(a) For the fiscal year ending June 30, 1990, and for each fiscal year thereafter, each town shall be paid a grant equal to the amount the town is entitled to receive under the provisions of § 10-262h. Such grant shall be calculated using the data of record as of the December first prior to the fiscal year such grant is to be paid, adjusted for the difference between the final entitlement for the prior fiscal year and the preliminary entitlement for such fiscal year as calculated using the data of record as of the December first prior to the fiscal year when such grant was paid.

(b) The amount due each town pursuant to the provisions of subsection (a) of this section shall be paid by the Comptroller, upon certification of the Commissioner of Education, to the treasurer of each town entitled to such aid in installments during the fiscal year as follows: Twenty-five per cent of the grant in October, twenty-five per cent of the grant in January and the balance of the grant in April. The balance of the grant due towns under the provisions of this subsection shall be paid in March rather than April to any town which has not adopted the uniform fiscal year and which would not otherwise receive such final payment within the fiscal year of such town.

(c) All aid distributed to a town pursuant to the provisions of this section and § 10-262u shall be expended for educational purposes only and shall be expended upon the authorization of the local or regional board of education and in accordance with the provisions of § 10-262u. For the fiscal year ending June 30, 1999, and each fiscal year thereafter, if a town receives an increase in funds pursuant to this section over the amount it received for the prior fiscal year, such increase shall not be used to supplant local funding for educational purposes. The budgeted appropriation for education in any town receiving an increase in funds pursuant to this section shall be not less than the amount appropriated for education for the prior year plus such increase in funds.

(d) For any fiscal year, (1) if the amount of the equalization aid grant a town is entitled to pursuant to § 10-262h is greater than such town’s equalization aid grant amount for the prior fiscal year, the difference between the amount of such town’s equalization aid grant for the fiscal year, and such town’s equalization aid grant amount for the prior fiscal year shall be the aid increase for such town for the fiscal year, and (2) if the amount of the equalization aid grant a town is entitled to pursuant to § 10-262h is less than such town’s equalization aid grant amount for the prior fiscal year, the difference between such town’s equalization aid grant amount for the prior fiscal year and the amount of such town’s equalization aid grant for the fiscal year shall be the aid reduction for such town for the fiscal year.

(e) Upon a determination by the State Board of Education that a town or kindergarten to grade twelve, inclusive, regional school district failed in any fiscal year to meet the requirements pursuant to subsection (c) or (d) of this section or § 10-262j, the town or kindergarten to grade twelve, inclusive, regional school district shall forfeit an amount equal to two times the amount of the shortfall. The amount so forfeited shall be withheld by the Department of Education from the grant payable to the town in the second fiscal year immediately following such failure by deducting such amount from the town’s equalization aid grant payment pursuant to this section, except that in the case of a kindergarten to grade twelve, inclusive, regional school district, the amount so forfeited shall be withheld by the Department of Education from the grants payable pursuant to this section to the towns which are members of such regional school district. The amounts deducted from such grants to each member town shall be proportional to the number of resident students in each member town. Notwithstanding the provisions of this subsection, the State Board of Education may waive such forfeiture upon agreement with the town or kindergarten to grade twelve, inclusive, regional school district that the town or kindergarten to grade twelve, inclusive, regional school district shall increase its budgeted appropriation for education during the fiscal year in which the forfeiture would occur by an amount not less than the amount of said forfeiture or for other good cause shown. Any additional funds budgeted pursuant to such an agreement shall not be included in a district’s budgeted appropriation for education for the purpose of establishing any future minimum budget requirement.
