There are 175 questions over 3 hrs on this examination. Of these, 150 are scored questions and 25 are pretest questions that are not scored. Pretest questions are used to determine how well these questions will perform before they are used on the scored portion of the examination. Scores on ANCC examinations are reported on a scale with a maximum possible score of 500. To pass the ANCC examination, an examinee must achieve a scale score of 350 or higher. Prior to conversion of an examinee’s score to this scale, the examinee’s raw score on the examination is determined, which is simply the number of test items that the examinee answered correctly (e.g., 105 out of 150). The raw score is then converted to a scale score, using a conversion formula.
