Occupational therapy is one of the fastest-growing healthcare fields in the U.S., with more than 160,000 professionals employed and projected growth of 14% from 2024 to 2034 according to the Bureau of Labor Statistics (BLS). Yet, many people confuse the roles of Occupational Therapy Assistants (OTAs) and Certified Occupational Therapy Assistants (COTAs).
This article breaks down what separates the two—from education and certification requirements to salary, job outlook, and career advancement. By the end, readers will understand which path best fits their goals in this expanding healthcare profession.
Key Things You Should Know About COTA vs. OTA
COTA means certification. All Certified Occupational Therapy Assistants (COTAs) are OTAs who have passed the NBCOT exam, which validates their professional competency. Without this certification, graduates cannot legally practice as occupational therapy assistants in most states.
Education defines entry level. OTAs typically hold an associate degree from an accredited occupational therapy assistant program, while occupational therapists (OTRs) require a master’s degree. This educational gap leads to different roles, autonomy levels, and pay scales in clinical practice.
Job demand is strong. The occupational therapy field is projected to grow 14% from 2024 to 2034—much faster than average. Demand for assistants remains equally high as aging populations and rehabilitation programs expand nationwide.
The main difference between a COTA (Certified Occupational Therapy Assistant) and an OTA (Occupational Therapy Assistant) is certification. Every COTA is an OTA who has passed the National Board for Certification in Occupational Therapy (NBCOT) exam, while an OTA without certification cannot legally practice or use the title “COTA.”
In short, OTA refers to the educational background, and COTA refers to professional licensure and credentialing.
OTAs complete an associate degree from an accredited occupational therapy assistant program that includes classroom study and supervised clinical practice. After graduation, they must pass the NBCOT certification exam to become licensed as COTAs. This certification confirms that the practitioner meets national competency standards and is qualified to work directly with patients under the supervision of an occupational therapist (OTR).
While both roles perform similar hands-on rehabilitation tasks—such as helping patients regain daily living skills—only COTAs have the authority to implement therapy plans in clinical settings. Most employers require certification before hiring, making the COTA credential essential for employment and career progression. The distinction also affects salaries and advancement opportunities, as certified practitioners often earn higher pay and have access to broader clinical roles.
The distinction between certification and education in this field mirrors the difference between a licensed and certified massage therapist, where licensing provides legal permission to practice, and certification confirms professional skill and competence.

How do you become a COTA vs an OTA?
To become an OTA or COTA, candidates must follow a structured educational and licensing process that ensures competency and professional readiness. The key difference is that COTAs complete certification after meeting OTA educational requirements.
Steps to Become an OTA:
Earn an Associate Degree – Complete a two-year ACOTE-accredited occupational therapy assistant program combining classroom and clinical training.
Finish Supervised Fieldwork – Complete hands-on clinical placements in rehabilitation or healthcare settings to gain direct patient experience.
Graduate and Apply for Certification – After finishing coursework and fieldwork, graduates become eligible for NBCOT certification.
Steps to Become a COTA:
Pass the NBCOT Exam – Successfully complete the National Board for Certification in Occupational Therapy (NBCOT) exam to earn the COTA credential.
Apply for State Licensure – Obtain a license to practice in your state; requirements may vary by location.
Maintain Certification – Renew every three years with continuing education credits to stay current in practice standards.
This progression—from education to certification—mirrors the broader professionalization process seen in related fields such as how to become an online therapist, where accredited training and licensure are equally essential.

3. What do COTAs and OTAs do day-to-day — what are their responsibilities and limits?
COTAs and OTAs support occupational therapists by carrying out treatment plans, assisting patients with daily living skills, and documenting progress, but they differ in their scope and level of independence. OTAs complete the accredited coursework and fieldwork but have not yet earned the NBCOT certification, while COTAs hold the credential that confirms their competence to practice under supervision.
Typical Responsibilities of COTAs and OTAs:
Direct Patient Care: Assist patients with activities of daily living (ADLs), from dressing and grooming to mobility and feeding exercises, as outlined in individualized therapy plans.
Therapeutic Interventions: Implement prescribed rehabilitation exercises, adaptive equipment training, or sensory activities in school, home health, or clinical settings.
Documentation and Reporting: Record patient progress, note functional changes, and communicate updates to the supervising occupational therapist.
Equipment Management: Fit and monitor the use of adaptive devices like wheelchairs, splints, and braces to support patient independence.
Education and Support: Teach caregivers, teachers, or family members how to reinforce therapy goals at home or in community settings.
Limits:
COTAs and OTAs cannot independently evaluate patients or create treatment plans; only licensed occupational therapists can do initial assessments and modify care goals.
Their interventions must be supervised and signed off by an OT to ensure compliance with clinical and legal standards.
Day-to-day, a COTA might spend the morning in a skilled nursing facility running group exercise sessions, while an OTA in training might shadow an occupational therapist during evaluations and help prepare adaptive equipment for afternoon pediatric sessions. This split between hands-on care and supervised limits ensures both patient safety and practitioner development.
Much like in healthcare administration or construction industries, this division of duties aligns with choosing between should you get a certificate or degree in construction management, where both credentials lead to practical roles but vary in depth of responsibility and long-term advancement potential.
How does salary for OTAs/COTAs compare to full OTs and how does certification impact pay?
Certified Occupational Therapy Assistants (COTAs) and Occupational Therapy Assistants (OTAs) earn significantly less than fully licensed Occupational Therapists (OTs), primarily due to differences in education, licensure, and responsibility. According to the Bureau of Labor Statistics, the median annual salary for OTs is $98,340, with the top 10% earning about $128,740 and the lowest 10% earning $64,640. By comparison, most COTAs earn between $55,000 and $63,000 per year based on employer listings and aggregate data from Zippia and ZipRecruiter.
Certification makes a clear difference. OTAs without the NBCOT credential often work under provisional or supervised titles with limited earning potential. Once certified as COTAs, they typically qualify for higher pay, full-time roles, and benefits, since certification signals verified clinical competence and compliance with state licensure standards. Experienced COTAs working in skilled nursing facilities or home health settings tend to earn on the higher end of the range.
To reach higher income brackets, many assistants eventually pursue a master’s degree to become registered OTs—a pathway explored in guides on how to make six figures as a therapist.
The chart below compares salary percentiles for full OTs in the United States, showing the range of potential earnings across experience levels and career progression.
What is the job outlook and demand for OTAs/COTAs in 2026?
The job outlook for OTAs and COTAs in 2025 is exceptionally strong, reflecting broader growth in the rehabilitation and allied health fields. According to the BLS, employment for occupational therapists is projected to grow 14% from 2024 to 2034, much faster than the average for all occupations. This increase directly fuels demand for assistants who work under licensed therapists in hospitals, skilled nursing facilities, and home health agencies.
Several factors drive this trend. The aging U.S. population, rising rates of chronic conditions, and increased emphasis on long-term recovery and independent living have made therapy services indispensable. As OTs expand their caseloads, COTAs become essential for implementing treatment plans, documenting progress, and managing patient care continuity. This combination of accessibility and growing clinical need ensures sustained job security and advancement opportunities across the country.
The infographic below highlights projected growth and annual openings, showing how rising demand for rehabilitation professionals translates into expanding opportunities for OTAs and COTAs nationwide.
This strong job growth trajectory parallels trends in technology and healthcare crossover fields such as difference between cybersecurity and data security, where new specializations emerge to meet the increasing complexity and demand of modern systems.
What are the pros and cons of becoming a COTA/OTA vs going full OT?
The main difference between becoming a COTA/OTA and a full Occupational Therapist (OT) lies in the level of responsibility, required education, and long-term earning potential. COTAs and OTAs can enter the workforce faster, but OTs enjoy higher pay and more autonomy in clinical decision-making.
Pros of Becoming a COTA/OTA:
Faster entry into the field. Most OTA programs take about two years, compared to the master’s or doctorate required for OTs, which can take six or more years to complete.
Lower educational cost. The average in-state tuition for OT graduate programs exceeds $11,000 per year, while associate programs cost significantly less.
High job demand. With occupational therapy jobs projected to grow 14% from 2024 to 2034, assistants are seeing consistent employment opportunities across hospitals, schools, and home health care.
Cons of Becoming a COTA/OTA:
Lower salary ceiling. Certified assistants earn less than licensed OTs—the median annual wage for OTs is $98,340, while OTAs generally earn 25–30% less.
Limited independence. COTAs must work under OTs’ supervision and cannot conduct evaluations or develop treatment plans independently.
Restricted advancement. Career progression is narrower without returning to school for a higher OT degree.
Overall, becoming a COTA/OTA offers a quicker and more affordable route into a growing healthcare field, while full OT licensure provides greater autonomy and long-term financial reward.
This trade-off between speed and scope of education is similar to the choice between MBA vs BBA which is better, where both paths can lead to rewarding careers—but one emphasizes early workforce entry while the other focuses on leadership and higher earning potential.
Can an OTA or COTA advance or transition into being an OT?
Yes. OTAs and COTAs can advance to become licensed Occupational Therapists (OTs) through bridge programs designed to recognize prior education and clinical experience. This transition typically involves earning a bachelor’s degree if not already held, then completing an accredited master’s or doctoral program in occupational therapy.
Most bridge pathways require a valid COTA license, professional work experience (often around 1,500 hours), and prerequisite coursework in anatomy, physiology, and psychology. After completing the program, candidates must pass the NBCOT exam for OTs and obtain state licensure. According to the BLS, occupational therapists earn a median of $98,340 per year, offering a clear financial incentive for assistants looking to advance.
While the process demands commitment and academic rigor, the result is increased autonomy and expanded career options, including supervisory or specialist roles. For reference, see Research.com’s guide on what degree do you need to be a therapist, which outlines similar educational progression models across healthcare fields.
What skills, certifications, or specialties can boost OTA/COTA career prospects?

Fieldwork Requirements: Look for programs that include Level I and II fieldwork placements. These provide hands-on clinical experience and mentorship under licensed OTs in hospitals, schools, or rehab centers.
Tuition and Fees: Based on CollegeTuitionCompare, average annual costs are around $11,379 in-state and $33,643 out-of-state for undergraduate OT-related programs. Graduate programs average $11,368–$23,777 depending on residency.
Program Duration: Most OTA programs take about 2 years to complete, while advancing to OT typically adds another 2–3 years of graduate study.
When evaluating options, consider aligning your specialization with long-term career goals. Research.com’s guide on in demand therapy specialization offers insight into areas with strong growth and competitive pay, such as pediatrics and geriatrics.
What challenges do COTAs/OTAs face?
COTAs and OTAs face several professional challenges despite their essential role in patient recovery and care delivery. The most common include supervision requirements, scope-of-practice restrictions, and limited upward mobility compared to fully licensed Occupational Therapists (OTs).
Key challenges include:
Mandatory Supervision: COTAs must work under the direction of an OT, which limits their autonomy in clinical decision-making and treatment planning. They can implement plans but cannot independently modify them without OT approval.
Scope Limitations: While OTAs handle direct patient interaction and documentation, only OTs can conduct evaluations and determine treatment goals. This dependency can restrict practice flexibility, particularly in smaller facilities.
Career Ceiling: Advancement options for COTAs are often limited unless they pursue additional education to become OTs. Although COTAs can specialize in pediatrics, geriatrics, or hand therapy, managerial or academic roles typically require a master’s degree.
Pay Gap and Workload: According to BLS, full OTs earn a median of $98,340, while assistants earn significantly less, reflecting differences in education and responsibility.
For those aiming to break through these ceilings, Research.com’s guide on the fastest way to become a therapist outlines strategic educational routes to progress quickly toward independent practice.
The chart below highlights tuition and cost considerations for OT-related programs, emphasizing how financial barriers can compound these professional challenges.
