Determination of the Passing Score

The passing score for the Emergency Number Professional Certification Examination is set by the NENA Institute using a method called the modified-Angoff approach. This method asks each individual to make a judgment about the probability that a minimally competent candidate who meets the eligibility requirements would answer the questions correctly. The overall passing score is computed as the average of the estimated probabilities for each question.The passing score that is set by the NENA Institute represents a level of competency that must be demonstrated to pass the examination.
