The widest permissible scope of practice for an esthetician's massage services is determined by _________.

• A. the state
• B. the federal guidelines
• C. the salon owner
• D. the county health department

Answer: (A)

Scope of practice is defined by the state licensing framework. State boards establish the legal boundaries for what an esthetician can perform, including massage services, through statutes and rules that specify allowable techniques, labeling, and supervision, and these can vary from one state to another. That makes the state the broadest authority setting what is legally permissible. Federal guidelines provide general expectations but do not grant or limit individual services across all jurisdictions. A salon owner can implement policies within those legal limits, but cannot expand the scope beyond what the state permits. The county health department handles sanitation and safety requirements, not the overall scope of permissible practice.
