General Assembly, Directed Studies - As enacted, requires TACIR to study the availability of housing and other treatment facilities for juvenile offenders who have been adjudicated delinquent and committed to the department of children's services, and the availability of local juvenile detention centers and other facilities for the housing and treatment of juvenile offenders who have been detained by the juvenile court prior to an adjudicatory hearing; requires TACIR to report its findings and recommendations. - Amends TCA Title 37; Title 39 and Title 40.

SB 239 requires Tennessee's TACIR (Tennessee Advisory Commission on Intergovernmental Relations) to study the availability of facilities for two groups of juvenile offenders: those detained before court hearings and those committed to the Department of Children's Services after being found guilty. The study will assess current facility capacity and identify potential needs for additional housing or treatment options in both scenarios. TACIR must complete this study using existing resources and submit findings and recommendations to the General Assembly by January 1, 2026. This bill directly affects juvenile justice systems and facilities across Tennessee, though it does not create new facilities or change existing laws.
