True or False: Each school must display a sign stating "All services in this school are performed by students only."

The statement is true because Tennessee's cosmetology laws mandate that any cosmetology school must clearly inform the public that all services provided are performed exclusively by students. This requirement serves to ensure transparency and to manage the expectations of clients who are receiving services at the school. Displaying a sign that states "All services in this school are performed by students only" helps to clarify that the individuals providing these services are in training and may not yet be licensed professionals. This is an important aspect of consumer protection within the beauty industry, as it allows clients to make informed decisions regarding the services they receive in an educational environment.

This requirement emphasizes the role of schools in training future professionals while ensuring the public is aware of the nature of the services offered. By clearly communicating that students are performing the services, schools uphold standards of accountability and integrity within the industry.
