Which of the following roles is NOT represented on the board?

The role of a medical doctor is not typically represented on the board governing the practice of physical therapy. Most state boards for physical therapy primarily include professionals who are directly engaged in physical therapy or related fields to ensure that the regulation of the profession remains relevant and specific to the practice at hand.

Public members, physical therapist assistants, and physical therapists each bring essential perspectives and expertise relevant to the board's functioning and the regulation of physical therapy within that state. Public members provide insights from the public's viewpoint, while physical therapist assistants and licensed physical therapists contribute their professional knowledge and experience. Including a medical doctor, although their input can be valuable, falls outside the typical composition designed to focus primarily on the physical therapy profession itself. Thus, it makes sense that a medical doctor would not hold a position on the physical therapy licensing board.
