By law, an Occupational Therapy Assistant (OTA) must work under the supervision of an Occupational Therapist (OT). The OT will be the individual who leads the intervention process and is the occupational therapy practitioner most likely to evaluate, write treatment reports, create goals for intervention, and make final recommendations for discharge. The OTA and OT both work directly with patients to achieve their therapeutic goals. An effective OT/OTA team collaborates to provide the most effective treatment possible. An OTA will need to utilize clinical reasoning skills under the supervision of the OT to decide what methods will best help a client meet their OT goals.
