Every state licenses occupational therapists and OT assistants on NBCOT certification: an ACOTE-accredited degree with its Level II fieldwork, then NBCOT's exam (the OTR exam for OTs, 180 questions in 4 hours; the COTA exam for OT assistants, 190 questions in 4 hours; 450 on a 300-600 scale passes; $540 to apply online). NBCOT certification is not a license: you apply to your state board separately, and NBCOT sends the board your score (the Score Transfer is free if you add it when you apply for the exam, $35 later).
