Physical Therapy Assistant vs Physical Therapy Aide

Share This Post

Physical Therapist Assistants and aides both work under the supervision of a physical therapist as support members. However, physical therapist assistant is a field that requires more education, and physical therapist aides are usually trained after becoming employed, do not require certification or credentialing, and can seek employment directly after graduating from high school.

Physical Therapy Assistant Vs Physical Therapy Aide: Understanding the Roles and Choosing Your Path

pivotalplaying a pivotal role in patient rehabilitation and recovery. Within this field, two often misunderstood and conflated positions are that of a Physical Therapy Assistant (PTA) and a Physical Therapy Aide. Although they share some overlapping duties and work environments, PTAs and Aides differ significantly in their responsibilities, education requirements, and scope of practice.

In this comprehensive examination, we will dissect the roles of PTAs and Aides, providing insights for aspiring professionals contemplating which path aligns with their career aspirations.

Defining the Roles

Physical Therapy Assistant (PTA)

A Physical Therapy Assistant is a licensed healthcare provider who works under a physical therapist’s (PT) direction and supervision. A PTA’s role is hands-on and directly involved with patient care. PTAs help patients perform specific exercises, administer modalities like electrical stimulation and ultrasound, and track patient progress. They are also responsible for educating patients and their families about treatment plans and how to achieve optimal outcomes.

A robust academic background is required to become a PTA. It typically includes earning an Associate’s degree from an accredited PTA program and passing the National Physical Therapy Examination (NPTE) for PTAs.

Physical Therapy Aide

On the other hand, the Physical Therapy Aide—sometimes referred to as a tech or attendant—is less clinical and more supportive. Aides are not licensed, and their tasks often revolve around keeping the therapy environment running smoothly. They are responsible for preparing treatment areas, cleaning equipment, doing laundry, escorting patients, and potentially assisting with clerical work like scheduling and reception duties. Hands-on patient care is not within an Aide’s scope of practice.

Most Aide positions require a high school diploma or equivalent, and training for the role is typically provided on the job.

Education and Certification

Education for PTAs

PTAs require formal education, which usually lasts about two years. During this period, students take courses in anatomy, physiology, biomechanics, kinesiology, neurology, and various physical therapy modalities. Clinical rotations, where students gain hands-on experience in multiple settings such as hospitals, outpatient clinics, and skilled nursing facilities, are also a key component of PTA education.


After completing their education, PTAs must pass the National Physical Therapy Exam (NPTE) to obtain a license to practice. Furthermore, depending on the state, PTAs may need to complete continuing education credits to maintain their licensure.

Education for Aides

Education for Physical Therapy Aides is typically less formal and comprehensive. As mentioned, a high school diploma or GED is often sufficient to secure a job, with on-the-job training employers provide. However, some Aides might opt for a vocational school or community college certificate to enhance their knowledge base and employability.

Scope of Practice

A PTA’s scope of practice is broad, and while they do not develop treatment plans independently, they play a direct role in delivering care based on a PT’s guidelines. Their day-to-day activities can vary widely based on the needs of the patients. Some typical responsibilities include:

  • Implementing selected components of patient/client interventions (treatment)
  • Obtaining data related to the interventions provided
  • Making modifications in selected interventions either to progress the patient/client as directed by the physical therapist or to ensure patient/client safety and comfort

Top Duties

Aides do not have a defined scope of practice since they do not perform clinical functions; rather, they assist PTs and PTAs with operational tasks. This can include:

  • Transporting patients
  • Cleaning and organizing work areas and equipment
  • Assisting patients with moving to or from a therapy area
  • Performing administrative tasks

Work Settings and Environments

PTAs and Aides can work in various settings where physical therapy services are provided, including hospitals, private practices, outpatient clinics, home health agencies, schools, sports facilities, and rehabilitation centers.

However, due to the clinical nature of their work, PTAs often require more adaptive environments depending on their specialization, such as private rooms for one-on-one therapy or open gym spaces for exercise and mobility training. Aides typically work in settings where their role is supportive, be it behind a desk or within treatment areas doing preparatory or cleaning tasks.

Career Opportunities and Advancement

For PTAs, there is potential for advancement through specialization. PTAs can pursue further education, obtaining certifications in pediatrics, geriatrics, or sports rehabilitation. They can also further their education to become a licensed Physical Therapist, although this requires a substantial commitment to complete a Doctor of Physical Therapy (DPT) program.

Aides have limited advancement opportunities due to limited licensing and a more restricted role. However, becoming an Aide can be a stepping stone for those considering a career as a PTA or PT, offering them exposure to the field and the opportunity to decide if pursuing additional education is the right path for them.

Salary and Job Outlook

The salary and job outlook for PTAs tend to be more favorable, reflecting their higher level of responsibility and the technical skills required for the role. According to the U.S. Bureau of Labor Statistics (BLS), the median annual wage for PTAs was $58,790 in May 2019. The job outlook is also promising, with employment of PTAs projected to grow 33% from 2019 to 2029, much faster than the average for all occupations.

In contrast, Physical Therapy Aides have lower earning potential. The BLS reported a median annual wage of $31,410 in May 2022. Job growth for aides is similar to the average for all occupations, with an expected increase of 19% from 2022 to 2032.

The main difference between these two positions is the level of treatment provided to patients. The PT Aide does not directly engage in patient treatment, but rather supports the physical therapist and assistant by performing clerical duties and preparing equipment, among other tasks.

Conversely, the physical therapy assistant has a more hands-on role, helping implement patient treatment plans under the supervision of a licensed physical therapist. As such, they require a higher level of education and have a higher salary than aides.


Choosing between becoming a PT Assistant or Aide depends on your career goals, desired level of patient interaction, and commitment to education. Each role offers unique challenges and rewards, with PTAs enjoying greater autonomy and involvement in patient care and Aides having a more supportive function.

If you are passionate about helping others and contributing to their healing and rehabilitation, a career as a PTA may be more fulfilling. Still, starting as an Aide can give you invaluable experience in the field and a clearer insight into whether this is the right professional path for you.
Remember, regardless of the title you pursue in physical therapy, you will be part of a dedicated team improving lives.
