SB 661 establishes the Office of Youth Health and Safety under the Texas government, with the goal of promoting trauma-responsive and culturally informed services for juveniles in the justice system. It creates a 21-member board, tasked with developing a plan to end commitments of children to secure correctional facilities by 2028, reduce current juvenile detention populations, and establish alternative infrastructure and services for delinquency prevention. The plan also seeks to eliminate racial and disability disparities in the juvenile justice system and includes studying the phased closure of such facilities.
