Defendants contemplating a plea bargain deal for prison time need to know how much time they will actually serve before being eligible for parole. One key component to understanding your parole eligibility calculation is the “good time credits” awarded by TDCJ. When doing ball park eligibility calculations, family members sometimes rely on the general rule of thumb that if the inmate doesn’t get in trouble, he gets one day of good time credit for each “calendar” day he serves (Inmates normally refer to calendar as “flat time”).
But the actual rules are more complicated. Although you certainly don’t need to understand every nuance in the law, a general grasp of what good time you can earn (and what can be taken away) is important when planning for a post-prison future.
The first thing to know is that the statutory framework for awarding good time is hard to understand if you don’t already have knowledge of how TDCJ classification works. For anyone sentenced on or after September 1, 1987 (referred to awkwardly in the system as “70th Legislature offenders”) you earn a certain amount of days of good conduct time per 30 days calendar time served. The specific number of days you can earn depends on your classification. For example, if you’re designated as “Line CLass I” you can earn a maximum of 20 days per 30-day period. In addition, the statue authorizes TDCJ to award a “Line Class 1” inmate 15 days of work time credit. So, if you start out classified as Line Class 1, get a job and keep it, and don’t get in administrative trouble, you’ll bet cruising along earning 65 days total credit for each 30-day period – 30 days flat time, 20 days good time, and 15 days work time.
