New Jersey Statutes Title 18A. Education 18A § 7F-32

a. When State aid is calculated for any year and a part of any district becomes a new school district or a part of another school district, or comes partly under the authority of a regional board of education, the commissioner shall adjust the State aid calculations among the districts affected, or between the district and the regional board, as the case may be, on an equitable basis in accordance with the intent of this act.

Whenever an all-purpose regional school district is approved by the voters during any calendar year, the regional district shall become effective on the succeeding July 1 for the purpose of calculating State aid, and the commissioner shall request supplemental appropriations for such additional State aid as may be required. After a regional school district becomes entitled to State aid, it shall continue to be entitled to aid as calculated for a regional district notwithstanding the subsequent consolidation of the constituent municipalities of the regional school district.

b. For a period of five years following regionalization, each regional school district formed after the effective date of P.L.2007, c. 260 (C.18A:7F-43 et al.) shall be eligible to receive supplemental State aid equal to the difference between the regional district's equalization aid calculated pursuant to section 11 of P.L.2007, c. 260 (C.18A:7F-53) for the budget year and the sum of equalization aid received by each constituent district of that regional school district in the year prior to regionalization, multiplied by the transition weight. For the purpose of this section, the transition weight shall equal 1.0 for the first year following regionalization, .80 for the second year following regionalization, .60 for the third year following regionalization, .40 for the fourth year following regionalization, and .20 for the fifth year following regionalization.
