What does a physical therapist assistant do?
Physical therapist assistants help patients get moving again. Their patients include people recovering from surgery, sports injuries, strokes and car accidents, as well as older adults working to stay strong and prevent falls. PTAs work under the direction and supervision of a licensed physical therapist.
The physical therapist evaluates each patient and creates a treatment plan. The PTA then carries out much of that plan. That can include teaching exercises, stretching, balance and walking training, and using treatments like heat, cold and electrical stimulation. PTAs also help patients learn to use canes, walkers and other devices.
PTAs track each patient’s progress and report changes to the physical therapist, who can adjust the plan. Encouragement is a big part of the job, because recovery can be slow and frustrating.
Documentation matters too. PTAs write notes after each session that show what was done and how the patient responded.
PTAs need patience, a positive attitude and good body mechanics. You will help people stand, walk and move safely, sometimes when they are weak or in pain. You also need to explain exercises clearly, notice when something is not right, and adjust within the plan the physical therapist set. Many PTAs say the best part of the job is watching a patient walk out on their own after weeks of hard work.
Tools of the job include exercise equipment, resistance bands, balance tools, treatment tables, gait belts, electrical stimulation units and documentation software.

- Outpatient physical therapy clinics

Physical therapist assistant pay and job outlook
According to the U.S. Bureau of Labor Statistics, physical therapist assistants earn a median of $68,380 a year, or $32.88 an hour. Pay often varies by setting, with home health and skilled nursing jobs sometimes paying more than outpatient clinics.
The BLS counts about 114,100 PTA jobs. Employment is projected to grow 23% from 2025 to 2035, much faster than most occupations. That means about 18,500 openings each year.
Pros
- Very strong projected growth.
- Solid pay for a two-year degree.
- Active work, rather than sitting at a desk.
- You see patients make real progress over time.
Cons
- Programs are competitive and may have waitlists.
- The work is physically demanding, with lifting and guiding patients.
- You must work under a PT’s direction, so your independence is limited.
- Some settings have high caseloads and productivity targets.
Training options: an accredited degree is required
There is no apprenticeship or on-the-job route to becoming a PTA. Every state requires graduation from a CAPTE-accredited program before you can take the NPTE-PTA.
Associate degree. PTA programs are offered mainly by community and technical colleges. They usually take about two years and include classroom learning, hands-on lab practice and full-time clinical experiences in real therapy settings.
Costs vary widely, from several thousand dollars at some public community colleges to $40,000 or more at private schools.
Starting as a PT aide. Working as a PT aide is a good way to get observation hours and see if you like the field. It can strengthen your application, but it does not replace the degree.
Certification and licensing by state
Every state regulates PTAs. Most require a license, while a few use certification or registration. To qualify, you generally must:
- Graduate from a CAPTE-accredited PTA program
- Pass the NPTE-PTA from FSBPT
- Pass a state law (jurisprudence) exam, if your state requires one
Supervision rules vary by state. Some states require the PT to be on site, while others allow general supervision in certain settings. Medicare also has its own supervision rules for some settings. Continuing education and renewal schedules vary by state too.
Many states belong to the Physical Therapy Licensure Compact, which lets PTAs licensed in one member state get a privilege to work in other member states.
Specializations and where they lead
- Orthopedics and sports. Help patients recover from injuries, joint replacements and sports surgeries.
- Geriatrics. Work with older adults on strength, balance and fall prevention.
- Neurology. Help patients recovering from strokes, brain injuries and other neurological conditions.
- Pediatrics. Work with children in clinics or schools.
- Clinic leadership or physical therapist. Experienced PTAs can become clinic coordinators or go back to school for a Doctor of Physical Therapy degree. APTA also offers advanced proficiency recognition for PTAs.
How to choose a PTA school
The right program gets you through the NPTE-PTA and ready to treat patients. Ask these questions:
- Is the program accredited by CAPTE? You cannot take the NPTE-PTA without it.
- What are your NPTE-PTA pass rates and graduation rates? CAPTE requires programs to publish outcomes.
- Where do clinical experiences take place? Ask about the mix of outpatient, hospital and long-term care settings.
- What are the admission requirements? Ask about prerequisites, observation hours, GPA and waitlists.
- What is the total cost? Include books, lab fees, travel to clinical sites and exam fees.
- What is the employment rate for graduates? This is another outcome CAPTE programs report.
- Can I take classes part time or in the evening? Some programs offer hybrid or flexible schedules.
