Occupational therapy assistants (OTAs) work directly with patients to help them regain or develop the skills needed for everyday life. They guide people through therapeutic activities, teach them how to use adaptive equipment, and track their progress over the course of treatment. OTAs do this work under the supervision of a licensed occupational therapist (OT), but they are often the practitioner spending the most hands-on time with clients during each session.
Core Responsibilities
The bulk of an OTA’s day involves carrying out the treatment plans that an occupational therapist has designed. In practice, that means working one-on-one or in small groups with clients on specific goals: helping someone relearn how to dress themselves after a stroke, guiding a child through play activities that build coordination and social skills, or teaching a person with Parkinson’s disease how to use adaptive devices for meal preparation.
OTAs also help injured workers return to their jobs by teaching them ways to compensate for lost motor skills. For people with developmental or intellectual disabilities, the work might focus on life skills like money management, socialization, or navigating public transportation. The thread connecting all of these tasks is the same: helping people participate in the activities that matter to them.
Beyond direct treatment, OTAs are responsible for documenting each session. That includes recording what interventions were used, how the client responded, and whether progress is being made toward their goals. This documentation feeds back to the supervising occupational therapist, who uses it to adjust the treatment plan over time.
How OTAs Work With Occupational Therapists
The relationship between an OTA and an OT is a structured partnership, not just a loose arrangement. The occupational therapist is responsible for the entire evaluation process: determining whether a client needs services, defining the problems to address, setting goals, and building the intervention plan. An OTA cannot independently evaluate a new patient or create a treatment plan from scratch.
What the OTA can do is contribute to the evaluation by performing specific assessment tasks that the OT has delegated, then reporting the results back. Once a treatment plan is in place, the OTA takes the lead on carrying it out session by session. The OT must stay directly involved at the initial evaluation and check in regularly throughout the course of care, but the OTA handles much of the day-to-day therapeutic work. Both practitioners share responsibility for making sure supervision is appropriate and consistent. State laws vary on exactly how much oversight is required, with some states mandating a specific ratio of supervisory check-ins.
Where OTAs Work
OTAs practice across a wide range of settings. Skilled nursing facilities and rehabilitation centers are among the most common, where they help older adults recover from falls, surgeries, or strokes. Hospitals employ OTAs in both inpatient and outpatient rehabilitation units. Schools hire them to support children with disabilities or developmental delays, often working alongside teachers and special education staff to help kids meet developmental milestones and succeed in the classroom.
Home health is another growing area. In this setting, the OTA visits clients in their own homes and helps them practice daily tasks in the environment where they actually live. This can include everything from bathroom safety training to reorganizing a kitchen so someone with limited mobility can prepare meals independently. Some OTAs also work in mental health settings, outpatient clinics, or community programs focused on helping people with disabilities build independence.
Education and Certification
Becoming an OTA requires graduating from an accredited occupational therapy assistant program, which typically takes about two years and results in an associate degree. These programs include both classroom instruction and hands-on clinical fieldwork where students practice skills with real patients under supervision.
After graduation, candidates must pass the national certification exam administered by the National Board for Certification in Occupational Therapy (NBCOT). Passing this exam earns the credential of Certified Occupational Therapy Assistant (COTA). Most states also require a separate state license or registration before you can begin practicing. Continuing education is required to maintain both national certification and state licensure.
Specialization Options
OTAs who want to deepen their expertise in a particular area can pursue board certifications through the American Occupational Therapy Association. Three advanced certifications are currently available: gerontology (working with older adults), pediatrics (children, youth, and families), and physical rehabilitation (recovery across diverse rehab settings). These certifications recognize specialized knowledge beyond entry-level training and can strengthen an OTA’s professional standing and career options.
Even without formal board certification, many OTAs develop informal specializations over time simply by working in the same setting for years. An OTA who spends a decade in a school system, for instance, builds deep practical expertise in pediatric interventions that goes well beyond what their original degree program covered.
What a Typical Day Looks Like
A typical OTA schedule involves seeing multiple clients throughout the day, with sessions usually lasting 30 to 60 minutes each. Between sessions, there’s documentation to complete and communication with the supervising OT about client progress or concerns. In a skilled nursing facility, a morning might start with helping a resident practice getting in and out of bed safely, followed by a session focused on fine motor exercises for someone recovering hand function after surgery. An afternoon could include group activities designed to improve cognitive skills or social engagement.
In a school setting, the rhythm is different. An OTA might pull students out of class individually or work with them in small groups, focusing on handwriting, sensory processing strategies, or self-care skills like buttoning a coat or opening a lunch container. The work is physical, often creative, and requires building genuine rapport with clients who may be frustrated, in pain, or resistant to therapy. OTAs who thrive in this role tend to be patient, adaptable, and genuinely motivated by helping people regain independence in the parts of life most people take for granted.
