What are the qualifications required to become a Worshipful Master?

Under the United Grand Lodge of England Book of Constitutions, a candidate nominated to serve as the Master of a Lodge must first have served the office of Warden in a regular Lodge. Beyond this constitutional requirement, traditional practice requires that he be presented as a brother of good morals, great skill, true and trusty, possessing the requisite care and capacity to govern 1.

Before he can be installed, the Master-elect must formally signify his assent to a summary of ancient charges and regulations 1. The ancient charges require him to be a good man and true, strictly obey the moral law, live creditably and act honourably, guard against intemperance, remain courteous and faithful to his lodge, and discountenance all impostors and dissenters from the original plan of Masonry 1. The regulations further bind him to permit no innovations in the body of Masonry, pay homage to the Grand Master and Grand Lodge, attend its communications, and maintain good order and regularity within his lodge 1.

General prerequisites discussed in an article on the Grand Lodge of India website similarly highlight that a member must be willing to obey, hold office when called upon, carry out orders, and obey the summons of the Worshipful Master.
