Medfield's executive branch of government consists of a three-member Board of Selectmen, its chief executive officers, who are elected to three-year terms. The Board of Selectmen is empowered to administer and implement decisions of Town Meeting and to establish policy and guidelines for the coordination of local government operations. The Selectmen are assisted in their duties by an appointed full-time administrator and full-time assistant administrator.
Under Medfield's Town Charter, the Selectmen also serve as Commissioners of the Police Department and as the Town Licensing Authority. The Selectmen appoint certain town officials and fill vacancies that occur in other elective positions. They establish operating and capital budgets in cooperation with all department heads under their jurisdiction.
The Board calls elections, draws up the Town Meeting Warrant and publishes Medfield's Annual Report of the Town Offices. Information is found in the Annual Report on all departments, financial matters, vital statistics, and elections. Copies may be found in the Public Library, Town House, and at the Annual Town Meeting.
The Selectmen must exercise leadership, anticipate and forestall problems, participate in long-range planning, relay accurate information by maintaining close touch with the media regarding both routine and significant events, make representative appointments and know their legal limitations and applicable laws.
