Federal RDAP: Eligibility, the Interview, and How the Time Off Is Actually Calculated
RDAP is the only Bureau of Prisons program that can take a year off a federal sentence. How much of that year you'll actually see was settled by the length of the sentence the judge handed down. And the paperwork that decides whether you qualify at all is usually written months before you're sentenced.
Twelve months is a ceiling, and BOP doesn't have to give you any of it. Under BOP Program Statement 5331.02 the reduction is capped at 6 months on a sentence of 30 months or less, 9 months from 31 to 36 months, and 12 months at 37 months or more.
What RDAP Is
The Residential Drug Abuse Treatment Program is authorized by 18 U.S.C. 3621(e), implemented at 28 CFR 550.53, and run under BOP Program Statements 5330.11, Psychology Treatment Programs, and 5331.02, Early Release Procedures Under 18 U.S.C. 3621(e), whose current change notice is dated May 7, 2026.
BOP describes it on its own substance abuse treatment page as its most intensive treatment program: cognitive behavioral therapy delivered in a modified therapeutic community, participants living in a unit separate from general population, half-day programming and half-day work, school or vocational activity, typically nine months in duration. Program Statement 5330.11 puts a floor under that description, a minimum of 500 contact hours across no less than nine months, with a program duration of 9 to 12 months.
The unit itself is regulated, and more tightly than people expect. Only those waiting for the program, participating in it, or who have completed it may live on the RDAP unit. Program Statement 5330.11 warns that any compromise of that unit purity invalidates early release eligibility for everyone housed there. Everyone. It is the sort of rule you want to hear about before you are living under it.
The U.S. Sentencing Commission summarizes the incentive the way the statute does: people convicted of nonviolent offenses who complete treatment in a facility set apart from the general population, and who comply with the other requirements, may earn up to one year off their term of imprisonment. Prisonpedia keeps a neutral overview at Residential Drug Abuse Program.
The Key Numbers

The Whole Program, Stage by Stage
Two different taxonomies get mixed together constantly. RDAP has three components under 28 CFR 550.53(a): the unit-based component, follow-up services, and Community Treatment Services, which BOP renamed from Transitional Drug Abuse Treatment. Inside the unit-based component there are three phases, set by Program Statement 5330.11: Orientation, Core Treatment and Transition. Pages that call the components "phases" are describing something else.
The table below runs the whole sequence, including the two screening steps that happen before anyone is admitted. Read the failure column first. That is where people actually lose this, and the losses cluster at the beginning and the end rather than anywhere in the middle.
| RDAP stage | Duration | What happens | Common failure point |
|---|---|---|---|
| Screening and verification | Before placement, no fixed length | A Drug Treatment Specialist reviews the Central File and the Pre-Sentence Report for documentation of a substance use disorder within the 12 months before arrest on the current offense, and confirms there is enough time left on the sentence. | Nothing in the PSR and no contemporaneous records from a provider, probation officer or detox. Recreational, social or occasional use that does not rise to excessive or abusive drinking is not verification. |
| Clinical interview with the DAPC | One interview, scheduled by proximity to release, ordinarily no less than 24 months out | The Drug Abuse Program Coordinator interviews you in person and forms a clinical judgment under DSM criteria. The documentation has to be consistent in time, intensity and duration with what you say about yourself. | The DAPC can find no diagnosis even where substantiating documentation exists. A self-report that does not match the paper is the usual reason. |
| Waiting list and placement | Varies by institution and demand | DSCC makes the initial designation. Coordinators monitor waiting lists so people transfer with enough time to finish the whole program, ordinarily at 24 months from release. People waiting on or next to the treatment unit follow RDAP unit rules. | Being designated somewhere that does not run RDAP. Breaking unit decorum while waiting draws a warning and then removal from the list, with a six-month wait before reapplying. |
| Phase I, Orientation | Ordinarily not more than 2 months | Psychosocial assessment conducted with you rather than by you, a treatment plan built from it, presentation of your case at a treatment team meeting, and a written progress report every 60 days after the plan is done. | Treating it as intake paperwork. The assessment is the beginning of an evaluation that does not stop until you leave. |
| Phase II, Core Treatment | Ordinarily not more than 5 months | Treatment journals and facilitator guides, daily group, progress reviews every 60 days, and staff observing participants on and off the unit, at work and on main line. | Behavior in group that does not match behavior on the compound. Staff are explicitly directed to compare the two. |
| Phase III, Transition | Ordinarily not more than 2 months | Practicing the skills and building realistic expectations for exiting the program. Phase testing is behavioral, and completion is judged on demonstrated behavior in the program and on the compound. | Coasting at the end. Inmates are not moved through a phase or completed until they demonstrate the expected behaviors, so completion is not a calendar event. |
| Follow-up treatment | 12 months, or until transfer to an RRC | Back in general population, monthly group of no less than 60 minutes, entered within the first month after returning to the unit. | Refusing follow-up is an RDAP failure and disqualifies you from the incentive after the hardest part is already done. |
| Community Treatment Services | Minimum 120 days in an RRC or on home confinement | Contracted community providers under BOP’s Community Reentry Affairs Branch. Completing this component is what makes completion of RDAP successful. | Approval for less than a 120-day RRC or home confinement placement. BOP changes the SENTRY assignment from eligible to ineligible when that happens. |

How the Time Off Is Actually Calculated
This is the part almost every page on the subject gets half right. The statute, at 18 U.S.C. 3621(e)(2)(B), says the period a person convicted of a nonviolent offense remains in custody after completing treatment "may be reduced by the Bureau of Prisons, but such reduction may not be more than one year." Read that twice. It sets a maximum, and it hands the Bureau the discretion to award less than the maximum or nothing at all.
The number that actually applies to you comes from Program Statement 5331.02, and it's keyed to the sentence the court imposed. How much time you have left doesn't enter into it.
| Sentence imposed | Maximum 3621(e) reduction | What that means in practice |
|---|---|---|
| 30 months or less | No more than 6 months | A 9-to-12-month program to buy six months. If you are set back a phase, or the RRC placement comes in short, the arithmetic can stop working. |
| 31 to 36 months | No more than 9 months | The policy states the time frames are not pro-rated by days. A sentence of 36 months and 30 days still caps at 9 months, not 9 months and a few days. |
| 37 months or more | No more than 12 months | The only bracket where the full statutory year is on the table. It is still a ceiling and still discretionary. |
Source: BOP Program Statement 5331.02, Change Notice CN-3, May 7, 2026, section 11.
Three things the bracket table does not tell you
The reduction is not credited when you finish the unit-based program. It follows completion of community treatment. Until then the 3621(e) date is provisional, and BOP requires a final unit team review, ordinarily 30 days before transfer to a residential reentry center, to confirm every criterion has been met. Families plan around that provisional date constantly. It has not hardened yet. How that transfer and the prerelease placement behind it get decided is covered in the halfway house and home confinement guide.
A court-ordered sentence reduction recalculates the incentive. Program Statement 5331.02 gives the example: a 36-month sentence reduced to 24 months results in no more than a 6-month early release. Winning a Rule 35 or a 3582 reduction can cost you three months of RDAP benefit at the same time.
Good conduct time is applied first. BOP says so in its First Step Act FAQ: the projected release date is first adjusted for the good conduct time changes, and then BOP reviews inmates participating in RDAP to determine the appropriate sentence reduction. The order matters. People assume the two stack. They run one after the other.
One correction worth making, because it circulates widely: twelve months under 3621(e) plus a long halfway house placement does not add up to an eighteen-month sentence reduction. Time in a residential reentry center or on home confinement is still service of the sentence in BOP custody. If you're modeling a release date, keep the RDAP reduction and the prerelease placement on two separate lines. More on the second one is on sentence reduction.
Who Qualifies for the Program
Qualifying for RDAP and qualifying for the sentence reduction are two separate tests, and blurring them is the single most common error in this subject. Program Statement 5330.11 states it flatly: inmates with a diagnosis of a substance use disorder are qualified for the RDAP whether or not they are eligible for the early release incentive.
Admission itself, under 28 CFR 550.53(b), is three things. A verifiable substance use disorder. A signed agreement acknowledging program responsibility. And the ability, when beginning the program, to complete all three components. Program Statement 5330.11 adds the operational screen that an applicant ordinarily has 24 months or more remaining on the sentence, which is why timing and designation matter as much as the diagnosis. Applications go to a staff member, ordinarily the unit team or the Drug Abuse Program Coordinator, after arrival.
What counts as verification
The Pre-Sentence Report is the most convenient source of documentation. It is far from the only one. Program Statement 5330.11 lists the collateral documentation a Drug Treatment Specialist may rely on:
- Documentation supporting a substance use disorder within the 12-month period before arrest on the current offense.
- Documentation from a probation officer, parole officer or social services professional who has information verifying the problem within that same window.
- Documentation from a substance abuse treatment provider or medical provider who diagnosed and treated you within that window.
- Two or more convictions for driving under the influence or driving while intoxicated in the five years before your most recent arrest.
The policy adds a limit that catches people out. Recreational, social or occasional use that doesn't rise to the level of excessive or abusive drinking won't provide the required verification. Documentation has to indicate problematic use consistent with DSM criteria. A few heavy years in your thirties that nobody wrote down is a story rather than a record, and the file is what gets read.
If the PSR says nothing about substance use
This is a real problem and it's survivable, which is worth saying plainly because a lot of pages imply otherwise. When there is no verifying documentation in the PSR or the Central File, the specialist is required to meet with you and put a specific set of options in front of you: volunteer for the non-residential drug abuse program; obtain records from a treatment provider you saw previously, written at the time services were provided and showing a diagnosis was made then; obtain documentation from a probation officer, parole officer or social services professional; consent to a medical examination for physical evidence of use; or verify a detoxification you received on entry into BOP custody. Records have to go directly to institution treatment staff. Nobody is going to let you carry them in yourself.
There is also one statutory carve-out almost nobody writes about. 18 U.S.C. 3621(e)(7), added in March 2022, bars the Director of the Bureau of Prisons from prohibiting an eligible prisoner who is a primary caretaker parent or pregnant from participating in RDAP on the basis of a failure, before being committed to BOP custody, to disclose a substance abuse problem.
All of that said, the cheapest version of this problem is the one solved before the report is final. What goes into the PSR, and how the probation officer characterizes it, is the piece of pre-sentencing work that pays for itself here. See the pre-sentence investigation for how that interview actually runs.
Immigration detainers work differently than people are told
The usual line is that a detainer costs you the sentence reduction. The real effect is bigger. Because 28 CFR 550.53(b)(3) requires the ability to complete all three components, and the third component happens in the community, someone who cannot be placed in a residential reentry center cannot complete RDAP at all. Program Statement 5330.11 gives exactly this example and calls a deportable inmate unqualified for the RDAP, with the non-residential program available instead. One nuance in the other direction: if you are already qualified and in treatment when a detainer is lodged, the policy allows you to remain in the program.
The RDAP Interview
There are two gates and they run in order. First a Drug Treatment Specialist reviews your Central File and collateral sources to see whether documentation of a substance use disorder exists. Only if verifying documentation is found or produced are you personally interviewed by the Drug Abuse Program Coordinator. Interviews are scheduled by proximity to release, ordinarily no less than 24 months out, which is why people who arrive with five years to serve wait a long time before anything happens.
The interview itself is a clinical one. The coordinator uses psychological training to form a judgment about whether you have a substance use diagnosis under DSM criteria. The sentence in the policy that decides most outcomes is this: all verifying documentation used is to be consistent in time, intensity and duration with the inmate's self-report. That's the mechanism, and it explains both of the ways people actually fail this.
Overstate it and the paper contradicts you. A file showing one documented episode won't support an account of daily use across a decade, and the mismatch itself becomes the finding. Understate it, out of pride or a lawyer's caution about admitting anything, and you've left the coordinator nothing to diagnose. Note the policy is explicit on one more point: the coordinator may find no diagnosis even where substantiating documentation exists. A clean file gets you the interview. It doesn't decide it.
The coordinator is also assessing something separate from your history: whether you can participate at all. Cognitive impairment, a severe learning disability, or an inability to participate in the language the program is conducted in can each mean no, independent of the diagnosis.
Two forms come out of a yes. The Agreement to Participate in the Bureau of Prisons Residential Drug Abuse Treatment Program, BP-A0749, and, where your supervised release conditions do not already include a treatment stipulation, a waiver of hearing to modify the court order. That second one surprises people. Completing RDAP can mean agreeing to a modification of the judgment in your case.
Sam Mangel's read on the room, from having sat with clients on both sides of it: people walk in treating the interview as a pitch, and that is the fastest way to fail it. The ones who do well have a history that's documented, an account of it that matches the documentation, and nothing rehearsed. The honest answer about whether you qualify is also the only answer that survives contact with your own file. That holds whether or not it's the answer you were hoping for.
What Disqualifies You From the Year
Nearly all of the exclusions people talk about bar you from the 3621(e) sentence reduction. Very few of them bar you from treatment. The list lives at 28 CFR 550.55(b), and it is framed as an exercise of the Director's discretion rather than a statutory bar.
| Disqualifier | Source | Bars the program or the reduction? | The nuance |
|---|---|---|---|
| ICE detainee, or anyone ineligible for RRC placement | 28 CFR 550.55(b)(1) and 550.53(b)(3) | Both | A person who cannot go to an RRC cannot complete Community Treatment Services, so BOP treats them as unqualified for RDAP itself. Policy gives the example directly. If the detainer is lodged after someone is already in treatment, they may remain in the program. |
| Pretrial inmate or contractual boarder | 28 CFR 550.55(b)(2) and (b)(3) | The 3621(e) reduction | State and military inmates housed under contract are in this category. |
| Prior conviction for homicide, forcible rape, robbery, aggravated assault, arson, kidnapping, or sexual abuse of minors | 28 CFR 550.55(b)(4) | The 3621(e) reduction | Only if the conviction falls within the ten years before the date of sentencing on the current case. That ten-year window came in with the 2016 amendment and most sites still describe the exclusion as permanent. |
| Current felony with a force element, or involving a firearm, dangerous weapon or explosives | 28 CFR 550.55(b)(5), PS 5162.06 section 4 | The 3621(e) reduction | A two-level Specific Offense Characteristic enhancement for possessing a dangerous weapon during a drug offense is enough on its own, per the worked example in the program statement. |
| Attempt, conspiracy or solicitation of any of the above | 28 CFR 550.55(b)(6), PS 5162.06 section 3.c | The 3621(e) reduction | Staff read the underlying offense out of the PSR. A conspiracy count is only as violent as what was being planned. |
| A prior 18 U.S.C. 3621(e) early release | 28 CFR 550.55(b)(7) | The 3621(e) reduction | Once in a lifetime, regardless of how the second sentence reads. |
| Expulsion, withdrawal, or refusing follow-up or community treatment | 28 CFR 550.53(g) and (h), 550.56(a) | The 3621(e) reduction | It also costs furloughs, above-maintenance performance pay and UNICOR eligibility, and BOP counts refusal, withdrawal and expulsion as a factor in setting the length of community confinement. |
Sources: 28 CFR 550.55, 28 CFR 550.53, and BOP Program Statement 5162.06, Categorization of Offenses, March 19, 2026.
The ten-year window
The prior-conviction exclusion at 550.55(b)(4) is the one most often reported wrong. It reaches convictions "within the ten years prior to the date of sentencing" on the current case. That window arrived with an amendment published at 81 FR 24490 on April 26, 2016, and a great deal of the material still circulating online, including encyclopedia summaries, describes the exclusion as if any prior conviction of that type is permanent. Read the date of whatever you are reading.
Where white-collar cases actually land
The document the Designation and Sentence Computation Center applies to your offense is Program Statement 5162.06, Categorization of Offenses, dated March 19, 2026. It rescinded the 2009 version outright, and most competing pages still cite the rescinded one. Three points matter for the offenses Sam Mangel's clients are usually convicted of.
Mail fraud at 18 U.S.C. 1341, wire fraud at 1343 and bank fraud at 1344 do not appear anywhere in that program statement. Money laundering at 1956 and racketeering at 1962 do, on the section 4.c list of offenses that may preclude program benefits, which requires staff to examine the entire Offense Computation section of the PSR and, where necessary, the Offense Conduct section. Racketeering is worse off than that summary suggests: 1962 is also listed in section 3.c, among the offenses that may be categorized as crimes of violence depending on what the underlying conduct was. A RICO count is read through to what was actually charged underneath it. All offenses under 18 U.S.C. 922(g) preclude, without a review and without exception.
The weapons trigger is broader than a gun charge. The program statement's own worked example is a defendant convicted under 21 U.S.C. 841 who received a two-level Specific Offense Characteristic enhancement for possessing a dangerous weapon during the offense. That enhancement alone is enough to preclude the benefit.
This is a document-by-document determination made by DSCC legal staff, who ordinarily have 30 working days to complete the offense review after receiving the request and the judgment and commitment file. Nobody can promise you the outcome of that review before it happens. What can be done is making sure the record they read says what actually happened. That work sits alongside early release eligibility.
What Happens If You Are Expelled
Removal is the Drug Abuse Program Coordinator's decision, for disruptive behavior related to the program or unsatisfactory progress in treatment. Ordinarily there is at least one formal warning first, along with a documented treatment intervention: a meeting about the behavior, an assigned intervention, a warning about consequences, and an amended treatment plan signed by both staff and inmate. The warning requirement is waived when the noncompliance is serious enough that the person's continued presence would create an immediate and ongoing problem for staff and other inmates.
Removal is immediate, with no intervention, if the Discipline Hearing Officer finds a prohibited act involving alcohol or drugs, violence or threats of violence, escape or attempted escape, or any 100-level series incident. Violating group confidentiality can also end participation without a formal intervention. Within two working days of a decision to expel, the coordinator notifies you verbally and in writing, updates the SENTRY drug program assignments, and documents the expulsion.
For someone who was early-release eligible, the consequence is mechanical. The SENTRY assignment is changed from eligible to ineligible, the Change in RDAP and 3621(e) Status form goes to the unit team and DSCC, and the sentence computation is redone. If the DHO later finds you not guilty of the underlying misconduct, the coordinator convenes the treatment staff to decide whether you can be reinstated.
Withdrawal and an incomplete are two different things. Placement in the Special Housing Unit, removal on a writ, or an unforeseen redesignation can all move someone to incomplete status, and policy states an incomplete does not automatically make the inmate a failure. The treatment team decides based on the reason.
You can come back. An inmate who declined, withdrew or failed may reapply after 90 days through an Inmate Request to Staff form, with the treatment team deciding on readmission. The catch is in the same paragraph: if readmitted, to the same RDAP or a different one, the inmate receives no credit for prior treatment participation. On a 30-month sentence, where the reduction caps at six months anyway, there's almost no room left for a second run at a nine-to-twelve-month program. Do that arithmetic before you take the risk. A separate rule covers people removed from the waiting list for unit conduct before they ever start: six months before they can formally reapply.
RDAP, First Step Act Credits and Good Conduct Time
Five different mechanisms move a federal release date, and they don't do the same job. Two shorten the sentence. Two change where the last stretch is served. One buys prerelease custody without shortening anything. Confusing them is how people arrive at release dates that are months off.
| Mechanism | Maximum | What it actually does | Source |
|---|---|---|---|
| Good conduct time | Up to 54 days per year of the sentence imposed | Shortens the term. Applied first, before the RDAP reduction is reviewed. | 18 U.S.C. 3624(b)(1) |
| RDAP sentence reduction | Up to 12 months, bracketed by sentence length | Shortens the term. Credited on completion of community treatment, not at the end of the unit-based program. | 18 U.S.C. 3621(e)(2)(B), PS 5331.02 |
| First Step Act time credits | 10 days per 30 days of participation, plus 5 more for minimum or low risk sustained across two assessments | Does not shorten the term. Buys prerelease custody, or moves the start of supervised release up to 12 months earlier. | 18 U.S.C. 3632(d)(4), 3624(g) |
| Residential reentry center placement | Up to 12 months | Changes where the end of the sentence is served, not how long it is. | 18 U.S.C. 3624(c)(1) |
| Home confinement | The shorter of 10 percent of the term or 6 months | Changes where the end of the sentence is served. This is the provision most often confused with the 12-month RRC ceiling. | 18 U.S.C. 3624(c)(2) |
Sources: 18 U.S.C. 3624, 18 U.S.C. 3621, and BOP's First Step Act FAQ.
RDAP was not changed by the First Step Act. BOP says that in one sentence in its FAQ, and it settles a long-running argument. The 2018 law amended other subsections of 3621; it left the 3621(e) incentive alone.
RDAP still earns First Step Act credits. It is listed as an evidence-based recidivism reduction program in BOP's First Step Act Approved Programs Guide, which is what makes participation credit-earning. The two benefits run on separate tracks from the same nine to twelve months of work.
Being expelled can cost you twice. Losing RDAP costs the 3621(e) reduction. Because RDAP is an EBRR program, violating its rules also puts earned time credits at risk under the FSA framework, and BOP handles restoration through a program review after two consecutive assessments with clear conduct.
Declining after you are accepted has a specific price. BOP's FAQ states that where an inmate refuses or declines to participate in a recommended EBRR program or productive activity they had been waitlisted for, the credits earned while on the waitlist are rescinded. People trade this as rumor. It's written down.
The full treatment of the credit system is at the First Step Act, and the halfway house mechanism sits in the Second Chance Act.
If the person going in is a woman, some of this lands differently. BOP runs five Female Integrated Treatment programs, at SCP Greenville, SCP Danbury, FCI Tallahassee, FMC Carswell and SCP Phoenix, and its Approved Programs Guide states that women with substance use disorders who qualify for RDAP can complete it inside the FIT program, in a trauma-informed modified therapeutic community, and may be eligible for the associated early release benefit. Once you've read the above, womensfederalprison.com has a longer treatment of RDAP and First Step Act credits for women that is worth the time.
Where RDAP Is Offered, and Why Designation Decides It
Not every federal institution runs RDAP, and the roster moves. The current one is published by region in BOP's First Step Act Approved Programs Guide, dated May 2026, which counts 57 RDAPs at 50 locations plus five Female Integrated Treatment programs. The camps and low-security institutions where most white-collar defendants are designated are well represented on it: FPC Alderson, FPC Yankton, FPC Bryan, FPC Montgomery, SCP Cumberland, SCP Leavenworth, SCP Lewisburg, SCP McKean, SCP Texarkana, SCP Edgefield, FSL Jesup, FCI Allenwood, FCI Danbury, FCI Fort Dix, FCI Schuylkill, FCI Englewood and FCI Miami. The Female Integrated Treatment programs, at SCP Greenville, SCP Danbury, FCI Tallahassee, FMC Carswell and SCP Phoenix, each include an RDAP component.
Worth knowing if you are checking this yourself: BOP publishes a second, standalone RDAP locations list, linked from its substance abuse treatment page, and the two documents do not agree. That list is dated January 2025 and counts 65 RDAPs at 53 locations. It still carries FPC Duluth and FPC Pensacola, both flagged as closing, and neither of them appears on the May 2026 roster. It also flags programs that are suspended rather than closed, which the guide does not.
The direction of travel is worth stating plainly, because nobody selling you anything will: 81 programs at 71 locations on BOP's June 2021 list, 65 at 53 in January 2025, 57 at 50 in the current guide. RDAP capacity is contracting, which is what turns designation from a preference into the thing the whole benefit hangs on. Check the date on whichever list you are reading, and check it again before you rely on it.
The initial designation is made by the Designation and Sentence Computation Center in Grand Prairie, Texas. Coordinators then monitor waiting lists to make sure people transfer with enough time to finish the entire program before release, ordinarily at 24 months. Policy also warns that you may be transferred to any suitable BOP RDAP based on your release date, and that notification is built into the agreement you sign. Landing somewhere you like buys you nothing permanent. You can be moved.
A judicial recommendation is a recommendation. The judge can put RDAP and a preferred institution in the judgment, and it carries weight, but BOP designates. What Sam Mangel does here is advocate for a designation to a facility that actually runs the program with capacity in your window, and make sure the record supporting that request is in front of the people who decide. He doesn't place anyone anywhere, and neither does anyone else outside BOP.
Prisonpedia's background on security levels and camp placement is at Federal Prison Camp. On this site, the designation work itself is facility designation, and the sequence from sentencing to report date is in the self-surrender timeline.
What Sam Mangel Does on an RDAP Case
Before sentencing. Making sure a real substance use history is documented accurately and verifiably while the Pre-Sentence Report is still being written, and that the judicial recommendation asks for the right thing rather than a generic nod at treatment. This is the cheapest hour on the whole timeline and the one people most often skip.
At designation. Advocating for a facility that runs RDAP with capacity in your release window, and building the request around what BOP actually weighs.
In the program. Understanding what completion is measured on, what a set-back phase costs against your release date, and how the community treatment placement has to be sized so the whole thing counts.
What nobody can do: promise the coordinator's clinical judgment, promise the outcome of DSCC's offense review, or promise a bed date. Those are BOP's, and any consultant who tells you otherwise is selling something. What can be done is arriving at each of those decisions with the strongest honest record, and knowing in advance which of them is going to be the hard one in your case. That part is worth a phone call.
RDAP Questions People Actually Ask
What qualifies you for RDAP?
28 CFR 550.53(b) sets three admission criteria: a verifiable substance use disorder, a signed agreement acknowledging program responsibility, and the ability at the start of the program to complete all three components. BOP Program Statement 5330.11 adds an operational screen, that an applicant ordinarily has 24 months or more remaining on the sentence. A substance use disorder is verified through documentation, and the Pre-Sentence Report is only one of the accepted sources. Records from a treatment provider or medical provider written at the time of service, documentation from a probation officer, parole officer or social services professional, and two or more DUI or DWI convictions in the five years before the most recent arrest all count.
What disqualifies you from RDAP?
Almost nothing disqualifies you from the program itself. Program Statement 5330.11 states that inmates with a diagnosis of a substance use disorder are qualified for RDAP whether or not they are eligible for the early release incentive. What is restricted is the 18 U.S.C. 3621(e) sentence reduction. Under 28 CFR 550.55(b), that is unavailable to ICE detainees, pretrial inmates, contractual boarders, anyone with a prior homicide, forcible rape, robbery, aggravated assault, arson, kidnapping or sexual-abuse-of-minors conviction within the ten years before the date of sentencing, anyone whose current felony has a force element or involved a firearm, dangerous weapon or explosives, and anyone who has already received a 3621(e) release once. The one exception that also blocks the program is an inability to complete community treatment, which is why an immigration detainer can make someone unqualified for RDAP itself.
How much time does RDAP take off your sentence?
18 U.S.C. 3621(e)(2)(B) caps the reduction at one year and makes it discretionary rather than automatic. Program Statement 5331.02 sets the bracket by the sentence the court imposed: 30 months or less, no more than 6 months; 31 to 36 months, no more than 9 months; 37 months or more, no more than 12 months. The policy states that these time frames are not pro-rated by days, so a sentence of 36 months and 30 days still caps at 9 months. If the court later reduces the sentence, the incentive is recalculated. The reduction is not credited at the end of the unit-based program; it follows completion of community treatment.
How long does RDAP take?
Program Statement 5330.11 states the RDAP is a minimum of 500 hours with a duration of 9 to 12 months, delivered as half-day programming over no less than nine months. BOP’s public program page describes RDAP as typically nine months. The unit-based component is followed by 12 months of follow-up treatment in general population, or until transfer to a residential reentry center, and then Community Treatment Services in the community, which cannot ordinarily be completed in less than 120 days.
What if my PSR does not mention substance abuse?
It is a problem, not a dead end, and the policy says so. When there is no verifying documentation in the Pre-Sentence Report or the Central File, Program Statement 5330.11 requires the Drug Treatment Specialist to meet with the inmate and offer a specific set of options: volunteering for the non-residential drug abuse program, obtaining records from a prior treatment provider that were written at the time services were provided, obtaining documentation from a probation officer, parole officer or social services professional, consenting to a medical examination for physical evidence of use, or verifying a detoxification received on entry into BOP custody. Documentation must be sent directly to institution drug abuse treatment staff, not routed through the inmate. Separately, 18 U.S.C. 3621(e)(7) bars BOP from excluding a primary caretaker parent or a pregnant person from RDAP for having failed to disclose a substance abuse problem before entering custody.
Can I still do RDAP if I have a violent offense?
Usually yes for the program, and usually no for the sentence reduction. The exclusions in 28 CFR 550.55(b) are written as limits on early release eligibility, not on treatment. Program Statement 5330.11 is explicit that a substance use diagnosis qualifies someone for RDAP whether or not the early release incentive is available. Completing the program still carries other incentives under 28 CFR 550.54, including consideration for the maximum period of community-based treatment.
Can you do RDAP twice?
You can be readmitted, but the accounting resets. Program Statement 5330.11 allows an inmate who declined, withdrew or failed RDAP to reapply after 90 days through an Inmate Request to Staff form, with the treatment team deciding on readmission. If readmitted to the same or a different RDAP, the inmate receives no credit for prior treatment participation and starts over. Separately, 28 CFR 550.55(b)(7) makes anyone who has already received a 3621(e) early release ineligible to receive a second one.
Which federal prisons have RDAP?
The current roster is published by region in BOP’s First Step Act Approved Programs Guide, dated May 2026, which counts 57 RDAPs at 50 locations plus 5 Female Integrated Treatment programs. Camps and low-security institutions on it include FPC Alderson, FPC Yankton, FPC Bryan, FPC Montgomery, SCP Cumberland, SCP Leavenworth, SCP Lewisburg, SCP McKean, SCP Texarkana, SCP Edgefield, FSL Jesup, FCI Allenwood, FCI Danbury, FCI Fort Dix, FCI Schuylkill, FCI Englewood and FCI Miami, plus the five FIT programs at SCP Greenville, SCP Danbury, FCI Tallahassee, FMC Carswell and SCP Phoenix that each include an RDAP component. BOP also keeps a separate standalone RDAP locations list, linked from its substance abuse treatment page, and the two documents do not agree. That list is dated January 2025 and counts 65 RDAPs at 53 locations, and it still carries FPC Duluth and FPC Pensacola, both flagged as closing and neither of them on the May 2026 roster. Check the date on whichever list you are reading. Designation itself is BOP’s decision, made by the Designation and Sentence Computation Center. A judicial recommendation is a recommendation, not an assignment.
What happens if you get kicked out of RDAP?
The Drug Abuse Program Coordinator can remove someone for disruptive behavior related to the program or unsatisfactory progress in treatment, and under 28 CFR 550.53(g) there is ordinarily at least one formal warning first. That warning is waived where the conduct is serious enough that the person’s continued presence would create an immediate and ongoing problem. Removal is immediate, with no intervention, if the Discipline Hearing Officer finds a prohibited act involving alcohol or drugs, violence or threats of violence, escape, or any 100-level series incident. Violating group confidentiality can also mean expulsion without a formal intervention. The SENTRY assignment flips from eligible to ineligible and the release date is recomputed. If the DHO later finds the person not guilty, the treatment team can consider reinstatement.
Does RDAP stack with First Step Act credits and good conduct time?
Yes, and BOP states the order. Its First Step Act FAQ says the RDAP was not changed by the FSA, and that a projected release date is first adjusted for the good conduct time changes, after which BOP reviews participating inmates to determine the appropriate RDAP sentence reduction. Good conduct time is up to 54 days per year of the sentence imposed by the court under 18 U.S.C. 3624(b). RDAP is separately listed as an evidence-based recidivism reduction program in BOP’s First Step Act Approved Programs Guide, so participation also earns federal time credits, which buy prerelease custody or an earlier start to supervised release rather than shortening the sentence itself.
Find Out Where You Actually Stand on RDAP
Two decisions are usually still open when people call. Whether the substance use history is documented well enough, and early enough, to survive the verification review. And whether the designation request is pointed at an institution that runs the program with room in your window. Sam Mangel will tell you which one is the real problem in your case, including when the answer is that RDAP is not worth the nine to twelve months.
