Physical Therapist Assistant Job Description

A physical therapist assistant, or PTA, is a licensed clinician who delivers the treatment a physical therapist has planned. The PT examines the patient, makes the diagnosis, writes the plan of care and sets the goals. The PTA carries that plan out visit by visit, gathers data on how the patient responds, and works with the PT when the plan needs to change. The American Physical Therapy Association puts it in exactly those terms: PTAs "implement components of patient care, obtain data related to the treatment provided, and collaborate with the physical therapist to modify care as necessary."

A treatment session, start to finish

A visit opens with a check-in: pain level, sleep, how the home program went, whether the knee swelled after the last session. The PTA reads the plan and the previous note, then runs the session. That might be quad sets and step-ups for a post-operative ACL, gait training with a rolling walker after a hip replacement, balance work for a patient with Parkinson's disease, or neuromuscular electrical stimulation for a quadriceps that will not fire. The Bureau of Labor Statistics lists the core tasks as observing patients before, during and after therapy, helping them do specific exercises, treating with techniques such as massage and stretching, using devices such as walkers, and teaching patients and family members what to do after treatment.

The craft is in the adjustments. A good PTA adds load when a patient is ready, backs off when a pain response or a vital sign says to, and catches the change that belongs in front of the PT: new numbness, an incision that looks angry, a sudden drop in walking speed. Documentation closes the loop. Each visit gets a daily note in the clinic's EMR, whether that is WebPT, Raintree or Epic, recording the interventions, the patient's response and the units billed.

The boundaries are just as defined. Initial evaluations, re-evaluations, diagnosis, discharge decisions and changes to the plan of care belong to the PT. State practice acts draw the exact lines, including how often the PT must see the patient and which manual techniques an assistant may use, so a PTA who moves across a state line can find a slightly different scope on the other side.

Where PTAs work

BLS counted about 114,100 physical therapist assistant jobs in 2025. Offices of physical, occupational and speech therapists and audiologists employed 44 percent of them, hospitals 20 percent, home healthcare services 12 percent, skilled nursing facilities 10 percent and offices of physicians 6 percent.

Each setting runs differently. Outpatient orthopedic clinics book patients in tight blocks, with post-surgical and sports caseloads and a steady stream of notes. Hospital PTAs work the acute-care floors, getting patients up after surgery or a stroke and preparing them for discharge. Home health PTAs drive between visits and treat in living rooms, where the front steps and the bathroom are the real test. In skilled nursing facilities the work centers on transfers, walking and the daily skills a resident needs to get home or stay safe.

The physical load is part of the job. BLS notes that PTAs must often lift and move patients, which leaves them vulnerable to back injuries, so safe-handling technique and a gait belt are standard kit. Some clinics keep extended hours, and in those settings evening and weekend shifts come with the territory.

Education

The entry route is an associate degree from a PTA program accredited by the Commission on Accreditation in Physical Therapy Education (CAPTE). BLS reports that all states require physical therapist assistants to have an associate's degree from an accredited program, and that programs typically last about 2 years, with coursework in anatomy, physiology and kinesiology plus supervised clinical work.

APTA describes the split inside a program: approximately 75 percent of the PTA curriculum is classroom and lab study, and the remaining 25 percent is clinical education. CAPTE's aggregate data for 2025 puts the mean at 15.9 weeks of full-time clinical education per program. Cost depends heavily on the school. For 2025-26, CAPTE reports a mean total cost of the professional program, excluding room and board, of $13,790 at public programs for in-district students and $44,938 at private programs.

As a rough guide, expect prerequisite courses such as anatomy and physiology before the professional phase starts, and treat any observation hours a program asks for as a chance to see whether outpatient, hospital or home health work suits you.

Licensure and the NPTE

BLS notes that all states require physical therapist assistants to be licensed or certified, and that licensure typically requires graduation from an accredited program and passing a qualifying exam. That exam is the National Physical Therapy Examination for PTAs (NPTE-PTA), administered by the Federation of State Boards of Physical Therapy (FSBPT). The PTA version has 4 sections and 180 questions with 4 hours of testing time, and FSBPT gives it at Prometric testing centers on set dates four times per year, in January, April, July and October. Because the dates are fixed, a new graduate who misses one window waits for the next, so plan the application around the calendar.

Some states add an exam on the state's physical therapy law, a criminal background check and a minimum age of 18, according to BLS, and PTAs may need continuing education to keep the license. Check the state board before you apply.

Certifications and skills

BLS notes that PTAs may earn certifications in CPR or Basic Life Support. The American Heart Association's Basic Life Support (BLS) course and the American Red Cross's Basic Life Support course both cover that.

Once licensed and working, an experienced assistant can pursue APTA's PTA Advanced Proficiency Pathways, an assessment-based certificate program for APTA members in eight areas: acute care, cardiovascular and pulmonary, geriatrics, neurology, oncology, orthopedics, pediatrics and wound management. Applicants work with a supervising physical therapist and a PT clinical mentor, and the recognition is good for 10 years.

The skills that carry the job are practical: anatomy applied in real time, safe patient handling, plain-language teaching for home programs, and notes that hold up when a payer reviews them. As a rough guide, a few years in one setting is a reasonable point to start serving as a clinical instructor for students or to look at a lead PTA role.

Growth and openings

BLS projects employment of physical therapist assistants to grow 23 percent from 2025 to 2035, reaching 140,400 jobs, against 3 percent for all occupations. For assistants and aides together, BLS expects about 24,900 openings a year on average over the decade, many of them to replace workers who transfer to different occupations or retire. The agency ties demand to the health needs of an aging population and to outpatient and long-term care providers that are expected to rely on PTAs to reduce the cost of physical therapy services.

The licensed workforce

The Federation of State Boards of Physical Therapy's 2025 census counted 134,457 unique physical therapist assistants with active licenses in the United States, with data current as of Dec. 31, 2025. Florida held the largest number of PTA licenses. The census put the mean age of PTAs at 42, and 68 percent of PTAs with sex reported were female.

The education pipeline

CAPTE's 2025 fact sheet shows the number of accredited and candidate PTA programs at 380 in 2025, down from 413 in 2020. Programs reported a mean first-time licensure pass rate of 79.2 percent for 2025 and a mean ultimate pass rate of 85.0 percent, and a mean employment rate of 99.1 percent 12 months after graduation. For an applicant comparing schools, each program's own first-time pass rate is the number worth asking for.

Medicare rules that shape PTA staffing

Medicare pays differently when an assistant treats. Since Jan. 1, 2022, CMS has paid 85 percent of the otherwise applicable Physician Fee Schedule amount for physical therapy furnished in whole or in part by a PTA, and claims flag those services with the CQ modifier. Under CMS's de minimis standard, portions of a service a PTA furnishes independently of the PT that do not exceed 10 percent of the total service are not subject to the reduction. In Part B outpatient work, how a session is divided between PT and PTA therefore shows up on the claim.

Supervision rules eased. The CY 2025 Physician Fee Schedule final rule, effective Jan. 1, 2025, allowed general supervision of PTAs by physical therapists in private practice for all applicable PT services, which CMS said aligns with the general supervision policy for PTAs supervised by PTs who work for institutional providers. TRICARE followed: Humana Military announced on Sept. 18, 2025 that general supervision is acceptable for PTAs supervised by physical therapists in private practice, meaning the PT does not have to be physically present but must remain available for consultation and direction. Payer rules sit on top of state practice acts, so a clinic still has to meet its own state's supervision standard.

The next round started as a proposal. In July 2026, APTA Private Practice summarized the CY 2027 proposed rule: a 1.68 percent reduction in the conversion factor most physical therapy practices would receive, and a plan to pay for remote therapeutic monitoring only when it is furnished by clinical staff employed by the practice. CMS put the CY 2027 final rule on public display on Nov. 4, 2026, ahead of Federal Register publication on Nov. 9, so check what it finalized before planning a schedule or a staffing model around those proposals.

Dear Ms. Alvarez,

I am applying for the Physical Therapist Assistant opening at Riverbend Orthopedic & Sports Rehab. I passed the NPTE-PTA this spring, hold an active state license, and completed my final clinical rotation at an outpatient orthopedic clinic much like yours, where I treated post-operative knees and shoulders under the supervision of two physical therapists.

That rotation taught me what a PT needs from an assistant. My clinical instructor wrote the plan of care; my job was to run it well and tell her what I saw. When a patient three weeks out from a rotator cuff repair started compensating with his upper trapezius during supported elevation, I stopped the progression, documented the change and flagged it before his next visit. She adjusted the plan the same day. I would bring that same habit to Riverbend: follow the plan precisely, progress within it, and raise anything that falls outside it.

I am comfortable in a fast outpatient schedule. I wrote daily notes in WebPT during the rotation and learned to finish them between patients rather than at the end of the day. I can set up and run electrical stimulation, teach a home exercise program so a patient can repeat it back, and handle transfers safely with a gait belt for patients who arrive on crutches or a walker.

Earlier, I worked as a physical therapy aide at a community hospital while finishing my prerequisites. Cleaning tables and stocking theraband is not glamorous, but it showed me how a clinic runs when the support work is done right, and I still do it without being asked.

I would welcome the chance to meet your team and observe a morning in the clinic. Thank you for considering my application.

Sincerely, Jordan Ellis, PTA
