OT vs OTA vs Occupational Therapy Aide

Key points

• An occupational therapist (OT) and an occupational therapy assistant (OTA) are different professional roles with different entry-level degrees and credentials. An aide is a third, non-professional role.
• Never assume a program for one role qualifies you for another.
• A degree alone does not grant a license, and admission does not guarantee that you will be eligible for certification.
• Licensure is set by each state. Check your state board.

Three job titles sound similar and are easy to confuse when you browse programs. They differ in what you study, what credentials you can hold and what you are allowed to do.

Occupational therapist (OT)

NBCOT describes the OTR, Occupational Therapist Registered, as the professional who evaluates the client, plans therapeutic interventions and completes discharge documents. To reach that role in the United States you complete an entry-level occupational therapy degree from an ACOTE-accredited program, pass the NBCOT certification exam and meet your state’s licensing requirements.

The Bureau of Labor Statistics (BLS) states that occupational therapists typically need a master’s degree in occupational therapy to enter the occupation, and that all states require licensure. Doctoral entry-level programs also exist; see master’s vs OTD. Browse master’s programs and entry-level OTD programs.

Occupational therapy assistant (OTA)

NBCOT describes the COTA, Certified Occupational Therapy Assistant, as the professional who implements and documents the therapeutic interventions. BLS states that OTAs typically need an associate’s degree from an accredited program, although some bachelor’s programs exist, and that they usually need a state license. The title COTA comes with passing the exam.

OTAs work within a team led by occupational therapists. See OTA programs and the guide on becoming an OTA.

Occupational therapy aide

BLS states that aides typically need a high school diploma or equivalent, followed by on-the-job training, and that aides are typically not regulated by state law. An aide is not an OTR or COTA and does not hold NBCOT certification. Training for an aide job is not an ACOTE-accredited degree and does not lead to eligibility for the certification exam.

Side-by-side

BLS describes the typical entry route, not the only one. ACOTE also accredits OT programs at the doctoral level and OTA programs at the baccalaureate level, and its school directory lists OTA associate, OTA baccalaureate, OT master’s and OT doctorate programs separately.

Do not mix up the pathways

• An OTA associate degree is not an OT degree. Moving from OTA to OT usually means applying to an OT program; whether any credit transfers is each school’s decision.
• A short course or certificate in rehabilitation, anatomy or aide work is not NBCOT certification and does not qualify you as an OT or OTA. See certificates vs professional certification.
• A graduate of a program that is not ACOTE-accredited is not eligible for the NBCOT exam through that program. ACOTE warns that there is risk in entering a program that is not fully accredited. See ACOTE accreditation and our accreditation page.

Choosing between them

Think about the role you want to hold, how long you want to study and what you want to be responsible for in practice. The OT role is the one that evaluates and plans; the OTA role carries out the plan within the team. Compare programs on the compare page and see how we record data on the methodology page.
