The BJCP Beer Judging Examination is closed book and requires the judging of six beers as if one were at a competition, with the scoresheets evaluated on the basis of scoring accuracy, perception, descriptive ability, feedback and completeness. Grading is done by volunteer National and Master judges, with their scores and feedback reviewed by both a BJCP Associate Exam Director and a BJCP Exam Director. These reviews ensure that the scores from different exams and graders are consistent between different exams and with the criteria expected for the different judging levels. .
