Which of the following is NOT a duty of the Tennessee Board of Cosmetology?

The choice of setting retail prices for services is correct because the Tennessee Board of Cosmetology does not have the authority to dictate or regulate the prices that cosmetology businesses charge for their services. Instead, issues related to pricing are left to individual cosmetologists and salon owners, allowing for competitiveness and market-driven decisions within the beauty industry.

The board's responsibilities instead include tasks like issuing licenses to practitioners, conducting inspections to ensure compliance with health and safety standards, and enforcing regulations that govern the practice of cosmetology. These duties are aimed at maintaining professional standards and ensuring public safety, which are critical aspects of the board's mandate.
