Who is responsible for signing the certificate of registration for chiropractors?

The correct choice identifies the specific roles within the professional board responsible for overseeing the registration of chiropractors. In Massachusetts, the Chairman and Secretary of the Board hold designated authority to sign certificates of registration, ensuring that the process adheres to the established regulatory framework. This procedure maintains the integrity and official status of the registration process, as it signifies that all necessary requirements have been met and that the chiropractor is officially recognized to practice.

The Chairman often leads the board meetings and oversees general operations, while the Secretary manages documentation and communication. Their collaborative efforts ensure that certificates are issued in a legally compliant and systematic manner, reflecting the board's official endorsement of the chiropractor's qualifications and ability to practice.

Other roles or positions, such as the President and Vice President of the Board, while important, do not specifically bear the responsibility of signing the certificate of registration, making this choice distinct and correct in the context of the question.
