What Does Unaudited Mean in Prison Terms: FSA Credits and PATTERN

In federal prison records, an “unaudited” release date is a projected date that corrections staff have not yet manually verified. The number comes out of an automatic calculation: the sentence the judge imposed, minus the maximum good-conduct credit the inmate could earn with perfect behavior. No one has sat down with the case file and checked that every input is correct. Until that review happens, the date can move earlier or later.

Where You See This Label

Most people run into the word on the Bureau of Prisons inmate locator or a similar state corrections site. The release date shown there is generated by the system, not confirmed by a person. It assumes the inmate will earn every day of good-conduct time available and that nothing in the underlying sentence computation needs correcting. The BOP treats the public page as informational, not authoritative.

The authoritative document is the Sentence Computation Data sheet kept at the facility where the inmate is housed.¹ It lays out the court of jurisdiction, the sentence imposed, credit for prior custody, good-conduct time awarded or disallowed, and the projected release date that results. If the public website and the internal computation disagree, the internal computation controls.

What a Sentence Audit Actually Checks

An audit is a manual walk-through of every piece of the calculation. The BOP follows Program Statement 5880.28 for sentences under the Comprehensive Crime Control Act of 1984.² Correctional Systems staff verify:

Prior custody credit. Federal law requires credit for time spent in official detention before the sentence began, provided that time hasn’t already been credited to another sentence. If the inmate claims days not reflected in U.S. Marshals Service paperwork, staff must contact the arresting agency to confirm.³²
Good-conduct time. On each anniversary date, staff review the disciplinary log before awarding credit. Both the calculation and the log review must be signed and dated by the staff member and an auditor.²
Sentence structure. Staff confirm whether sentences run concurrently or consecutively, whether detainers from other jurisdictions affect the computation, and whether any court orders have modified the original sentence.

Audits happen at several points: an initial audit when the inmate arrives at a designated facility, periodic reviews during incarceration, and a pre-release audit before the inmate goes home.² That is where most errors surface. A date that looked firm for years can shift once someone traces every credit and deduction by hand.

Why Good-Conduct Time Makes the Date Optimistic

Good-conduct time is the main reason an unaudited date is unreliable. Under federal law, an inmate serving more than one year can earn up to 54 days of credit for each year of the sentence imposed, if the BOP finds they showed exemplary compliance with institutional rules during that period.⁴

The public release date usually assumes the inmate will earn the full 54 days every year. That assumption only holds if behavior stays clean. A disciplinary infraction can cost some or all of a year’s credit and push the date later.⁴ The BOP also factors in whether the inmate is working toward a GED or high school diploma when deciding how much credit to award. Partial final years are prorated.⁵ None of that detail appears on the public locator. The number you see is the best-case endpoint, and until an auditor confirms the disciplinary record and credit awards, it stays unaudited.

First Step Act Credits and PATTERN Keep the Date Moving

Separate from good-conduct time, the First Step Act created time credits for inmates who participate in approved programs. An eligible inmate earns 10 days of credit for every 30 days of successful participation in recidivism reduction programming or productive activities. Inmates classified as minimum or low risk who maintain that classification over two consecutive assessments earn an additional 5 days per 30-day period, for a total of 15.⁶ These credits apply toward time in prerelease custody or supervised release rather than coming straight off the sentence.

For anyone watching the public page, the catch is that First Step Act credits are not always reflected right away. They get applied only after BOP review and approval. The date on the locator may not account for them at all until the computation is formally audited.

Eligibility for the bonus 5 days depends on the inmate’s risk classification under PATTERN, the BOP’s risk and needs assessment tool.⁷ PATTERN reassessments run on a set schedule: every 180 days for most inmates, and every 90 days once an inmate is within 12 months of their projected release date.⁸ Each reassessment can change the classification, which changes how many credits the inmate earns from that point forward. Because those results feed directly back into the sentence computation, the projected date keeps moving until the pre-release audit locks it in.

Getting the Real Number

The most reliable figure is the one on the Sentence Computation Data sheet from the inmate’s unit team at the facility. The inmate or their attorney can request it. Specific details like prior custody periods and arrest history are not public and are released only through a written request with an original signed authorization form from the inmate; faxed or copied forms are not accepted.¹

If the computation looks wrong, the inmate should raise it with Correctional Systems staff first. Many questions get resolved informally once staff pull the data and walk through the math. If that doesn’t fix the problem, the inmate can file a formal grievance through the BOP’s Administrative Remedy Program, which runs from the warden to the Regional Director to the General Counsel.⁹ Federal courts generally require all three levels to be exhausted before an inmate can sue over a sentence computation.

For families, the practical takeaway is simple. A date labeled unaudited is the system telling you the math has not been checked. Treat it as a rough estimate, not a promise. As the pre-release audit approaches, the number firms up. Until then, expect it to move.
