Under what condition can the number of PTAs supervised by a PT exceed the general limit of 2?

The correct condition under which a physical therapist (PT) may supervise more than the general limit of two physical therapist assistants (PTAs) is when prior approval is granted by the Physical Therapy Board of California (PTBC). This additional supervision can be necessary in certain situations, such as when a PT is working in a specialized setting or during times of increased demand for physical therapy services. Obtaining prior approval ensures that the PTBC can evaluate the circumstances for justification of this exception, maintaining the quality of patient care and oversight.

The other options do not align with the established regulations governing PT supervision of PTAs. Simply receiving additional funding, completing extra training, or having no patients in the facility does not provide a valid regulatory basis for exceeding the supervisory limit. Supervisory ratios are designed to ensure adequate oversight, and any changes to these limits must be assessed and authorized by the official regulatory body, the PTBC.
