Eligibility to earn vs. eligibility to apply
The First Step Act draws a line that trips up a surprising number of families, and even some staff. Eligibility to earn credits is governed by 18 U.S.C. §3632(d)(4) and its exclusion list — it asks whether the offense of conviction lets a person accumulate credits at all. Eligibility to apply those credits toward an earlier date is a separate question under §3624(g), turning on PATTERN risk level, detainers, and whether earned credits equal the sentence remainder.
A person can be fully eligible to earn, banking credits every month, and still see no movement in their release date because an application condition is unmet. Confusing the two is the source of endless frustration. This page is about the first question — earning eligibility — which is where a wrongful exclusion does the most damage, because it zeroes out the benefit entirely. Our flagship guide walks the full machine end to end.
The exclusion list — what it actually covers
Congress wrote the disqualifying offenses into §3632(d)(4)(D). The categories are, broadly: offenses involving violence; terrorism; espionage; human trafficking; sex offenses and sexual exploitation; certain firearms offenses, including a repeat felon in possession; and certain high-level drug offenses such as continuing criminal enterprise and specified large-quantity trafficking. The BOP publishes the full enumerated list, and it is long and specific.
Two features matter enormously. First, the list turns on the offense of conviction — the statute the person was actually convicted under, as reflected in the judgment — not on conduct described in the presentence report or the original indictment. Second, a person excluded from earning FSA credits still earns good conduct time under §3624(b) and may still access other programming. Exclusion from FSA credits is not exclusion from every benefit.
Why the offense of conviction is everything
This is the point families most often miss and case managers most often get wrong. A presentence report may describe violent conduct, a dismissed count, or a sentencing enhancement — but if the person was ultimately convicted under a statute that is not on the exclusion list, they are eligible to earn. The reverse is also true: a single excluded count of conviction can disqualify credit earning even where the rest of the case looks qualifying.
The recurring error we see is a case manager coding someone ineligible based on the general character of the case rather than the precise statute in the judgment. A dismissed §924(c) count, a stricken enhancement, or a misread drug subsection can quietly control the outcome. The fix always starts with the paper: the judgment and commitment order, read against the enumerated list, subsection by subsection.
The three most common wrongful-exclusion patterns
First, the dismissed-count error: a count that was dismissed as part of a plea is treated as if it were a conviction. Second, the drug-subsection error: a conviction under 21 U.S.C. §841(b)(1)(C) — which carries no mandatory minimum and is not a high-level exclusion — is confused with an excluded high-quantity subsection. Third, the enhancement error: a sentencing enhancement is mistaken for an element of an excluded offense.
Each of these is documentable and therefore challengeable. The person inside can request their FSA Time Credit Assessment and sentence computation, compare the coded offense against the judgment, and — where there is a mismatch — raise it in writing. A specific, paper-anchored question is far harder for staff to wave away than a general complaint that the math seems wrong.
How to challenge a wrong determination
The ladder is the same one that governs most BOP disputes, and it usually must be climbed in order. It begins informally: the person raises the discrepancy with their case manager or unit team, in writing, quoting the statute of conviction from the judgment and asking why they are coded ineligible. Many errors die here once the specific citation is on the table.
If informal resolution fails, the Administrative Remedy Program begins — BP-8, BP-9 to the warden, BP-10 to the region, BP-11 to the central office — each with deadlines measured in days. Exhausting this process is not busywork: federal courts generally require it before hearing a §2241 challenge, and the paper trail becomes the record if court becomes necessary. Our guide on which offenses qualify covers the offense analysis in detail, and our miscalculation guide covers rate and posting errors.
Eligibility is a starting line, not a finish line
Confirming earning eligibility is the first audit, not the last. Once eligibility is established, the questions shift to earning rate (10 or 15 days per 30), whether the enhanced rate started when the second consecutive minimum or low PATTERN assessment posted, whether retroactive credit was granted, and whether earned credits are actually being applied to move the date.
For families, the practical sequence is simple: establish eligibility on paper first, because everything downstream depends on it, then work through the rest of the computation. Our free calculator produces an independent estimate you can hold against the BOP's numbers once eligibility is settled.
