Final answer:
a. Direct supervision. The level of supervision for a PT to PTA student can range from direct supervision to independent practice.
Step-by-step explanation:
The level of supervision for a PT to PTA student can vary based on the tasks and skills being performed. In general, a PT to PTA student will start with direct supervision, where a licensed physical therapist closely observes and guides the student. As the student gains experience and proficiency, they may progress to minimal supervision, where the PT provides oversight but allows the student to work independently with periodic check-ins. Further progression can lead to moderate supervision, where the PT closely monitors and assists the student but gives them more autonomy in patient care. Finally, as the student meets competency requirements, they can reach the level of independent practice.
