SB 939 requires Tennessee's TACIR (Tennessee Advisory Commission on Intergovernmental Relations) to study the economic impact of cosmetology and barbering professions in the state, including revenue generated and jobs created. The study must use TACIR's existing resources and may request input from the Department of Commerce and Insurance. Upon completion, TACIR must report findings and recommendations - including any proposed legislation - to the chairs of the Senate Commerce and Labor Committee and the relevant House committee, plus provide a copy to the legislative librarian. This bill does not create new laws but mandates a factual study to inform future policy decisions affecting these professions.
