Tenn. Code Ann. § 49-1-213

Within available resources, the department may provide technical assistance to LEAs through the implementation of a trainer of trainers model. Each LEA may identify its own technical assistance persons from general and special education to serve local schools. Technical assistance persons would serve as trainers to the district's local technical assistance persons. Local technical assistance persons may then provide hands-on consultation in the classrooms and in school in-services related to the needs of children having behavioral or emotional disorders.
