To become a physical therapist assistant, you need an associate's degree from an accredited program, which typically takes about 2 years, and then a state licence or certification, which usually means passing a qualifying exam. Every state requires both. Physical therapist aides are different: they usually need only a high school diploma and on-the-job training.
People mix up assistants and aides all the time, and the difference changes your pay by tens of thousands of dollars. Here's what the US Bureau of Labor Statistics (BLS) said when I read its handbook on 26 October 2026.
Assistant vs aide: the difference that matters
| Physical therapist assistant | Physical therapist aide | |
|---|---|---|
| Education | Associate's degree from an accredited program | High school diploma or equivalent |
| Training | Supervised clinical work during the program | On the job, about one week to one month |
| Licence | Required or certification required in all states | Not licensed |
| Typical work | Treats patients under a physical therapist's direction | Cleans, sets up equipment, moves patients, clerical tasks |
| Median pay as of October 2026 | $68,380 a year (May 2025) | $35,240 a year (May 2025) |
That's $68,380 against $35,240 a year, and the difference comes down to the degree and the licence.
How to become a physical therapist assistant, step by step
- Finish high school with as much biology and science as you can.
- Enroll in an accredited PTA program. All states require an associate's degree from an accredited program. Programs typically last about 2 years and cover anatomy, physiology and kinesiology.
- Complete your supervised clinical work. That's where you get hands-on experience with patients.
- Pass the licensing exam. Licensure typically requires graduation plus a qualifying exam. Some states also want an exam on state physical therapy law, a criminal background check, and a minimum age of 18.
- Add CPR or basic life support. BLS says assistants may earn these certifications.
- Keep your licence current. You may need continuing education courses to maintain it.
What a physical therapist assistant does
Assistants work under the direction and supervision of physical therapists. According to BLS, you'd:
- observe patients before, during and after therapy and report to the physical therapist
- help patients do specific exercises as part of the plan of care
- treat patients with techniques such as massage and stretching
- help patients use devices like walkers
- teach patients and family members what to do after treatment
If you'd rather lead treatment plans yourself, my guide on how to become a physical therapist covers the doctoral route.
Where assistants work and earn
BLS counted about 114,100 physical therapist assistant jobs in 2025. Here's where they work:
| Employer of PT assistants (US, 2025) | Share of jobs (%) |
|---|---|
| Offices of physical, occupational and speech therapists, and audiologists | 44 |
| Hospitals; state, local, and private | 20 |
| Home healthcare services | 12 |
Home healthcare is worth noticing. It means some assistants work in patients' homes rather than a clinic, which suits people who like variety and driving between visits. For aides, the government pays the highest median, $48,360 a year, while therapy offices, which employ 65% of aides, pay a median of $34,100, as of October 2026.
Here's how aide pay compares across employers, as of October 2026:
| Employer of PT aides (US, May 2025) | Median annual wage |
|---|---|
| Government, excluding state and local education and hospitals | $48,360 |
| Nursing care facilities (skilled nursing facilities) | $43,410 |
| Hospitals; state, local, and private | $38,450 |
| Offices of physicians | $35,320 |
| Offices of physical, occupational and speech therapists, and audiologists | $34,100 |
So if you start as an aide while you save for a PTA program, a government or skilled nursing job pays noticeably more than a private therapy office.
A fast-growing field
This is the headline figure. BLS projects employment of physical therapist assistants and aides to grow 17% from 2025 to 2035, much faster than average, with about 24,900 openings a year. That's rare growth for a job you can reach with an associate's degree.

Skills you'll need
BLS lists the qualities that matter most for assistants and aides:
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
- Compassion: you work with people who are in pain, so you'll need empathy and to enjoy helping people
- Detail orientation: you keep accurate records and follow written and verbal instructions carefully
- Dexterity: assistants use their hands for manual therapy and therapeutic exercises
- Interpersonal skills: you spend much of the day talking with patients, families and the physical therapist
Add physical stamina to that list. BLS says assistants and aides are frequently on their feet setting up equipment and helping patients. If you've ever helped a relative through recovery after an injury and found it rewarding, that's a good sign this work will suit you.
My verdict
If you want hands-on healthcare work without a 4-year degree, becoming a physical therapist assistant is one of the strongest options there is: a 2-year program, a licence, strong growth and solid pay. Don't confuse it with an aide job. An aide role can be a useful taster, but the degree and licence are what lead to the assistant salary.
