Occupational Therapy Assistants (OTAs) play a vital role in helping patients develop, recover, and maintain the daily living and work skills they need to lead independent, productive lives. Working under the supervision of a licensed occupational therapist (OT/OTR), OTAs are in high demand across hospitals, rehabilitation centers, schools, nursing homes, and home health agencies nationwide.

This guide walks you through every step of the process, from completing an ACOTE-accredited education program to passing the NBCOT exam, meeting state licensure requirements, and staying current with continuing education. We have also compiled verified data for all 51 states we track so you can compare requirements side by side.

What Does an Occupational Therapy Assistant Do?

Occupational Therapy Assistants work under the supervision of a licensed occupational therapist (OT/OTR) to help patients develop, recover, and maintain the daily living and work skills needed for independent living. OTAs implement treatment plans designed by the supervising OT, lead therapeutic activities, teach patients adaptive techniques and the use of assistive equipment, and document patient progress.

OTAs work across a broad range of settings and with diverse populations, including:

• Hospitals and rehabilitation centers: Helping stroke patients and individuals recovering from surgery or injury regain fine motor skills, balance, and daily functioning.
• Schools: Supporting children with developmental delays, autism, sensory processing disorders, and physical disabilities to participate in classroom activities and develop age-appropriate skills.
• Nursing homes and long-term care: Working with elderly patients, including those with dementia, to maintain independence in activities of daily living (ADLs) such as dressing, bathing, and eating.
• Home health: Providing therapy in patients' homes to help them adapt their living environment and routines after illness or injury.
• Outpatient clinics: Treating injured workers returning to their jobs, patients with chronic conditions, and individuals seeking to improve hand function or upper extremity strength.

According to the U.S. Bureau of Labor Statistics, the median annual wage for occupational therapy assistants is approximately $64,000--$66,000. Salaries vary by setting, geographic location, and experience, with higher pay often found in home health, skilled nursing facilities, and states with strong demand.

Step 1: Education -- ACOTE-Accredited OTA Programs

To become an OTA, you must graduate from a program accredited by the Accreditation Council for Occupational Therapy Education (ACOTE). ACOTE is the nationally recognized accrediting body for occupational therapy and occupational therapy assistant education programs in the United States.

Associate's Degree (Most Common Path)

The most common path to becoming an OTA is an associate's degree program, typically taking two years to complete. These programs are offered at community colleges and technical schools across the country and combine classroom instruction with hands-on clinical experiences.

Bachelor's Degree and the 2028 Transition

Some programs offer a bachelor's degree option for OTAs. Notably, ACOTE has announced a transition to baccalaureate-level entry for occupational therapy assistants by 2028. This means future OTA programs will increasingly require a four-year degree. Students currently enrolled in or entering associate's-level programs should confirm their program's accreditation timeline and status.

Typical OTA program coursework includes:

• Human anatomy and physiology
• Kinesiology
• Occupational therapy theory and practice
• Therapeutic media and activities
• Psychosocial intervention
• Pediatric occupational therapy
• Geriatric occupational therapy
• Medical conditions and pathology

Fieldwork Requirements

All ACOTE-accredited OTA programs require completion of both Level I and Level II fieldwork:

• Level I Fieldwork: Introductory experiences that provide observation and participation in occupational therapy settings. These occur throughout the didactic portion of the program and expose students to different practice areas and patient populations.
• Level II Fieldwork: Full-time clinical placement(s) totaling a minimum of 16 weeks. Students work under the supervision of a licensed OT or OTA and apply their knowledge in real clinical settings. Level II fieldwork must be completed within 18 months of finishing the didactic coursework.

Step 2: The NBCOT Exam -- Earning the COTA Credential

After graduating from an ACOTE-accredited program, you must pass the certification exam administered by the National Board for Certification in Occupational Therapy (NBCOT). Passing this exam earns you the COTA (Certified Occupational Therapy Assistant) credential, which is required for state licensure in most states.

Key exam facts:

• Format: Approximately 200 multiple-choice questions delivered via computer-based testing.
• Duration: 4 hours.
• Eligibility: Must have graduated from an ACOTE-accredited OTA program and completed all fieldwork requirements.
• Content areas: Acquiring knowledge of OT principles and evidence, applying OT processes and interventions, and managing OT services.
• Credential earned: COTA (Certified Occupational Therapy Assistant). After passing, many practitioners use the designation "COTA/L" to indicate both national certification and state licensure.
• Retakes: Candidates who do not pass may retake the exam. NBCOT allows a maximum of three attempts within the first year of eligibility.

Most candidates prepare using NBCOT's official study resources, review courses, and practice exams. Thorough preparation focusing on clinical reasoning and application of OT principles is essential for success.

Occupational Therapy Licensure Compact

The Occupational Therapy Licensure Compact is an interstate agreement that allows occupational therapy practitioners -- including OTAs -- to practice across member states without obtaining a separate license in each state. This is particularly beneficial for OTAs who work in telehealth, travel therapy, or near state borders.

Of the 51 states we track, 31 are members of the OT Compact. Member states include:

To practice under the compact, you must hold an active, unencumbered license in your home state and meet the compact's eligibility requirements. The compact does not replace state licensure -- it creates a streamlined pathway for multi-state practice.

Supervision Requirements for OTAs

OTAs practice under the supervision of a licensed occupational therapist (OT/OTR). Supervision is a fundamental aspect of OTA practice -- OTAs cannot practice independently. The supervising OT is responsible for evaluating patients, developing treatment plans, and overseeing the OTA's delivery of services.

Of the 51 states we track, 51 require formal OT supervision of OTAs. Supervision ratios and requirements vary by state:

Continuing Education Requirements

Maintaining your OTA license requires ongoing continuing education (CE). Requirements exist at the state level and vary by jurisdiction. Across the 51 states we track, the average CE requirement is 20.5 hours per renewal cycle.

Common CE topics for OTAs include:

• Ethics and professional conduct in occupational therapy practice
• Evidence-based interventions for specific populations (pediatrics, geriatrics, neurorehabilitation)
• Infection control and safety
• State-specific laws and regulations governing OT practice
• Specialized techniques such as hand therapy, sensory integration, or assistive technology

Tips for managing CE requirements efficiently:

• Track your hours year-round rather than scrambling at renewal time. Many state boards offer online CE tracking portals.
• Attend your state OT association's annual conference -- it typically offers multiple CE hours in a single weekend and is a strong networking opportunity.
• AOTA and NBCOT both offer approved CE activities, including online courses, webinars, and self-study modules.
• Check whether your state accepts NBCOT's professional development units (PDUs) toward state license renewal -- many do.
