Relating to the award of good conduct time to inmates.

This bill clarifies that good conduct time (GCT) in Texas only affects eligibility for parole or mandatory supervision under specific statutes (Sections 508.145/508.147), not an inmate's total sentence length. It states GCT is a privilege, not a right, and requires inmates to either: (1) actively participate in approved programs (agricultural, vocational, educational, industrial, or treatment), or (2) regularly attend religious services or study religious texts. The law applies to all inmates confined in Texas Department of Criminal Justice facilities starting September 1, 2025, regardless of when their offense occurred. It does not change existing GCT calculation methods but explicitly defines its limited scope and eligibility criteria.
