Tennessee Code Title 62. Professions, Businesses and Trades § 62-4-114

(b) Before an instructor's license expires, an instructor may notify the board of the instructor's intention to place the license on inactive status. The notice of intention shall be accompanied by the regular license fee, but the instructor shall be relieved of the obligation to attend the otherwise required board-approved training program. An instructor may stay on inactive status as long as the appropriate fees are paid on a regular basis. To change a license from inactive status to active status, the instructor shall attend a board approved instructor training program in cosmetology, manicuring, aesthetics or natural hair styling for a minimum of sixteen (16) hours.

(c) Any person who holds a valid active license as a cosmetology, manicuring, aesthetics or natural hair instructor may engage in the practice of cosmetology, manicuring, aesthetics or natural hair styling under that license; however, no instructor may render cosmetology, manicuring, aesthetics or natural hair styling services in a school, except services that are directly incidental to the instruction of students.

(d) Any person whose instructor's license expires or becomes invalid may, within sixty (60) days after the date of expiration or invalidity, obtain a cosmetologist's, manicurist's, aesthetician's or natural hair stylist's license from the board upon payment of a fee set by the board.
