As I previously mentioned, the NBCOT exam includes scored and non scored items. The non scored questions are field testing items. These items have performance data analyzed to determine their validity and reliability. The information obtained from non scored items helps determine how or if the items will appear on future versions of the exam. When taking the exam, the candidate cannot tell which items are scored and which are not. These unscored items are collected and reviewed with predetermined psychometric measures. When a field tested question meets the psychometric standards, it goes into the pool of items for future scored questions. If a question does not meet the metrics, it is reviewed, revised, and field tested again. To ensure both fairness and quality control, Item Response Theory methodology is used to analyze test items. Using this information when developing the exam questions helps the developers assure that they choose appropriate items. NBCOT uses these metrics to ensure the exams are reliable and valid from year to year. Using these metrics lets the agency provide performance feedback to the candidates quickly.
REVIEW Right now, let’s review what you have learned before I present your ten question quiz. The NBCOT is a nonprofit organization charged with certifying occupational therapists in the United States. The Board develops the standards for the field and assures that those standards are current with the best available practices. Finally, they develop and administer the certification exams for both the COTA and OTR. The procedures, policies, and structure of the organization itself are designed to handle any conflict of interest claims. They ensure that the testing process is objective for everyone. The NBCOT is responsible for the Practice Standards and Code of Conduct for occupational therapists. They also handle discipline through their Procedures for Enforcement.
