Which bureau is associated with professional and occupational affairs in the state?

The Bureau of Professional and Occupational Affairs is specifically tasked with overseeing the licensing and regulation of various professional and occupational boards within the state. This bureau plays a crucial role in ensuring that practitioners meet the necessary qualifications and standards required to provide safe and competent services in their respective fields, including nail technology. The bureau also develops policies related to the practices and conduct of licensed professionals, ensuring compliance with state laws and regulations.

The other options, while they may deal with aspects of vocational training or citizen services, do not focus primarily on the professional and occupational licensing and regulatory responsibilities that the Bureau of Professional and Occupational Affairs oversees. This distinction makes it clear why this bureau is the correct choice in relation to the question about overseeing professional and occupational affairs.
