Who it’s for
Built for the people taking this exam.
Graduates of ACOTE-accredited OTA associate-degree programs pursuing initial certification and state licensure as a Certified Occupational Therapy Assistant.
Why it matters in 2026
The career signal.
Distinct from NBCOT OTR: COTAs work under the supervision of registered OTs and cannot independently evaluate or set treatment plans. Every state requires the COTA credential for OTA licensure, and the exam is the single gate between OTA program graduation and clinical income — typically among the highest-paying associate-degree healthcare roles per BLS data.
