Ohio Rev. Code § 3513.255
This section is subject to section 3513.256 of the Revised Code. The name of each candidate for election as a member of a governing board of an educational service center shall appear on the nonpartisan ballot. Each nominating petition shall be signed by fifty qualified electors who reside in one of the following, as applicable:
Each nominating petition shall be filed with the board of elections of the county in which the central administrative offices of the educational service center governing board are located not later than four p.m. of the ninetieth day before the day of the general election, provided that no such petition shall be accepted for filing if it appears to contain signatures aggregating in number more than three times the minimum number of signatures required by this section. A board of elections shall not accept for filing a nominating petition of a person if that person, for the same election, has already filed a declaration of candidacy, a declaration of intent to be a write-in candidate, or a nominating petition, or has become a candidate through party nomination at a primary election or by the filling of a vacancy under section 3513.30 or 3513.31 of the Revised Code for any other position as a member of a governing board of an educational service center or position as a member of a city, local, or exempted village board of education, or for a municipal or township office. When a petition of a candidate has been accepted for filing by a board of elections, the petition shall not be deemed invalid if, upon verification of signatures contained in the petition, the board of elections finds the number of signatures accepted exceeds three times the minimum signatures required. A board of elections may discontinue verifying petitions when the number of verified signatures equals the minimum required number of qualified signatures.
