School district government efficiency plans submitted by a single eligible school district. a.

As such, eligible school districts are strongly encouraged to develop a single government efficiency plan for all of the eligible school districts in their board of cooperation educational services district. However, the superintendent of each eligible school district that is not participating in a government efficiency plan with more than one signatory may submit to the director of the budget by June first, two thousand fifteen, a government efficiency plan that demonstrates three year savings and efficiencies of at least one percent per year from shared services, cooperation agreements and/or mergers or efficiencies over such eligible school district's two thousand fourteen--two thousand fifteen school year tax levy.

(ii) In the event a school district chooses to submit such a government efficiency plan, the chief financial officer of such eligible school district shall submit to the director of the budget by June first, two thousand fifteen, an analysis of the savings set forth in such plan that will be achieved if the cooperation agreements, shared services and/or mergers or efficiencies identified in such plan are fully implemented by the end of the two thousand sixteen--two thousand seventeen school year, as well as a written certification that in his or her professional opinion, full implementation of the cooperation agreements, mergers, efficiencies and/or shared services as specified in such plan will result in savings over its two thousand fourteen--two thousand fifteen school year tax levy of at least one percent in each of the two thousand sixteen--two thousand seventeen, the two thousand seventeen--two thousand eighteen and the two thousand eighteen--two thousand nineteen school years. b. The director of the budget shall review the documents referred to in paragraph a of this subdivision and shall consider past efficiencies, shared services and reforms in their approval process to determine whether the requirements of this subdivision have been met with respect to an eligible school district that has submitted a government efficiency plan and shall notify the commissioner of taxation and finance of such determination no later than July thirty-first, two thousand fifteen. * NB Effective until April 15, 2020 * § 2023-b.

Such certification shall be made in a form and manner prescribed by the state comptroller in consultation with the commissioner of taxation and finance and the commissioner. 2.
