Ohio Rev. Code § 3313.23
If a treasurer of a board of education is absent from any meeting of the board the members present shall choose one of their number to serve in the treasurer's place pro tempore.
If a board of education determines the treasurer is incapacitated in such a manner that the treasurer is unable to perform the duties of the office of treasurer, the board may, by a majority vote of the members of the board, appoint a person to serve in the treasurer's place pro tempore. Each board of education shall adopt a written policy establishing standards for determining whether the treasurer is incapacitated, and shall provide that during any period in which the treasurer is incapacitated, the treasurer may be placed on sick leave or on leave of absence and may be returned to active duty status from sick leave or leave of absence. The treasurer may request a hearing before the board on any action taken under this section and shall have the same rights in any such hearing as are afforded to a teacher in a board hearing under section 3319.16 of the Revised Code. The treasurer pro tempore shall perform all of the duties and functions of the treasurer, and shall serve until the treasurer's incapacity is removed as determined by a majority vote of the members of the board or until the expiration of the treasurer's contract or term of office, whichever is sooner. The treasurer pro tempore may be removed at any time for cause by a two-thirds vote of the members of the board. The board shall fix the compensation of the treasurer pro tempore in accordance with section 3313.24 of the Revised Code, and, except as otherwise provided in section 3.061 of the Revised Code, shall require the treasurer pro tempore to execute a bond immediately after appointment in accordance with section 3313.25 of the Revised Code. If a treasurer is a member of the board, the treasurer shall not vote on any matter related to the treasurer's own incapacitation.
