All states require physical therapists to be licensed, which includes passing the National Physical Therapy Examination administered by the Federation of State Boards of Physical Therapy. Other requirements vary by state. For example, some states also require a law exam and a criminal background check. Continuing education is typically required for physical therapists to keep their license. Check with your state board for specific licensing requirements.
After gaining work experience, some physical therapists choose to become a board-certified specialist. The American Board of Physical Therapy Specialties offers certification in clinical specialty areas of physical therapy, such as orthopedics, sports, and geriatrics. Board specialist certification requires passing an exam and completing clinical work in the specialty area.
