Tenn. Code Ann. § 37-1-180

If the court sets a hearing to review the status of the child under § 37-1-179, the child shall have the same rights as in the original commitment proceeding under §§ 33-3-605, 33-3-608, 33-3-610 — 33-3-616, and 33-3-620. If and only if the court finds on the basis of clear, unequivocal, and convincing evidence that the child is subject to commitment to the custody of the department under § 37-1-175, the court may order that the child remain in the temporary legal custody of the department. If the court does not so find, the department's custody terminates at the end of the hearing.
