Becoming a physical therapist assistant (PTA) requires an associate degree from an accredited program, followed by passing a national licensing exam. The entire process takes about two years of full-time study, making it one of the faster paths into a healthcare career with strong earning potential: the median annual wage for PTAs was $65,510 in 2024, and employment is projected to grow 22% over the next decade.
Complete an Accredited Associate Degree Program
The foundation of a PTA career is an associate degree from a program accredited by the Commission on Accreditation in Physical Therapy Education (CAPTE). This accreditation matters because graduating from a non-accredited program will make you ineligible for licensure in every state. Most programs take about two years to complete and combine classroom coursework with hands-on clinical training.
There are no universal admission requirements across PTA programs, but most expect a competitive GPA, volunteer hours in a physical therapy clinic, and a letter of reference from a licensed physical therapist. Some programs require prerequisite courses in anatomy, biology, or math before you can apply, while others build those into the curriculum. Competition for seats can be stiff, so checking each program’s specific prerequisites early gives you time to strengthen your application.
Coursework covers anatomy, kinesiology, therapeutic exercise, and patient care techniques. You’ll also study medical terminology, physiology, and the basics of common conditions that physical therapy treats, from post-surgical recovery to chronic pain management.
Clinical Training Requirements
Before graduating, PTA students must complete a minimum of 520 hours of supervised clinical experience. These rotations place you in real treatment settings where you work with patients across different age groups and conditions. Programs are designed to expose you to the range of environments where physical therapy is commonly practiced: outpatient clinics, hospitals, rehabilitation centers, skilled nursing facilities, and home health settings.
Clinical hours are where classroom knowledge becomes practical skill. You’ll practice hands-on techniques like therapeutic exercises, manual therapy, gait training, and the use of modalities such as ultrasound or electrical stimulation, all under the supervision of a licensed physical therapist. This is also where many students discover which patient populations or clinical settings they want to pursue after graduation.
Pass the National Licensing Exam
After earning your degree, the next step is passing the National Physical Therapy Examination for PTAs (NPTE-PTA), administered by the Federation of State Boards of Physical Therapy. The exam consists of 180 questions and is scored on a scaled system. You need a minimum score of 600 to pass.
The exam tests your clinical decision-making, your understanding of treatment interventions, and your knowledge of when to refer back to the supervising physical therapist. Accredited programs are held to a standard where at least 85% of graduates pass the exam within two attempts, so a quality program will prepare you well. That said, many graduates invest in additional study guides or review courses to feel confident on test day.
Get Your State License
Passing the NPTE-PTA is necessary but not always sufficient. Each state has its own licensing process, and requirements vary. Some states license PTAs while others use a certification model. Beyond the national exam, your state may require a jurisprudence exam covering local practice laws, a background check, or additional paperwork.
If you plan to work in more than one state, you’ll need to research each state’s specific requirements separately. The Federation of State Boards of Physical Therapy maintains resources to help you identify what your target state requires.
What PTAs Do (and Don’t Do)
PTAs provide direct patient care, but always under the direction and supervision of a licensed physical therapist. In practice, this means a PT evaluates the patient, develops a treatment plan, and then the PTA carries out much of the hands-on treatment: guiding patients through exercises, helping with mobility training, applying therapeutic techniques, and documenting progress.
What PTAs cannot do is evaluate patients, establish a diagnosis, or create or significantly modify the plan of care. Those responsibilities belong to the PT. The supervising PT must be available in person or by phone at all times while a PTA is treating a shared patient, and the two must regularly collaborate and document their communication about each patient’s plan. PTAs also cannot practice through direct access, meaning they can’t treat a patient without a physician referral the way a PT can in many states.
This collaborative model means your daily work feels hands-on and patient-facing. Many PTAs spend the majority of their day working directly with people rather than doing administrative tasks.
Keeping Your License Current
Once licensed, you’ll need to complete continuing education to renew your license, typically every two years. The number of required hours varies widely by state. Some states require as few as 10 continuing education units per renewal cycle (Alabama, Arizona, Arkansas), while others require 30 or more (California, Georgia, New York, Pennsylvania, Virginia). Maine currently requires none. Check your state board’s specific requirements, as these numbers can change.
Continuing education options include workshops, online courses, conferences, and specialty certifications. Many PTAs use these requirements as an opportunity to develop expertise in areas like orthopedics, geriatrics, or pediatrics.
Career Growth and Transitioning to PT
The job market for PTAs is strong. The Bureau of Labor Statistics projects 22% employment growth for PTAs from 2024 to 2034, significantly faster than average for all occupations. An aging population and growing emphasis on rehabilitation over surgery are driving demand.
Some PTAs eventually consider transitioning to become a full physical therapist. This is possible but not simple. The APTA is clear that the PTA role is not designed as a stepping stone to becoming a PT. The two curricula differ substantially, and university policies generally prevent graduate programs like the Doctor of Physical Therapy (DPT) from accepting undergraduate-level credits toward the degree.
If you want to make the transition, you’ll likely need to complete a bachelor’s degree first, then apply to a DPT program. Some of your PTA coursework may fulfill prerequisites, provided the credits aren’t more than seven to ten years old. You may also need additional courses in advanced biology, chemistry, physics, and math. Only three bridge programs currently exist that formally incorporate PTA experience into the DPT curriculum, so most PTAs pursuing this path go through a traditional DPT application process. A growing number of colleges are developing articulation agreements that help PTAs earn a bachelor’s degree in a health-related field, which can serve as preparation for a DPT application or as a standalone credential for roles in management or education.
