HB 2188 requires Tennessee's Department of Children's Services (DCS) to create a formal agreement with the Department of Disability and Aging (DDA) to improve support for children in state custody or at risk of entering custody who have intellectual or developmental disabilities (I/DD). The bill mandates DDA to evaluate children with suspected I/DD, recommend appropriate placements, oversee service quality, develop staff training, and coordinate disability-specific care. It directly affects children with I/DD in or near state custody, DCS staff, and service providers. The law also requires DCS to submit annual reports to legislative committees detailing referrals, evaluations, placements, oversight findings, and training status by January 1, 2027, and annually after.
