The "Rehabilitation Access for Security Threat Group Members Act" aims to enhance access to rehabilitative programs for inmates classified as members of Security Threat Groups (STGs) within Texas correctional facilities. The bill mandates that the Texas Department of Criminal Justice (TDCJ) provide equal and unobstructed access to rehabilitative programs directly related to an inmate's crime of conviction, specifically for those convicted of drug or substance-related offenses. This includes programs focused on prevention, rehabilitation, and education regarding substance use. Importantly, the bill prohibits denying access to these programs based solely on an inmate's STG status, ensuring that all eligible inmates can participate without restrictions.

Additionally, the bill requires the TDCJ to establish an evaluation and reporting process within one year of its passage to monitor the effectiveness of the policy. This evaluation will include data on participation rates of STG members in relevant programs, the outcomes related to substance abuse reduction, and any barriers to access that may exist. The TDCJ is also tasked with submitting a report to the legislature every two years to detail the program's success and suggest any necessary adjustments. The act is set to take effect on September 1, 2025, and will apply to all individuals incarcerated during and after its passage.
