How the RDAP Sentence Reduction Works and How to Keep It After Completion

After someone successfully completes RDAP, what is the process for actually getting the sentence reduction applied and are there any ways that benefit can still be lost after completion?

Completing RDAP is a significant achievement but understanding how the benefit actually works will help you protect it all the way through to release.

Here is the complete picture.

The Basic Qualifications

To qualify for the full 12 month sentence reduction you must have a sentence of at least 37 months. The program itself takes 9 months to complete. The BOP tries to get eligible inmates into the program with roughly 9 to 10 months remaining on their sentence, though there is usually a waiting list so planning ahead matters.

The Sentence Reduction

Successful completion reduces your sentence by up to 12 months. But the reduction is only one part of the benefit.

The Halfway House Advantage

This is the part most people do not know about and it is just as valuable as the sentence reduction itself.

Standard federal inmates may receive as little as 2 months of halfway house time before their release date. RDAP graduates are entitled to a minimum of 6 months of halfway house time. That difference of 4 additional months outside the prison walls, in a halfway house with far more freedom than any federal facility, is a hidden gift that most defendants and their attorneys never factor into the decision to pursue RDAP qualification.

Halfway house is not prison. You have significantly more freedom, more access to your family, and the ability to start rebuilding your life in a real environment rather than behind a wall.

After Completion — The Waiting Period

Once you finish the 9 month residential program you do not necessarily go directly to the halfway house. Some inmates transfer immediately. Others wait months before their release date arrives. During that waiting period your behavior record must remain completely clean. Any infraction during that window puts your sentence reduction and your halfway house eligibility at risk. Every day between completion and release requires the same discipline as the program itself.

RDAP Becomes TDAT on the Outside

Once you arrive at the halfway house the program does not end. It transitions into what is called Transitional Drug Abuse Treatment, known as TDAT. This is the community based follow up phase of RDAP and participation is mandatory.

TDAT requirements typically include attending three meetings per week, submitting to random drug testing, and maintaining compliance with all halfway house rules and conditions. The structure is significantly less restrictive than the residential phase but the consequences of non-compliance are serious.

How You Can Still Lose the Benefit After Completion

This is the part that catches people off guard. Even after you have a certificate of RDAP completion in your hand, the sentence reduction can still be taken away.

If you fail to comply with TDAT requirements at the halfway house, if you fail a drug test, miss meetings, or violate halfway house conditions, the BOP can revoke your sentence reduction. The certificate of completion covers the residential phase only. The full benefit is not secured until you have completed the entire continuum, including the transitional phase on the outside.

Treat TDAT with the same seriousness as the program inside. You are months away from full release. Do not lose 12 months of your life in the final stretch.
