Occupational therapy practitioners help clients across the life span reach functional goals related to play, work, education and self care. The roles and skills which underlie these goals are in essence one’s occupation and occupational tools. The Certified Occupational Therapy Assistant will be able to provide direct service to the client under the supervision of the Registered Occupational Therapist. The level of supervision is dependent on the specific service provided and the competency of the occupational therapy assistant.
