What requirement must all Commissioners fulfill?

All Commissioners must be licensed auctioneers because this requirement ensures that they have a thorough understanding of the auction process, laws, and regulations governing the profession. A licensed auctioneer possesses the necessary knowledge and skills that are critical for overseeing and regulating the actions of other auctioneers. This qualification helps maintain high standards within the auction industry and provides assurance that the interests of both auctioneers and the public are protected.

The other choices do not align with the requirements for being a Commissioner, as being estate agents, board members, or financial advisors does not specifically involve the expertise or legal knowledge necessary for regulating auctioneers effectively. Only those who are licensed auctioneers possess the specialized training and experience relevant to the duties of a Commissioner in the auctioning field.
