Both the OTR and COTA exams are administered via computer-based testing.
OTR Exam Details: The OTR exam consists of three Clinical Simulation Test (CST) problems and 170 four-option multiple-choice questions.
The CST problems are particularly important as they simulate complex clinical scenarios where you must select relevant information and choose the best sequence of actions.
COTA Exam Details: The COTA exam consists entirely of 200 multiple-choice questions, which may include some multi-select items where more than one correct answer must be chosen.
Important Procedures: The time limit for both examinations is 4 hours, which is the actual testing time. This does not include a tutorial or any planned breaks.
The passing score for all NBCOT certification exams is a scaled score of 450, within a range of 300 to 600.
The exams are administered on a year-round basis, allowing for flexibility in scheduling once you have received your Authorization to Test (ATT) letter.
