What type of degree is required for a physical therapist master or doctorate I am currently assistant and do have in another field?

To become a physical therapist, you need a Doctor of Physical Therapy (DPT) degree. A master's degree in physical therapy is no longer offered in the United States; DPT is the entry-level degree.

Your current degree in another field is irrelevant to the admission requirements *except* in that some schools may look favorably on prior experience (relevant or not). However, you will need to complete all the prerequisite coursework for a DPT program before applying, which typically includes biology, chemistry, anatomy, physiology, and other sciences. The specifics will vary by school.
