1. Get the official document

Official name: Time Review & Disposition form (CSX-482)

MDOC policy says a Time Review & Disposition form (CSX-482) is issued at least once a year to each prisoner eligible to earn good time (offenses before April 1, 1987), showing the parole board jurisdiction, minimum and maximum dates. For other prisoners we did not find an official name; ask the facility Record Office. [MDOC PD 03.01.100 (Good Time Credits)] (opens in new tab)

Official online lookup (some dates appear here): [MDOC Offender Tracking Information System (OTIS)] (opens in new tab)

2. Which credits should appear

• A prisoner subject to disciplinary time gets disciplinary time for each major misconduct they are found guilty of. [MCL 800.34 (disciplinary time)] (opens in new tab)
• Accumulated disciplinary time goes to the parole board for its parole review. The minimum sentence plus disciplinary time cannot exceed the maximum. [MCL 800.34 (disciplinary time)] (opens in new tab)
• Disciplinary time can be reduced for good behavior under the section's rules. [MCL 800.34 (disciplinary time)] (opens in new tab)

3. Common-errors checklist

• Jail (pretrial) credit: days spent in county jail before sentencing are missing or miscounted. Compare with the jail booking record and the judgment.
• Sentence start date: the computation begins on the wrong day.
• Concurrent vs. consecutive: the judgment says one thing and the computation does the other.
• Multiple cases: credit applied to the wrong case, or a case missing. Rules on splitting credit between cases vary by state.
• Earned credits not posted: months of work, school or programs, or completed certificates, do not appear.
• Losses and restorations: credits taken without a finished disciplinary hearing, or restored credits never added back.
• Wrong law version: credit rules applied from a different date than the offense date.
• Revocation time: time on parole or supervision handled differently than the rules say.
• Detainers or holds: another case or agency may keep the person past the computed date (see detainers).
• Typos: sentence length, number of counts, or dates copied wrong from the judgment.

Have ready: the judgment, jail booking records, program certificates and disciplinary decisions.

4. If you find an error

• Write to the records office naming the exact error, with copies (never originals).
• If it is not fixed, use the agency's official grievance or dispute process.
• If the error is in the judgment itself (for example jail credit), the court may need to correct it. Talk to a lawyer or the public defender.
