Physical therapist assistants deliver physical therapy under a physical therapist's direction. The physical therapist examines the patient and sets the treatment plan; the assistant carries out that plan, collects data and reports back to the therapist, who stays responsible for the plan and adjusts it.

According to APTA, about 72 percent of physical therapist assistants work in hospitals or privately owned outpatient practices, with others in home health, schools and skilled nursing or long-term care. They treat people of all ages, from newborns to the end of life.

Entry is through an associate degree from a CAPTE-accredited program, usually two years or five semesters, with about 75 percent classroom and lab study and 25 percent clinical education, including an average of 16 weeks of full-time clinical experience. CAPTE accredits more than 390 assistant programs. Graduates then pass a national examination to obtain the license or certification that most states require.

After licensure, assistants can deepen their skills through APTA's voluntary PTA Advanced Proficiency Pathways in areas such as acute care, geriatrics, neurology, orthopedics, pediatrics and wound management. The program is not required to work in any area.

A general description of the profession. It does not say what you may do under your license; for that, see the scope statuses below and your state board.

How it is regulated

The national layer. States add their own requirements, and the state board has the final word.

State license

A license from a state board is what authorizes practice. Each state sets its own requirements, and a national exam, where there is one, is a step toward the license rather than a substitute for it. There is no national license.

Licensure

State-regulated in most states. The PTA scope is defined by what the supervising physical therapist may delegate, which makes the state's supervision rule as important as the license itself.

PT Compact

Operational

Operational and issuing privileges. The most mature compact in these professions, covering physical therapists and physical therapist assistants.
