The design: broad eligibility, listed exclusions
The First Step Act starts from inclusion: a person in BOP custody earns time credits for programming unless their conviction appears on the exclusion list Congress wrote into 18 U.S.C. §3632(d)(4)(D). The list is long — dozens of subsections — but it is a list, closed and specific, keyed to statutes of conviction. The BOP does not have discretion to add to it, and staff impressions about the case do not control. The judgment does.
The Bureau publishes its eligibility determinations through the FSA Time Credit Assessment, where a person is coded eligible or ineligible. That coding decision, made once and often early, silently governs years of earning. Auditing it is the single highest-leverage check in the FSA system, because a wrong ineligible flag zeroes out everything downstream.
The excluded categories, in plain English
The exclusions cluster into families. Violence and homicide: murder, manslaughter, assault with intent, robbery-related convictions under specific statutes, and offenses with terrorism connections. Sex offenses: sexual abuse, exploitation of minors, child pornography offenses, and failure-to-register convictions. Weapons: using or carrying a firearm during a crime of violence or drug trafficking under 18 U.S.C. §924(c), unlawful possession by prohibited persons in specified circumstances, and export-control weapons offenses.
Drugs, narrowly: most drug convictions are eligible, but Congress excluded specified high-culpability postures — organizer/leader enhancements in certain importation contexts and fentanyl-related convictions under particular subsections. National security and misc.: espionage, treason, certain immigration crimes like alien smuggling resulting in death, and a scatter of others. The controlling text is the statute list itself — our sources page links the primary law, and precision matters more here than anywhere else on this site.
The rule that decides close cases: offense of conviction
Eligibility is measured against what the person was convicted of — the counts in the judgment — not against dismissed counts, not against conduct described in the presentence report, and not against how dramatic the case sounded. A person indicted on a §924(c) count that was dismissed in the plea is not excluded by it. A drug defendant whose PSR describes violence but whose conviction is simple §841 trafficking is not excluded by the narrative.
This is where miscoding is born: intake staff reading a file quickly can key the indictment instead of the judgment, or treat relevant conduct as conviction. It also cuts the other way — a person may assume eligibility while one count of a multi-count judgment sits squarely on the list, and one excluded count of conviction is enough to bar earning. The audit is always the same: judgment in one hand, statute list in the other, count by count.
Eligible to earn vs. able to apply: do not confuse the gates
Passing the offense screen means credits can be earned. Whether they can be applied is a second gate with its own rules: a minimum or low PATTERN risk level, a credit balance equal to the time remaining, and no disqualifying immigration posture — a person subject to a final order of removal cannot apply credits toward early release. The gates fail independently, and diagnosing which one is closed determines the entire strategy.
The immigration nuance deserves emphasis because it is widely misunderstood: a detainer alone is not the same as a final order of removal, and the consequences differ across the system — our detainers guide separates the categories. Meanwhile a person blocked at the application gate should usually keep earning anyway; postures change, orders get reopened, and banked credits apply the day the gate opens.
If the offense is excluded: the rest of the toolbox
An excluded conviction closes one door, not the building. Good conduct time — roughly 15% of the sentence — applies regardless. The Second Chance Act authorizes up to 12 months of halfway house and home confinement on reentry grounds with no FSA-style offense screen. RDAP carries its own separate eligibility rules for its sentence reduction. Compassionate release under §3582(c)(1)(A) is available to anyone with extraordinary and compelling circumstances.
Programming also remains worth doing on its own terms: it feeds the PATTERN dynamic factors, supports transfer and placement arguments, and builds the record every later motion draws on. Families of excluded prisoners should grieve the door and then work the building — the site’s pro se guide maps every remaining corridor.
The audit, step by step
One: obtain the judgment and commitment order — PACER for the family, or the person’s own copy inside. Two: obtain the FSA Time Credit Assessment showing the eligibility coding. Three: list every count of conviction with its exact statute and subsection. Four: compare each against §3632(d)(4)(D), reading subsections literally — many exclusions turn on a specific subsection or an element like serious bodily injury, and near misses are misses.
Five: if coded ineligible but no count matches the list, write the challenge: attach the judgment page, quote the coding, and ask the team to correct it or identify the precise statutory basis for exclusion. Six: escalate through the remedy program if the answer is vague — the phrase please cite the specific subsection of 3632(d)(4)(D) relied upon does honest work. A dispute that survives BP-11 with credits at stake is §2241 material.
Gray zones and honest uncertainty
Some questions are genuinely contested: how conspiracy and attempt convictions map onto listed substantive offenses, how prior-conviction-based exclusions operate, and how coding should treat multi-count judgments where counts straddle the line. Courts have split on pieces of this, and the BOP’s own guidance has evolved. When your fact pattern sits in a gray zone, expect the administrative process to hold its position and expect the real answer to come from the district court — or already exist in your circuit’s decisions.
That is also the honest boundary of this page: we can teach the list, the rule, and the audit, but whether a particular contested conviction is excluded can be a genuine legal question about your case — the kind we do not answer, because that is legal advice. A family facing a true gray zone should read our guide on when a lawyer is worth it; input errors are for the process, interpretation battles are sometimes for counsel.
