alone helps. Clean conduct helps. Every completed program and education milestone helps. A person who entered at medium can, and very commonly does, reach low — and the two-consecutive-assessment rule means the payoff compounds once they hold it. Our guide to programs that earn credits doubles as a map of score-reducing activity.

The two doors PATTERN opens

Door one is the earning rate. Everyone eligible earns FSA credits at 10 days per 30 of successful programming; a person who has been assessed minimum or low on two consecutive assessments earns at 15 days per 30. Over a year of steady programming, that difference is two full months — which is why a rate stuck at 10 despite a low-low history is one of the costliest errors on our miscalculation list.

Door two is application. To apply credits toward early transfer to supervised release, the statute generally requires minimum or low risk; for prerelease custody, minimum or low is the standard path, with a narrow warden-approval route for others. A person earning steadily at medium risk is banking credits they cannot yet spend — the score, not the balance, is their bottleneck, and score-reduction becomes the strategic priority.

When and how reassessment happens

PATTERN is scored at intake and reassessed on the unit-team cycle — the statute requires periodic reassessment, and in practice it rides the program review schedule, at least annually and typically more often as release approaches. Reassessment is where dynamic-factor progress cashes in: completed programs, clean conduct time, and education entries only move the number when someone actually rescores it.

That makes program reviews appointments to prepare for, not endure. The person inside should arrive with a list of completions since the last review and confirm they are entered; the family’s job is keeping the certificate file that makes the list undeniable. Ask for the resulting risk level and date at each review, and log it — a home-side history of scores and dates is the raw material for every challenge that might follow.

Reading an FSA assessment like an auditor

The FSA Time Credit Assessment shows the risk-level history alongside credit earnings, and the audit is a matching exercise. Find the date of the second consecutive minimum/low assessment; the earning entries after that date should show the 15-day rate. Confirm reassessments actually occurred on schedule — a two-year-old score is itself a problem, because a person cannot start the two-consecutive clock on assessments nobody performed.

Then check consistency: risk level on the assessment versus what the team says versus what program assignments assume. Mismatches happen, especially after transfers between institutions, and each one is a specific written question: the assessment dated March shows LOW, the second consecutive LOW, yet earnings since remain at 10 days per 30 — please correct or explain. Paper beats conversation, every time.

Challenging a score that is wrong

PATTERN challenges come in two species. Data errors — a criminal-history input that contradicts the presentence report, a program completion never entered, an infraction that was expunged on appeal still counting — are the strong species, because they are documentary. Raise them at the program review with the paper attached, and escalate through the BP process if uncorrected. Our companion guide on challenging a PATTERN score walks the drafting.

Disagreement with the tool itself — believing the cut points are unfair or a static factor overweighted — is the weak species inside the BOP, because staff apply the instrument as published. Those critiques are real and are being litigated and studied nationally, but a family’s leverage is in the inputs, the arithmetic, and the reassessment schedule. Fight where the process gives you a handhold.

Strategy: living with the number

For a person at medium or high, the playbook is patience with structure: request programming aligned to assessed needs, keep conduct clean, and treat every reassessment as a checkpoint toward the two-consecutive threshold. The credits earned at 10 days along the way are not wasted — they bank toward prerelease custody once application conditions are met, and the balance plus an improved score can move the conditional placement dates dramatically in a single recalculation.

For a person already at minimum or low, the playbook is protection: the score is now an asset, and incident reports are the main threat to it. Either way, the family role is the same one that runs through this entire site — keep the records, calendar the reviews, and turn every question into writing. The number is knowable, improvable, and auditable. Treat it that way.

Frequently asked questions

What is a PATTERN score in federal prison?

PATTERN is the BOP’s recidivism risk assessment, required by the First Step Act. It scores static and dynamic factors and assigns minimum, low, medium, or high risk levels — which control the FSA credit earning rate and whether earned credits can be applied toward release.

How does someone get the 15-days-per-30 earning rate?

By being assessed at minimum or low risk on two consecutive PATTERN assessments. The enhanced rate should apply from the second qualifying assessment forward — verify the earning entries actually changed on that date.

How often is the PATTERN score updated?

It is assessed at intake and reassessed on the program-review cycle — at least annually, and more frequently as release nears. Progress only moves the number at reassessment, so confirming completions are entered before each review matters.

Can a PATTERN score go down?

Yes — the tool includes dynamic factors, so clean conduct, completed programming, education, work, and simply aging reduce scores over time. Movement from medium to low is common and unlocks both the higher earning rate (after two consecutive assessments) and credit application.

Can you challenge a PATTERN score?

Data errors in the inputs — wrong criminal history, missing completions, expunged infractions — are challengeable at program reviews and through the administrative remedy program with documentation. Disagreement with the tool’s design itself is not something institution staff can fix.
