The state speech and hearing professionals board shall establish a code of ethical practice for individuals licensed, certified, or registered by the board in accordance with rules adopted under Chapter 119 of the Revised Code. In establishing the codes of ethical practice, the board shall define unprofessional conduct in the rules, which shall include engaging in a dual relationship with a client or former client, committing an act of sexual abuse, misconduct, or exploitation of a client or former client, and, except as permitted by law, violating client confidentiality.

The codes of ethical practice may be based on any codes of ethical practice developed by national organizations representing the interests of those professions regulated by the board. The board may establish standards in its codes of ethical practice that are more stringent than those established by national organizations.

The board may take disciplinary action against an applicant or license holder for violating any code of ethical practice established under this section.
