Ohio Rev. Code § 3313.13
Except as otherwise provided in this section, no prosecuting attorney, city director of law, or other official acting in a similar capacity shall be a member of a board of education.
An assistant prosecuting attorney may serve as a member of a board of education of a school district in any county other than the county in which the assistant prosecuting attorney is employed if the board of education's school district is not contiguous to the county in which the assistant prosecuting attorney is employed.
A city director of law who was appointed to that position under a city charter, village solicitor, or other chief legal officer of a municipal corporation may serve as a member of a board of education for which the chief legal officer is not the legal adviser and attorney under section 3313.35 of the Revised Code. A city director of law who was appointed to that position under a city charter may serve as a member of a board of education for which the city director of law is the legal adviser and attorney under section 3313.35 of the Revised Code, but only if the board uses no legal services of the office of the city law director or if the legal services of that office that it does use are performed under contract by persons not employed by that office. An employee of an appointed or elected city director of law may serve as a member of a board of education for which the city director of law is not the legal adviser and attorney under section 3313.35 of the Revised Code.
