The Texas Department of Criminal Justice (TDCJ) is a state agency responsible for overseeing the management of prisons, parole, and probation in the state of Texas. It aims to ensure public safety by managing offenders and providing rehabilitation programs to reduce recidivism. TDCJ operates various facilities, including state prisons and community supervision programs. Additionally, TDCJ is involved in the administration of the death penalty in Texas, as the state is one of the few that still practices capital punishment. The agency also focuses on the health and well-being of inmates, offering medical and mental health services within its facilities.
