The COTA (Certified Occupational Therapy Assistant) credential, issued by the National Board for Certification in Occupational Therapy (NBCOT), is the nationally required certification for occupational therapy assistants in the United States. Occupational therapy assistants work under the supervision of occupational therapists to help patients develop, recover, improve, and maintain the skills needed for daily living and working. This is a deeply rewarding healthcare career that combines clinical skills with creative problem-solving, offering strong job growth, meaningful patient impact, and competitive salaries with just an associate degree.

Certification Structure

Credential — COTA (Certified Occupational Therapy Assistant), issued by NBCOT
Prerequisites — Must graduate from an ACOTE (Accreditation Council for Occupational Therapy Education) accredited occupational therapy assistant program. Programs award an Associate degree and typically take 2 years to complete (some accelerated programs in 20 months)
Fieldwork Requirement — Must complete Level I and Level II fieldwork rotations (minimum 16 weeks of full-time Level II fieldwork) in clinical settings under OT supervision
Exam Format — NBCOT COTA exam is a computer-based test with approximately 200 multiple-choice questions (clinical simulation and multiple-choice format). Administered at Prometric testing centers year-round
State Licensure — All states require licensure to practice as an OTA. State licenses are typically based on passing the NBCOT exam. Note: felony convictions may affect ability to sit for the exam or obtain licensure
Renewal — NBCOT certification renewal required every 3 years with 36 professional development units (PDUs). State licensure renewal requirements vary

What You Will Learn

Foundations of OT — Occupational therapy theories, models of practice (MOHO, PEO, PEOP), therapeutic use of self, evidence-based practice, and the OT process (evaluation, intervention, outcomes)
Therapeutic Interventions — Activity analysis and adaptation, therapeutic exercise, functional mobility training, ADL/IADL training, splinting and orthotic fabrication, sensory integration techniques, and cognitive rehabilitation strategies
Population-Specific Practice — Pediatric OT (developmental delays, autism, sensory processing), adult rehabilitation (stroke, TBI, spinal cord injury, joint replacement), geriatric OT (dementia care, fall prevention, aging in place), and mental health OT (coping strategies, social skills, community reintegration)
Clinical Skills — Vital signs, range of motion measurement, manual muscle testing, transfer techniques, wheelchair management, adaptive equipment fitting, and home modification assessment
Documentation — SOAP notes, treatment plans, progress notes, discharge summaries, and insurance documentation for Medicare, Medicaid, and private payers
Professional Practice — Ethics, supervision requirements, interprofessional collaboration, cultural competency, and advocacy for occupational therapy services

Why This Certification Stands Out

Key advantages: (1) Exceptional job growth — BLS projects 22% growth for occupational therapy assistants through 2033, much faster than average, driven by aging population and increased recognition of OT value. (2) Meaningful work — OTAs directly help people regain independence in daily activities after illness, injury, or disability. (3) Diverse settings — Work in hospitals, rehabilitation centers, schools, skilled nursing facilities, home health, outpatient clinics, and mental health facilities. (4) Associate degree entry — Only 2 years of education required, making it one of the most accessible healthcare careers with strong salary potential. (5) Work-life balance — Many OTA positions offer regular weekday hours, especially in schools and outpatient settings. (6) Career advancement — COTAs can pursue specialty certifications, advance to supervisory roles, or use the OTA as a stepping stone to OTR (occupational therapist) education.

Career Outcomes

Occupational therapy assistants earn a median salary of $64,250/year (BLS, May 2024), with experienced COTAs in specialized settings earning $70,000–$85,000+. Travel OTAs can earn $1,600–$2,800/week. Top-paying industries include home healthcare services and nursing care facilities. Job growth of 22% projected through 2033 — approximately 8,600 new positions annually. Employment settings: skilled nursing facilities (27%), hospitals (18%), offices of physical/occupational therapists (14%), home health (11%), and schools (10%). COTA certification is universally required, creating a clear value proposition for the credential.

Who It Is For

Students in or considering ACOTE-accredited OTA programs, healthcare workers seeking a career with strong growth and meaningful patient impact, career changers attracted to a 2-year pathway into healthcare, individuals interested in pediatric therapy (schools are major employers of COTAs), people who enjoy creative problem-solving and helping others achieve independence, and those considering OTA as a foundation for eventually pursuing an OTR degree.
