Ohio Rev. Code § 3311.10
If an exempted village school district fails to contain within its territorial boundaries territory lying within the corporate limits of a village having a population, according to the latest federal census of two thousand or more, such exempted village school district shall become a local school district, subject to the supervision of the educational service center governing board for the school year commencing the first day of July following the publication by the secretary of state of such census, and thereafter. This section does not apply to any exempted village school district organized as such exempted village school district prior to June 1, 1943.
The board of education of an exempted village school district that contains within its boundaries all or part of two or more municipal corporations, the aggregate population of which totals five thousand or more as determined by the preceding federal census, may, by a majority vote of the full membership of the board, propose that such district become a city school district. The proposal shall be filed with the state board of education. The state board of education shall either approve or disapprove the proposal and shall notify, in writing, the board of education of the district of its decision within ninety days of the day on which the proposal was received.
A school district created by the state board of education under section 3311.37 of the Revised Code which includes any combination of two or more exempted village or local school districts may be designated as a city school district by the state board of education, provided the aggregate population of the newly created district totals five thousand or more as determined by the last federal or special census and provided there is contained within its boundaries all or part of a municipal corporation.
When a governing board of an educational service center is dissolved pursuant to section 3311.37 of the Revised Code the employees shall be assured the opportunity of continued employment in the newly created school district in similar positions at no reduction in salary until the expiration of the existing contracts. Nonteaching school employees of city school districts, created pursuant to this section, shall not be employed pursuant to Chapter 124. of the Revised Code, except that sick leave shall be granted pursuant to section 124.38 of the Revised Code.
