Any town, on its own initiative or upon a request by the Secretary of the State, and with the approval of the legislative body of the town or, in the case of a town in which the legislative body is a town meeting, the board of selectmen, may require a spare voting tabulator or ballot box to be provided inside any polling place or in a room adjacent to the polling place, for the educational use of students from kindergarten to grade twelve, inclusive. Upon such approval, the registrars shall establish procedures for the use of the tabulator or ballot box, including but not limited to: (1) Location and preparation of the tabulator or ballot box, (2) duties of tabulator or ballot box tenders, and (3) canvassing the returns. Any such tabulator shall be in addition to the demonstrator or spare voting tabulator required by § 9-260. Ballots completed by students under this section shall be unofficial, and polling place officials shall not be required to handle or count such ballots. Each student who will be using such tabulator or ballot box inside a polling place or a room adjacent to the polling place shall be accompanied by an adult. The supervisor of such students for the purposes of this section shall submit the names of all adults who will be working with such students to the registrars at least forty-eight hours before the election.
