Ohio Rev. Code § 4753.072
The state speech and hearing professionals board shall establish by rule pursuant to Chapter 119. of the Revised Code the qualifications for persons seeking licensure as a speech-language pathology aide or an audiology aide. The qualifications shall be less than the standards for licensure as a speech-language pathologist or audiologist. An aide shall not act independently and shall work under the direction and supervision of a speech-language pathologist or audiologist licensed by the board. An aide shall not dispense hearing aids. An applicant shall not begin employment until the license has been approved.
The board shall issue a license for a speech-language pathology aide or an audiology aide in accordance with Chapter 4796. of the Revised Code to an applicant who holds a license in another state or has satisfactory work experience, a government certification, or a private certification as described in that chapter as a speech-language pathology aide or an audiology aide in a state that does not issue those licenses.
