Occupational Therapist Assistant Job Description
Occupational Therapist Assistants (OTAs) work under the supervision of licensed occupational therapists to carry out treatment plans that help patients recover or maintain daily living and work skills. They work with patients across ages and diagnoses — stroke survivors relearning to dress themselves, children developing fine motor skills, adults managing chronic pain — in hospitals, outpatient clinics, schools, and skilled nursing facilities.

Overview
Occupational Therapist Assistants bridge the gap between a treatment plan on paper and functional recovery in practice. The supervising occupational therapist evaluates the patient, establishes goals, and designs the plan. The OTA implements it — session by session, adjusting technique and pacing to what the patient can actually do that day.
In an inpatient rehabilitation setting, an OTA might work with a patient who had a hip replacement in the morning, a stroke survivor in the afternoon, and a patient with traumatic brain injury later in the day. Each session is about the same core question: what does this person need to be able to do, what can they do right now, and what's the next step? Activities range from purposeful reaching exercises and fine motor tasks to practicing transfers from bed to wheelchair, practicing meal preparation in a kitchen simulation area, or working through cognitive tasks with a patient managing early dementia.
In a school setting, the OTA might support a child with autism developing handwriting and self-care skills. In home health, the work focuses on making a patient's actual home environment work — recommending grab bars, practicing stair navigation, teaching a spouse how to assist safely without causing injury.
Documentation is a constant. Every session generates a note, and those notes support billing, track progress, and communicate findings to the supervising OT and the rest of the care team. OTAs who fall behind on documentation create problems that ripple across billing and compliance.
What makes OTA work demanding in a positive sense is the directness of the connection between what you do and what happens for the patient. When a 78-year-old woman who stopped cooking after her stroke makes scrambled eggs in the OT kitchen for the first time in six months, that's a concrete, immediate result.
Qualifications
Education:
- Associate of Applied Science in Occupational Therapy Assisting from an ACOTE-accredited program (required)
- Programs typically take two years; include fieldwork rotations in at least two clinical settings
- Some community colleges offer bridge pathways for CNAs, medical assistants, or PTAs already in healthcare
Licensure and certification:
- NBCOT OTA exam (passing required for COTA credential)
- State OTA license or registration (all 50 states require licensure)
- CPR/BLS certification (required at most employers)
- Fieldwork Level II completion in at least two distinct practice settings (ACOTE requirement)
Clinical skills that matter in practice:
- Manual skills: splint fabrication, therapeutic activity setup, safe patient handling techniques
- Transfer training: proper body mechanics for OTA and patient during bed-to-chair, standing pivot, and floor-to-standing transfers
- Functional assessment: Activity of Daily Living (ADL) scoring, grip strength measurement, range of motion goniometry
- Adaptive equipment: identifying, fitting, and training patients on devices from buttonhooks to powered wheelchairs
- Documentation: SOAP notes, functional outcome measures (FIM, COPM, Barthel Index)
Traits that predict clinical effectiveness:
- Patience — functional recovery is rarely linear, and frustration is contagious
- Physical stamina for a shift that involves considerable walking, lifting, and hands-on patient contact
- Adaptability: no two patients present the same way, and rigid protocol-following fails frequently in functional rehabilitation
Career outlook
The employment outlook for OTAs is stronger than most two-year healthcare careers. The Bureau of Labor Statistics projects OTA employment growth well above average through 2032, driven primarily by aging demographics. The population aged 65 and older is the fastest-growing patient segment, and that cohort has the highest per-capita demand for occupational therapy services — hip and knee replacements, stroke recovery, Parkinson's disease management, and fall prevention programs.
Skilled nursing facilities remain the largest employer of OTAs, but the outpatient setting is growing faster. As surgical outcomes improve and hospital stays shorten, more recovery work happens in outpatient clinics and at home. Home health OTA roles in particular are growing rapidly, and they typically offer schedule flexibility that appeals to OTAs managing personal commitments.
Travel OTA opportunities have expanded significantly since 2020. An experienced COTA willing to take 13-week contracts in underserved areas can earn $70–$90K in total compensation, with housing stipends pushing effective hourly compensation well above the permanent staff rates. For early-career OTAs looking to build clinical breadth quickly, travel is an efficient path.
The main constraint on practice growth is not demand but supply of OTs, since OTA practice requires OT supervision. Telehealth models are being explored for OT supervision in rural settings, which may expand OTA deployment in geographic areas currently underserved.
Career advancement for OTAs typically goes toward clinical specialization (hand therapy, pediatrics, low vision, driving rehabilitation), supervision of OTA students, or the path to completing an OT bridge program and becoming a licensed occupational therapist. The OTA-to-OT bridge track is becoming more accessible as more programs offer it in an accelerated format.
Sample cover letter
Dear Hiring Manager,
I'm applying for the Occupational Therapist Assistant position at [Facility]. I completed my AAS in Occupational Therapy Assisting at [College] in December and passed the NBCOT exam in February. My Level II fieldwork included 10 weeks in acute rehabilitation at [Hospital] and 8 weeks at a pediatric outpatient clinic, and I've been working as a rehab aide at a skilled nursing facility while completing the licensure process.
At [Hospital]'s acute rehab unit I worked alongside two OTs with a mixed caseload — mostly CVA, TBI, and post-surgical orthopedic patients. The experience I found most instructive was working with patients who had significant motivation deficits after stroke. I learned that choosing the right activity matters as much as the correct therapeutic goal: a patient who refused standard ADL practice would engage fully when the activity connected to something she cared about before the stroke. I started paying more attention to intake interviews and brought what I learned there into every session.
At [Clinic] I had pediatric experience with sensory processing and fine motor delays, including designing and running a small group for four-year-olds working on pre-writing skills. I'm comfortable with pediatric caseloads and enjoy them, but my primary interest is in adult rehabilitation.
I'm a reliable documentor — notes completed same shift, always. I know that sounds like a low bar, but in skilled nursing settings it matters operationally and financially.
I'd welcome the chance to speak about this position and what your team needs in a new OTA.

Frequently asked questions
- What does an Occupational Therapist Assistant do?
- Occupational Therapist Assistants (OTAs) work under the supervision of licensed occupational therapists to carry out treatment plans that help patients recover or maintain daily living and work skills. They work with patients across ages and diagnoses — stroke survivors relearning to dress themselves, children developing fine motor skills, adults managing chronic pain — in hospitals, outpatient clinics, schools, and skilled nursing facilities.
- What are the main duties of an Occupational Therapist Assistant?
- Core duties include: carry out treatment sessions based on occupational therapist-developed care plans, documenting patient progress after each visit; guide patients through therapeutic exercises and activities targeting fine motor skills, strength, coordination, and cognitive function; and teach adaptive techniques for bathing, dressing, eating, and meal preparation using assistive devices when needed.
- What does COTA certification require?
- Candidates must complete an accredited associate degree program in occupational therapy assisting (ACOTE-accredited), pass the NBCOT OTA certification exam, and obtain a state license. Most states require continuing education for license renewal every two years. The COTA credential must be maintained through NBCOT's certification renewal cycle.
- How much supervision does an OTA receive from an occupational therapist?
- Supervision requirements vary by state and setting, but OTAs may not evaluate patients or establish treatment goals independently — those responsibilities remain with the supervising OT. In most outpatient and inpatient settings, OTs and OTAs work in proximity and communicate daily. In home health, supervision is less frequent but still required at defined intervals per state board rules.
- What is the difference between an OTA and a physical therapist assistant?
- Physical therapist assistants (PTAs) focus on restoring physical mobility, strength, and pain management. OTAs focus on functional independence in daily activities — getting dressed, cooking, returning to work, managing a home. There is significant overlap in therapeutic exercise, but the clinical lens and treatment goals differ. Many rehabilitation settings employ both.
- Will AI or automation affect OTA roles?
- Documentation tools and scheduling software are becoming more AI-assisted, which reduces administrative time. However, the hands-on, relationship-based nature of OTA work — helping a stroke patient button a shirt for the first time, adjusting a splint for comfort — is not a task machines replace. Demand is driven by demographics, not technology cycles.
- What work settings do OTAs practice in?
- Skilled nursing facilities and acute care hospitals are the largest employers. Outpatient rehabilitation clinics, home health agencies, schools (for pediatric OTA), and early intervention programs are also common. Some OTAs work in mental health settings, hand therapy clinics, or corporate ergonomics programs. The variety of settings is one of the career's strengths.
