A speech-language pathology assistant must be supervised by a speech-language pathologist, or a speech-language pathologist with a limited license, who has at least two years of experience. Any time licensed as a provisional speech-language pathologist counts toward the two-year experience requirement. The supervising speech-language pathologist:
(1) Is responsible for the extent, kind, and quality of service provided by the assistant, consistent with the board's designated standards and requirements;
(2) Shall ensure that persons receiving services from an assistant receive prior written notification that services are to be provided, in whole or in part, by a speech-language pathology assistant;
(3) May not supervise more than three speech-language pathology assistants at one time.
A speech-language pathology assistant may have more than one supervisor.
