Occupational Therapist Assistant Job Description

Occupational therapy splits the clinical work in two. The occupational therapist evaluates the patient, decides which functions to restore, and writes the plan of care. The occupational therapist assistant carries out much of that plan, visit after visit, and tells the therapist when it stops fitting the person in front of them. BLS describes the assistant's core tasks plainly: guiding clients in therapeutic activities, teaching new ways to accomplish everyday tasks, instructing clients in the use of special equipment, and recording progress for the therapist.

Setting shapes the day. BLS reports that 39 percent of occupational therapy assistant jobs in 2025 were in offices of physical, occupational and speech therapists and audiologists, 19 percent in skilled nursing facilities, 17 percent in hospitals, and 7 percent each in educational services and home health care.

In a skilled nursing facility, the caseload can include older adults coming off a hip fracture, a stroke or a long hospital stay, and the goals are concrete: toileting without help, dressing without a fall, getting a walker through a narrow bathroom door. In an outpatient orthopedic or hand clinic, an assistant may spend a morning on grip and pinch strengthening, edema control and fine motor work after a tendon repair. In a school, the session moves into the classroom, where a COTA might run a handwriting group, set up a sensory break before a math lesson, or practice buttons and zippers with a kindergartner. Home health strips the clinic away: the treatment happens in the patient's own kitchen and bathroom, where a tub transfer or a cluttered hallway is the real test.

Paperwork is part of the clinical job, not a side chore. Every session produces a note recording what the patient did, how much assistance they needed and how they responded, and that note supports both the therapist's reassessment and the claim. Medicare flags assistant work explicitly: services furnished in whole or in part by an OTA carry the CO modifier, which CMS says must be reported with the GO therapy modifier, and claims with modifiers not so paired are rejected as unprocessable. An assistant who knows which minutes trigger the flag saves the billing office a lot of rework.

What the assistant does not do matters as much. Evaluation, goal setting and discharge decisions belong to the occupational therapist, and the level of supervision an assistant needs is set by each state's practice act and by the payer, so the arrangement in one state's nursing homes can look quite different from a school district across the border.

The best part of the job is how visible the result is. When a patient who needed two staff members to sit up in bed walks into the therapy gym and pulls on a sweater alone, the assistant who ran those sessions knows exactly what the work produced, and so does the family watching from the doorway.

Education

• As a rough guide, the standard route is an associate's degree from an occupational therapy assistant program accredited by the Accreditation Council for Occupational Therapy Education (ACOTE). BLS notes that some bachelor's degree programs are also available, and the 2023 ACOTE Standards set requirements for both OTA baccalaureate- and associate-degree-level programs.
• BLS says associate's programs generally require 2 years of full-time study, with coursework in subjects such as anatomy, psychology and kinesiology.
• Clinical training is built into the degree. BLS says assistants must complete several months of fieldwork to gain hands-on experience, so students graduate having treated real patients under supervision in more than one kind of setting.

Certification and licensure

• Certified Occupational Therapy Assistant (COTA), awarded by the National Board for Certification in Occupational Therapy (NBCOT). To sit for the exam, a candidate must graduate from an ACOTE-accredited occupational therapy assistant program. BLS notes that assistants must pass the exam to use the COTA title and need continuing education to maintain the certification.
• State license from the state's occupational therapy licensing board. BLS says assistants usually need a state-issued license, which requires an accredited program, fieldwork and a passing exam score, and some states add requirements such as a background check.
• CPR and Basic Life Support, which BLS says assistants may need; the American Heart Association's BLS Provider course is one route to the card.
• Optional specialty credentials. BLS notes that other certifications can show particular knowledge in an area of practice, such as low vision.

Skills that carry a new graduate

• Activity analysis: breaking a task like putting on socks into steps, then grading each step up or down as the patient improves.
• Safe patient handling: gait belts, stand-pivot and sliding-board transfers, and mechanical lifts used without straining your own back.
• Documentation discipline: timely, specific notes that show skilled intervention rather than a repeated list of exercises.
• Hands-on basics such as goniometry, grip and pinch dynamometry, and simple splint or orthosis fabrication for clinics that ask for it.

Experience

• As a rough guide, the COTA is an entry-level credential, so new graduates can start applying once they pass the exam and hold a license.
• As a rough guide, a year or two in a facility, with a therapist down the hall, gives an assistant practice in clinical judgment before moving into home health, where visits happen without a therapist in the building.

Traits that hold up on the floor BLS lists adaptability, compassion, attention to detail, interpersonal skills, physical stamina and physical strength. In practice that means patience with slow, uneven progress, the creativity to turn a stalled goal into a different activity, and the precision to follow the therapist's written plan exactly while still reading how the patient looks today.

BLS projects employment of occupational therapy assistants to rise from 52,200 jobs in 2025 to 63,400 in 2035, a 21 percent increase. For the broader assistants-and-aides group, BLS calls its 20 percent projection much faster than the average for all occupations and expects about 8,600 openings a year on average across both jobs, many of them to replace workers who move to other occupations or leave the labor force.

The demand case BLS makes is demographic. Older adults are more prone than young people to conditions such as arthritis and strokes that affect the ability to do everyday activities, and assistants will be needed to help occupational therapists care for them. BLS adds an economic argument: healthcare providers, especially those specializing in long-term care, will continue to employ occupational therapy assistants to reduce the cost of occupational therapy services.

Medicare complicates that cost logic on outpatient claims. Under section 53107 of the Bipartisan Budget Act of 2018, Medicare pays 85 percent of the otherwise applicable fee schedule amount for occupational and physical therapy furnished in whole or in part by assistants, effective January 1, 2022, and CMS's therapy services page, updated for CY 2026, still describes that rate. In Part B outpatient practice, then, how much of a visit the assistant delivers changes what the claim pays.

Other CY 2026 rules touch the work directly. CMS set the CY 2026 KX modifier threshold for occupational therapy services at $2,480. The CY 2026 Physician Fee Schedule final rule also designated three new remote therapeutic monitoring codes (98979, 98984 and 98985) as sometimes therapy, and section 6209 of the Consolidated Appropriations Act, 2026 extended the ability of PTs, OTs and SLPs to furnish telehealth services through December 31, 2027. Whether an assistant can deliver a given remote service under a supervising therapist depends on state law and the payer, so check both before assuming it is billable.

Setting moves pay. In May 2025, BLS reported median wages for occupational therapy assistants of $77,310 in home health care services, $76,780 in skilled nursing facilities, $70,740 in offices of physical, occupational and speech therapists and audiologists, $67,020 in hospitals, and $60,920 in educational services. School roles follow the district's academic calendar, and home health adds driving time between visits to the workday.

Advancement runs along two tracks. Within the assistant role, people build depth in a population, such as pediatrics, hand and upper-extremity rehab, low vision or dementia care, take on fieldwork students as clinical instructors, or move into rehab coordination and scheduling in a skilled nursing building. The other track is more school: BLS notes that occupational therapy assistants may advance by gaining additional education and becoming occupational therapists, a move that takes a graduate degree and a new license.

Local conditions vary, and national figures can hide a lot. Before taking an offer, compare it with the state and metro wage data BLS publishes for this occupation, and ask how the employer structures supervision, productivity expectations and documentation time, because those three things decide what the job feels like day to day.

Dear Ms. Alvarado,

I am applying for the Certified Occupational Therapy Assistant position at Riverbend Pediatric Therapy. I graduated from an occupational therapy assistant program this spring, passed my certification exam in July, and recently received my state license. My Level II fieldwork in an outpatient pediatric clinic and an elementary school convinced me that pediatrics is where I want to build my career.

At the clinic, I carried a caseload of children working on fine motor control, self-care and sensory regulation under my supervising OT's plans. One six-year-old with low muscle tone could not hold a pencil for more than a few seconds when I met him. We built his grip through clay, tongs and a shoebox obstacle course he named himself, and by the end of my placement he was writing his first name on a whiteboard for his mother. I learned to adjust an activity mid-session when a child shut down, and to write notes that showed my OT exactly what changed and why.

In the school placement, I ran a small handwriting group and worked with teachers to fit sensory breaks into the classroom routine without pulling students away from instruction. That taught me to explain therapy goals in plain language to people who are not clinicians.

I would bring Riverbend a strong work ethic, careful documentation habits and a genuine love of play-based treatment. I also speak conversational Spanish, which helped me communicate home programs to families during fieldwork.

My fieldwork supervisors described me as calm with anxious parents and quick to ask questions when a plan was unclear, and I intend to keep both habits as a new practitioner. Thank you for considering my application. I would welcome the chance to meet your team and observe a treatment day.

Sincerely, Jordan Pike, COTA/L
