In all cases where the NPPE exam is used, the score of the multiple-choice-question exam is based on the number of questions correctly answered, expressed as a percentage. A correctly answered question scores 1 point and there is no penalty for incorrect or unanswered questions. Nevertheless, the exam is graded on a curve, and a statistically equated score of 65% minimum is required to pass the multiple-choice-question exam. Please, refer to the NPPE Candidate Guide for more detailed information.
