Tenn. Code § 63-1-122
For purposes of any action before any board, committee, council, or other agency created pursuant to this title or title 68, in which the standard of care is at issue, members of such a board, committee, council, or agency are entitled to rely upon their own expertise in making determinations concerning the standard of care and are not subject to voir dire concerning such expertise. The standard of care for such actions is a statewide standard of minimal competency and practice; provided, however, that to sustain actions based upon a violation of this standard of care, the board, committee, council, or other agency must, absent admissions or other testimony to the effect that the standard of care was violated, articulate the standard of care in its deliberations. The provisions of title 29, chapter 26, and specifically § 29-26-115(a), concerning the locality rule, do not apply to actions taken pursuant to this title or title 68.
