Final answer:
The occupational therapist is responsible for all aspects of screening, evaluation, and re-evaluation in the OT process, following AOTA standards.
Step-by-step explanation:
The AOTA (American Occupational Therapy Association) standards of practice clearly indicate that it is the occupational therapist who is responsible for all aspects of screening, evaluation, and re-evaluation during the occupational therapy (OT) process. While occupational therapy assistants and other healthcare professionals, such as certified nursing assistants and physical therapists, play critical roles in patient care, they do not have the same level of responsibility or training in occupational therapy as an occupational therapist. Occupational therapists hold a minimum of a master's degree and are extensively trained in assessing and developing individualized treatment plans for those with physical, mental, or developmental conditions.
