S.B. No. 1388 amends the Health and Safety Code to enhance family support services under the Thriving Texas Families Program, which is a continuation of the alternatives to abortion program. The bill introduces new definitions, including "abortion services provider," which encompasses various roles related to abortion services, and "network contractor," referring to those who contract with the commission to provide services. It also establishes that service providers must not be associated with abortion services and must certify their compliance with the program's life-affirming mission. Additionally, the bill expands the types of services offered, including housing assistance and educational resources, while explicitly prohibiting the use of program funds for any abortion-related services.

The legislation further stipulates that organizations eligible for funding must not have any affiliations with abortion services providers and outlines specific criteria for disqualification. It also includes provisions to facilitate participation by smaller service providers with annual revenues under $2 million, aiming to simplify their application and compliance processes. The bill mandates the Health and Human Services Commission to adopt necessary rules for implementation, with an effective date set for September 1, 2025.
