First Step Act: Overview and Implementation

The First Step Act of 2018 is a United States federal law on sentencing and prison reform for people in federal custody. It reduces some federal mandatory minimum penalties, expands good conduct time, creates earned time credits for participation in programs, and adds new rules for confinement and reentry.

For people in federal custody, this matters because expanded good time and earned time credits can reduce prison time by up to one year, and can shift that period into residential reentry (supervised release) in some situations.

One major limitation exists. The act only applies to people convicted of federal offenses and held in the federal prison system, and only if they haven't been convicted of disqualifying offenses. These generally include violent crimes, terrorism-related offenses, sex offenses, human trafficking, and certain high-level drug offenses.

History of the First Step Act

Years of congressional debate about federal prison growth set the stage for this law. Lawmakers from both major parties worried about long drug sentences, high correctional spending, and the impact of incarceration on families and communities. Earlier bills, such as the Sentencing Reform and Corrections Act, didn't pass but helped build momentum for a combined prison and sentencing reform package.

S. 756 in the 115th Congress became the First Step Act. After negotiations on sentencing provisions, the Senate passed a revised version in December 2018, then the House followed. President Donald Trump signed it into law on December 21, 2018, as Public Law 115-391.

The law breaks into three main parts. First, it directs the Department of Justice and the Bureau of Prisons to create and use a formal risk and needs assessment system for all federal prisoners, with linked programs to reduce recidivism risk. Second, it changes several federal sentencing rules, including drug mandatory minimums, the "safety valve" for some low-level drug cases, and penalties for repeat firearm offenses under 18 U.S.C. § 924(c). Third, it reauthorizes and expands the Second Chance Act, which funds state and local reentry programs.

Congress wrote in specific timelines. The Attorney General had 210 days to develop the risk and needs assessment system. The Bureau of Prisons then had two years to assess all prisoners under that system, expand approved programming, and begin awarding and applying earned time credits for program participation. In July 2019, the Department of Justice released the core tool, known as the Prisoner Assessment Tool Targeting Estimated Risk and Needs (PATTERN), and later updates have revised risk factors and validation data.

Impact on incarcerated people

The First Step Act shapes both custody length and confinement conditions. Good conduct time, earned time credits, sentencing relief, compassionate release, and new rules on placement and conditions all matter here.

Good conduct time changed under 18 U.S.C. § 3624. Eligible federal prisoners now receive up to 54 days of good conduct time for each year of the sentence imposed, instead of each year served. The Bureau of Prisons applied the new calculation in 2019 and adjusted projected release dates, which reduced sentences for tens of thousands of people by weeks or months.

Beyond good conduct time sits another benefit. The act creates earned time credits. Eligible prisoners who complete "evidence-based recidivism reduction programs" or "productive activities" earn credits that shift release dates to earlier prerelease custody such as halfway houses or home confinement, and in some cases into earlier transfer to supervised release. Federal regulations award 10 days of credit for every 30 days of successful participation in qualifying programs, with 5 additional days for people whose risk remains low or who show risk reduction over time. Thousands of prisoners have received earlier transfer to community settings after earned time credits were applied, according to Bureau of Prisons reports.

Not everyone qualifies. People convicted of certain offenses, including many violent crimes, some terrorism-related crimes, and some sex offenses, can't earn time credits, though other incentives such as additional telephone or visiting time still apply. The Sentencing Project and the Brennan Center estimate that more than half of the federal prison population falls into categories excluded from time credits because of offense-based restrictions and other limits.

Sentencing reforms in the act also reach thousands of federal defendants and prisoners. The law narrows enhanced drug penalties under 21 U.S.C. § 851, broadens the "safety valve" that lets judges sentence some low-level drug defendants below mandatory minimums, and ends prior "stacking" of 18 U.S.C. § 924(c) firearm counts for many cases. Notably, the act makes the Fair Sentencing Act of 2010 retroactive, so people with older crack cocaine convictions get a chance for resentencing under the newer, higher thresholds for crack quantities.

In the first year after enactment, the U.S. Sentencing Commission reported 2,387 sentence reductions under the retroactive crack provision alone. Average reductions came to 71 months, from 258 months down to 187 months. By the mid-2020s more than 4,000 people had received sentence reductions under this provision, separate from new cases sentenced under the updated rules.

Compassionate release also changed. Before 2018, the Bureau of Prisons controlled most motions for compassionate release under 18 U.S.C. § 3582(c)(1)(A). The First Step Act now allows prisoners to file motions directly in federal court after they finish internal requests. During the first year after enactment, courts granted 145 compassionate release motions, compared with 24 in 2018, and most successful motions came from people who filed on their own rather than from BOP requests. A later Sentencing Commission report on the COVID-19 period shows thousands of additional grants and confirms that judges, not BOP alone, now make most final decisions on compassionate release.

New rules on placement and conditions of confinement also matter. The law directs the Bureau of Prisons to try to place people within 500 driving miles of a primary residence when practicable, restrict restraints for pregnant prisoners, require free access to basic menstrual products, require new staff training on de-escalation and mental health, and limit solitary confinement for juveniles in federal custody. These measures shape daily life in federal facilities even for people whose sentence length doesn't change.

For you or your family, the most direct benefits come from a shorter stay in secure custody and an earlier move to reentry housing. A person with a long federal sentence and consistent program participation might see expanded good conduct time combined with earned time credits reduce prison time by months or more than a year. That reduction shifts into halfway house placement, home confinement, or supervised release, where work, family contact, and community support become easier to maintain.

Implementation and controversy

Implementation has moved much slower than many supporters expected and has drawn criticism from courts, advocates, and members of Congress. Oversight reports describe missed deadlines, data problems, and delays in applying benefits that Congress wrote into law.

The risk and needs assessment system saw the PATTERN tool released in 2019 within the statutory deadline, then revised in later updates. Independent researchers and advocacy groups have raised concerns about racial disparities in PATTERN scores and heavy weight on static criminal history factors. They've also pointed to limits from narrow eligibility rules and limited program capacity.

Earned time credits faced a major delay. The law took effect in December 2018, but the Bureau of Prisons didn't receive a final regulation on time credit calculation and application until January 2022. During that three-year stretch, the Bureau used interim procedures and manual calculations. Many prisoners reported uncertainty about time credit balances and about dates for transfer to halfway houses or home confinement. In 2023, the Government Accountability Office reported that the Bureau lacked complete and accurate data on assessments and program participation and hadn't set up full monitoring of whether staff completed assessments within required time frames, which affects eligibility to earn credits.

Delays and data problems have led to litigation and external pressure. Advocacy organizations such as Families Against Mandatory Minimums submitted comments criticizing the proposed time credit rule and later joined or supported lawsuits that allege miscalculation of credits and failure to move eligible people to community settings on time. News reports describe prisoners held past dates that defense lawyers and advocates calculate as correct under the statute and rule, often because staff don't apply credits to the date of enactment or because halfway house beds and home confinement slots remain limited.

Oversight hearings have become a tool for pressure. Members of Congress from both parties have used Senate and House Judiciary hearings and public letters to push the Department of Justice and the Bureau of Prisons on these issues. The Senate Judiciary Committee and House Judiciary subcommittees have held several hearings on First Step Act implementation, time credits, and prison conditions. In November 2022, Senators Richard Durbin and Charles Grassley sent a joint letter urging full implementation of earned time credits and stressing that eligible prisoners should receive earlier transfers and releases that Congress intended.

According to annual reports, the Department of Justice and the Bureau of Prisons say implementation work continues. They report expanded program lists, PATTERN revisions, guidance to staff on time credit calculation, and efforts to improve data systems. Still, the Department of Justice Office of the Inspector General identified First Step Act implementation, including accurate time credit application and consistent access to programs, as a significant management challenge in 2024.

For people in federal prison and families, the results are uneven. The First Step Act has shortened many sentences, expanded access to prerelease custody, and opened new routes to compassionate release. At the same time, offense exclusions, slow rulemaking, technology limits, and tight halfway house capacity have held back full access to benefits.
