Section 16B of Chapter 71 of the General Laws, as appearing in the 2008 Official Edition, is hereby amended by striking the first sentence of the first paragraph and replacing it with the following sentences:--

Notwithstanding any general or special law to the contrary, the regional district school committee, by a two-thirds vote of all its members, shall annually determine the amounts necessary to be raised, after deducting the amount of aid such district is to receive pursuant to section sixteen D, to maintain and operate the district school or schools during the next fiscal year, and amounts required for payment of debt and interest incurred by the district which will be due in the said year, and shall apportion the amount so determined among the several municipalities by finding an amount per pupil by dividing the amount by the number of children who attended a school in the district in that fiscal year, and assigning each municipality a contribution equal to the amount per pupil multiplied by the number of children from that municipality attending a school in the district in fiscal year.
