A certified therapy assistant has a 2-year degree from an accredited program of occupational therapy or physical therapy. Education is focused on intervention strategies and methods. They are under the direct supervision of the OTR or DPT, meeting weekly and carrying out the written plan of care. They do not participate in the evaluation process, however, are highly skilled in helping clients meet their goals based on the evaluation and treatment plan. When a certified therapy assistant sees a cleint, that session is billed under their supervising registered and licensed therapist (so on a client invoice, it will show up as the supervising therapists name, no the assistants name).
