Any person who desires a formal hearing before the board must request the same in writing. Each formal hearing must have a stenographic record, defined in section 119.09 of the Revised Code, taken of the proceedings. Unless a person specifically requests a formal hearing before the board pursuant to a disciplinary notice sent by the board in accordance with section 119.07 of the Revised Code, all other meetings of persons with a board member or a member of the board staff shall be of an informal nature with no stenographic record taken.
