What happens if I fail the NBCOT COTA exam?

Candidates must wait 45 days between exam attempts. There is no limit on retakes, but each attempt requires the full exam fee. Analyze your score report to identify weak domains and focus preparation accordingly. Many candidates pass on their second attempt.

What is the difference between COTA and OTR?

COTA (Certified Occupational Therapy Assistant) requires an associate degree and works under the supervision of an OTR. COTAs primarily implement interventions selected by the OTR. OTR (Occupational Therapist Registered) requires a master's or doctoral degree, can evaluate clients independently, and directs the OT plan of care. Both must pass NBCOT certification exams.

Can a COTA become an OTR?

Yes, COTAs can pursue bridge programs that allow them to advance from associate-level to master's-level education. These programs recognize the COTA's experience and education, typically reducing the time needed to complete the OTR degree. After graduating from an ACOTE-accredited program, the COTA can take the NBCOT OTR exam.
