(a) Each local board of education shall prepare an itemized estimate of the cost of maintenance of public schools for the ensuing year and shall submit such estimate to the board of finance in each town or city having a board of finance, to the board of selectmen in each town having no board of finance or otherwise to the authority making appropriations for the school district, not later than two months preceding the annual meeting at which appropriations are to be made. The money appropriated by any municipality for the maintenance of public schools shall be expended by and in the discretion of the board of education. Except as provided in this subsection, any such board may transfer any unexpended or uncontracted-for portion of any appropriation for school purposes to any other item of such itemized estimate. Boards may, by adopting policies and procedures, authorize designated personnel to make limited transfers under emergency circumstances if the urgent need for the transfer prevents the board from meeting in a timely fashion to consider such transfer. All transfers made in such instances shall be announced at the next regularly scheduled meeting of the board. Expenditures by the board of education shall not exceed the appropriation made by the municipality, with such money as may be received from other sources for school purposes. If any occasion arises whereby additional funds are needed by such board, the chairman of such board shall notify the board of finance, board of selectmen or appropriating authority, as the case may be, and shall submit a request for additional funds in the same manner as is provided for departments, boards or agencies of the municipality and no additional funds shall be expended unless such supplemental appropriation shall be granted and no supplemental expenditures shall be made in excess of those granted through the appropriating authority. The annual report of the board of education shall, in accordance with section 10-224, include a summary showing (1) the total cost of the maintenance of schools, (2) the amount received from the state and other sources for the maintenance of schools, and (3) the net cost to the municipality of the maintenance of schools. For purposes of this subsection, “meeting” means a meeting, as defined in section 1-200.

      (b) The Commissioner of Education shall develop a financial information system to assist local and regional boards of education in providing to the State Board of Education budget and year-end expenditure data in conformance with the provisions of section 10-227. The financial information system shall be consistent with regulations concerning guidelines for municipal financial reports adopted by the Secretary of the Office of Policy and Management pursuant to the provisions of section 7-394a.
