The number of items that you answered correctly, which is your “raw score,” has been converted, or transformed, to a scaled score, which is referred to as a “standard score” in your report. The conversion is similar to converting a weight from pounds to kilograms. The points on the scales differ, although the weight is the same. The scale used for the CRN examination has a mean (average) score of 100, and a standard score of 95 is required to pass the exam. To reach the passing standard score of 95, you must answer about 73% of the questions in the total test correctly.
